Hydrogenated Castor Oil

Hydrogenated Castor Oil is a wax-like hydrogenated derivative of castor oil. Hydrogenated castor oil has many industrial applications.

What Is It?
PEG-30 Castor Oil, PEG-33 Castor Oil, PEG-35 Castor Oil, PEG-36 Castor Oil and PEG-40 Castor Oil are polyethylene glycol derivatives of castor oil. PEG-30 Hydrogenated Castor Oil and PEG-40 Hydrogenated Castor Oil are polyethylene glycol derivatives of hydrogenated castor oil. PEG-36 Castor Oil is a light yellow and slightly viscous liquid with a mild fatty odor. PEG-40 Castor Oil is an amber-colored liquid. PEG Castor Oils and PEG Hydrogenated Castor Oils are used in the formulation of a wide variety of cosmetics and personal care products.

Why is it used in cosmetics and personal care products?
PEG Castor Oils and PEG Hydrogenated Castor Oils help to form emulsions by reducing the surface tension of the substances to be emulsified. They also help other ingredients to dissolve in a solvent in which they would not normally dissolve.

Benefits of Hydrogenated castor oil
Hydrogenated castor oil is said to provide the following benefits for the face and skin:

Face
Acne: The antimicrobial and anti-inflammatory properties of Hydrogenated castor oil make it useful in reducing acne. Ricinoleic acid can inhibit growth in the bacteria that cause acne.
Texture: Hydrogenated castor oil is also rich in other fatty acids. These can enhance smoothness and softness when applied to facial skin.
Complexion: The fatty acids in Hydrogenated castor oil can also promote the growth of healthy skin tissue, making it helpful in restoring uneven skin tones.
Sensitive skin: Hydrogenated castor oil has a low comedogenic score. This means it is unlikely to clog pores in the skin and reduces the risk of developing blackheads, making it appropriate for use on sensitive skin.
Inexpensive: Skincare products, and in particular facial creams and oils, can be very expensive. Hydrogenated castor oil is relatively low-cost and shares many similar properties, such as promoting a healthful complexion or moisture in the skin.

Skin
Anti-inflammatory: Both Hydrogenated castor oil and ricinoleic acid have demonstrated anti-inflammatory properties. This makes them useful for treating irritated skin.
Antimicrobial: It may also protect the skin from bacterial infections by keeping out microbes that can cause disease.
Moisturizing: Hydrogenated castor oil contains triglycerides. These can help maintain moisture in the skin, making it a useful treatment for dry skin.
Hydration: Hydrogenated castor oil may have humectant properties, which means that it can draw moisture from the air into the skin, keeping the skin hydrated.
Cleansing: The triglycerides found in Hydrogenated castor oil are also helpful in removing dirt from the skin.
While Hydrogenated castor oil contains many chemicals linked to improved skin health, there has been limited research into the dermatological benefits of Hydrogenated castor oil. It might be more effectively put to use alongside other treatments.

Hydrogenated castor oil, also known as castor wax, is a hardened vegetable wax produced from pure Hydrogenated castor oil through the chemical process of hydrogenation. When hydrogen is introduced to pure Hydrogenated castor oil in the presence of a nickel catalyst, the resulting product becomes waxy, highly viscous, and more saturated.Hydrogenated castor oil is an ingredient prevalently found in many cosmetics, varnishes, and polishes. You most likely use it on a daily basis. Unlike pure Hydrogenated castor oil, which is said to have a slightly offensive smell, it is completely odorless. Hydrogenated castor oil is also insoluble in water.But why hydrogenate Hydrogenated castor oil when the pure oil works so well for so many different applications? What is the purpose of hydrogenating Hydrogenated castor oil, exactly? ydrogenated Hydrogenated castor oil, also known as castor wax, is derived from castor beans (Ricinus communis), which is typically a liquid at room temperature, that has been processed by adding hydrogen to make it more stable and raises its melting point so that it is a solid at room temperature. It is odorless and insoluble in water. Historically, ancient Egyptians used Hydrogenated castor oil as fuel for their lamps. Hydrogenated castor oil has also been used as a lubricant in machine and aircraft engines, and is added to certain paints, dyes and varnishes as well. 
Ingestion of pure Hydrogenated castor oil works as a laxative to treat constipation. Hydrogenated castor oil is a hard brittle, high melting point waxy substance with faint characteristic of fatty wax odor and is tasteless. It is compatible with beeswax, carnauba and candelilla wax. It is relatively insoluble in most organic solvents though it will dissolve in a number of solvents and oils at an elevated temperature but on cooling will form gels or a paste like mass. It forms a smooth, stable anionic emulsion with emulsifiers and triethanolamine stearate. It can also be emulsified with a cationic emulsifying agent, making emulsions that are also stable. It is mainly used in plastics, textiles, lubricants etc.As a pharmaceutical grade inactive ingredient, Hydrogenated castor oil is used to emulsify and solubilize oils and other water-insoluble substances. 

Hydrogenated castor oil, also known as castor wax, is derived from castor beans (Ricinus communis), which is typically a liquid at room temperature, that has been processed by adding hydrogen to make it more stable and raises its melting point so that it is a solid at room temperature. It is odorless and insoluble in water.
Hydrogenated castor oil is a hard, waxy substance with a unique structure. It works with the other oils and waxes in the antiperspirant base to give the stick a firm but spreadable consistency. In all cases, because Hydrogenated castor oil is insoluble in water, it is not readily washed away. 
Hydrogenated castor oil has a long history of safe use in personal care products.
PEG 40 Hydrogenated castor oil is the Polyethylene Glycol derivatives of Hydrogenated castor oil, and it functions as a surfactant, a solubilizer, an emulsifier, an emollient, a cleansing agent, and a fragrance ingredient when added to cosmetics or personal care product formulations. 
Hydrogenated castor oil is soluble in both water and oil and is traditionally used to emulsify and solubilize oil-in-water formulations. Its foam-enhancing properties make it ideal for use in liquid cleansers, and its soothing and softening emollient quality makes it a popular addition to formulations for moisturizers and hair care cosmetics. As a surfactant, PEG 40 Hydrogenated castor oil helps to decrease the surface tension between multiple liquids or between liquids and solids. Furthermore, it helps to remove the grease from oils and causes them to become suspended in the liquid. This makes it easier for them to be washed away and lends this ingredient popularity in facial and body cleansers. As an occlusive agent, PEG 40 Hydrogenated castor oil creates a protective hydrating layer on the skin's surface, acting as a barrier against the loss of natural moisture.
Hydrogenated castor oil to cosmetics formulations, it can be blended in its cold state directly into the oil phase at a suggested ratio of 3:1 (PEG 40 Hydrogenated castor oil to oil). Next, this can be added to the water phase. If the formula is cloudy, the amount of PEG 40 Hydrogenated castor oil may be increased for enhanced transparency.

A brand name product that contains Hydrogenated castor oil is Cremophor and it contains a range of non-ionic polyethoxylated detergents. It was originally developed for use as solubilizers and emulsifiers. This research grade product is intended for use in R&D and development only. Hydrogenated castor oil (castor wax) is also used an extended release agent; stiffening agent; tablet and capsule lubricant. Hydrogenated castor oil has been used as a stimulant laxative to relieve occasional constipation, but it is rarely used today due to gentler and safer alternatives.
The purpose of the hydrogenation process is to improve Hydrogenated castor oil's melting point, texture, odor, and shelf-life.Once hydrogenated, the resulting Hydrogenated castor oil product is comprised of hard, brittle flakes. Hydrogenated castor oil is considered an organic ingredient, as well as a vegan one, as it is vegetable-derived.One application of Hydrogenated castor oil is to improve certain cosmetic products. You can add the flakes to cosmetic formulations until thoroughly melted. In this capacity, Hydrogenated castor oil acts as an emollient and a thickener; increasing the viscosity of creams, ointments, and lotions when their composition is too runny. Hydrogenated castor oil also stabilizes cosmetics that come in stick-form (like lipstick) and increases these products' melting points, making for a more stable product. In part thanks to Hydrogenated castor oil, it's not the end of the world if we leave a tube of red lipstick in a hot car! Hydrogenated castor oil means our lipsticks maintain a solid structure even when they're pushed to the limit, and our deodorant doesn't crumble as we apply it.Hydrogenated castor oil is a hard, waxy substance with a unique structure. It works with the other oils and waxes in the antiperspirant base to give the stick a firm but spreadable consistency. In the baby diaper cream and lotion it provides a protective barrier of the lotion/cream on the skin. In all cases, because Hydrogenated castor oil is insoluble in water, it is not readily washed away.
Hydrogenated castor oil is especially present in these types of products when something requires resistance to moisture and oils, such as in polishes, varnishes, and paints.

Hydrogenated castor oil Raw Material without the medical advice of a physician. This product should always be stored in an area that is inaccessible to children, especially those under the age of 7.
Hydrogenated castor oil Raw Material in 1 tsp of a preferred Carrier Oil and applying a dime-size amount of this blend to a small area of skin that is not sensitive. PEG 40 Hydrogenated castor oil must never be used near the inner nose and ears or on any other particularly sensitive areas of skin. Potential side effects of PEG 40 Hydrogenated castor oil include the itching,

PEG-30 Hydrogenated castor oil, PEG-33 Hydrogenated castor oil, PEG-35 Hydrogenated castor oil, PEG-36 Hydrogenated castor oil and PEG-40 Hydrogenated castor oil are polyethylene glycol derivatives of Hydrogenated castor oil. PEG-30 Hydrogenated castor oil and PEG-40 Hydrogenated castor oil are polyethylene glycol derivatives of Hydrogenated castor oil. PEG-36 Hydrogenated castor oil is a light yellow and slightly viscous liquid with a mild fatty odor. PEG-40 Hydrogenated castor oil is an amber-colored liquid. PEG Hydrogenated castor oils and PEG Hydrogenated castor oils are used in the formulation of a wide variety of cosmetics and personal care products.
Hydrogenated castor oil is the polyethylene glycol derivatives of Hydrogenated castor oil, and is an amber colored, slightly viscous liquid that has a naturally mildly fatty odor. It is used in cosmetics and beauty products as an emulsifier, surfactant, and fragrance ingredient, according to research. Accordingly, Hydrogenated castor oil is principally 12-hydroxystearic triglyceride.
Hydrogenated castor oil (HCO) or castor wax is used in capacitors, coatings and greases, cosmetics, electrical carbon paper, lubrication, polishes, and where resistance to moisture, oils and other petrochemical products is required.

USES & APPLICATIONS
HCO is an extremely versatile oleochemical that has a number of industrial and manufacturing applications:CASE: Because of its excellent resistance to moisture, Hydrogenated castor oil works extremely well as a viscosity modifier, and it also provides significant improvement in grease and oil resistance.Plastics: Hydrogenated castor oil performs the role of a lubricant and release agent for PVC and improves processing, dispersion and grease resistance of sheeted polyethylene. It is also useful in the preparation of various polyurethane coating formulas.Personal Care: There are multiple Hydrogenated castor oil uses in the manufacturing of personal care products, particularly as an emollient and thickening agent in ointments and deodorants, as well as hair care products and certain cosmetics.Waxes: Hydrogenated Caster Oil works as a binding agent in synthetic and petroleum waxes, as it makes the wax harder and more resistant to crumbling.Soaps and Detergents: Hydrogenated castor oil is sometimes used as an emulsifying agent in liquid soaps and detergents to enhance the stability of the liquid formula.Textiles: HCO makes an effective processing agent in various textile manufacturing applications. 

What does it do?
Hydrogenated castor oil is a hard, waxy substance with a unique structure. It works with the other oils and waxes in the antiperspirant base to give the stick a firm but spreadable consistency. In all cases, because Hydrogenated castor oil is insoluble in water, it is not readily washed away.
In monolithic tablets, the core is either prepared by direct compression or by wet granulation followed by coating the core with water impermeable materials on all the faces except the face which is in contact with the mucosa. Water-impermeable materials include Teflon, ethyl cellulose, cellophane, Hydrogenated castor oil, and so on. Such a system begins unidirectional drug flow toward the mucosa and avoids drug loss [163].
The results of Kurihara et al. (1996) indicate that Hydrogenated castor oil (HCO)-60 emulsions, when compared with conventional lecithin-stabilized emulsions, are more stable to LPL and show low uptake by RES organs, long circulations in the plasma and high distribution in tumors. Lin et al. (1992) confirmed that Hydrogenated castor oil-60 is a good emulsifier for the preparation of NE with better stability and prolonged and selective delivery properties. Thus, these sterically stabilized NEs could show potential as effective carriers for highly lipophilic antitumor agents to enhance the drug delivery in tumors. This was confirmed by Sakaeda et al. (1994) who found that the rate of selective delivery of Sudan II to liver, lungs, and spleen could be suppressed by using Hydrogenated castor oil-60-based NE. Conversely, the use of saturated MCT in NE was the most effective way to increase blood concentration of Sudan II, resulting in higher distribution to liver, lungs, spleen, and brain (Sakaeda and Hirano, 1995). Furthermore, an o/w-type NE containing Hydrogenated castor oil-60 was shown to be superior in the selective distribution of adriamycin-HCl to the liver and in decreasing concentration in heart and kidney (Yamaguchi et al., 1995). Again, Ueda et al. (2003) reported the effect of using a series of Hydrogenated castor oils having different oxyethylene numbers such as Hydrogenated castor oil10, Hydrogenated castor oil 20, Hydrogenated castor oil 30, Hydrogenated castor oil 60, and Hydrogenated castor oil 100 on the pharmacokinetics of menatetrenone (vitamin K2) incorporated in SO (SO)–based NE in rats. Plasma half-life of menatetrenone after administration as the NE prepared by Hydrogenated castor oil with 10 oxyethylene units (SO/Hydrogenated castor oil 10) was similar to that after the administration as SO/egg yolk phosphatides (SO/EYP), but was shorter than that as the NEs prepared by Hydrogenated castor oils with >20 oxyethylene units (SO/Hydrogenated castor oil 20, SO/Hydrogenated castor oil 30, SO/Hydrogenated castor oil 60, and SO/Hydrogenated castor oil 100). These findings clearly demonstrate that 20 oxyethylene units in Hydrogenated castor oils are the minimum requirement for the prolongation of the plasma circulation time of the incorporated drug in SO/Hydrogenated castor oils NEs. The earlier described studies suggest the involvement of oil or structured lipids in the enhancement of systemic circulation of the NE.

Hydrogenated castor oil is a multi-purpose vegetable oil that people have used for thousands of years.
It’s made by extracting oil from the seeds of the Ricinus communis plant.
These seeds, which are known as castor beans, contain a toxic enzyme called ricin. However, the heating process that Hydrogenated castor oil undergoes deactivates it, allowing the oil to be used safely.
Hydrogenated castor oil has a number of medicinal, industrial and pharmaceutical uses.
It’s commonly used as an additive in foods, medications and skin care products, as well as an industrial lubricant and biodiesel fuel component.
In ancient Egypt, Hydrogenated castor oil was burned as fuel in lamps, used as a natural remedy to treat ailments like eye irritation and even given to pregnant women to stimulate labor.
Today, Hydrogenated castor oil remains a popular natural treatment for common conditions like constipation and skin ailments and is commonly used in natural beauty products.

Here are 7 benefits and uses of Hydrogenated castor oil.
1. A Powerful Laxative
Perhaps one of the best-known medicinal uses for Hydrogenated castor oil is as a natural laxative.
It’s classified as a stimulant laxative, meaning that it increases the movement of the muscles that push material through the intestines, helping clear the bowels.
Stimulant laxatives act rapidly and are commonly used to relieve temporary constipation.
When consumed by mouth, Hydrogenated castor oil is broken down in the small intestine, releasing ricinoleic acid, the main fatty acid in Hydrogenated castor oil. The ricinoleic acid is then absorbed by the intestine, stimulating a strong laxative effect.
In fact, several studies have shown that Hydrogenated castor oil can relieve constipation.
For example, one study found that when elderly people took Hydrogenated castor oil, they experienced decreased symptoms of constipation, including less straining during defecation and lower reported feelings of incomplete bowel movements.
While Hydrogenated castor oil is considered safe in small doses, larger amounts can cause abdominal cramping, nausea, vomiting and diarrhea (4Trusted Source).
Although it can be used to relieve occasional constipation, Hydrogenated castor oil is not recommended as a treatment for long-term issues.
Hydrogenated castor oil can be used as a natural remedy for occasional constipation. However, it can cause side effects like cramping and diarrhea and should not be used to treat chronic constipation.

2. A Natural Moisturizer
Hydrogenated castor oil is rich in ricinoleic acid, a monounsaturated fatty acid.
These types of fats act as humectants and can be used to moisturize the skin.
Humectants retain moisture by preventing water loss through the outer layer of the skin.
Hydrogenated castor oil is often used in cosmetics to promote hydration and often added to products like lotions, makeup and cleansers.
You can also use this rich oil on its own as a natural alternative to store-bought moisturizers and lotions.
Many popular moisturizing products found in stores contain potentially harmful ingredients like preservatives, perfumes and dyes, which could irritate the skin and harm overall health.
Swapping out these products for Hydrogenated castor oil can help reduce your exposure to these additives.
Plus, Hydrogenated castor oil is inexpensive and can be used on the face and body.
Hydrogenated castor oil is thick, so it’s frequently mixed with other skin-friendly oils like almond, olive and coconut oil to make an ultra-hydrating moisturizer.
Though applying Hydrogenated castor oil to the skin is considered safe for most, it can cause an allergic reaction in some people (6Trusted Source).
Hydrogenated castor oil can help lock moisture in the skin. Though this natural alternative to store-bought products is considered safe for most, it can cause allergic reactions in some.

3. Promotes Wound Healing
Applying Hydrogenated castor oil to wounds creates a moist environment that promotes healing and prevents sores from drying out.
Venelex, a popular ointment used in clinical settings to treat wounds, contains a mixture of Hydrogenated castor oil and Peru balsam, a balm derived from the Myroxylon tree.
Hydrogenated castor oil stimulates tissue growth so that a barrier can be formed between the wound and the environment, decreasing the risk of infection.
It also reduces dryness and cornification, the buildup of dead skin cells that can delay wound healing (8).
Studies have found that ointments containing Hydrogenated castor oil may be especially helpful in healing pressure ulcers, a type wound that develops from prolonged pressure on the skin.
One study looked at the wound-healing effects of an ointment containing Hydrogenated castor oil in 861 nursing home residents with pressure ulcers.
Those whose wounds were treated with Hydrogenated castor oil experienced higher healing rates and shorter healing times than those treated with other methods (9Trusted Source).
Hydrogenated castor oil helps heal wounds by stimulating the growth of new tissue, reducing dryness and preventing the buildup of dead skin cells.

4. Impressive Anti-Inflammatory Effects
Ricinoleic acid, the main fatty acid found in Hydrogenated castor oil, has impressive anti-inflammatory properties.
Studies have shown that when Hydrogenated castor oil is applied topically, it reduces inflammation and relieves pain.
The pain-reducing and anti-inflammatory qualities of Hydrogenated castor oil may be particularly helpful to those with an inflammatory disease such as rheumatoid arthritis or psoriasis.
Animal and test-tube studies have found that ricinoleic acid reduces pain and swelling.
One study demonstrated that treatment with a gel containing ricinoleic acid led to a significant reduction in pain and inflammation when applied to the skin, compared to other treatment methods.
A test-tube component of the same study showed that ricinoleic acid helped reduce inflammation caused by human rheumatoid arthritis cells more than another treatment.
Aside from Hydrogenated castor oil’s potential to reduce inflammation, it may help relieve dry, irritated skin in those with psoriasis, thanks to its moisturizing properties.
Although these results are promising, more human studies are needed to determine the effects of Hydrogenated castor oil on inflammatory conditions.
Hydrogenated castor oil is high in ricinoleic acid, a fatty acid that has been shown to help reduce pain and inflammation in test-tube and animal studies.

5. Reduces Acne
Acne is a skin condition that can cause blackheads, pus-filled pimples and large, painful bumps on the face and body.
It’s most common in teens and young adults and can negatively impact self-esteem.
Hydrogenated castor oil has several qualities that may help reduce acne symptoms.
Inflammation is thought to be a factor in the development and severity of acne, so applying Hydrogenated castor oil to the skin may help reduce inflammation-related symptoms.
Acne is also associated with an imbalance of certain types of bacteria normally found on the skin, including Staphylococcus aureus.
Hydrogenated castor oil has antimicrobial properties that may help fight bacterial overgrowth when applied to the skin.
One test-tube study found that Hydrogenated castor oil extract showed considerable antibacterial power, inhibiting the growth of several bacteria, including Staphylococcus aureus.
Hydrogenated castor oil is also a natural moisturizer, so it may help soothe the inflamed and irritated skin typical in those with acne.
Hydrogenated castor oil helps fight inflammation, reduce bacteria and soothe irritated skin, all of which can be helpful for those looking for a natural acne remedy.

6. Fights Fungus
Candida albicans is a type of fungus that commonly causes dental issues like plaque overgrowth, gum infections and root canal infections.
Hydrogenated castor oil has antifungal properties and may help fight off Candida, keeping the mouth healthy.
One test-tube study found that Hydrogenated castor oil eliminated Candida albicans from contaminated human tooth roots.
Hydrogenated castor oil may also help treat denture-related stomatitis, a painful condition thought to be caused by Candida overgrowth. This is a common issue in elderly people who wear dentures.
A study in 30 elderly people with denture-related stomatitis showed that treatment with Hydrogenated castor oil led to improvements in the clinical signs of stomatitis, including inflammation (17Trusted Source).
Another study found that brushing with and soaking dentures in a solution containing Hydrogenated castor oil led to significant reductions in Candida in elderly people who wore dentures (18Trusted Source).
Several studies have shown that Hydrogenated castor oil may help fight fungal infections in the mouth caused by Candida albicans.

7. Keeps Your Hair and Scalp Healthy
Many people use Hydrogenated castor oil as a natural hair conditioner.
Dry or damaged hair can especially benefit from an intense moisturizer like Hydrogenated castor oil.
Applying fats like Hydrogenated castor oil to the hair on a regular basis helps lubricate the hair shaft, increasing flexibility and decreasing the chance of breakage.
Hydrogenated castor oil may benefit those who experience dandruff, a common scalp condition characterized by dry, flaky skin on the head.
Though there are many different causes of dandruff, it has been linked to seborrhoeic dermatitis, an inflammatory skin condition that causes red, scaly patches on the scalp.
Due to Hydrogenated castor oil’s ability to reduce inflammation, it may be an effective treatment for dandruff that is caused by seborrhoeic dermatitis.
Plus, applying Hydrogenated castor oil to the scalp will help moisturize dry, irritated skin and may help reduce flaking.
The moisturizing and anti-inflammatory properties of Hydrogenated castor oil make it an excellent option to keep hair soft and hydrated and help reduce dandruff symptoms.

Hydrogenated castor oil Precautions
Many people use Hydrogenated castor oil to treat a variety of issues, either by ingesting the oil or applying it to the skin.
Although Hydrogenated castor oil is generally considered safe, it can cause adverse reactions and unwanted side effects in some people.
Can induce labor: It’s used by medical professionals to induce birth. For this reason, women at all stages of pregnancy should avoid consuming Hydrogenated castor oil.
Can cause diarrhea: While it can be an effective way to alleviate constipation, you may get diarrhea if you take too much. Diarrhea can cause dehydration and electrolyte imbalances.
Can cause allergic reactions: It may cause an allergic reaction in some people when applied to the skin. First try applying a small amount to a tiny patch of skin to see how your body reacts.
Hydrogenated castor oil can cause side effects, such as allergic reactions and diarrhea, in some people. It can also induce labor, so pregnant women should avoid it.
The Bottom Line
People have used Hydrogenated castor oil for thousands of years as a powerful natural treatment for a variety of health issues.
It has been shown to help relieve constipation and moisturize dry skin, among many other uses.
If you are searching for an affordable, multi-purpose oil to keep in your medicine cabinet, Hydrogenated castor oil may be a good choice.

Dehydrated Hydrogenated castor oil is an unique drying oil, which imparts good flexibility, fine gloss, toughness, adhesion, chemical and water resistance to the dry paint film with non-yellowing properties. Hydrogenated castor oil is a very suitable and even better substitute for Linseed oil. Paints with Hydrogenated castor oil are super white and offer superior finish.
Dehydrated Hydrogenated castor oil is used as a primary binder for house paints, enamels, caulks, sealants and inks. In “cooked” varnishes it is combined with all the basic resins, rosins, rosin-esters, hydrocarbons and phenolics to produce clear varnishes and vehicles for pigmented coatings. Hydrogenated castor oil is also used in the manufacturing of lithographic inks, linoleum, putty and phenolic resins.
Hydrogenated castor oil is used with phenolics to obtain fast drying coatings with maximum alkali resistance as required in sanitary can lining, corrosion resistant coatings, traffic paints, varnishes, ink vehicles, wire enamels, aluminium paint appliance finishes and marine finishes.
Hydrogenated castor oil is also used to obtain fast kettling rate which gives lighter colour and lower acid varnishes.

Hydrogenated castor oil is a release and antisticking agent used in hard candy pro- duction. its concentration is not to exceed 500 ppm. it is used in vitamin and mineral tablets, and as a component of protective coatings.
Hydrogenated castor oil is a highly emollient carrier oil that penetrates the skin easily, leaving it soft and supple. It also serves to bind the different ingredients of a cosmetic formulation together. Hydrogenated castor oil is high in glycerin esters of ricinoleic acid (an unsaturated fatty acid). It is rarely, if ever, associated with irritation of the skin or allergic reactions. It is obtained through cold-pressing from seeds or beans of the Ricinus communis (Hydrogenated castor oil) plant. Impure Hydrogenated castor oil may cause irritation, as the seeds contain a toxic substance that is eliminated during processing. Its unpleasant odor makes it difficult to use in cosmetics.
PEG-30 Hydrogenated castor oil, -30 Hydrogenated castor oil (hydrogenated), -40 Hydrogenated castor oil, -40 Hydrogenated castor oil (hydrogenated) are emollients, detergents, emulsifiers, and oil-in-water solubilizers recommended for fragrance oils, and for other oils that may be difficult to solubilize. The -40 Hydrogenated castor oil version is a powerful solubilizer for solubilizing essential oils and perfumes in oil-in-water creams and lotions. It is similar to Peg-30 Hydrogenated castor oil but denser, being a soft paste rather than a liquid. The hydrogenated version is particularly used as a nonionic emulsifier for essential oils and perfumes.

Hydrogenated castor oil is widely used in cosmetics, food products, and pharmaceutical formulations. In pharmaceutical formulations, Hydrogenated castor oil is most commonly used in topical creams and ointments at concentrations of 5–12.5%. However, it is also used in oral tablet and capsule formulations, ophthalmic emulsions, and as a solvent in intramuscular injections.
Therapeutically, Hydrogenated castor oil has been administered orally for its laxative action, but such use is now obsolete.
Hydrogenated castor oil is used in cosmetics and foods and orally, parenterally, and topically in pharmaceutical formulations. It is generally regarded as a relatively nontoxic and nonirritant material when used as an excipient.
Hydrogenated castor oil has been used therapeutically as a laxative and oral administration of large quantities may cause nausea, vomiting, colic, and severe purgation. It should not be given when intestinal obstruction is present.
Although widely used in topical preparations, including ophthalmic formulations, Hydrogenated castor oil has been associated with some reports of allergic contact dermatitis, mainly to cosmetics such as lipsticks.
Hydrogenated castor oil is stable and does not turn rancid unless subjected to excessive heat. On heating at 3008℃ for several hours, Hydrogenated castor oil polymerizes and becomes soluble in mineral oil. When cooled to 08℃, it becomes more viscous.
Hydrogenated castor oil should be stored at a temperature not exceeding 258℃ in well-filled airtight containers protected from light.

Hydrogenated castor oil is a vegetable oil pressed from castor beans.[1] Hydrogenated castor oil is a colourless to very pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm3.[2] It includes a mixture of triglycerides in which approximately 90 percent of fatty acid chains are ricinoleates. Oleate and linoleates are the other significant components.
Hydrogenated castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold resistant plastics, waxes and polishes, nylon, pharmaceuticals and perfumes.

Traditional medicine
Advertisement of Hydrogenated castor oil as a medicine by Scott & Bowne Company, 19th century
Use of Hydrogenated castor oil as a laxative is attested to in the circa 1550 BC Ebers Papyrus,[11] and was in use several centuries earlier.[12] The United States Food and Drug Administration (FDA) has categorized Hydrogenated castor oil as "generally recognized as safe and effective" (GRASE) for over-the-counter use as a laxative with its major site of action the small intestine, where it is digested into ricinoleic acid.
Although used in traditional medicine to induce labor in pregnant women, there is insufficient evidence that Hydrogenated castor oil is effective to dilate the cervix or induce labor.
Hydrogenated castor oil, or a Hydrogenated castor oil derivative such as Kolliphor EL (polyethoxylated Hydrogenated castor oil, a nonionic surfactant), is an excipient added to prescription drugs, including:
Miconazole, an antifungal agent;
Paclitaxel, a mitotic inhibitor used in cancer chemotherapy;
Sandimmune (cyclosporine injection, USP), an immunosuppressant drug widely used in connection with organ transplant to reduce the activity of the patient's immune system;
Nelfinavir mesylate, an HIV protease inhibitor;
Tacrolimus, an immunosuppressive drug (contains HCO-60, polyoxyl 60 Hydrogenated castor oil);
Xenaderm ointment, a topical treatment for skin ulcers, is a combination of Balsam of Peru, Hydrogenated castor oil, and trypsin;
Aci-Jel (composed of ricinoleic acid from Hydrogenated castor oil, with acetic acid and oxyquinoline), used to maintain the acidity of the vagina;
Optive Plus (carboxymethylcellulose, Hydrogenated castor oil) and Refresh Ultra (glycerine, Hydrogenated castor oil), artificial tears to treat dry eye;
Hydrogenated castor oil is also one of the components of Vishnevsky liniment.

Alternative medicinal use
In naturopathy, Hydrogenated castor oil is promoted as a treatment for several human health conditions,[24] including cysts. According to the American Cancer Society, "available scientific evidence does not support claims that Hydrogenated castor oil on the skin cures cancer or any other disease.
Skin and hair care
Hydrogenated castor oil has been used in cosmetic products included in creams and as a moisturizer. Small amounts of Hydrogenated castor oil are frequently used in cold process soap to increase lathering in the finished bar. It also has been used to enhance hair conditioning in other products and for supposed anti-dandruff properties.

Coatings
Hydrogenated castor oil is used as a bio-based polyol in the polyurethane industry. The average functionality (number of hydroxyl groups per triglyceride molecule) of Hydrogenated castor oil is 2.7, so it is widely used as a rigid polyol and in coatings.[1] One particular use is in a polyurethane concrete where a castor-oil emulsion is reacted with an isocyanate (usually polymeric MDI methylene diphenyl diisocyanate) and a cement and construction aggregate. This is applied fairly thickly as a slurry which is self-levelling. This base is usually further coated with other systems to build a resilient floor.
It is not a drying oil, meaning that it has a low reactivity with air compared to oils such as linseed oil and tung oil. Dehydration of Hydrogenated castor oil yields linoleic acids, which do have drying properties.[1] In this process, the OH group on the ricinoleic acid along with a hydrogen from the next carbon atom are removed yielding a double bond which then has oxidative cross-linking properties yielding the drying oil.

Precursor to industrial chemicals
Hydrogenated castor oil can be broken down into other chemical compounds that have numerous applications. Transesterification followed by steam cracking gives undecylenic acid, a precursor to specialized polymer nylon 11, and heptanal, a component in fragrances. Breakdown of Hydrogenated castor oil in strong base gives 2-octanol, both a fragrance component and a specialized solvent, and the dicarboxylic acid sebacic acid. Hydrogenation of Hydrogenated castor oil saturates the alkenes, giving a waxy lubricant.[1] Hydrogenated castor oil may be epoxidized by reacting the OH groups with epichlorohydrin to make the triglycidyl ether of Hydrogenated castor oil which is useful in epoxy technology.[32] This is available commercially as Heloxy.
The production of lithium grease consumes a significant amount of Hydrogenated castor oil. Hydrogenation and saponification of Hydrogenated castor oil yields 12-hydroxystearic acid which is then reacted with lithium hydroxide or lithium carbonate to give high performance lubricant grease.
Since it has a relatively high dielectric constant (4.7), highly refined and dried Hydrogenated castor oil is sometimes used as a dielectric fluid within high performance high voltage capacitors.

Lubrication
Vegetable oils like Hydrogenated castor oil are typically unattractive alternatives to petroleum-derived lubricants because of their poor oxidative stability. Hydrogenated castor oil has better low-temperature viscosity properties and high-temperature lubrication than most vegetable oils, making it useful as a lubricant in jet, diesel, and racing engines.[37] The viscosity of Hydrogenated castor oil at 10 °C is 2,420 centipoise.[38] However, Hydrogenated castor oil tends to form gums in a short time, and therefore its usefulness is limited to engines that are regularly rebuilt, such as racing engines. The lubricant company Castrol took its name from Hydrogenated castor oil.
Hydrogenated castor oil has been suggested as a lubricant for bicycle pumps because it does not degrade natural rubber seals.

Early aviation and aeromodelling
World War I aviation rotary engines used Hydrogenated castor oil as a primary lubricant, mixed with the fuel
Hydrogenated castor oil was the preferred lubricant for rotary engines, such as the Gnome engine after that engine's widespread adoption for aviation in Europe in 1909. It was used almost universally in rotary engined Allied aircraft in World War I. Germany had to make do with inferior ersatz oil for its rotary engines, which resulted in poor reliability.
The methanol-fueled two-cycle glow plug engines used for aeromodelling, since their adoption by model airplane hobbyists in the 1940s, have used varying percentages of Hydrogenated castor oil as a lubricant. It is highly resistant to degradation when the engine has its fuel-air mixture leaned for maximum engine speed. Gummy residues can still be a problem for aeromodelling powerplants lubricated with Hydrogenated castor oil, however, usually requiring eventual replacement of ball bearings when the residue accumulates within the engine's bearing races. One British manufacturer of sleeve valved four-cycle model engines has stated the "varnish" created by using Hydrogenated castor oil in small percentages can improve the pneumatic seal of the sleeve valve, improving such an engine's performance over time.
Turkey red oil, also called sulphonated (or sulfated) Hydrogenated castor oil, is made by adding sulfuric acid to vegetable oils, most notably Hydrogenated castor oil.[43] It was the first synthetic detergent after ordinary soap. It is used in formulating lubricants, softeners, and dyeing assistants.[43]

Biodiesel
Hydrogenated castor oil, like currently less expensive vegetable oils, can be used as feedstock in the production of biodiesel. The resulting fuel is superior for cold winters, because of its exceptionally low cloud point and pour point.
Initiatives to grow more castor for energy production, in preference to other oil crops, are motivated by social considerations. Tropical subsistence farmers would gain a cash crop.

Punishment
Some parents punished children with a dose of Hydrogenated castor oil. Physicians recommended against the practice because they did not want medicines associated with punishment.
A heavy dose of Hydrogenated castor oil could be used as a humiliating punishment for adults. Colonial officials used it in the British Raj (India) to deal with recalcitrant servants. Belgian military officials prescribed heavy doses of Hydrogenated castor oil in Belgian Congo as a punishment for being too sick to work.
The most famous use as punishment came in Fascist Italy under Benito Mussolini. It was a favorite tool used by the Blackshirts to intimidate and humiliate their opponents. Political dissidents were force-fed large quantities of Hydrogenated castor oil by Fascist squads. This technique was said to have been originated by Gabriele D'Annunzio or Italo Balbo.[54] Victims of this treatment did sometimes die, as the dehydrating effects of the oil-induced diarrhea often complicated the recovery from the nightstick beating they also received along with the Hydrogenated castor oil; however, even those victims who survived had to bear the humiliation of the laxative effects resulting from excessive consumption of the oil.[55] It is believed that the Nazi SA used this torture method against German Jews shortly after the appointment of Adolf Hitler as Chancellor of Germany in 1933.[56]
It is said that Mussolini's power was backed by "the bludgeon and Hydrogenated castor oil".[55] In lesser quantities, Hydrogenated castor oil was also used as an instrument of intimidation, for example, to discourage civilians or soldiers who would call in sick either in the factory or in the military. It took decades after Mussolini's death before the myth of Hydrogenated castor oil as a panacea for a wide range of diseases and medical conditions was totally demystified, as it was also widely administered to pregnant women and elderly or mentally ill patients in hospitals in the false belief it had no negative side effects.
Today, the Italian terms manganello and olio di ricino, even used separately, still carry strong political connotations (especially the latter). These words are still used to satirize patronizing politicians, or the authors of disliked legislation. They should be used with caution in common conversation. The terms Usare l'olio di ricino, ("to use Hydrogenated castor oil") and usare il manganello ("to use the bludgeon") mean "to coerce or abuse", and can be misunderstood in the absence of proper context.
Also in Greece, during the 4th of August Regime, Hydrogenated castor oil was used as a form of punishment.

Safety
The castor seed contains ricin, a toxic lectin. Heating during the oil extraction process denatures and deactivates the lectin. However, harvesting castor beans may not be without risk.[58] The International Hydrogenated castor oil Association FAQ document states that castor beans contain an allergenic compound called CB1A. This chemical is described as being virtually non-toxic but has the capacity to sensitize people with hypersensitivity. The allergen may be neutralized by treatment with a variety of alkaline agents. The allergen is not present in the Hydrogenated castor oil itself. These health issues, in addition to concerns about the toxic byproduct (ricin) from Hydrogenated castor oil production, have encouraged the quest for alternative sources for hydroxy fatty acids. Alternatively, some researchers are trying to genetically modify the castor plant to prevent the synthesis of ricin. 
Since Hydrogenated castor oil is sometimes used to induce labor in full-term pregnancies (scientific evidence of its effectiveness is lacking, however), consuming Hydrogenated castor oil to treat constipation is not considered safe in pregnancies that are not at full term yet, as it may cause contractions of the womb.

Hydrogenated castor oil is a translucent liquid with a yellow tint. It is an active ingredient in a wide variety of household items, from cleaning products to paints.
It has also been used to treat a range of medical conditions, most notably digestive issues.
Hydrogenated castor oil is broken down into ricinoleic acid in the small intestine. This speeds up the process of digestion. Although the evidence is less conclusive, Hydrogenated castor oil has also demonstrated some potential benefits for the face and skin.
Hydrogenated castor oil and ricinoleic acid are thought to increase absorption in the skin and are sometimes used in the treatment of various skin conditions, including dermatosis, psoriasis, and acne. There are also anecdotal reports of Hydrogenated castor oil promoting hair growth, including eyelashes, though no scientific literature that supports this.
By serving as a source of ricinoleic acid and several other fatty acids, Hydrogenated castor oil has some properties that make it a useful skincare product, particularly for the face.
