Ammonium lauryl Sulphate (ALS) is the common name for ammonium dodecyl Sulphate (CH3(CH2)10CH2OSO3NH4). The anion consists of a nonpolar hydrocarbon chain and a polar sulphate end group.
The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates dissolution of both polar and non-polar materials.
ALS is classified as a sulphate ester.
Ammonium Lauryl Sulphate is found primarily in shampoos and body-wash as a foaming agent.
Lauryl Sulphates are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.
Ammonium lauryl Sulphate appears as light yellow liquid.
May float or sink and mix with water.
Action in solution
Above the critical micelle concentration, the anions organize into a micelle, in which they form a sphere with the polar, hydrophilic heads of the sulphate portion on the outside (surface) of the sphere and the nonpolar, hydrophobic tails pointing inwards towards the center.
The water molecules around the micelle in turn arrange themselves around the polar heads, which disrupts their ability to hydrogen bond with other nearby water molecules.
The overall effect of these micelles is a reduction in surface tension of the solution, which affords a greater ability to penetrate or "wet out" various surfaces, including porous structures like cloth, fibers, and hair.
Accordingly, this structured solution allows the solution to more readily dissolve soils, greases, etc. in and on such substrates.
Lauryl sulphates however exhibit poor soil suspending capacity.
What is Ammonium Lauryl Sulphate?
Ammonium lauryl sulphate, also known as ALS is a commonly used fat based molecule.
What is Ammonium Lauryl Sulphate is usually made from coconut or palm kernel oil.
The fat molecules in the oil are broken down and then reacted to produce something called a ‘surfactant’ – a compound that is often used in detergents, emulsifiers (stabiliser), foaming agent and dispersant.
What is Ammonium Lauryl Sulphate is often found in hygiene products like cleansers, shampoos and soaps and is popular due to it wide variety of uses and its relatively cheap cost.
While related, ammonium lauryl sulphate is not the same as ammonium laureth sulphate (ALES) which works in a similar manner but has additional ‘ether’ groups in the fatty end of the molecule.
How does What is Ammonium work?
The key part of this molecule is the ‘lauryl sulphate’ section.
The lauryl sulphate part has one fatty end and one charged end which lets it work as an adapter between oil and water which would otherwise repel each other and refuse to mix.
In the same way that washing up liquid can help water wash grease off a frying pan, detergents in cleansers and soaps can remove make up and oily debris on the face by grabbing it with their fatty end and then getting pulled away by water grabbing their charged end.
In both shampoos and toothpaste, ALS can be responsible for the foaming and lather produced during use as it forms a thin film that traps air into bubbles.
What is Ammonium Lauryl Sulphate?
Sodium lauryl sulphate and Ammonium lauryl Sulphate are widely used surfactant in shampoos, bath products, hair colorings, facial makeup, deodorants, perfumes, and shaving preparations; however, they can also be found in other product formulations.
Why is Ammonium Lauryl Sulphate used in cosmetics and personal care products?
Sodium lauryl sulphate and Ammonium lauryl Sulphate are surfactant that help with the mixing of oil and water.
As such, they can clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away or suspend poorly soluble ingredients in water.
Safety
Ammonium lauryl Sulphate is an innocuous detergent.
A 1983 report by the Cosmetic Ingredient Review, shampoos containing up to 31% ALS registered 6 health complaints out of 6.8 million units sold.
These complaints included two of scalp itch, two allergic reactions, one hair damage and one complaint of eye irritation.
The CIR report concluded that both sodium and Ammonium lauryl Sulphate “appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin.
In products intended for prolonged use, concentrations should not exceed 1%.”
Environment
The HERA project also conducted an environmental review of alkyl sulphates that found all alkyl sulphates are readily biodegradable and standard wastewater treatment operations removed 96–99.96% of short-chain (12–14 carbons) alkyl sulphates.
Even in anaerobic conditions at least 80% of the original volume is biodegraded after 15 days with 90% degradation after 4 weeks.
Uses
Ammonium lauryl Sulphate is a surfactant with emulsifying capabilities.
given its detergent properties, at mild acidic pH levels it can be used as an anionic surfactant cleanser.
Ammonium Lauryl Sulphate is considered one of the most irritating surfactants, causing dryness and skin redness.
Today, it is either combined with anti-irritant ingredients to reduce sensitivity or replaced with a less irritating but similar surfactant, such as Ammonium Lauryl Sulphate.

Animals exposed to ALES may experience eye damage, depression, labored breathing, diarrhea, and severe skin irritation.
MORE INFORMATION
Ammonium Lauryl Sulphate is added to products as a foaming agent, and as a detergent.
Ammonium Lauryl Sulphate is used in many shampoos, toothpastes, and skin cleansers.
Ammonium Lauryl Sulphate can cause moderate to severe skin and eye irritation.
Ammonium Lauryl Sulphate can also be contaminated with 1,4-Dioxane a suspected carcinogen.
The severity of the irritation to increases directly with the concentration of Ammonium Lauryl Sulphate in a product.
When combined with other chemicals, Ammonium Lauryl Sulphate can create nitrosamines, which are a potent class of carcinogens.
Ammonium Lauryl Sulphate may also damage skin’s immune system by causing skin layers to separate, inflame and age.

Origin (s): Vegetable , Synthetic
INCI name: Ammonium lauryl Sulphate
N ° EINECS / ELINCS: 218-793-9
Classification: Sulphate , Anionic surfactant
Bio compatible (COSMOS standard)
Ammonium lauryl Sulphate or ALS is an anionic surfactant.
Ammonium lauryl Sulphate is therefore widely used in shower gels and shampoos.
Ammonium lauryl Sulphate seems to be a little less irritating than its fake brother SLS (Sodium Lauryl Sulphate).
Ammonium Lauryl Sulphate is authorized organically.
Ammonium lauryl Sulphate's functions (INCI)
Cleaning Agent: Helps keep a clean surface
Foaming Agent: Captures small bubbles of air or other gases in a small volume of liquid by changing the surface tension of the liquid
Surfactant: Reduces the surface tension of cosmetics and contributes to the uniform distribution of the product during its use
Action in solution
Ammonium lauryl Sulphate, like any other surfactant, makes a good base for cleansers because of the way it disrupts the hydrogen bonding in water.
Hydrogen bonding is the primary contributor to the high surface tension of water.
In solution, the lauryl sulphate anions and the ammonium cations separate.
The former align themselves into what is known as a micelle, in which the ions form a sphere, with the polar heads (the sulphate) on the surface of the sphere and the nonpolar hydrophobic tails pointing inwards towards the center.
The water molecules around the micelle arrange themselves around the polar heads, but this disrupts their hydrogen bonding with the water surrounding them.
The overall effect of having these micelles in an aqueous (water) environment is that the water becomes more able to penetrate things like cloth fibers or hair, and also becomes more readily available to solvate anything coming off the aforementioned substance.

Uses
Ammonium Lauryl Sulphate (ALS) is an anionic surfactant found primarily in shampoos and body-wash as a foaming agent
Characteristics
1. Rich and fine foam, biodegradable ability.
2. Low degreasing ability, low irritation to skin and hair.
3. Obviously improve the combability and smoothness of hair.
4. Its mild decontamination performance makes smoothness to skin, and compounded with ALES, the effect will enhance.
5. Not applicable in alkaline system.
INCI Name: Ammonium Lauryl Sulphate
CAS No.: 2235-54-3
Einecs No.: 218-793-9
Application
1. Especially suitable for the application in high grade shampoo, bubble bath, baby shampoo, hand washing, and other foaming washing products.
2. The recommended dosage is 5-30%.
Ammonium Lauryl Sulphate (ALS) is also important to consider that not all shampoos include the same proportion of sulphates in their composition, though the percentage does not always appear among the ingredients listed.
A good measure of their quantity is to study where they are positioned in the list of ingredients: the higher they show up, the more prominent they are in the product.
If you have curly hair, Ammonium Lauryl Sulphate (ALS) is important to try to keep it as hydrated as possible for glossy and well-defined locks.
Even so, it may not be the best idea to completely stay off sulphate-based shampoos, to achieve a good and deep cleaning of the scalp and hair.
Try to incorporate a shampoo containing Ammonium Lauryl Sulphate (ALS) into your haircare regime once or twice a month tops and stick to a sulphate-free shampoo for regular washing.
When deciding on whether to use a shampoo containing ALES or not – and, if so, how frequently – there are two pointers worth mentioning.
If you have dyed hair, you should try and avoid using shampoos containing sulphates, as it can wash the colour out.
The same is true for swimmers who frequent the beach regularly since the salt exposure will work cleansing enough. also makes our hair that much more brittle.
In the long term, it may not only affect our hair’s health but its colour, too.
In the most extreme cases (and, generally, mostly among men), it can lead to hair loss.
How & When to Use Ammonium Lauryl Sulphate (ALS)
If you have dry hair or sensitive skin prone to irritation, you should try to avoid shampoos that include the most aggressive types of sulphates.
These are (from most to least harmful): sodium lauryl sulphate (SLS), Ammonium Lauryl Sulphate (ALS), sodium laureth sulphate (SLES) and Ammonium Lauryl Sulphate (ALS) (ALES).
Even so, this last one is not as aggressive as its lauryl cousin and, when used moderately, shouldn’t have any adverse effect on your hair.
If you have naturally oily hair, you may find that you need a sulphate-based shampoo to clean your hair properly.
This may also apply to styling products such as hair gel or creams you use frequently.
Not all sulphates are as strong as Ammonium Lauryl Sulphate (ALS).
There are other sulphates, such as Sodium Coco Sulphate, Cocoamphoacetate and Sodium Cocoyl Glycinate, that are becoming more and more present in different shampoo brands and that are not as strong as Ammonium Lauryl Sulphate (ALS).
