Description of Ethylparaben
Ethylparaben is produced naturally and found in several fruits and insects, where it acts as an antimicrobial agent.
Ethylparaben is mainly used as antiseptics in cosmetics, food and medicine (E number E214).
Ethylparaben is also can be used as feed preservatives and antiseptic for bacteria.
Ethylparaben is readily absorbed from the gastrointestinal tract or through the skin.
Ethylparaben is hydrolyzed to p-hydroxybenzoic acid and rapidly excreted in urine without accumulating in the body.
Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), cosmetic products and ingredients, other than color additives, do not need FDA approval before they go on the market.
Broad concentration ranges reported in each product category in 1981 were < 0.1% and > 0.1% to 1%. Studies show the in vivo estrogenicity of MP and EP at human exposure levels, and indicate that populations exposed to large amounts of MP and EP may have a high burden of estrogenicity-related diseases.

What Are The Functions Of Ethylparaben?
Ethylparaben functions as a preservative in cosmetics and skincare products.
In most formulations, parabens are used at very low levels ranging from 0.01 to 0.3%.
The use of preservatives is necessary to prevent microbial contamination, as well as to prevent the product from degrading or going rancid.
Preservatives like ethylparaben are vital to the safety of a formulation.

Antimicrobial
Skincare are highly susceptible to microbial contamination and growth.
The most susceptible products are creams and lotions that are packaged in jars, opened frequently, and applied to the skin with the fingers.
Further, by limiting the growth of bacteria and fungi, preservatives like isobutylparaben help keep us safe from infection and other diseases.
It’s true that skin already acts as a barrier, but if contaminated creams are applied to the skin, an inflammatory response can be elicited, and lead to skin damage in the long term.
In addition, bacteria can easily invade our bodies if contaminated product is applied to broken skin, or if small amounts of contaminated lipstick or lip balm are accidentally ingested through the mouth.

Increased shelf-life
Parabens help to stabilize the formulation of a product, increasing its shelf-life.
Without preservatives, most skincare or cosmetic products would only last 2-4 weeks before going rancid.

Inexpensive
In many ways, the inclusion of such preservatives is indispensable in our day and age. We often take for granted how cheaply some skin care products can be purchased, and the fact that we don’t have to waste money throwing away too many expired products in the trash.
In many ways, this is achieved through the use of parabens and other preservatives.

Ethylparaben Description
Parabens are a group of controversial preservatives that include butylparaben, isobutylparaben, propylparaben, methylparaben, and ethylparaben.
All of these were at one time the most widely used group of preservatives used in cosmetics.
Parabens were so popular because of their gentle, non-sensitizing, and highly effective profile in comparison to other preservatives but also because they were derived naturally from plants, a rare phenomenon for a preservative.
Parabens are found in plants in the form of p-hydroxybenzoic acid (PHBA), a chemical that breaks down to become parabens for a plants own protection.
Over the past 10 years parabens have become criticized and condemned for use in cosmetics due to their alleged relation to health concerns affecting women and men.
The research about parabens is conflicting and polarizing. Some research indicates they are safe as used in cosmetics and are preferred over other preservatives to keep a formula stable.
These studies also showed parabens did not have any effect when compared to natural hormones in the body.

What Is Ethylparaben?
Ethylparaben is a preservative that is used in the formulation of cosmetics and personal care products in order to extend the shelf-life by preventing microbial contamination.
Ethylparaben is the ethyl ester of p-hydroxybenzoic acid.
Ethylparaben is a member of the class of compounds known as parabens. Other common parabens include methylparaben, butylparaben, isobutylparaben, and propylparaben.
Ethylparaben is used to extend the shelf-life of a product life by preventing microbial contamination.
Microbial contamination can occur from exposure to bacteria and molds in the air and general use of the product from your hands.
Preservatives like parabens are designed to reduce the likelihood that bacteria and molds can grow in your product.
This is important for ensuring the safety of a product.
At one time, parabens were the most widely used group of preservatives in cosmetic products.
The reason why parabens were so popular is due to their gentle, non-sensitizing, and highly effective profile in comparison to other preservatives.
However, more recently they have been the topic of some controversy over claims that they can disrupt your hormones.
While this claim isn’t backed by the research it has scarred the reputation of parabens.

An ethyl ester of p-hydroxybenzoic acid, ethylparaben is primarily used as an antifungal preservative in food and other applications.
Ethylparaben is also used extensively in the cosmetics industry as a preservative in everything from body lotion and skin cream to deodorant and antiperspirant.
Ethylparaben is also added to essential oils to provide additional stability, and it is rare to find cosmetics that do not contain some form of ethylparaben as a means of preserving their contents over time and preventing the growth of fungus and bacteria.
In terms of toxicity, there has been a considerable amount of debate in the cosmetics industry and the medical industry as to the carcinogenic nature of ethylparaben, though independent experts and the US FDA have both determined through extensive research that the levels of ethylparaben in cosmetics present an extremely low risk of being carcinogenic.
To date, no strong evidence has been found that demonstrates that ethylparaben causes cancer in human beings.

Uses & Benefits of Ethylparaben
Parabens have been safely used for almost 100 years as preservatives in the food, drug and personal care and cosmetic industries.
Parabens (including methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, and isobutylparaben) may be used in products such as makeup, moisturizers, and hair care and shaving products.
Contrary to some reports, most major brands of deodorants and antiperspirants no longer contain parabens.

Preservatives like parabens may be used in cosmetics to protect against microbial (e.g., bacteria, fungus) growth, both to protect consumers and to maintain product integrity.
In the food industry, parabens have been used for more than 50 years as preservatives and anti-microbial agents. Some fruits, such as blueberries, contain parabens as a naturally occurring preservative.
Parabens are widely used in confectioneries, cereal-based snacks, dried meats, and much more.

Product description
Preservative for the cosmetic industry. It is a broad spectrum antimicrobial agent designed for preservation of a wide range of cosmetics, toiletries and topical pharmaceuticals.
Ethylparaben remains fully stable over a wide pH range from 4- 8.
In general the lower the pH of the formula-tion, the more active it is. That can result in a lower use concentration when the pH of the formulation is more acidic.

Applications
Ethyl 4-hydroxybenzoate (ethylparaben) was used to study the in-situderivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols and triclosan in water.
Ethylparaben is a novel sorbent for solid-phase extraction, was used to study its retention property. It has high extraction efficiency towards the compounds tested owing to the electrostatic interaction, hydrophobic interaction and hydrogen bonding.

What is Ethylparaben?
Ethylparaben is an ethyl ester of Para-hydroxy benzoic acid. It comes as small colorless crystals or powder.

Use & Benefits of Ethylparaben:
Parabens are the class of drug, used for many years in cosmetics as a preservative.
Ethylparaben prevents the growth of bacteria and fungi.
Usually, when product encounters unfavorable conditions like humidity, temperature, and/or sunlight, there are chances product may get decompose or separated or fungi or bacteria can develop.
So, the preservatives are crucial for maintaining the product with the exact same quality throughout the shelf life.
In the lower dose, the parabens are considered safe to use and non-irritant.
Ethylparaben is used as a preservative in not only in cosmetics, adhesives, and pharmaceuticals.
