Polylysine as ingredient in skin care products and cosmetics


* A film former

* A preservative


Polylysine is a polypeptide of the essential amino acid, L-lysine, a popular food preservative. It is used in cosmetics and beauty products for two reasons: its ability to serve as a preservative, as well as its properties as a film former and hair conditioning agent. As a preservative, Polylysine can inhibit the growth of microorganisms, and specifically produce an antimicrobial effect against yeast, fungi, and bacteria, according to Wikipedia.

Polylysine may have anti-aging properties as well, due to its protein and amino acid content. According to an article on Amino Acids for Anti-Aging, “Amino acids … act by attaching to skin cells to fill in lines and make skin appear smoother, in addition to improving skin tone and color, providing exfoliation, reducing fine lines and wrinkles, and minimizing the appearance of photo damage.” Amino acids are powerful anti-aging ingredients because of their ability to communicate with cells, improving their ability to affect aging cells and repair them.

In a patent filed by L’Oreal, Polylysine is also noted as having the ability to “improve the surface state of keratin fibers,” a strong protein involved in hair and nail growth.

Safety Measures/Side Effects

According to the Cosmetics Database, Polylysine is a low hazard ingredient and considered 91% safe, with the only concern regarding a lack of data for its use in cosmetics. It has received the FDA’s GRAS (Generally Recognized as Safe) rating for inclusion in food products. No studies were found that reported negative side effects for Polylysine as an ingredient in cosmetic products.

The cosmetics are vulnerable to the pollution caused by microbe and easily go bad in storage and use process. Currently, the most effective way to avoid the bad effect on Human Skin caused by the alterative cosmetics and deterioration and mustiness of other products is to add Preservatives.

Ε-PL can effectively inhibit the growth of undesirable microorganisms in cosmetic and it is efficient and safe preservative commonly used in cosmetics.

Due to its extensive bactericidal performance, ε-PL has a wide range of applications in cosmetic and its application range will further expand because of its safety. Currently, our products are used in cosmetic companies in Korea, Italy and USA with remarkable effect. The Korea Company tested our products and the result of bacteriostatic effect is as follows:
