Polyglutamic acid is also known as natto gum and polyglutamic acid. It is a water-soluble, biodegradable, non-toxic, biopolymer prepared by microbial fermentation.
Its moisturizing and water-retaining effect is 500 times that of hyaluronic acid.Mainly used for moisturizing, whitening, antibacterial, and improving skin health.
The role of polyglutamic acid:
Gamma-PGA polyglutamic acid is a sticky substance that was first discovered in "natto", a fermented soybean. γ-PGA polyglutamic acid is a special anionic natural polymer, which is a homotype formed by amide linkage between α-amino group (α-amino) and γ-carboxyl group (γ-caboxyl) The molecular weight of homo-polyamide γ-PGA varies from 50,000 to 2 million Daltons. Its moisturizing and locking effect is 500 times that of hyaluronic acid.
The main effect of γ-PGA polyglutamic acid in cosmetics
1. Functional long-lasting moisturizing to help skin resist dry environment.
2. Increase the elasticity of the skin and enhance the smooth and tender touch of the skin.
3. Inhibit skin melanin production.
4. Maintain healthy skin pH.
5. Form a slow-release delivery system, so that the skin can absorb various skin nutrients in skin care products more efficiently.
6. γ-PGA polyglutamic acid and γ-PGAHydrogel increase the color fastness of dyed hair.
7. γ-PGA polyglutamic acid and γ-PGAHydrogel increase the strength of hair and reduce hair splits and breakage.
8. γ-PGA polyglutamic acid and γ-PGAHydrogel improve hair combability.
