Top Quality Polyglutamic acid Powder CAS 25513-46-6

Details:

Polyglutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. γ-PGA polyglutamic acid is a sticky substance that was first discovered in "natto" - fermented beans. γ-PGA polyglutamic acid is a special anionic natural polymer, which is the same type formed by amide linkage between α-amino group (α-amino) and γ-carboxyl group (γ-caboxyl). Polyamide (homo-polyamide) γ-PGA has a molecular weight ranging from 50,000 to 2 million Daltons. Its moisturizing and water-locking effect is 500 times that of hyaluronic acid. Mainly used for moisturizing, whitening, antibacterial, and improving skin health. Polyglutamic acid was first found in Japanese natto food (fermented small soybeans) in the high-viscosity drawing. It is abbreviated as γ-PGA in China. Biopolymerization through liquid fermentation to produce decomposable high-molecular amino acid polymers. characteristic

The main role of polyglutamic acid in cosmetics and skin care products is as a moisturizer and skin conditioning agent. The risk factor is 1, which is relatively safe and can be used with confidence. It generally has no effect on pregnant women. Polyglutamic acid is not acne-causing. Polyglutamic acid has a good promotion of the activity of fibroblasts, etc., and has skin revitalizing effect, and can be used in anti-aging and anti-wrinkle cosmetics; the promotion of fibroblast activity by polyglutamic acid with larger molecular weight is not as good as that of small molecular weight, but It is superior to small molecular weight products in terms of stable foam, moisturizing ability, and adsorption on hair. It is used in hair water to resist static electricity and make hair soft. Polyglutamic acid has the effect of whitening skin.
