Synopsis: Polyglutamic acid（ γ- PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer prepared by microbial fermentation. γ- PGA polyglutamic acid is a viscous substance, which was first found in "natto" - fermented bean. γ- PGA polyglutamic acid is a special anionic natural polymer α- Amino group（ α amino) and γ- Carboxyl group（ γ- Homo polyamide (Homo polyamide) formed by amide linkage between caboxyl) γ- The molecular weight of PGA ranges from 50000 to 2 million daltons. Its moisturizing and water locking effect is 500 times that of hyaluronic acid. It is mainly used for moisturizing, whitening, bacteriostasis and improving skin health.
