Polyglutamic acid (γ-PGA), also known as natto gum, polyglutamic acid, is a water-soluble, biodegradable, non-toxic, biopolymer produced by microbial fermentation. γ-PGA polyglutamic acid is a viscous substance that was first discovered in the "natto", fermented bean. γ-PGA polyglutamic acid is a special anionic natural polymer composed of amide linkage between α-amino group (α-amino) and γ-carboxyl group (γ-caboxyl). The molecular weight of homo-polyamide γ-PGA ranges from 50,000 to 2 million Daltons. Its moisturizing and water-blocking effect is 500 times that of hyaluronic acid.
