Cosmetic Grade Polyglutamic Acid Powder Cas 25513-46-6

Polyglutamic acid (γ - PGA), also known as natto gum or polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. Gamma PGA polyglutamic acid is a viscous substance first discovered in "natto" - fermented beans. Gamma PGA polyglutamic acid is a special anionic natural polymer composed of amide linkages between alpha amino and gamma carboxyl groups. The molecular weight of gamma PGA varies from 50000 to 2 million daltons. Its moisturizing and water locking effect is 500 times that of hyaluronic acid. Mainly used for moisturizing, whitening, antibacterial, and promoting skin health. Polyglutamic acid was first discovered to exist in the highly viscous fibers of Japanese natto food (fermented soybeans), abbreviated as γ - PGA in China. It is a biodegradable polymer of high molecular weight amino acids produced by the biological polymerization of natural natto bacteria and glutamic acid through liquid fermentation.
