CAS 25513-46-6 Polyglutamic acid, also known as natto bacteria gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic, biopolymer obtained by microbial fermentation.CAS 25513-46-6 Polyglutamic acid is a sticky substance first discovered in "natto" - fermented soybeans. Polyglutamic acid is a special anionic natural polymer, which is a homopolyamide (amide linkage) composed of α-amino group (α-amino) and Y-carboxyl group (Y-caboxyl) through amide linkage. The molecular weight of homo-polyamide) Y-PGA ranges from 50,000 to 2 million Daltons. Its moisturizing and locking effect is 500 times that of hyaluronic acid.Mainly used for moisturizing, whitening, antibacterial and promoting skin health. Polyglutamic acid was first found to exist in the highly viscous drawing of Japanese natto food (fermented small soybeans), and it is referred to as Y-PGA in China. Biopolymerization through liquid fermentation produces decomposable high-molecular amino acid polymers.
