Product Description

Polyglutamic acid is a safe and natural and biodegradable multifunctional biopolymer produced via fermentation of L-glutamic acid with Bacillus subtilis. It is a water-soluble homo-polyamide consisting of Dglutamic acid and L-glutamic acid monomers connected by amide linkages between α-amino and γ-carboxyl groups. Its molecular weight is usually between 100 – 1000 kDa. It is applicable to a wide range of products including home and personal care, food, healthcare, water treatment and agriculture. When applied in cosmetic products, a dosage of 0.05% - 1.00% is recommended. In the food industry, Polyglutamic acid can function as a thickener, stabilizer, texture enhancer, or nutrition supplement.

Product Function

Polyglutamic acid( γ- PGA), also known as natto bacterial gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. γ- PGA polyglutamic acid is a viscous substance, which was first found in "natto" - fermented beans. γ- PGA polyglutamic acid is a special anionic natural polymer α- Amino group( α Chemicalbook amino) and γ- Carboxyl group( γ- Homo polyamide formed by amide linkage between caboxyl) γ- The molecular weight of PGA varies from 50000 to 2 million Daltons. Its moisturizing and water locking effect is 500 times that of hyaluronic acid. It is mainly used to moisturize, whiten, inhibit bacteria and improve skin health.
