Polyglutamic Acid(¦Ã-PGA), also known as natto gum or polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer prepared by microbial fermentation.It is 500 times more effective than hyaluronic acid in hydrating and holding water.Mainly used for moisturizing, whitening, bacteriostasis and improving skin health.
Poly Glutamic Acid is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation.Poly Glutamic Acid (gamma-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. Poly Glutamic Acid is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of food, cosmetics, and water treatment.
