Use

Polyglutamic acid, also known as natto gum and polyglutamic acid, is a kind of water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. Its moisturizing and water locking effect is 500 times that of hyaluronic acid. It is mainly used for moisturizing, whitening, bacteriostasis and improving skin health. Polyglutamic acid (PGA) is a Homopolypeptide formed by the polymerization of glutamic acid monomer with amide bond. It is water-soluble, biodegradable and non-toxic. It can be widely used in food industry, cosmetics, health care, water treatment, wastewater treatment, sanitary products, medical treatment and other fields, such as thickening agent, cryoprotectant, slow-release agent, drug carrier, biological adhesive, humectant, biodegradable fiber, super absorbent resin, bioflocculant and heavy metal Ion absorbent, etc.
