Poly Glutamic Acid is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. Poly Glutamic Acid is a sticky material first found in "natto", a fermented soybean.Poly Glutamic Acid is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.

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 consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.

Function:
1.Active component for lasting moisturizing and resistance to dry conditions of human skin.

2.Increasing the elasticity of human skin and keeping it tight and smooth.

3.Inhibiting the formation of melanin remarkably.

4.Keeping pH balance of human skin.

5.Forming a slow-release delivery system and therefore improving the absorption capacity of nutrients in cosmetics.

6.Enhancing color fastness after hair dying.
