Poly Glutamic Acid PGA Cosmetic Grade

Introduction
Polyglutamic acid(PGA)which exists frequently innature in the form of sodium polyglutamate, is usually a sticky anionic amino acids polymer. Initially, it was found in a traditional food natto, which is also called γ-polyglutamic acid (γ-PGA). The polymer is anisomorphism type of polypeptide biopolymers with glutamic acid as a structural unit andconnected by amide bond formed through α-aminoand γ-carboxyl group. Since each of the structural unit of glutamic acid contains a plurality of hydrophilic groups, a large amount of hydrogen bonds can be formed inside or between the polymer chains, so PGA can effectively capture and retain moisture, enhance skin elasticity, and be regarded as a good natural moisturizing ingredient widely used in personal care products. Our PGA is produced by fermentation with a superior strain ofBacillus subtilis. Its INCI name is Sodium Polyglutamate. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between **0~***0 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.
