Polyglutamic Acid With Cosmetic Grade

We feel proud to introduce ourselves as a well reputed Exporter, Manufacturer and Supplier Company of Polyglutamic Acid With Cosmetic Grade in Qufu, Shandong, China. 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 a nattoa , which is also called I -polyglutamic acid (I -PGA). The polymer is anisomorphism type of polypeptide biopolymers with glutamic acid as a structural unit andconnected by amide bond formed through I -aminoand I -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 of Bacillus subtilis. Its INCI name is Sodium Polyglutamate. PGA is consists of glutamic acid monomers crosslinked between I -amino and I -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.
