Cosmetic Pure Pga Polyglutamic Acid

To cater the variegated demands of our precious clients, our organization known as a leading Exporter, Manufacturer and Supplier of Cosmetic Pure PGA Polyglutamic Acid 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.
