What is Polyglutamic Acid?

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 of Bacillus 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 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.

Main 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.
