Description
Polyglutamic Acid Powder Description
Polyglutamic Acid (PGA) which exists frequently in nature in the form of sodium polyglutamate, is usually a sticky anionic amino acid polymer. Initially, it was found in a traditional food ‘natto’, which is also called γ-Polyglutamic acid (γ-PGA). The polymer is an isomorphism type of polypeptide biopolymer with glutamic acid as a structural unit and connected by an amide bond.
Since each of the structural units of glutamic acid contains a plurality of hydrophilic groups, a large number 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 Hyafactor-PGA is produced by fermentation with a superior strain of Bacillus subtilis. Its INCI name is Sodium Polyglutamate.
