Cosmetic Grade CAS 25513-46-6 PGA Gamma-Polyglutamic Acid

What is Polyglutamic Acid(PGA)? Polyglutamic Acid(PGA),  A natural high-molecular weight amino acid polymer (big molecule from repeated subunits) that is claimed to have awesome, better than IT-moisturizer hyaluronic acid, skin hydrating properties. It is a film-forming polymer that improves both the moisture binding and retention properties of the skin. Polyglutamic Acid (gamma-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. 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 food additives, cosmetic ingredients, and water treatment.
