γ-Ployglutamic Acid

  1. Water absorption:
   PGA is of mass side chain carboxyl group, forming intramolecular and intermolecular hydrogen bond, which contribute to its high water-absorption and moisture retention properties.
  1. Hydrolysis Porperty:
   Hydrolyzed to Glutamic acid,Non-toxic and harmless
  1. Biodegradable Property
Green Macromolecule,pollution-free to the environment Application: PGA Widely used in cosmetics, environment protection, food industry, pharmaceutical, agriculture and desertification control, and so on. PGA(Gamma Poly Glutamic Acid) cosmetic grade
