Cetpro PGA-S MMW

Gamma-Polyglutamic Acid (γ-PGA) is a natural, multi-functional, biodegradable biopolymer produced from L-glutamic acid through a fermentation process with a Bacillus subtilis. PGA is a water-soluble homo-polyamide consisting of D-glutamic acid and L-glutamic acid monomers connected by amide linkages between α-amino and γ-carboxyl groups. It has a good water absorbability, a long-lasting moisturizing effect and inhibition on melanin biosynthesis.

γ-PGA is a major constituent of the Japanese food natto. It has a wide number of potential uses ranging from food, medicine and water treatment. When applied in cosmetic products, the moisturizing effect of γ-PGA is better than that of hyaluronic acid and collagen protein; it can supply moisture to help the skin against a dry environment for a long period of time, also can restore skin elasticity and smooth skin wrinkles

  • Improves skin elasticity
  • Promotes the skins natural moisturising properties
  • Maintains skin pH
  • Reduces transepidermal water loss
  • Excellent skin hydration
  • Can enhance the growth of fibroblasts, promote the synthesis of collagen protein
  • Has whitening effects
  • Penetrates better than HA
  • Can inhibit the activity of hyaluronidase, stabilise HA levels
