• Detailed Description:

  Cas No. :9057-02-7 Introduction
  
  Gamma-poly-glutamic acid (纬-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 伪-amino and 纬-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxic towards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
  
  Functions of PGA in cosmetics
  
  (1) Long-lasting moisturizing effect
  Possess extremely high moisturizing effect, better than Hyaluronic acid and Collagen.
  Provide long-lasting humectation effect, especially under dry place.
  Restore skin elasticity, smooth the wrinkles
  (2) Increasing nutriments absorption of the skin
  Release and supply nutriments gradually
  (3) Whitening the skin
  Inhibition on Melanin Biosynthesis
  (4) Enhance the skin health
  Facilitate the skin health condition by enhancing the growth of fibroblast cells.
  Effectively promote the N.M.F inside the skin.
  Balance the skin's pH value.
  Effectively protect skin against pathogenic microbial activity.
  (5) PGA is a special product with multiple functions toward skin and fully compatible with skin conditions.
  
  PGA is an effective ingredient with multiple functionalities toward skin, moisturizing, whitening, antibacterial, and improving skin health. It has anti-wrinkle effect and makes skin soft, tender and smooth. It brings skin cells regenerate; facilitates exfoliation of old keratin; clears stagnant melanin to create whiten and translucent skins free of dullness.
