Polyglutamic Acid (γ-PGA) is a naturally occurring polymer of glutamic acid known for its exceptional water-binding capacity—holding up to 5,000 times its weight in water. Extracted primarily from Bacillus subtilis via microbial fermentation, it is a safe, non-toxic, and eco-friendly compound used across cosmetics, agriculture, biomedical, and food applications.
Cavin Resource offers industrial-grade and cosmetic-grade Polyglutamic Acid with >90% purity, available in powder or granular form. Our product is suitable for clients in formulation, R&D, or large-scale manufacturing, and we offer global shipping for B2B clients.
Microbial Fermentation (Biotechnological Method)
-
Inoculation of Bacillus subtilis in a nutrient-rich medium.
-
Fermentation process under controlled temperature and pH conditions.
-
