Polyglutamic Acid – High-Purity Biopolymer

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.

⚙️ Production Method

Microbial Fermentation (Biotechnological Method)

1. Inoculation of Bacillus subtilis in a nutrient-rich medium.

2. Fermentation process under controlled temperature and pH conditions.

3. Extraction and purification of γ-PGA via precipitation and filtration.

4. Drying and micronization into fine powder or granules.

This method ensures natural origin, high purity, and biodegradability of the final product.
