What is Grade Polyglutamic Acid:

 

PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation.

PGA is a sticky material first found in “natto”, a fermented soybean.

PGA is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.

Gamma-poly-glutamic acid (gamma-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 α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.

 

Major functions:


* Function-based long-lasting moisturizing that helps the skin resist dryness;
* Improvement of skin elasticity and smoothness;
* Inhibition of melanin;
* Maintenance of a healthy pH;
* Slow-release transport system that enables the skin to absorb all nutrients;  

*Molecular wt from 5kDa to 2000kDa, gel besides granular and powder are also available to meet your personalized demand.

*As a pioneer organization in National standard development for polyglutamic acid, we are always ready to share knowledge and experience, and work together with you to provide end customers with the best application experience.
