γ-Polyglutamic acid, also known as (γ-PGA, γ-polyglutamic acid), CAS NO: [ 25513-46-6 ] It is a water-soluble, biodegradable, non-toxic, produced by microbial fermentation of biopolymers. Gamma-PGA polyglutamic acid (gamma-polyglutamic acid) is a sticky substance first discovered in "natto" - fermented soybeans. γ-PGA polyglutamic acid (γ-polyglutamic acid) is a special anionic natural polymer, which is formed by an amide bond between α-amino (α-amino) and γ-carboxyl (γ-caboxyl) groups. Homo-polyamide γ-PGAs formed by amide linkages have molecular weights ranging from 50,000 to 2 million Daltons.

Characteristic
Non-toxic to humans and the environment
Biodegradable and eco-friendly
Water-soluble, resulting in an odorless, clean and transparent solution
Easy-to-crosslink to form hydrogels with superior performance at a later stage
Can be made into sodium, calcium, magnesium, hydrogen type.

Application field
The molecular weight of γ-polyglutamic acid (γ-PGA) (γ-polyglutamic acid) and its derivatives varies from 50,000 to 2 million Daltons, so they can be widely used in the food industry, Cosmetics, health care, water treatment, wastewater treatment, hygiene products, medical treatment and hydrogel fields
Food industry - as a thickener for food and beverages, to improve the taste of beverages, as a stabilizer in ice cream, as a texture enhancer, as a binder, as an additive for animal feed, as an antifreeze or as a protective agent, to reduce bitterness It is used as an additive in starchy foods (bread & noodles) to avoid aging, improve the texture of the food and maintain the shape of the food.
 
· Water treatment - absorbent or chelating agent for heavy metals.
·Wastewater treatment - biopolymer flocculant, can replace polyacrylamide.
·Health care - It is beneficial to the absorption of calcium by osteoporosis.
·Sanitary products - used as absorbent in baby diapers, feminine sanitary napkins, etc.
·Pharmaceuticals - drug release carriers, hemostatic agents, soft tissue fillers.
·Cosmetics - As a moisturizer to improve skin care quality, as a brightener with long lasting anti-wrinkle properties.
Advantages over other polymer commodities:
· γ-Polyglutamic acid (γ-PGA) (γ-polyglutamic acid) is a high-end product that is non-toxic, biodegradable and degradable, and has nutrients for the skin.
· Completely suitable for all skin conditions and provides long-lasting moisturizing benefits superior to HA (hyaluronic acid) and collagen
• Only very low concentrations are required, thus reducing costs.
· γ-PGA derivatives have good strength, transparency and elasticity.
Gamma-polyglutamic acid (γ-polyglutamic acid) (γ-PGA) is used in skin care products, shampoos, hair creams, shaving creams and lipsticks.
