Description:

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. 

Function:

1.Active component for lasting moisturizing and resistance to dry conditions of human skin.

2.Increasing the elasticity of human skin and keeping it tight and smooth.

3.Inhibiting the formation of melanin remarkably.

4.Keeping pH balance of human skin.

5.Forming a slow-release delivery system and therefore improving the absorption capacity of   nutrients in cosmetics.

6.Enhancing color fastness after hair dying.

Application:

1.Food Industry:As thickener for foods & drinks, improves taste of drinks, stabilizer in ice creams, texture enhancer, binder, animal feed supplement, antifreezing agent or cryoprotectant, bitterness relieving agent, as an additive in preparation of starch foods (bakery & noodles) for avoiding staling, enhancing food texture and maintaining food shapes.

2. Water treatment:Heavy metal absorbent or chelating agent.

3.Waste water treatment:Biopolymer flocculant, a substitute for polyacrylamide.

4.Health Care:Facilitates calcium absorption in osteoporosis cases.

5. Medical treatment:Drug release carrier, a haemostatic agent, soft tissue augmentation,.

6. Cosmetics:As a humectant, moisturizer to improve skin care quality, as a whitening agent, has anti wrinkle property which gives long lasting effect.
