Best Price Poly Y Glutamic Acid
Product Description
PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation.Best Price Gamma Polyglutamic Acid
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.

Functions
1.Because the polymer has free a-carboxyl group, it has high hydration power. when Gamma PGA was applied to the skin, it would increase the amount of both pyrrolidonecarboxylic acid and lactic acid as the main components of Natural Moisture Factor (NMF). That is, Gamma PGA can bring out the moisture-holding ability from the inside of the skin.
2.Active component for lasting moisturizing and resistance to dry conditions of human skin
3.Increasing the elasticity of human skin and keeping it tight and smooth
4.Inhibiting the formation of melanin remarkably
5.Keeping pH balance of human skin
6.Forming a slow-release delivery system and therefore improving the absorption capacity of nutrients in cosmetics
7.Enhancing color fastness after hair dying
8.Reducing split ends and leaving hair soft, glossy and noticeably strong
Applications
1. Irrigation Fertilizer:
It can be added to compound fertilizer by rate of 5-8%, improve the nutrient content of compound fertilizer, increases crops’ direct absorption.
2. 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.
3. Medical treatment
Drug release carrier, a haemostatic agent, soft tissue augmentation.
4. Cosmetics Ingredient
As a humectant, moisturizer to improve skin care quality, as a whitening agent, has anti wrinkle property which gives long lasting effect.
