Product name: y-Polyglutamic Acid

Assay: HPLC 99%

CAS:25513-46-6

PGA has a molecular weights ranging from 50,000 to more than 2 million Daltons.

Application: Cometic or fertilizer filed

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.

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.

*Base Fertilizer:

Use it about 10kgs for a unit of area, then irrigate with clean water or muck water. Or irrigate amino acid together with water. Or fertilize with other compound fertilizers, broadcast application, hole application both are ok. It is applicable to all the crops.

*Foliar Fertilizer:

Dilute it by 800-1000 times and spray directly. Also, it can spray by mixed with trace element. Use 200-500g for a unit of area.

*Compound Fertilizer & 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.

Advatage For Fertilizer Gamma-PGA

1.Easy and high-efficacy absorption by plants.

2.Help the absorption and the translocation of the nutrients in cells.

3.Improves the immune system of the crops and increases their resistance against diseases, severe weather.

4.Simulates protein synthesis and gives strength to plants accelerating their growth.
