Product Introduction

Poly glutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic, biopolymer prepared by microbial fermentation. γ-PGA polyglutamic acid is a sticky substance and was first discovered in "Natto"-fermented beans. γ-PGA polyglutamic acid is a special anionic natural polymer, which is composed of α-amino group (α-amino) and γ-carboxyl group (γ-caboxyl) through amide linkage. The molecular weight of homo-polyamide γ-PGA ranges from 50,000 to 2 million Daltons.


●Non-toxic to human body and environment, biodegradable, eco-friendly;

●Water soluble, can obtain tasteless clean transparent solution;

●It can be made into sodium, calcium, magnesium, hydrogen type.


★γ -PGA and its derivatives have molecular weights ranging from 50,000 to 2 million daltons, so they can be widely used in food industry, cosmetics, health care, water treatment, wastewater treatment, sanitary products, medical and hydrogel and other fields.

★Food Industry: As a thickener for food and beverage, to improve the taste of beverages, as a stabilizer added to ice cream;

★Water Treatment: An absorbent or chelating agent for heavy metals;

★Healthcare: It is beneficial to the calcium absorption of osteoporosis patients.


1. Long-lasting moisturizing

The aqueous solution of Poly glutamic acid is a colorless and odorless transparent colloid. Due to its special three-dimensional lattice structure, poly l glutamic acid has a strong 5000 times water absorption and moisturizing ability, plus its smooth skin feel and easy film formation. , Can significantly enhance the skin's moisturizing effect, reduce water loss, and promote skin to restore elasticity. Compared with hyaluronic acid, its moisturizing and water-retaining effect is more significant.

2. Whitening

Skin care products added with γ-PGA can synergize other whitening ingredients, significantly inhibit the production of melanin, and have the effect of whitening skin.

Sunscreen isolation: Due to the superior film-forming properties of γ-PGA, skin care products added with γ-PGA can form a breathable biological protective film on the surface of the skin, which can lock the skin moisture while resisting external invasion, blocking ultraviolet rays, and anti-fogging It exhibits excellent effects in haze and sunscreen products.

3. Anti-wrinkle and anti-aging

 Increase the content of natural moisturizing factors in the stratum corneum of the skin, promote the growth of fibroblasts in the deep layer of the skin, balance the pH of the skin, restore elasticity to the skin, and smooth the fine lines caused by lack of water. 

With its special molecular structure,poly glutamic acid powder has a strong moisturizing ability, which can effectively increase the skin's moisturizing ability and promote skin health. Its super moisturizing ability is better than hyaluronic acid (HA) and Collagen, making it a new generation of biological technology moisturizing ingredients.  As a whitening agent, it has long - lasting crease resistance. It is more advantageous than other polymer commodities.
