Best polyglutamic acid powder (γ-PGA) is a water-soluble, biodegradable, non-toxic biopolymer material produced by microbial fermentation. γ-PGA polyglutamic acid is a special anionic natural polymer, which is a homopolyamide composed of an amide bond between a-amine group and y-carboxyl group.

The molecular weight of polyglutamic acid ranges from 50,000 to 2 million daltons.

Polyglutamic Acid Origin

Natto is a traditional fermented soybean food commonly consumed by Japanese. After fermentation, natto contains richer vitamins (B2, B6, B12, E, K2) and easier-to-digest protein than soybeans themselves. In addition, natto also contains a variety of digestive enzymes and special polysaccharides (Levan), thrombolytic enzyme (Nattokinase), and γ-polyglutamic acid (γ-PGA). It has excellent effects on promoting physical health. In recent years, it has become quite popular to consume natto to improve physical health.

Polyglutamic acid powder is the main component of natto viscous colloid and has the effect of promoting mineral absorption. Polyglutamic Acid has already listed in health ingredients that promote mineral absorption by Japanese.

The special molecular structure of γ-PGA gives it extremely strong moisturizing ability. Adding γ-PGA to cosmetics or skin care products can effectively increase the skin’s moisturizing ability and promote skin health.

Polyglutamic Acid Properties and Structure

Biodegradable and Biocompatible: PGA is known for its excellent biocompatibility and biodegradability, making it suitable for various medical and cosmetic applications.

Water-Soluble: It has high water solubility and can form hydrogels, which are beneficial for moisture retention.

Plyglutamic Acid Features

Significantly reduces transepidermal water loss, promotes the production of natural skin moisturizing factors, and lowers water loss rate;

The hydrogel's network structure sustainably releases stored nutrients;

It can form protective film on the surface of the skin, and to reflect most ultraviolet radiation;

It can reach the basal layer of the skin and is significantly better than molecules with polysaccharide structure in transdermal absorption.
