With multiple biological functions, γ-polyglutamic acid presents great potential for cosmetic products development. The vigorous development of the medical aesthetics market has led to a growing demand for high-quality γ-polyglutamic acid products. Creative Biolabs is always confident in offering the most reliable and highest quality research-grade γ-polyglutamic acid to help our clients break down barriers.

Introduction of γ-Polyglutamic Acid

First discovered as the major component in the capsule of Bacillus anthracis, γ-polyglutamic acid is a natural biopolymer composed of single glutamic acid. In general, γ-polyglutamic acid includes γ-(D)-polyglutamic acid, γ-(L)-polyglutamic acid, and γ-(D,L)-polyglutamic acid. As a polypeptide, γ-polyglutamic acid has a series of properties of interest to researchers, including water-solubility, edibility, and environmental friendliness. In the past decades, γ-polyglutamic acid presents potential applications in multiple fields, such as food, agriculture, biodegradable plastics, cosmetics, etc.

For skincare use, γ-polyglutamic acid helps to absorb moisture from the air into the skin to keep it hydrated and healthy, just like like hyaluronic acid and glycerin. What’s more, the chemistry of γ-polyglutamic acid allows it to be homogeneously miscible and chemically stable in a matrix of ingredients typically used in facial creams.

By irradiating polyglutamic acid with gamma rays, a γ-polyglutamic acid hydrogel can be formed, and the physicochemical properties of the hydrogel allow it to absorb 5,000 times its weight in water, so hydrogels have the potential to replace glycerin in cosmetic formulations. In addition, γ-polyglutamic acid can be used as an additive to increase hair strength and protect hair from damage caused by bleaching.

Benefits of γ-Polyglutamic Acid in Cosmetics

Similar to hyaluronic acid and soluble collagen, γ-polyglutamic acid is an excellent hydrophilic humectant capable of forming a smooth, elastic film on the skin, thereby improving sensory perception, protecting the outer layers of the skin, and increasing the production of natural moisturizing factors. Studies have shown that cosmetic products containing γ-polyglutamic acid can provide energy to cells, stimulate lipid production, and strengthen the skin's supportive structure. In addition, it is non-toxic to the human body so that presents great potential for the discovery of cosmetic products.
