γ-Polyglutamic Acid

Humectant

γ-Polyglutamic acid (PGA) was first discovered in fermented soybeans "natto" and is a viscous substance. It is a naturally occurring, multifunctional, degradable, non-toxic biopolymer. It is glutamic acid produced by fermentation of Bacillus subtilis. PGA is a cross-link between α-amino and γ-carboxyl groups of glutamic acid monomers, with a degree of polymerization of about 1000-15000. This product is water-soluble, edible, non-toxic to the human body, and environmentally friendly. It has a wide range of applications in medicine, food, cosmetics, water treatment and other fields.

Description

γ-Polyglutamic acid (γ-PGA) is a viscous amino acid polymer that was first discovered in natto and can be produced by microbial fermentation. Its structure is a high molecular weight polymer in which glutamic acid units form peptide bonds through α-amino and γ-carboxyl groups. The molecular weight ranges from 50,000 to 2 million Daltons, which is equivalent to about 500 to 5,000 glutamic acid monomers.

PGA has a large number of side chain carboxyl groups on the molecular chain, which can form hydrogen bonds within or between molecules, and has extremely high water absorption and moisturizing properties. Its unique physical, chemical and biological properties such as good film-forming, fiber-forming, plasticity, and adhesion have a wide range of applications in the field of skin care products.

In the field of cosmetics, γ-polyglutamic acid is widely used in various skin care products, such as lotions, creams, essences, masks, etc. It can work synergistically with other skin care ingredients to provide comprehensive care for the skin. In the field of agriculture, γ-polyglutamic acid also has important application value. It can be used as a fertilizer synergist to improve fertilizer utilization and reduce the use of chemical fertilizers. At the same time, it can also improve soil structure, increase soil water and fertilizer retention capacity, and promote plant growth and development.

Product Features

NO01

Eco-friendly

γ-PGA can be decomposed by organisms, is non-toxic to the human body and the environment, has good biocompatibility, and is nutritious to the skin.

NO02

Water-soluble

γ-PGA has good water-soluble properties, and its aqueous solution can be hydrolyzed into glutamic acid under certain conditions. In addition, it has high water absorption and moisturizing properties, and is used as a moisturizer in the cosmetics industry.

NO03

Multi-dimensional moisturizing

The combination of sodium polyglutamate of different molecular weights can produce a synergistic effect, repairing the skin barrier from the inside out in multiple dimensions, achieving the effect of three-dimensional repair and moisturizing, and multiple skin care.
