Feature:
Polyglutamic acid is also known as natto gum and polyglutamic acid. It is a water-soluble, biodegradable, non-toxic, biopolymer prepared by microbial fermentation. Polyglutamic acid is a sticky substance and was first discovered in "Natto"-fermented beans. γ-PGA polyglutamic acid is a special anionic natural polymer. The molecular weight of homopolyamide is composed of amide bond between α-amine group and γ-carboxyl group from 50,000 to 2 million daltons. Don't wait. Polyglutamic acid has excellent water solubility, super adsorption and biodegradability, and the degradation product is pollution-free glutamic acid. It is an excellent environmentally friendly polymer material and can be used as a water retaining agent and heavy metal ion adsorption Agents, flocculants, slow-release agents and drug carriers, etc., have great commercial and social value in cosmetics, environmental protection, food, medicine, agriculture, desert management and other industries.
POLY-L-GLUTAMIC ACID (γ-PGA) has the following applications/functions:
Moisturizing effect
Polyglutamic acid is the main component of natto viscous colloid, which can promote mineral absorption. At present, Japan has listed polyglutamic acid in the list of health ingredients that promote mineral absorption. The special molecular structure of polyglutamic acid gives it extremely strong moisturizing ability. Adding polyglutamic acid to cosmetics or skin care products can effectively increase the moisturizing ability of the skin and promote skin health. Compared with the recognized hyaluronic acid with the most moisturizing ability, the moisturizing effect of polyglutamic acid is 2-3 times more than its effect. It is a new generation of bio-tech moisturizing ingredient. Polyglutamic acid can form a water reticulum on the surface skin to reduce the loss of water molecules, and can penetrate deep into the inner layer to increase the content of natural moisturizing factors to achieve the purpose of efficient water retention. Under smart conditioning, the skin contains The amount of water reaches a full state. Compared with other moisturizing products, polyglutamic acid has many advantages such as non-toxic to the human body and the environment; biodegradable; good water solubility to obtain an odorless and transparent solution; easy to crosslink and form a hydrogel with excellent performance in the later stage; fully applicable For all skin conditions, polyglutamic acid can increase skin elasticity, feel good to touch, inhibit melanin, whiten the skin, inhibit the growth of microorganisms, play an antibacterial effect, slow biodegradability, and it is not easy to breed microorganisms on the skin surface.
