Sodium polyglutamate(28829-38-1)

Polyglutamic acid, found in the traditional food natto, is a sticky anionic polymer of amino acids, commonly known as γ- Polyglutamic acid. The polymer is based on glutamic acid as the structural unit α– Amino and γ- Isomorphic polypeptide biopolymers with carboxyl groups forming amide bonds. Because each structural unit of glutamic acid contains many hydrophilic groups, a large number of hydrogen bonds can be formed inside or between the polymer chains, making polyglutamic acid have good water absorption and water retention, and become a good water retention component, which is widely used in cosmetics.

Polyglutamic acid has good biocompatibility and film-forming property, can ensure the accumulation of water-retaining ingredients in the skin, and enhance the energy of water-retaining factor (NMF). Reduce the amount of transdermal water loss.

It can ensure the inhibition of hyaluronidase activity, help maintain the content of hyaluronic acid, enhance the function of hyaluronic acid, and ensure skin quality. PGA has the energy to reduce free radicals and reduce skin cell damage caused by excess free radicals.

PGA can form a membrane to isolate and enhance the skin's resistance to external stimuli. It has a strong buffering force in PH2-6. It is very suitable for various cosmetics to maintain a healthy PH environment for the skin and resist chemical stimuli.

When used in combination with hyaluronic acid and other raw materials, it can work together to provide a smooth and moist feeling and reduce stickiness. The anionic functional groups on the monomers of polyglutamic acid can attract some functional components, and build an embedded sustained-release system to ensure its reasonable absorption and utilization.
