About Poly-L-Glutamic Acid
Poly-L-Glutamic Acid is a substance that can dissolve water, is biodegradable, non-toxic, and can be converted into microbial polymer materials after fermentation.
Poly-L-Glutamic Acid generates biopolymers through fermentation, which has a good effect on skin beautification. It can improve the elasticity of the skin and has a very good moisturizing and hydrating effect.
Poly-L-Glutamic Acid is a polymer of amino acids, which is polymerized by the amidation reaction between the amino group of glutamic acid (GA) and the carboxyl group at the γ-position of another glutamic acid. The usual peptide bond is composed of The amino group is amidated with the carboxyl group at the α-position of another amino acid.
The moisturizing and water-locking effect of Poly-L-Glutamic Acid is 500 times that of hyaluronic acid. Mainly used for moisturizing, whitening, antibacterial, and improving skin health. Poly-L-Glutamic Acid can greatly promote the activity of fibroblasts, etc., has a skin revitalizing effect, and can be used in anti-aging and anti-wrinkle cosmetics. Poly-L-Glutamic Acid with a larger molecular weight does not promote the activity of fibroblasts as well as Poly-L-Glutamic Acid with a small molecular weight, but its performance in stabilizing foam, moisturizing ability, and adsorption on hair is worse than that of small molecular weight products. It can be used in hair lotion to resist hair loss. Static electricity makes hair smooth and Poly-L-Glutamic Acid has the effect of whitening skin.
