Cosmetic Grade CAS 25513-46-6 PGA Polyglutamic Acid Powder/Y-Polyglutamic Acid

What is Polyglutamic Acid/Y-Polyglutamic Acid ?

Polyglutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. γ-PGA polyglutamic acid is a sticky substance first discovered in natto, the fermented bean. The molecular weight of γ-PGA ranges from 50,000 to 2 million daltons. Its moisturizing and water-locking effect is 500 times that of hyaluronic acid. It is mainly used for moisturizing, whitening, antibacterial, and promoting skin health.

Polyglutamic acid is a sticky substance first discovered in "natto" - fermented soybeans. Polyglutamic acid is a special anionic natural polymer, which is a homopolyamide (amide linkage) composed of α-amino group (α-amino) and Y-carboxyl group (Y-caboxyl) through amide linkage. The molecular weight of homo-polyamide) Y-PGA ranges from 50,000 to 2 million Daltons. Its moisturizing and locking effect is 500 times that of hyaluronic acid.

Application:

1. The main role of polyglutamic acid in cosmetics and skin care products is a moisturizer and skin conditioning agent, with a risk factor of 1. It is safe to use and generally has no effect on pregnant women.

2. Polyglutamic acid has a good promotion of the activity of fibroblast cells, etc., has a skin revitalizing effect, and can be used in anti-aging and anti-wrinkle cosmetics; polyglutamic acid with a larger molecular weight does not promote the activity of fibroblast cells as well as small molecular weight, but its performance in stabilizing foam, moisturizing ability, and adsorption on hair is better than small molecular weight products, and it is used in hair water, which can be anti-static and hair soft' polyglutamic acid has the effect of skin whitening.
