Product Description

  

     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.

Function:

Polyglutamic acid is a homopoly amino acid formed by linking glutamic acid monomers through amide bonds. It has environmentally friendly, super strong adsorption capacity, super high water absorption and moisture retention capacity, and good biodegradability. Synergistic fertilizers added with polyglutamic acid have significant application effects in water conservation, fertilizer conservation, yield increase, stress resistance, and improving crop quality.

Application:

Mainly used for moisturizing, whitening, antibacterial and promoting skin health. Polyglutamic acid was first found to exist in the highly viscous drawing of Japanese natto food (fermented small soybeans), and it is referred to as Y-PGA in China. Biopolymerization through liquid fermentation produces decomposable high-molecular amino acid polymers.
