Polyglutamic Acid Powder Description

Polyglutamic Acid (PGA) which exists frequently in nature in the form of sodium polyglutamate, is usually a sticky anionic amino acid polymer. Initially, it was found in a traditional food 'natto', which is also called γ-Polyglutamic acid (γ-PGA). The polymer is an isomorphism type of polypeptide biopolymer with glutamic acid as a structural unit and connected by an amide bond.

Since each of the structural units of glutamic acid contains a plurality of hydrophilic groups, a large number of hydrogen bonds can be formed inside or between the polymer chains, so PGA can effectively capture and retain moisture, enhance skin elasticity, and be regarded as a good natural moisturizing ingredient widely used in personal care products. Our Hyafactor-PGA is produced by fermentation with a superior strain of Bacillus subtilis. Its INCI name is Sodium Polyglutamate.

Production process of polyglutamic acid、

The large-scale production of γ-PGA uses starch and glutamic acid as raw materials, which are refined through modern bioengineering technology and macromolecular crystallization separation technology.

Efficacy of Polyglutamic Acid Powder

γ-PGA has a unique molecular structure and is the most effective cosmetic moisturizer discovered so far.

※ It can absorb about 5,000 times its weight in water and thus enhances skin moisturizing function.
※ NMF generation of skin is endogenously enhanced, and the skin NMF increases in quantity remarkably after 28 days.
※ This can add extreme freshness and silkiness to skincare products without stickiness.

• Promote the Accumulation of NMFs
• High-Quality Moisturizing
• Reduce the Degradation of HA
• Improve Elasticity and Softness of the skin
• Inhibition of Melanin production
• Scavenge Free Radicals

Polyglutamic Acid (PGA) Powder Applications

• Emulsion, Mask, Concentrate, Essence, Cream, Cleanser; Hair care products, etc.
