Gamma Polyglutamic Acid
Product Introduction
Gamma Polyglutamic Acid also is called Polyglutamic Acid or Sodium Polyglutamate which appears as a white to pale yellow powder and is water-soluble. Gamma Polyglutamic Acid boasts a unique structure composed of multiple glutamic acid units linked together through peptide bonds. Gamma Polyglutamic Acid is a naturally occurring biopolymer having exceptional water-retention properties, making it a powerful humectant. It forms a breathable film on the skin, enhancing moisture retention and promoting a smoother, more supple complexion. Additionally, Gamma polyglutamic Acid has antioxidant properties, protecting the skin from environmental stressors.

Gamma Polyglutamic Acid finds versatile applications in cosmetics and skincare due to its remarkable hydrating properties. Acting as a potent humectant, Gamma Polyglutamic Acid attracts and retains moisture, promoting optimal hydration levels in the skin. It forms a breathable film, enhancing the skin's natural barrier function and preventing moisture loss. Gamma Polyglutamic Acid's lightweight texture and non-greasy feel make it suitable for various formulations, including moisturizers, serums, and masks. Additionally, it has antioxidant properties that help protect the skin from environmental damage, contributing to a more youthful and radiant complexion.
