Gamma-polyglutamic acid (gamma-pga, h form), gamma-polyglutamates and gamma-polyglutamate hydrogels for use as super moisturizers in cosmetic and personal care products

摘要

The present invention relates to the use of γ-polyglutamic acid (γ-PGA, H form), and/or one or more of its salts (i.e., γ-polyglutamate in Na⁺ form, γ-polyglutamate in K⁺ form, γ-polyglutamate in NH₄⁺ form, γ-polyglutamate in Mg⁺⁺ form, γ-polyglutamate in Ca⁺⁺ form) and/or γ-polyglutamate hydrogel as super moisturizer(s) in cosmetic products and personal care products.
