Sodium Polyglutamate

γ-PGA，a biodegradable, water-soluble biopolymer derived from glutamic acid via Bacillus subtilis fermentation . As a multifunctional cosmetic ingredient, it serves as a natural humectant with exceptional moisture retention, outperforming hyaluronic acid in hydration efficiency .

Its high density of carboxyl groups enables hydrogen bonding, forming a protective film to reduce transepidermal water loss and enhance skin elasticity .

In cosmetics, it is widely used in formulations like serums, creams, and masks (0.1%-1% dosage) for:

Long-lasting hydration: Synergizes with hyaluronic acid to improve texture and reduce stickiness .

Brightening: Inhibits melanin biosynthesis and promotes natural moisturizing factor synthesis .

Anti-aging: Stimulates collagen production and neutralizes free radicals .

Sensitivity relief: Buffers pH 2-6 environments, suitable for sensitive skin .

Certified by COSMOS and compliant with China's 2021 Cosmetic Ingredient Directory, it is recognized as low-risk (GRAS) with no reported comedogenicity . Major applications span moisturizers, cleansers, and sunscreens, offering a sustainable alternative to synthetic polymers.
