Sodium Polyglutamate (Sodium Polyglutamate)

A water-soluble cosmetic polymer derived from glutamic acid, valued for its excellent moisturizing, smoothing and skin comfort-enhancing properties. By forming a fine, flexible film on the skin’s surface, it helps reduce transepidermal water loss, supports a plumper, softer and more elastic skin feel, and contributes to a fresher, smoother and more radiant appearance. It is especially useful in hydrating serums, lightweight creams, masks, lotions and anti-aging formulas, where it complements classic humectants, improves the sensory texture of the product and leaves the skin with a silky, comfortable and well cared-for finish.
