Sodium PCA protects the skin against dryness by binding moisture to your dermis. It attracts water to the skin from the surrounding air. Added to anti-wrinkle and/or anti-oxidant creams, lotions and any product with a water phase will make a NOTICEABLE difference!! Sodium PCA is the sodium salt of pyroglutamic acid (also known as PCA). PCA is a naturally occurring component of human skin and a part of the "natural moisturizing factors" (NMF) that maintain a healthy epidermis. Sodium PCA is very hygroscopic, attracting moisture from the air. It imparts a moist feeling to hair and skin. Sodium PCA applied to the skin is absorbed to a limited extent. It is non-comedogenic, nonirritating to the eye and skin -- even at concentrations up to 50%, and does not contribute to phototoxicity or sensitization. It is rapidly biodegradable. Soluble in water and ethanol and insoluble in oils, it is used for its powerful humectant properties in many skin and hair care products including gels, creams, lotions, shampoos, conditioners, lipsticks and foundations.
