Product Introduction
Sodium L-Pyroglutamate (Sodium PCA), CAS 28874-51-3, is a sodium salt of L-pyroglutamic acid, naturally derived from glutamic acid. As a primary component of the skin's Natural Moisturizing Factor (NMF), Sodium PCA plays a vital role in maintaining optimal skin hydration levels by attracting and binding water molecules from the environment. Its exceptional hygroscopic properties make it one of the most effective humectants available for cosmetic formulations, outperforming traditional moisturizers such as glycerin and propylene glycol. Sodium PCA is highly compatible with all skin types, including sensitive and reactive skin, and is extensively used in premium facial moisturizers, anti-aging serums, hydrating toners, body lotions, and hair conditioning products.
