Applications

sodium PCA (Ajidew NaPCA, Nalidone) is a high-performance humectant given its moisture-binding ability. Sodium PCA is a component of the skin’s natural moisturizing factor. For cosmetic use, it is derived from amino acids. It is considered a noncomedogenic, non-allergenic raw material recommended for dry, delicate, and sensitive skins.
