FSS SODIUM PCA FSS Sodium PCA is a highly effective humectant widely used in cosmetic and personal care formulations to enhance skin hydration and comfort. As the sodium salt of pyrrolidone carboxylic acid (PCA), it is a naturally occurring component of the skin’s Natural Moisturizing Factor (NMF), making it exceptionally skin compatible. FSS Sodium PCA works by attracting and binding moisture from the environment, helping to maintain optimal hydration levels and improve skin softness, smoothness, and elasticity. It provides long-lasting moisturization without a sticky or heavy feel, making it suitable for lightweight, as well as rich formulations. This ingredient is gentle, non-irritating, and effective at low concentrations, which makes it ideal for a wide range of products including creams, lotions, serums, cleansers, toners, shampoos, and conditioners. It supports the skin barrier and leaves both skin and hair feeling supple and conditioned. Benefits: • Conditioning • Humectant • Solvent FSSR00328 Water & Sodium PCA
