Sodium PCA is a naturally occurring humectant derived from amino acids, and is one of the key components of the skin’s Natural Moisturizing Factor (NMF). It attracts and retains moisture, improves skin texture, and enhances the feel and performance of personal care formulations for both skin and hair.
Sodium PCA (pyrrolidone carboxylic acid salt) is a highly effective humectant that binds moisture to the skin and hair. It’s derived from L-glutamic acid and is known for its high moisture-retention capacity. Because it is a natural component of healthy skin, it is especially gentle and non-irritating—even for sensitive skin types.
Add Sodium PCA to the water phase at room or warm temperatures (below 60°C). Use in combination with other humectants for long-lasting hydration synergy.
Water-soluble and easy to incorporate into cold-process or heated formulas.
