Sodium Palmitoyl Proline
What is Sodium Palmitoyl Proline?
Sodium Palmitoyl Proline is the sodium salt of N-palmitoyl-L-proline, combining proline—an amino acid present in skin proteins—with palmitic acid, a saturated fatty acid from vegetable sources. Classified as a skin conditioning agent, it appears in moisturizers, lotions, and cleansing products. It functions by creating a lightweight film on the skin to aid moisture retention and improve texture, while its surfactant-like properties help blend oil and water phases for better product stability and application. This ingredient supports skin comfort by softening the surface without heaviness, making it suitable for various formulations targeting hydration and suppleness.
