What it is
Sodium Palmitoyl Proline is an amino-acid derivative formed by linking the fatty acid palmitic acid to the amino acid proline and neutralizing it as the sodium salt. This gives it both lipid and water-compatible character, so it conditions the skin and can act as a mild surfactant or emulsion aid. It is often used in skin care and sun care formulas as part of a barrier-friendly, amino-acid-based system.
Safety & warnings
Amino-acid lipids of this kind are generally regarded as gentle and well tolerated, and are often chosen for mild formulas. Adverse reactions are uncommon at the levels typically used.
Origin & sourcing
It is produced by combining palmitic acid with the amino acid proline; the components can be sourced from plant or other feedstocks and are joined synthetically.
Questions everyone asks
What is Sodium Palmitoyl Proline made from?
It combines the fatty acid palmitic acid with the amino acid proline, used as its sodium salt.
What role does it play in a formula?
It conditions the skin and can serve as a mild surfactant or emulsion aid thanks to its dual oil- and water-compatible structure.
