Science
Mechanism of Action
As a derivative of proline, an amino acid crucial for collagen synthesis, Potassium Cocoyl Proline delivers mild cleansing and significant skin-conditioning effects. It works to improve skin texture by promoting softness and smoothness, contributing to hydration due to proline's role in maintaining skin integrity. This ingredient also acts as a gentle surfactant.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that amino acid alkyl amides, including cocoyl proline, are safe for use in cosmetics when formulated to be non-irritating, with typical usage levels up to 5%. While L-Proline itself is FDA-recognized as GRAS, a specific FDA or SCCS status for Potassium Cocoyl Proline as a cosmetic ingredient was not explicitly identified.
