What It Does
Potassium Cetyl Phosphate is an anionic phosphate ester derived from cetyl alcohol (C16) and phosphoric acid, neutralized with potassium hydroxide. This mild emulsifier is particularly valued in natural and organic cosmetics for creating stable oil-in-water emulsions with a light, elegant skin feel, while also providing secondary conditioning benefits. Formulators choose it for its ability to produce creams and lotions with excellent spreadability and a non-greasy after-feel, along with its compatibility with sensitive skin formulations and acceptance in natural cosmetic certifications.
