Potassium Cetyl Phosphate
What is Potassium Cetyl Phosphate?
Potassium Cetyl Phosphate is a synthetic potassium salt derived from cetyl alcohol, a long-chain fatty alcohol often sourced from plant oils like palm or coconut, reacted with phosphoric acid to form a monoalkyl phosphate ester. It serves as a key ingredient in oil-in-water emulsions, including moisturizers, sunscreens, shampoos, and body washes. Functionally, it acts at the oil-water boundary, reducing interfacial tension to form a protective film that prevents phase separation, ensuring product stability and even consistency. This enables easy spreading and absorption on skin. As an anionic surfactant, it contributes to mild foaming and cleansing by dislodging impurities while maintaining skin's moisture barrier, supporting formulations designed for daily use across various skin types.
