Potassium Cetyl Phosphate
Potassium Cetyl Phosphate
An emulsifier that keeps oil and water blended, commonly used in lotions and in sunscreens to disperse UV filters evenly.
What it does
Potassium cetyl phosphate is an emulsifier that stabilizes the mix of oil and water in a formula. It shows up often in sunscreens and lotions, where even dispersion matters for consistent feel and, in sunscreens, even filter coverage. It is a behind-the-scenes formulation ingredient rather than an active.
