POTASSIUM CETYL PHOSPHATE
Is POTASSIUM CETYL PHOSPHATE safe for seborrheic dermatitis?
Potassium Cetyl Phosphate is not automatically unsafe for seborrheic dermatitis, but direct evidence is limited. It is an emulsifier and surfactant used to keep formulas stable rather than an active intended to treat a flare.
No applicable ingredient-specific evidence found for this page shows that Potassium Cetyl Phosphate feeds Malassezia. The word cetyl in its name is not enough to treat the finished phosphate surfactant as free palmitic acid. Judge the complete formula and stop if it repeatedly increases stinging, dryness or redness.

What is POTASSIUM CETYL PHOSPHATE used for in skincare?
Potassium Cetyl Phosphate helps oil and water remain mixed and can support cleansing or product texture. It is an anionic surfactant built from a cetyl group and phosphate, commonly used in creams and sunscreens. Its role is emulsion structure, not moisturising or antifungal treatment.
