Concern level
High concern
Potassium cetyl phosphate is a potassium salt of cetyl phosphate used mainly as an anionic emulsifier and surfactant. It helps stabilize oil-in-water emulsions, improves spreadability, and is widely used in creams, lotions, sunscreens, and cleansers. CIR-reviewed data describe it as safe as used, though it may be mildly irritating to sensitive skin.

Interactions
incompatible with: May be less comfortable in formulas with strong surfactants or harsh cleansing systems., Can be destabilized if the emulsion system is not properly balanced with co-emulsifiers and pH control.
Risks & Warnings
Generally low risk, but it can cause mild irritation in very sensitive skin or at higher use levels. As with most surfactant/emulsifier systems, irritation risk rises when formulas are harsh, low in humectants, or combined with stronger cleansing agents.
