Science
Mechanism of Action
This compound acts as a surfactant by significantly reducing the surface tension of liquids, enabling the miscibility of oil and water phases. In skincare, this property allows it to encapsulate and lift impurities from the skin's surface, promoting effective cleansing. Its ionic phosphate group contributes antistatic benefits, while the ethoxylate component enhances its detergency, wetting capabilities, and ability to generate foam and stabilize emulsions.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that alkyl phosphates, including POTASSIUM ETHYLHEXYL/ISOTRIDECETH-8 PHOSPHATE, are safe for use under current practices when formulated to be non-irritating. While a specific maximum concentration for this exact ingredient was not provided, other alkyl phosphates have been used up to 8.3% in mascaras and up to 4.2% in other leave-on dermal preparations.

Verdict
While POTASSIUM ETHYLHEXYL/ISOTRIDECETH-8 PHOSPHATE is a recognized surfactant and emulsifier with a general safety profile when formulated to be non-irritating, precise clinical efficacy data, specific skin type compatibility, irritancy, and comedogenicity data are currently insufficient for a definitive Moumoujus assessment.
