Avoid CAS 39464-64-7 / CLEANSING, SURFACTANT - CLEANSING

NONYL NONOXYNOL-10 PHOSPHATE is a synthetic surfactant primarily utilized for its emulsifying and cleansing properties, facilitating the stable blending of oil and water phases in cosmetic formulations. Despite its functional utility, its safety profile is largely uncharacterized and raises significant concerns for dermal application.

Science

Mechanism of Action

As a member of the broader nonoxynol family, NONYL NONOXYNOL-10 PHOSPHATE functions by reducing the surface tension between immiscible liquids, such as oil and water. This property allows for the formation of stable emulsions, acting as an effective emulsifying agent. Its surfactant characteristics also enable it to serve as a cleansing agent, solubilizer, wetting agent, and foam booster within various formulations.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel in 1982 deleted Nonoxynol-10 Phosphate from their report due to a critical lack of data, indicating no dedicated safety assessment. This ingredient is part of the Nonoxynol family, which is banned for use in cosmetics and personal care products marketed within the European Union due to safety concerns. While certain related Nonoxynols are permitted by the FDA as indirect food additives, and Nonoxynol-9 is an over-the-counter spermicide with specific warnings, the cosmetic ingredient status of NONYL NONOXYNOL-10 PHOSPHATE by the FDA is not explicitly established in available data. It has a reported high irritancy potential.

Verdict

Avoid

Given the insufficient safety data, its prohibition in the EU, and a reported high irritancy potential, NONYL NONOXYNOL-10 PHOSPHATE is strongly advised against for use in skincare formulations.
