NONYL NONOXYNOL-11 PHOSPHATE.

Insufficient Data CAS 39464-64-7 / CLEANSING

NONYL NONOXYNOL-11 PHOSPHATE is a synthetic ingredient functioning primarily as a surfactant and emulsifier. It facilitates the stable blending of immiscible substances like oil and water, supporting cleansing and foam generation in formulations. The included phosphate group further enhances its wetting capabilities.

Science

Mechanism of Action

As a surfactant, NONYL NONOXYNOL-11 PHOSPHATE reduces the surface tension between different phases, enabling effective emulsification and dispersion. This action allows it to cleanse the skin and hair by solubilizing oils and impurities, while also stabilizing formulations by preventing phase separation. The phosphate moiety contributes to surface wetting and can offer corrosion inhibition properties.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Moderate

The CIR Expert Panel assessed general nonoxynols, including Nonoxynol-11, as safe, but explicitly excluded phosphate derivatives like NONYL NONOXYNOL-11 PHOSPHATE from their assessment due to a lack of specific safety data. This ingredient belongs to the Nonylphenol Ethoxylate (NPE) class, which can degrade into Nonylphenols (NPs), known endocrine-disrupting chemicals with environmental concerns. The European Union restricts NPEs and NPs. Related compounds, such as Nonyl Nonoxynol-9 Phosphate, are flagged by EWG Skin Deep for low to moderate concerns regarding cancer, allergies, immunotoxicity, and developmental/reproductive toxicity, leading to restrictions in EWG VERIFIED products due to potential toxic impurities, enhanced skin absorption, and persistence. No specific SCCS opinion or FDA cosmetic status is available for this ingredient.
