About

Nonyl Nonoxynol-15 Phosphate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

NONYL NONOXYNOL-15 PHOSPHATE is the phosphate ester of nonoxynol-15, combining moderate ethoxylation (15 EO) with the phosphate functionality and nonyl phenyl moiety. The higher EO count relative to -11 reduces nonyl phenol metabolite concerns somewhat. However, nonyl phenyl ethoxylates remain under EU REACH scrutiny for endocrine-disruption and environmental toxicity. The substance is not specifically listed in EU cosmetics Annexes II or III, but falls into the category of substances of concern similar to Annex III restricted compounds.
