NONOXYNOL-44
Safety score · 0–100
Caution
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A high-ethoxylate cousin of nonoxynol-9 used as an industrial emulsifier. Modern formulators avoid the nonoxynol family because of dioxane residue, mucosal irritation, and environmental endocrine concerns.
Skin benefits
- Non-ionic surfactant and emulsifier from the nonoxynol family, used historically to solubilise oils into water
- Can serve as a co-emulsifier in rinse-off systems
Known concerns
- Nonoxynol surfactants are flagged in the EU for potential 1,4-dioxane and ethylene oxide residues from manufacturing
- Nonoxynol-9 and related members have known mucosal irritation profiles, raising class concerns
- Strict limits exist on alkylphenol ethoxylates under REACH due to environmental endocrine activity
- Largely phased out of modern cosmetic formulations in favour of safer surfactants
