OLETH-3
Safety score · 0–100
Good
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A short-chain ethoxylated oleyl alcohol surfactant that helps oils and water mix in cosmetic formulations, leaving a relatively lightweight feel on skin due to its low ethylene oxide content.
Poly(oxy-1,2-ethanediyl), α-9-(Z)-octadecenyl-ω-hydroxy with an average of 3 mol EO. This nonionic surfactant serves as an emulsifier and co-surfactant in cosmetic formulations. No EU restrictions apply; the ingredient appears in the CosIng inventory without regulatory limits. Lower EO chain length increases lipophilicity and may slightly enhance skin penetration compared to higher-EO homologues.
Skin benefits
- Emulsifier enabling stable oil-in-water formulations
Known concerns
- May enhance penetration of other ingredients due to low EO chain
