About
A low-ethoxylation polyethylene glycol oleate ester surfactant used as an emulsifier in cosmetic formulations, derived from oleic acid and offering moderate water solubility with effective oil-wetting properties.
Poly(oxy-1,2-ethanediyl), α-(1-oxo-9-octadecenyl)-ω-hydroxy-(Z)- with an average of 5 mol EO. Functions as a nonionic emulsifier and co-surfactant. Not restricted in EU Regulation (EC) No 1223/2009; listed in CosIng without Annex II or III entries. The short 5 mol EO chain provides moderate hydrophilicity and effective oil-wetting performance. PEG-oleate esters are well-studied in cosmetic safety reviews with no significant concerns at use concentrations.
