About
A lightweight emollient ester that spreads easily on skin — helps formulations feel less greasy while conditioning effectively.
PEG-2 Oleate is a polyethylene glycol (2 EO units) monoester of oleic acid. It functions as a skin-conditioning agent, emollient, and surfactant in cosmetic formulations. The short PEG chain gives it some water solubility while the oleic acid moiety provides lipophilicity. It is used at low to moderate concentrations (typically 1–10%) in skincare and haircare products. Concerns are minimal at cosmetic levels, though PEG esters can potentially be contaminated with residual ethylene oxide or 1,4-dioxane if improperly purified. The short PEG chain (2 units) means systemic absorption is very low.
