In skin care formulas, it serves much the same function as oleic acid – that is, as a skin conditioning, emollient ingredient. This ester does not maintain the irritant or drying properties for skin that pure ethanol (alcohol) has. Ethyl oleate can be lab-created and is also found naturally in plants such as neem and cinnamon. In its raw form it is a clear to pale yellow liquid. Its fluid nature lends excellent spreadability to cosmetics. A formal safety assessment of ethyl oleate hasn’t been done; however, oleic acid is considered safe for skin. Usage levels of ethyl oleate in cosmetics have not been firmly established. Related ingredients: 1,1-Dimethyl-2-Phenylethyl Isobutyrate
