What it is
Ethyl Linoleate is an ester formed from linoleic acid, an essential polyunsaturated fatty acid, and ethanol. In skincare and sunscreen formulas it functions as a lightweight emollient that conditions and softens the skin and can support the appearance of the skin barrier. It is used at modest levels and does not provide UV protection.
Safety & warnings
Ethyl Linoleate is generally well tolerated and is not a recognized fragrance allergen. Because it is a polyunsaturated fatty acid ester it is prone to oxidation over time, which is why formulas containing it usually include antioxidants. It is considered to have low comedogenic potential, though very oil-rich formulas may not suit acne-prone skin.
Origin & sourcing
Derived from linoleic acid obtained from plant oils such as safflower or sunflower, esterified with ethanol; it can also be prepared synthetically.
