What Is Propylene Glycol Diethylhexanoate?
Propylene Glycol Diethylhexanoate is a synthetic emollient ingredient used in cosmetic formulations to soften and smooth the skin. It is an ester of propylene glycol and 2-ethylhexanoic acid. In addition to its emollient properties, it functions as a solvent and a texture-enhancing agent, helping to reduce the greasy or heavy feel of other oils and butters in a product, resulting in a lighter, more elegant skin feel. The Cosmetic Ingredient Review (CIR) Expert Panel has determined that Propylene Glycol Diethylhexanoate is safe for use in cosmetics, subject to concentration or use limitations to avoid irritation.
