Ethylhexyl Palmitate is an ester of 2-ethylhexyl alcohol and palmitic acid. It is an alternate to silicone-based ingredients offering a 'dry-slip' feel. It helps adjust consistency in skin-care products.
Ethylhexyl palmitate is a mixture of a fatty alcohol and palmitic acid that functions in cosmetics products as an emollient (meaning it can soften and smooth skin), texture enhancer, and solvent in amounts from 2–50%, depending on the type of formula and desired aesthetics. It improves the look of skin, particularly dry skin, by helping reduce moisture loss from its upper layers. As a solvent, it helps solubilize other ingredients, helping active ingredients more readily penetrate skin. It helps sunscreen active ingredients such as avobenzone and ethylhexyl triazone disperse and remain evenly suspended in a formula.
Ethylhexyl palmitate has a feel like some silicones and silicone derivatives, making it an alternative to those ingredients in certain formulations. There’s no research indicating this ingredient, which may be synthetic, plant-, or animal-derived, is a problem for skin. Paula’s Choice Skincare uses either the synthetic or plant-derived form of this ingredient depending on the product.
