Ethylhexyl palmitate, or octyl palmitate, is the fatty acid ester derived from 2-ethylhexanol and palmitic acid. Ethylhexyl palmitate is commonly used in cosmetic formulations.^[1]

Chemical structure

Ethylhexyl palmitate is a branched saturated fatty ester, 24 carbons in length.

Physical properties

Ethylhexyl palmitate is a clear, colorless liquid at room temperature with a slightly fatty odor.

Palmitic acid and 2-ethylhexanol are reacted in the presence of an acid catalyst to make the ester.

Uses

Ethylhexyl palmitate is used in cosmetic formulations as a solvent, carrying agent, pigment wetting agent, fragrance fixative and emollient. Its dry-slip skinfeel is similar to some silicone derivatives.
