 2-Ethylhexyl palmitate (CAS NO.16958-85-3) 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.

  Palmitic acid and 2-Ethylhexanol are reacted in the presence of an acid catalyst to make 2-Ethylhexyl palmitate (CAS NO.16958-85-3). It also can be synthesized by using aminosulfonic acid as catalyst under the condition of reduced pres- sure. Instead of aminosulfonic acid, the enzyme can also be used as a catalyst such as the lipase from Candida sp. 99–125. After it is immobilized on surfactant modified cotton membrane, it can be used to prepare the 2-Ethylhexyl palmitate .

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