DefinitionThis section has been translated automatically.
Pentaerythrityl refers to the tetravalent alcohol pentaerythritol (also called pentaerythritol), which is quadruple esterified with oleic acid in pentaerythrityl tetraoleate. The prefix "penta" refers to the 5 carbon atoms of the molecule. Pentaerythrityl tetraoleate ("oleate" refers to the ester of oleic acid) is used in cosmetic formulations. The tetraester acts as an emollient (makes the skin smooth and supple) and as a viscosity regulator (increases or decreases the viscosity of cosmetic products).
