Pentaerythrityl refers to the tetravalent alcohol pentaerythritol (also called pentaerythritol), which is quadruple-esterified with stearic acid (octadecanoic acid) in pentaerythrityl tetrapelargonate. The prefix "penta" refers to the 5 carbon atoms of the molecule. Pentaerythrityl tetrastearate ("stearate" refers to the ester of stearic acid) is used in cosmetic formulations. It acts as an emollient (makes the skin smooth and supple) and as a viscosity regulator (increases or decreases the viscosity of cosmetic products).
