Pentaerythrityl Tetrabehenate is the fully esterified product of pentaerythritol with behenic acid (C22), the longest-chain fatty acid commonly used in cosmetics. With four C22 chains, this molecule is a high-melting-point, waxy solid at room temperature. It functions as a heavy-duty emollient and thickener in rich creams, body butters, and lip balms. The long behenic chains create an exceptionally substantive, long-lasting occlusive film that is excellent for very dry or compromised skin.
