About

A triple-tailed ester built on a glycerol backbone with three isostearic acid chains and three PEG units — a heavy-duty emollient and emulsifier for rich formulations.

PEG-3 glyceryl triisostearate is a triester of glycerol with three isostearic acid chains and three polyethylene glycol-3 units attached. The glycerol backbone provides a strong skin-conditioning effect while the three isostearic acid chains contribute a rich, non-drying emolliency. The short PEG chains give some water solubility. This ingredient functions as an emulsifier and skin-conditioning agent, particularly suited to richer creams and body butters.
