About

A castor oil-derived PEG ester used as an emulsifier and solubiliser with a generally benign safety profile.

PEG-2 ricinoleate is the polyethylene glycol ester of ricinoleic acid derived from castor oil. It functions as a nonionic surfactant and emulsifier in cosmetic formulations. PEG chain length of 2 indicates relatively low ethoxylation. The ingredient is not listed in EU Annex II (prohibited substances) or Annex III (restricted substances). Ricinoleic acid derivatives are widely used and considered safe at cosmetic concentrations, though any PEG ingredient requires assessment for residual ethylene oxide.
