Sorbitan Sesquioleate

A derived emulsifier made from sorbitol and oleic acid, used to help blend oil and water-based ingredients. Sorbitan esters are assessed as safe in cosmetics by the CIR, though people with sensitive skin or known sensitivities to oleic acid should patch test before broad application.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
