About
A pentaerythritol tetraester of oleic acid — a rich, cushioning emollient and structuring agent. CIR-supported safe.
Pentaerythrityl tetraoleate (CAS 19321-40-5) is a tetraester formed from pentaerythritol (a four-OH polyol) and four oleic-acid units. It functions as a non-volatile emollient, structurant, and emulsion stabilizer in creams, lipsticks, and balms, contributing rich slip and texture. CIR has reviewed the pentaerythrityl ester family extensively as safe for cosmetic use. No CMR, endocrine, or significant GHS hazards. Skin tolerance is generally excellent; can feel heavy on very oily complexions and is sometimes flagged as mildly comedogenic in acne-prone users.
