BUTYLENE GLYCOL OLEATE.

Valuable CAS 107425-65-0 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A dual-purpose fatty acid ester that serves as both an emollient and co-emulsifier in skincare formulations. This oleic acid derivative creates a protective lipid barrier while stabilizing oil-in-water emulsions for improved product texture and delivery.

emollient emulsifying skin conditioning

Science

Forms a thin lipid film on the stratum corneum to reduce transepidermal water loss and smooth skin texture, while simultaneously acting as a lipophilic emulsifier that enhances the solubilization and delivery of oil-soluble actives
