  • Applications

    Pentyl stearate, also known as octadecanoic acid, pentyl ester (CAS number: 6382-13-4), is mainly used as an emollient in cosmetics and personal care, delivering a smooth feel on skin and hair. It also acts as a solvent or carrier for fragrance ingredients and actives in personal care formulations and household products. In the plastics and coatings sector, it serves as a plasticizer and processing aid to improve material workability. It functions as a lubricant or slip agent in industrial manufacturing and polymer processing. Additionally, it may appear as a component in household cleaners to enhance texture, slip, and emulsion stability.
