  • Applications

    Ethyl palmitoleate (CAS 56219-10-4) is commonly used in cosmetics and personal care as an emollient, a light solvent, and a carrier oil for lotions, oils, and creams; it also serves as a softening agent and primary solvent in coatings and inks, aiding processability and gloss. In polymers and plastics, it is used as a plasticizer and processing aid to increase flexibility and workability of resin systems; in industrial manufacturing it can function as a lubricant or processing solvent for oil-based formulations; in cleaning and household products it may be used as a non-polar solvent component or solubilizer to improve formulation performance.
