  • Applications

    Dimyristyl phosphate is a long-chain phosphate ester commonly used as a surfactant and emulsifier in cosmetics and personal care formulations, providing improved texture and stability for creams and lotions; it also serves as a waxy plasticizer and processing aid for polymers such as PVC and other thermoplastics, enhancing flexibility and processing during extrusion or molding; in coatings, inks and adhesives it acts as a lubricating additive and surface-active agent to improve spread, leveling and film formation; it can function as an intermediate in the synthesis of other phosphate esters and specialty plasticizers used in industrial formulations; in cleaning formulations, it may act as a nonionic surfactant or coupling agent to aid cleaning performance; its use is typically formulation-dependent and subject to local regulations and limits.
