Dimyristyl phosphate

Dimyristyl phosphate (CAS 6640-03-5), also sold as ditetradecyl phosphate, is a phosphate ester of myristic alcohol used as an emulsifier and surface-active agent in specialty formulations.

Where is Dimyristyl phosphate used?

• Personal care: builds stable emulsions in creams and lotions, phosphate head group contributes to skin-feel and texture control
• Pharmaceutical: lipid-based drug delivery systems, including liposomal and vesicular carriers, helps define membrane structure and encapsulation efficiency
• Biotechnology: engineers lipid bilayer models and cell membrane mimics for research and assay development
• Surface modification: treatment of particulate systems where controlled charge and wettability affect dispersion stability in suspension formulations and industrial coatings
• It stabilizes oil-water interfaces and modifies surface charge, enabling formulators to control emulsion structure and ingredient delivery.

Commercial specifications

• Purity levels commonly at 98% or higher for technical and formulation use
• Packaging from small quantities for laboratory use to bulk formats for commercial production
