  • Applications

    Dicetyl Phosphate (CAS 2197-63-9) is commonly used as an amphiphilic phosphate ester surfactant and emulsifier in cosmetic and personal care formulations, where it aids stabilization of oil-in-water systems, improves texture, and facilitates the dispersion of active ingredients. It is also employed in household and industrial cleaning products as a surface-active agent and wetting additive to enhance cleaning performance. In coatings, inks, and paints, it acts as a dispersing agent and emulsifier to improve pigment stability and formulation uniformity. In polymer and plastics processing, it serves as a processing aid and lubricant to facilitate mixing and extrusion, and can act as a stabilizer for emulsion polymerizations in certain formulations. It may also be used in adhesives to improve wetting and adhesion on challenging substrates, depending on formulation.
