Didecyl phosphate is widely used as an emulsifier and surfactant in various industrial applications. It plays a key role in the formulation of lubricants, where it enhances the stability and performance of oil-water emulsions. In the agricultural sector, it is utilized in pesticide formulations to improve the dispersion and adherence of active ingredients on plant surfaces. Additionally, it finds application in the production of personal care products, such as creams and lotions, where it helps to stabilize emulsions and provide a smooth texture. Its ability to reduce surface tension also makes it valuable in cleaning agents and detergents for effective removal of dirt and grease.
