Mono-n-dodecyl phosphate is widely used as an emulsifier and surfactant in various industrial and consumer products. It is particularly effective in stabilizing oil-in-water emulsions, making it a key ingredient in personal care items such as shampoos, conditioners, and skin creams. Its ability to reduce surface tension enhances the spreadability and absorption of these products.

In the industrial sector, it is utilized as a corrosion inhibitor, protecting metal surfaces from degradation in aqueous environments. Additionally, it serves as a dispersing agent in formulations like paints, coatings, and agrochemicals, ensuring even distribution of particles and improving product performance. Its applications also extend to the textile industry, where it aids in fabric softening and dye dispersion processes.
