Trilaureth-4 Phosphate
What is Trilaureth-4 Phosphate?
Trilaureth-4 Phosphate is a synthetic anionic surfactant produced by phosphorylating trilaureth-4, an ethoxylated derivative of lauryl alcohol with four ethylene oxide units. This imparts amphiphilic properties, with a charged phosphate head attracting water and hydrophobic tails binding oils. Commonly found in rinse-off products like shampoos, shower gels, and facial cleansers, as well as leave-on emulsions such as moisturizers and sunscreens. In formulations, it lowers interfacial tension to remove soils, sebum, and makeup during washing, while its emulsifying action creates stable blends by coating dispersed phases and preventing coalescence. The structure allows mild interaction with skin lipids compared to harsher surfactants, supporting gentle performance in personal care items across hair and body categories.
