Trideceth-6 Phosphate
What is Trideceth-6 Phosphate?
Trideceth-6 phosphate is a synthetic anionic surfactant created by phosphorylating trideceth-6, a polyethylene glycol ether derived from tridecyl alcohol ethoxylated with six units of ethylene oxide. This chemical modification imparts phosphate groups, enhancing its water solubility and surface-active properties. Primarily used in rinse-off products like shampoos, body washes, and facial cleansers, as well as leave-on emulsions such as lotions and creams, it functions by lowering the surface tension of liquids. This allows it to lift dirt, excess oils, and impurities from the skin and hair while generating foam. As an emulsifier, it forms a stable interfacial film between oil and water phases, preventing separation and ensuring uniform product texture and application. Its mild nature suits everyday personal care formulations.
