Undeceth-5
What is Undeceth-5?
Undeceth-5 is a synthetic non-ionic surfactant produced by reacting undecyl alcohol with approximately five moles of ethylene oxide, creating a polyoxyethylene chain. This structure gives it hydrophilic and lipophilic properties, making it ideal for cosmetic formulations. It appears in rinse-off products like shampoos, body washes, and facial cleansers, as well as leave-on items such as lotions and creams. In products, it works by lowering surface tension to remove oils, dirt, and makeup effectively during rinsing. As an emulsifier, it forms a protective film at the oil-water interface, preventing separation and ensuring even distribution of ingredients for a smooth application feel. Its relatively short ethoxylate chain contributes to milder performance compared to longer-chain variants, supporting its use in everyday personal care routines.
