Octoxynol-10
What is Octoxynol-10?
Octoxynol-10 is a synthetic nonionic surfactant, chemically a p-(1,1,3,3-tetramethylbutyl)phenyl ether condensed with 10 moles of ethylene oxide. This alkylphenol ethoxylate is produced through ethoxylation of octylphenol and serves primarily in rinse-off products like shampoos, shower gels, and makeup removers, as well as some leave-on emulsions such as creams and lotions. It works by reducing surface tension at interfaces, allowing water to spread and penetrate, which aids in dislodging soils, sebum, and residues from skin and hair. As an emulsifier, it forms a protective film around oil droplets in water, preventing coalescence and maintaining product homogeneity for even application and feel. Its structure enables mild yet effective performance in diverse formulations.
