| Abstract;The influence of polyoxyethylene lauryl ethers on the binding of stearyltrimethylammonium chloride (STAC) to human hair was investigated. The nonionic surfactants decreased the amount of bound STAC to hair. The effect was more prominent with the nonionic surfactant with a longer polyoxyethylene chain. The decreasing effect was correlated to the hydrophilicity of the nonionic surfactant. The binding of the nonionic surfactant of a long polyoxyethylene chain to hair was also decreased by STAC. The analysis of the isotherms of a Langmuir-type binding indicated that the surfactant having a long polyoxyethylene chain reduces both the binding sites in saturation and the binding constant. Thermodynamic study and the surface analysis by FT-IR or X-ray photoelectron spectroscopy (XPS) suggested that the decreasing effect was caused by the interaction of STAC with the nonionic surfactant of a long polyoxyethylene chain in the aqueous phase and on the hair surface.
