In the previous Paper, authors studied the effect of inorganic builders on detergency of nonionic surfactant (polyoxyethylene nonyl phenyl ether (EO) 10 mol).<BR>In this paper, the relationship between detergency of a nonionic surfactant and its surface active properties (surface tension, wetting, foaming and emulsifying powers, solubilization and dispersion) was investigated in comparison with two usual anionic detergents (sodium lauryl sulfate and sodium dodecylbenzene sulfonate). As a result, it was found that the same surface active properties contributed to washing with both nonionic and anionic surfactants, but the type of those effective properties changed depending on the character of soils.<BR>Washing efficiency of nonionic surfactant was selective depending on soils.
