• The detergency of clay particles, the major constituent in soiled cloth, was examined in cotton using ethanol aqueous solution. With a 60% ethanol aqueous solution, detergency was minimal, this being consistent with previous data observed for detergency of silica particles on stainless steel and polyethylene mesh. ζ-potential of cotton and clay particles in ethanol aqueous solution was measured by electrophoresis of clay particles and electroosmosis of cotton cloth, respectively. Hamaker constants were obtained from surface and interfacial tension of n-hexane in ethanol solution. Minimal detergency observed in 60% ethanol aqueous solution could not be explained based on ζ-potential and Hamaker constants. Minimal penetration velocity into clay particles in a glass column was noted 60% ethanol solution, which is in agreement with detergency of clay particles in cotton in ethanol aqueous solution.
