Abstract : Previous work with hard surfactants on the application of dimensional analysis to detergency correlation is further validated by the physiocochemical and soil removal data of systems in which the surfactants were biodegradable, commercial nonionics of the ethoxylated alkylphenol, primary alcohol, and secondary alcohol types. The fact that only eleven soil-surfactant systems gave 90-100% soil removals of the forty-two studied is attributed to the relatively low ethylene oxide (EO) mol ratios of the surfactants. It is postulated that the intrinsic detergency of the surfactants at 180F. is related to (EO) content (highe HLB and/or incsed solubility). (Author)
