Abstract:

Recent work at this laboratory on the application of dimensional analysis to the detergency process using commercial hard surfactants was further validated by data on twenty soil-surfactant systems in which the surfactants were commercial biodegradable nonionics. The previous validation was made more meaningful by re-calculations with CMC and surface tension values determined in this laboratory replacing the previously-used literature values of homogeneous materials. Dimensional analyses with detergency assigned the dimensions of work, ML sq. XT sq., and of force, MLT sq., as substitutes for the postulated MLMmass, Llength, Ttime could not be validated. The relevance of the variables comprising the valid dimensional analysis was enhanced by the non-validation of several dimensional analyses based on other groups of apparently critical process parameters.
