ALTHOUGH a considerable amount of research has been devoted to the examination of detergency, little work has been done on rates of soil removal. Durham1 has commented on the need for kinetic studies in detergency research. We have examined the kinetics of detergency in a model circulation cleaning system. In this model system a detergent solution (0.03 M sodium hydroxide) is pumped from a 50-gallon tank through a short length of 1½-in. diam. pipe in a closed system. Test strips of stainless… CONTINUE READING
