Molecular Origin of ?kyu-kyu? in Detergency: Interaction of Surfactants with the Stratum Corneum model
Abstract: In the context of dishwashing, the acoustic emissions from the physical contact of the human fingertip across a wet lubricated surface (or dish) are defined by the Japanese term, ?kyu-kyu?. These ?kyu-kyu? or squeaking sounds, indicative of customer satisfaction of a cleaned surface, have their origin in a physical phenomenon known as stick-slip friction. We hypothesize that this stick-slip, facilitated by the presence of a detergent, is caused in part by disruption of the surfactant bilayer absorbed to the contacting surface as rinsing occurs. Here, continuing on previous work in collaboration with Procter & Gamble, we propose a neutron reflectivity (NR) study of a model stratum corneum (SC) lipid monolayer and its interaction with common surfactants. The surfactants, SDS and DDAO (dodecyldimethylamine oxide) are analogues of the surfactants used in P&G formulation. The SC lipid monolayer comprises equimolar mixtures of ceramide N-lignoceroyl-D-erythro-sphingosine (Cer24NS)/ free fatty acid (FFA)/ cholesterol (Chol). The results will complement our direct measurement of friction between skin-mimics and a contacting surface, mediated by mixed surfactant systems.
