Outline of Final Research Achievements

We investigated the factors of the new detergent and clarified the following.
①In situ monitoring of detergent process in the aqueous SDS solution by the quartz crystal microbalance method was performed and the removal of solid oily soil was found to promote by the addition of amide amine oxide. In addition, the factors for enzyme reactions and a new decomposition reaction of fatty acid with a peroxidase were identified.②The washing behaviors of the soiling were clarified kinetically. The detergency of different detergent types were also investigated. An indicator detergent composition for the detergency evaluation based on nonionic surfactants was proposed. A method for testing the performance of detergents using a washing machine was also developed.
We suggested ways of using the new detergent types that are both economical and less environmentally damaging by a LCI analysis. We developed new educational materials. These introduce our novel approach to home laundering.
