Abstract: We tried an investigation into the actual consumers conditions on the use of detergents as the basic data to diminish the usage of kitchen detergents and the amount of remained surfactants to tablewares. 1) About 3/4 of the examinees use undiluted kitchen detergents to wash tablewares. 2) The ways to rinse the tablewares differ among the ages of the examinees, and the way of persons in twenties was the worst in remaining surfactants on the tablewares. The best was that by persons in thirties. 3) The remained surfactant by the one-person household is larger than that by the relatives household. 4) The remained surfactant after washing of tablewares by persons with chidren is less than that by persons without children, and especially, that by the persons with infants is the least. 5) In the ways of rinsing, the way using sponge is rather effective to remove the surfactant attached to the plastic dishes. It is also significant to remove attached surfactant on dishes by dipping the washed dishes in water during rinsing other dishes. 6) People who wash dishes roughly tend to remain rather high amount of surfactant on dishes than those who wash dishes carefully. It is remarkable that the gross amount of surfactants by 13% of examinees was over 0.2 ppm which is the maximum permissible amount of anion surfactants of city water.
