Can be completed. The amount of the rinsing water is about 2/3 to 1/10 when the conventional hand washing detergent composition is used. Here, 1 part by mass of the composition indicates the concentration of the pure composition, and the above description regarding the amount of rinsing water is the washing of dishes for hand washing used in the preparation of the cleaning liquid regardless of the diluted concentration. It is shown that the foam disappears sufficiently when 3.3 to 133 parts by mass of rinsing water with respect to 1 part by mass of the pure agent composition.

  Further, as another specific hand-washing washing method, the tableware is immersed in a washing solution obtained by diluting the dishwashing composition for hand washing of the present invention with water, and then the dishes are washed by hand using a flexible material such as a sponge. Then, the washing | cleaning method of the tableware which performs rinsing using water is mentioned. The time for immersing the tableware is preferably 1 minute or more, more preferably 3 minutes or more, further preferably 5 minutes or more, still more preferably 10 minutes or more, most preferably 30 minutes or more, from the viewpoint of improving the cleanability. It is preferably 24 hours or less, more preferably 12 hours or less, still more preferably 6 hours or less, still more preferably 3 hours or less, and most preferably 1 hour or less. The total concentration of component (a), component (b), and component (c) in the cleaning liquid in which the tableware is immersed is preferably 100 ppm or more, more preferably 200 ppm or more, and preferably 3,000 ppm or less, further 2,000 ppm or less. Further, it is preferably 1,000 ppm or less from the viewpoint of high foamability and foam persistence. After completion of washing, water is added to perform rinsing. For example, in the present invention, 3.3 to 133 parts by mass of rinsing water is sufficiently foamed with respect to 1 part by mass of the dishwashing detergent composition for hand washing used in the preparation of the washing liquid. Disappears and rinsing can be completed quickly.

Using Table 1 and the following ingredients, the dishwashing composition for hand washing of the present invention can be prepared as shown in Table 1. The mass% of the compounding components in Table 1 are all numerical values based on the effective component. The composition of Table 1 is a dishwashing detergent for hand washing that exhibits rich foaming during washing and persistence of foam during washing, but disappears instantly when rinsed and is rinsed with a small amount of water.
