In general washing by hand, for example, when a normal cleaning agent is used, it is generally required 5 times or more. However, in the present invention, rinsing can be completed in 3 times or less, and rinsing is performed with very little rinsing water. Can be terminated.
  • the hardness of water used for the preparation of cleaning water and / or the hardness of rinsing water is preferably 1 ° DH to 50 ° DH, more preferably 2 ° DH to 40 ° DH, more preferably from the viewpoint of cleaning power and rinsing properties.
  • a liquid detergent composition was prepared using the ingredients shown in Tables 1 to 3, and the following evaluations were performed. The results are shown in Tables 1 to 3.
  • the evaluation criteria when the entire washing liquid surface was covered with foam, the height of the foam was measured by inserting a ruler and evaluated according to the following criteria.
  • underwear was used in which 1.0 g of the adjustment oil was uniformly dropped per sheet.
