EXAMPLES Examples (1 to 13) and comparative examples (1 to 4) showing specific examples of the present invention will be shown below.

In the examples, the wax removability and rinsability, which are the effects of the present invention, were evaluated. The evaluation method is as follows. Evaluation Method of Wax Removability A commercially available apple was washed with water and air-dried, and then 0.5 g of wax was adhered (bond wax: soaked in Freshguard LS-100 (manufactured by Konishi Co., Ltd.)) and air-dried again. Was used as the subject. Trigger with each cleaning agent: Model T-7700 (manufactured by Canyon Co., Ltd.), 1.6 g (4 strokes) of the test substance was sprayed onto the subject, and after rubbing by hand for 10 seconds, running water (tap water) for 30 seconds was used. Then, the feeling of "kyukyu" when rinsing was evaluated sensorily based on the following criteria. The score was the average of 5 panelists.
Here, the "squeaky" feeling refers to the feeling between the surface of the apple and the finger, and as the wax is removed, the slimy feeling disappears and the sound becomes squeaky. Rinseability evaluation method Using the same trigger as for wax removability, 1.2 g (3 strokes) of each cleaning agent was sprayed on a commercially available broccoli, left for 10 seconds, and then rinsed with tap water (2 l). Do it for 20 seconds. Repeat this operation by replacing tap water until no bubbles are observed in the washing tub,
Evaluation is based on the number of times tap water is replaced. The score was the average of 5 panelists.
