[0016]

EXAMPLES The present invention will now be described in detail with reference to examples, but the present invention is not limited thereto.

A cleansing composition was prepared according to the formulations shown in the table below for Examples 1 and 2 and Comparative Example 1, and the caliber was 2.5 m.
m, and a discharge amount of 1.5 ml was filled in a pump type container having a nozzle discharge port to obtain a cleansing composition. Then, the following methods were used to evaluate the evaluation items of usability at the time of discharge from the pump type container, feeling of use of the cleansing composition, and ease of washing with water.

[0018]

[Table 1]

The above-mentioned examples for the present invention were tested for use by female panelists. The usage test was carried out on 20 panelists, each of Example 1, Example 2 and Comparative Example 1
Was used for 2 weeks. Each panel has 5 levels of convenience in use when discharging the container (evaluation based on the presence or absence of dripping and splashing), feeling of use of the cleansing composition (evaluation of ease of application and spreadability), and ease of washing with water ( +
2: Very good, +1: Good, 0: Normal, -1: Bad,
-2: Very bad). Furthermore, judgment was made based on the following criteria from the average value of the evaluation points. 1.0 point or more: ◎ 0 or more and less than 1.0 point: ○ Less than 0 point Minus point: ×

From these results, the liquid oil-based cleansing agent filled in the pump container was 300 to 3000 mPa · s.
It can be seen that having an appropriate viscosity makes it excellent in usability during discharge and usability during cleansing.
