(3) Add the above (2) to the above (1), mix uniformly with a homomixer while defoaming with a vacuum pump, cool to room temperature, O of the examples and comparative examples in Tables 1 and 2 A / W emulsified cream-like whole body cleaning material was produced.

  And about the Example and comparative example of Table 1 and Table 2, familiarity with water, foaming, an emollient effect, and stability were evaluated with the following method. The results are shown in Tables 1 and 2. In addition, about what was isolate | separated immediately after manufacture, evaluation was not performed and all the description of the judgment column was set to "-".

a) Familiarity with water, 10 panelists specializing in foaming, perform a hand-use test, and in accordance with the following evaluation criteria, familiarize with the water in the table cleaning and foaming when blended with water Furthermore, the average score of the 10 people's scores was determined according to the following criteria.

<Evaluation criteria>
3 points: very good fit with water / very good foaming 2 points: good fit with water / good foaming 1 point: a little bad fit with water / a little bad foaming 0 point: bad fit with water / Bubbling is bad

<Criteria>
A: 2.5 or more ○: 1.8 or more and less than 2.5 Δ: 1.0 or more and less than 1.8 × ×: less than 1.0

b) A systemic use test was conducted by 10 panelists specializing in emollient effects, an absolute evaluation was made on the emollient effects of the cleaning materials in the table according to the following evaluation criteria, and the average score of the 10 persons was evaluated a) It was judged according to the same judgment criteria.

<Evaluation criteria>
3 points: very high emollient effect 2 points: high emollient effect 1 point: low emollient effect 0 point: little emollient effect felt

c) Three stability specialists evaluated the appearance of the cleaning materials in the table when stored at 5 ° C, 25 ° C, and 40 ° C for 3 months according to the following criteria.
<Criteria>
