The temperature stability and the feeling of use of the above Examples 4 to 8 were evaluated. The temperature stability was evaluated in the same manner as in Examples 1 to 3. The evaluation of the feeling of use was carried out by using 20 female panelists as one group and blindly using the examples and comparative examples in each group, and sensory-evaluating the appearance, usability and skin irritation. The sensory evaluation results were "good; 5 points" and "somewhat good" for the appearance.
"4 points", "ordinary; 3 points", "slightly bad; 2 points", "poor; 1 point", usability "good; 5 points", "somewhat good; 4 points", "normal; 3 points" , "Slightly bad; 2 points",
"Poor; 1 point", for skin irritation "No irritation; 5 points", "Slightly irritation; 4 points", "Slightly irritation; 3 points", "Clearly irritation; 2 points ",
It was scored as "feeling strong irritation; 1 point" and shown as an average value of 20 persons. In addition, what replaced the polyhydric alcohol which has a 3 or more hydroxyl group in each Example with purified water was set to Comparative Example 6-Comparative Example 10, respectively. The results are summarized in Table 3.

[Table 3]

As is clear from Table 3, all the examples of the present invention showed good temperature stability, and in the use test, most of the panelists in each use group of the examples had a good appearance. It was evaluated that the usability was also good.
Further, most panelists did not feel the skin irritation, and the skin irritation was further reduced as compared with the comparative example. On the other hand, the comparative examples were all poor in temperature stability, and the appearance and usability of each comparative example use group were significantly lower than those of the example use group.
