There are very moist feelings (5 points), there are (4 points), neither can be said (3 points), there is not much (2 points), and there is no (1 point). An average evaluation score of 4 or more is ◎ (highest evaluation), 3 or more and less than 4 points is ◯ (second highest evaluation), 2 or more and less than 3 points is △ (second lowest evaluation) Less than 2 points were evaluated as x (lowest evaluation).

(Measurement of viscosity)
Using a TVB-10 viscometer (manufactured by Toki Sangyo Co., Ltd.), measurement was performed under conditions of No. 3 rotor, 12 rpm, and 1 minute. However, for those whose viscosity exceeded 10,000 mPa · s, the measurement was performed again under the conditions of No. 3 rotor, 6 rpm, and 1 minute. The sample temperature was 25 ° C.

Compared to the samples of Examples 1-5. The sample (Comparative Example 3) having a higher content of nonionic surfactant than the samples of Examples 1 to 5 has an evaluation result of “rapidity of foaming” and “usability” of “x”. The evaluation result of “fineness of foam” is “Δ”, which is inferior to the samples of Examples 1 to 5. Therefore, it can be seen that the inclusion of the nonionic surfactant in an amount of 0.5% by mass to 3.0% by mass improves the foaming speed, the fineness of the foam, and the usability.

(Evaluation on types of nonionic surfactants)
Comparative examples 4 to 10 in FIG. 3 are comparative examples corresponding to the examples 6 to 11 in FIG. 2. As shown in FIG. 2, Examples 6-11 differ in the HLB value of the polyoxyethylene alkyl ether which is a nonionic surfactant, and other compositions are the same. The HLB values of the polyoxyethylene alkyl ethers of Examples 6 to 11 are different from each other within the range of 16.5 to 19.5. In Examples 6 to 7, polyoxyethylene lauryl ether was used as the polyoxyethylene alkyl ether, and in Examples 8 to 11, polyoxyethylene cetyl ether was used as the polyoxyethylene alkyl ether. On the other hand, as shown in FIG. 3, Comparative Examples 4 to 6 have a lower HLB value of polyoxyethylene alkyl ether than the samples of Examples 6 to 11, and Comparative Example 7 is compared to the samples of Examples 6 to 11. The HLB value is large. In Comparative Examples 8 to 10, another nonionic surfactant is used in place of the polyoxyethylene alkyl ether.

  In contrast, as shown in FIG. 3, samples (Comparative Examples 4 to 7) in which the HLB value of the polyoxyethylene alkyl ether is out of the range of the present embodiment have an evaluation result of “speed of foaming” of “ × ”or“ Δ ”, which is inferior to the samples of Examples 6-11. The sample using the polyoxyethylene hydrogenated castor oil instead of the polyoxyethylene alkyl ether (Comparative Example 8) has an evaluation result of “bubble elasticity” of “x”, and compared with the samples of Examples 6 to 11 Inferior.
