In Table 1 and Table 2 below, the amount of each component is shown in% so that the total amount of the hairdressing agent is 100%, but the% is mass%, and the display of% is also shown. Omitted and displayed only as a numerical value representing the blending amount. In this example, “%” is based on mass (mass%) unless otherwise specified.

Examples 1-8 and Comparative Examples 1-8
The hair styling agents of Examples 1-8 and Comparative Examples 1-8 were prepared with the compositions shown in Tables 1 and 2, and the following evaluations were performed.

<Evaluation of gloss like wet hair after styling with hair styling agent>
Each of the five professional evaluators evaluated the wetness of the hair after applying the hair styling agent: 1 g to the subject's hair (dried hair). Compared with the case where the hairdressing agent of Comparative Example 1 was used, the score was given according to the following evaluation criteria.

[Evaluation criteria for wet gloss of hair after styling]
Better than when using the hair styling agent of Comparative Example 1: 2 points
Equivalent to using the hair styling agent of Comparative Example 1: 1 point
Worse than when the hair styling agent of Comparative Example 1 was used: 0 points.

  The total score of all evaluators for each hairdressing agent is totaled, 8 to 10 points for “◎”, 6 to 7 points for “◯”, 5 points for “△”, 4 points or less. Was classified as “×”.

  The evaluation results, the appearance of the hairdressing agent by visual observation, and the viscosity at 25 ° C. of each hairdressing agent measured by the above method are shown in Tables 1 and 2.

  In Tables 1 and 2, “with a total of 100” in the column of water means that the total amount of each component other than water constituting the hairdressing agent is added to the amount of water to be 100%. I mean. Further, in Tables 1 and 2, “POE” in “Tristearic acid POE (20) sorbitan”, “POE (10) behenyl ether”, “POE (20) hydrogenated castor oil” and the numerical values in parentheses thereafter are: This is the same as in the specific examples of the polyoxyethylene alkyl ether phosphoric acid. Furthermore, “-” in the column of “Viscosity at 25 ° C.” in Tables 1 and 2 means that viscosity measurement was impossible.

  As shown in Table 1 and Table 2, the components (A) to (D) are blended, and the total amount of the blending amount of (A) component and (B) component, and (C) component Compared to when using the hairdressing agent of Comparative Example 1 in which the hair of the hairdressing agent of Examples 1 to 8 in which the blending amount is appropriate is not blended with the polyoxyethylene sorbit fatty acid ester as the component (B), The wet luster was good. Furthermore, the hairdressing agents of Examples 2 and 4-7, in which glycerin (E) component is blended and the blending amount of liquid oil (C) component is limited to some extent, (E) component is not blended. Transparency was higher than the hair styling agents of Examples 1 and 8 and the hair styling agent of Example 3 with a large amount of component (C). The hair styling agent of Example 8 had a low viscosity at 25 ° C. due to the action of 1,3-butylene glycol, and further decreased at a high temperature of about 50 ° C.

  In contrast, the hair styling agent of Comparative Example 2 in which the blending amount of component (C) is too small, the blending amount of polyoxyethylene alkyl ether phosphoric acid or its salt as component (A) and polyoxyethylene as component (B) The hair styling agent of Comparative Example 3 in which the total amount with the blending amount of sorbite fatty acid ester is too small, the hair styling agent of Comparative Example 4 in which (C) component is not blended, and Comparative Example 5 in which (A) component is not blended. In all hairdressing agents, the components were separated, and the viscosity was so low that it was liquid and viscosity measurement was impossible. And the hairdressing agents of Comparative Examples 2-5 were inferior in luster as if the hair after hairdressing was wet. In addition, stickiness occurred in the hair to which the hairdressing agent of Comparative Example 5 was applied, and when the hairstyling agent of Comparative Example 5 was left at a high temperature of about 50 ° C., separation of the blended components occurred.

  Further, the hair styling agents of Comparative Examples 6 to 8 are nonionic surfactants having the same HLB value as the tetraoleic acid POE (30) sorbit used as the component (B) in the hair styling agents of the examples [(B). In this example, the nonionic surfactant other than the component] was blended in place of the component (B), but the hair that had been adjusted with these had poor wet luster.
