Description

  The present invention relates to a creamy hair styling agent.

  2. Description of the Related Art Conventionally, as a hair styling agent for setting hair, solid hair styling agents such as waxes having excellent hair styling properties, flexibility to hair, and the like have been widely used. However, it is difficult to apply the solid hair preparation uniformly to the hair.

  For such inconvenience, an aerosol spray hair styling agent that can easily apply the hair styling agent uniformly to the entire hair has been developed (see Japanese Patent Application Laid-Open No. 2007-099683). However, it may be difficult at room temperature to dissolve a solid oily component, which is a component that maintains hair setting power, in a solvent in the hairdressing agent stock solution. Moreover, when oily components precipitate, these may not be sprayed fully.

  On the other hand, some hairdressing agents have a creamy form. Such a cream-like hair styling agent has the advantage that it is easy to extend compared to a wax-like dosage form and can be applied uniformly to the hair. The cream-type hair styling agent contains solid wax or hydrocarbon as a component that retains setting power, and further contains an emulsifier such as a fatty acid alkali salt as a component that makes the hair styling agent creamy (Japanese Patent Laid-Open No. 2011-102243). And JP 2013-040107 A).

  However, in creamy hair styling agents, since the dosage form is creamy, it is necessary to increase the blending amount of ingredients that retain the setting power such as solid wax or hydrocarbons in order to improve the hair setting power. is there. On the other hand, when the setting power of the hair is improved, a finger is easily caught on the hair after setting, resulting in inconvenience that the finger passage is deteriorated.

<Evaluation method>
The evaluation methods performed in the examples, comparative examples, and reference examples will be described.

(Hair setting power)
The hair setting power was evaluated by five evaluators as the ease of hair preparation. Each evaluator was asked to evaluate either “good” than the evaluation standard, “equivalent” to the evaluation standard, or “bad” than the evaluation standard. The evaluation results of five reviewers were calculated as the total score, with “good” = “1 point”, “equivalent” = “0 point”, and “bad” = “− 1 point”.

(Hook of hair (as per finger))
The hair catch was evaluated by five evaluators as the finger of the hair after setting. Each evaluator was asked to evaluate either “good” than the evaluation standard, “equivalent” to the evaluation standard, or “bad” than the evaluation standard. The evaluation results of five reviewers were calculated as the total score, with “good” = “1 point”, “equivalent” = “0 point”, and “bad” = “− 1 point”.

(Lightness of styling)
The lightness of styling was evaluated by five evaluators as the feeling of hair floating after setting. Each evaluator was asked to evaluate either “good” than the evaluation standard, “equivalent” to the evaluation standard, or “bad” than the evaluation standard. The evaluation results of five reviewers were calculated as the total score, with “good” = “1 point”, “equivalent” = “0 point”, and “bad” = “− 1 point”.
In addition, about Examples 1-5, the comparative example 1, and the reference example, the evaluation of the lightness of styling is not performed.

(Evaluation criteria)
Evaluation criteria are Comparative Example 1 for Examples 1 to 5, Comparative Example 1 and Reference Example, and Example 6 for Examples 6 to 9.

<Examples 1 to 5, Comparative Example 1 and Reference Example>
The cream-type hair styling agents of Examples 1 to 5, Comparative Example 1 and Reference Example were prepared with the compositions shown in Table 1 to obtain a cream O / W type emulsion dosage form.

  About the cream-type hairdressing agent of Examples 1-5, the comparative example 1, and the reference example, the set power of hair and the catch of hair were evaluated. The results are shown in Table 1. “Comprehensive evaluation” in Table 1 is an added value of the score of “hair setting force” and the score of “hair catch after setting (as per finger)”.

Here, “C14-18” in “alkyl ethylhexanoate (C14-18)” in Table 1 means that the alkyl has 14 to 18 carbon atoms.
“10E.O.” and “6E.O.” in “polyoxyethylene cetyl ether (10E.O.)” and “polyoxyethylene cetyl ether (6E.O.)” mean the average addition of ethylene oxide, respectively. It means that the number of moles is “10” and “6”.
The “100 in total” in the column of purified water means that the amount of purified water is added to each component other than purified water blended in the cream hairdressing agent so that the total amount becomes 100% by mass. Yes.

  As is clear from Table 1, the cream-type hair styling agents of Examples 1 to 5 have a slightly lower evaluation of hooking (as per finger) than the cream-type hair styling agent of Comparative Example 1 which is an evaluation standard, but the setting power Since the evaluation of is excellent, the overall evaluation is positive.

  Here, the cream-type hair styling agents of Examples 1 to 5 and the cream-type hair styling agent of Comparative Example 1 have the same amount of component (A), but the cream-type hair styling agents of Examples 1 to 5 are the same. While the component (E) is blended, the cream hairdressing agent of Comparative Example 1 is not blended with the component (E). That is, the cream-type hairdressing agents of Examples 1 to 5 can ensure a suitable setting force even when the blending amount of the component (A) is small by blending the component (E).

  Moreover, the cream type hairdressing agents of Examples 1 to 5 are set in comparison with the cream type hairdressing agent of the reference example in which the blending amount of the component (A) exceeds 5% by mass and the component (E) is not blended. Although the evaluation of force was slightly inferior, the evaluation of catch (as per finger) was excellent, so it was superior in overall evaluation. That is, the cream-type hair styling agents of Examples 1 to 5 are blended with the component (E), so that the blending amount of the component (A) is three times despite the small blending amount of the component (A). A setting power comparable to that of a reference example can be secured, and at the same time, the catch is suppressed and the finger is excellent.

<Examples 6 to 9>
The cream-like hair styling agents of Examples 6 to 9 were prepared with the compositions shown in Table 2 to obtain a cream O / W emulsion formulation.
For the cream-like hair styling agents of Examples 6 to 9, the hair setting power, the hair catching, and the lightness of styling were evaluated. The results are shown in Table 2. “Comprehensive evaluation” in Table 2 is the added value of “Hair setting power”, “Hook of hair after setting (as per finger)” and “Lightness of styling after setting” is there.

  As is clear from Table 2, the cream-like hair styling agents of Examples 7 and 8 had an overall evaluation equivalent to or higher than that of the cream-like hair styling agent of Example 6 as an evaluation standard. On the other hand, the cream-like hair styling agent of Example 9 was inferior in overall evaluation as compared with the cream-like hair styling agent of Example 6 which is the evaluation standard.

Here, the cream-like hair styling agent of Example 9 satisfies the condition of the above mathematical formula 2, but satisfies the condition of the mathematical formula 3 because the blending amount of the component (A) and the component (B) is large. Absent. Therefore, it can be understood that the comprehensive evaluation of the three items of setting force, catching and styling becomes excellent by satisfying the conditions of Equation 2 and Equation 3.
