Description

  The present invention relates to a hair styling agent.

  In order to maintain the hairstyle, various types of hairdressing agents have been put into practical use. Examples of the hairdressing agent dosage form include hair spray, hair mist, mousse, foam, hair gel, set lotion, hair cream, hair wax and the like. Among these hair styling agents, hair creams, hair waxes, and the like utilize the hardness of solid wax or solid hydrocarbon for hair styling power (see JP 2011-168508 A).

  However, since hair cream and the like obtain hair styling power with solid wax or solid hydrocarbon, there is a disadvantage that the hair setting power is weak. Therefore, it is conceivable to increase the blending amount of solid wax or solid hydrocarbon in order to improve the setting power of the hair, but in that case, there is a disadvantage that the sticky feeling of the hair after setting increases. As described above, it is difficult to achieve both improvement of hair setting power and suppression of stickiness.

JP 2011-168508 A

  The present invention has been made in view of the above disadvantages, and an object of the present invention is to provide a hair styling agent capable of suppressing the stickiness of hair after setting while sufficiently securing the hair setting force.

  As a result of intensive studies to solve the above problems, the present inventor has found that the above problems can be solved by blending a modified corn starch in a hair styling agent blended with solid wax or hydrocarbon. The invention has been completed.

That is, the present invention

(B) liquid ester oil,
(C) volatile silicone,
(D) a nonionic surfactant,
A hair styling agent comprising (E) modified corn starch and (F) water.

  According to the hair styling agent, by adding the modified corn starch, it becomes possible to suppress the stickiness of the hair after setting while sufficiently securing the setting power of the hair.

Only numerical values are shown.

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

(Sticky)
The stickiness was evaluated by five evaluators on the stickiness of the hair after setting. For each evaluator, as a result of confirming stickiness by hand, the stickiness is “suppressed” than the evaluation standard, the stickiness is equivalent to the evaluation standard, or the stickiness is worse than the evaluation standard. "Evaluated by either Regarding the evaluation results of 5 reviewers, “stickiness is suppressed” = “1 point”, “equivalent” = “0 point”, “stickiness is getting worse” = “− 1 point” Calculated as the total score.

(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 “easier to prepare” than the evaluation standard, “equivalent” to the evaluation standard, or “harder to prepare” than the evaluation standard. The evaluation results of five reviewers were calculated as “easy to arrange” = “1 point”, “equivalent” = “0 point”, “difficult to prepare” = “− 1 point”, and the total score was calculated.

(Evaluation criteria)
The evaluation criteria are Comparative Example 2 for Examples 1 and 2 and Comparative Examples 1 and 2, and Example 3 for Examples 3-7.

<Examples 1 and 2 and Comparative Examples 1 and 2>
The hair styling agents of Examples 1 and 2 and Comparative Examples 1 and 2 were prepared as cream O / W emulsions with the compositions shown in Table 1. In Example 1, the amount of component (A) is 10% by mass or less, and in Example 2 and Comparative Examples 1 and 2, the amount of component (A) is more than 10% by mass.

  About the hairdressing agents of Examples 1 and 2 and Comparative Examples 1 and 2, the stickiness after setting the hair and the setting power of the hair were evaluated. The results are shown in Table 1.

Here, (20E.O.) and (5.5E.O.) in “Polyoxyethylene cetyl ether (20E.O.)” and “Polyoxyethylene cetyl ether (5.5E.O.)” in Table 1 are used. ) Means that the average added moles of ethylene oxide are “20” and “5.5”, respectively.
“Set to 100” 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 hairdressing agent so that the total amount becomes 100% by mass.

As is apparent from Table 1, the hair styling agent of Example 1 was markedly suppressed in terms of the stickiness of the hair after setting compared to the hair styling agent of Comparative Example 2 which is the evaluation standard.
The hair styling agent of Example 2 was superior to the hair styling agent of Comparative Example 2 as an evaluation standard, and was excellent in setting power of the hair, and the stickiness after setting was suppressed. As a result, the overall evaluation was positive.
The hair styling agent of Comparative Example 1 was excellent in hair setting power, but the stickiness of the hair after setting was deteriorated.

  Here, while the hair styling agents of Examples 1 and 2 are blended with modified corn starch as component (E), the hair styling agents of Comparative Examples 1 and 2 are not blended with modified corn starch. In the hair styling agent of Example 1, instead of the modified corn starch, polyvinyl pyrrolidone which is the same nonionic polymer as the modified corn starch is blended. That is, the hair styling agents of Examples 1 and 2 can suppress the stickiness of the hair after setting by blending the modified corn starch, and the stickiness suppressing effect is superior to polyvinyl pyrrolidone which is the same nonionic polymer. It is inferred.

  Moreover, although the compounding quantity of (A) component exceeds 10 mass% of the hairdressing agent of Example 2 and Comparative Examples 1 and 2, the hairstyling agent of Example 2 has the least stickiness of the hair after setting. It was. That is, the hair styling agent of Example 2 resulted in suppression of stickiness of the hair after setting despite the large amount of component (A).

<Examples 3 to 7>
The hair styling agents of Examples 3 to 7 were prepared as cream O / W emulsions with the composition shown in Table 2.

  About the hairdressing agents of Examples 3 to 7, the stickiness after setting the hair and the setting power of the hair were evaluated. The results are shown in Table 2.

  Here, “C14-18” in “alkyl ethylhexanoate (C14-18)” in Table 2 means that the alkyl has 14 to 18 carbon atoms. Others are the same as in Table 1.

As is apparent from Table 2, the hair styling agent of Example 4 is slightly inferior to the hair stickiness after setting compared to the hair styling agent of Example 3 which is an evaluation standard, but has excellent setting power and comprehensive evaluation. Became a plus.
The hair styling agent of Example 5 had the same stickiness of the hair after setting as compared with the hair styling agent of Example 3 which is an evaluation standard, but the setting power was inferior and the overall evaluation was negative. This is considered to be because the blending amount of the component (A) that greatly contributes to the setting force is smaller than that of the hair styling agent of Example 3. For this reason, it is considered preferable to increase the amount of component (A), specifically 10% by mass or more.
Compared with the hair styling agent of Example 3, which is the evaluation standard, the hair styling agent of Example 6 had lower hair stickiness and setting power after setting, and the overall evaluation was negative. Therefore, it is considered preferable that the blending amount of the component (B) is small, specifically, 5% by mass or less.
The hair styling agent of Example 7 is superior in hair setting power to the hair styling agent of Example 3 which is an evaluation standard, but the stickiness of the hair after setting is slightly inferior. This is probably because the amount of component (C) is less than that of the hair styling agent of Example 3. Therefore, from the viewpoint of suppressing stickiness, it is considered that the blending amount of the component (C) is large, specifically, it is preferably 10% by mass or more.
