Description

The present invention relates to a creamy hair styling product.

Conventionally, as a hair styling agent for setting hair, a solid hair styling agent such as wax, which is excellent in re-styling property, flexibility to hair, etc., has been widely used. However, it is difficult to apply the solid hair styling product evenly to the hair.

To deal with such inconvenience, an aerosol spray hair styling agent that makes it easy to uniformly apply the hair styling agent to the entire hair has been developed (see Japanese Patent Application Laid-Open No. 2007-0996683). However, it may be difficult at room temperature to dissolve a solid oily component, which is a component that retains the setting power of hair, in a solvent in a stock solution of a hair styling product. In addition, there are cases where the oily components are precipitated and these cannot be sufficiently sprayed.

On the other hand, some hair styling products have a creamy dosage form. Such a cream-like hair styling product has an advantage that it can be easily spread and evenly applied to the hair as compared with a wax-like dosage form. The cream-like hair styling agent contains solid wax or hydrocarbon as a component that retains the setting force, and further contains an emulsifier such as a fatty acid alkali salt as a component that makes the hair styling agent cream-like (Japanese Patent Laid-Open No. 2011-102243). And Japanese Patent Application Laid-Open No. 2013-040107).

However, since the creamy hair styling product has a creamy dosage form, it is necessary to increase the amount of a component that retains the setting power, such as solid wax or hydrocarbon, in order to improve the setting power of the hair. is there. On the other hand, when the setting force of the hair is improved, the finger is easily caught on the hair after the setting, which causes a disadvantage that the finger passage is deteriorated.

Shown.

<Evaluation method>
The evaluation methods performed in Examples, Comparative Examples, and Reference Examples will be described.

(Hair setting power)
The hair setting ability was evaluated by five evaluators as the ease of hair preparation. Each evaluator was asked to evaluate either "good" than the evaluation criteria, "equivalent" to the evaluation criteria, or "bad" than the evaluation criteria. The evaluation results of the five reviewers were calculated as "good" = "1 point", "equivalent" = "0 points", and "bad" = "-1 point", and the total points were calculated.

(Hair caught (finger passage))
The catching of the hair was evaluated by five evaluators as the finger passage of the hair after setting. Each evaluator was asked to evaluate either "good" than the evaluation criteria, "equivalent" to the evaluation criteria, or "bad" than the evaluation criteria. The evaluation results of the five reviewers were calculated as "good" = "1 point", "equivalent" = "0 points", and "bad" = "-1 point", and the total points were calculated.

(Evaluation criteria)
The 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 creamy hair styling products of Examples 1 to 5, Comparative Example 1 and Reference Example were prepared with the compositions shown in Table 1 and used as a dosage form of a creamy O / W type emulsion.

With respect to the creamy hair styling products of Examples 1 to 5, Comparative Example 1 and Reference Example, the hair setting force and the hair catching were evaluated. The results are shown in Table 1. The "comprehensive evaluation" in Table 1 is an added value of the score of "hair setting force" and the score of "hair catching (finger passage) after setting".

Here, (C14-18) in "alkyl ethylhexanoate (C14-18)" in Table 1 means that the alkyl has 14 to 18 carbon atoms.
(10EO) and (6EO) in "Polyoxyethylene cetyl ether (10EO)" and "Polyoxyethylenecetyl ether (6EO)" are the average addition of ethylene oxide, respectively. It means that the number of moles is "10" and "6".
"A total of 100" in the column of purified water means that the amount of purified water was added to each component other than purified water blended in the creamy hair styling product to make 100% by mass. There is.

As is clear from Table 1, the creamy hair styling products of Examples 1 to 5 have a slightly lower evaluation of catching (finger passage) than the creamy hair styling products of Comparative Example 1 which is the evaluation standard, but the setting force. The overall evaluation was positive because the evaluation was excellent.

Here, the creamy hair styling products of Examples 1 to 5 and the creamy hair styling products of Comparative Example 1 have the same amount of the component (A), but the creamy hair styling products of Examples 1 to 5 have the same amount. While the component (E) is contained, the creamy hair styling product of Comparative Example 1 does not contain the component (E). That is, in the creamy hair styling products of Examples 1 to 5, by blending the component (E), a suitable setting force can be secured even when the blending amount of the component (A) is small.

Further, the creamy hair styling products of Examples 1 to 5 are set as compared with the creamy hair styling products 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 power was slightly inferior, the evaluation of catching (finger passage) was excellent, so it was superior in the overall evaluation. That is, the creamy hair styling products of Examples 1 to 5 contain the component (E), so that the amount of the component (A) is tripled even though the amount of the component (A) is small. At the same time as ensuring a setting force comparable to that of a certain reference example, catching is suppressed and it is excellent for finger passage.

<Examples 6 to 9>
The creamy hair styling products of Examples 6 to 9 were prepared with the compositions shown in Table 2 and used as a dosage form of a creamy O / W type emulsion.
For the creamy hair styling products of Examples 6 to 9, the setting power of the hair and the catching of the hair were evaluated. The results are shown in Table 2. The "comprehensive evaluation" in Table 2 is an added value of the score of "hair setting force" and the score of "hair catching (finger passage) after setting".

As is clear from Table 2, the creamy hair styling products of Examples 7 to 9 had the same or higher overall evaluation as the creamy hair styling products of Example 6 which was the evaluation standard .
