Description

  The present invention relates to a hair wax. The “hair wax” in the present invention is a dosage form that does not exhibit fluidity, and when the wide mouth container is filled and the container is tilted at 90 ° for 1 minute, the filled content does not sag from the wide mouth container. Say things. In addition, the room temperature in this invention represents the temperature range of 1-30 degreeC.

  In recent years, hair waxes in which waxes, hydrocarbons, and water are emulsified and filled in a wide-mouth container have become the mainstream as a hair styling agent, which has the property that hair can be freely arranged over and over again. Such a hair wax has a great feature that it has a non-flowable property.

  Among these hair waxes, from the viewpoint of hair styling properties, when a large amount of waxes or hydrocarbons are blended, the properties become waxy, so the surface of the contents filled in the wide-mouth container becomes hard. . Therefore, there is a problem that when the contents are taken out with the fingertip, the surface becomes a wax piece having a “tattered” surface, and an appropriate amount cannot be taken out easily. In addition, there is a problem in that the wax pieces on the surface of the contents spread due to daily use and it becomes difficult to take out an appropriate amount. Moreover, it is possible to make it easy to take out the contents from the wide-mouthed container by reducing the blending amount of waxes and hydrocarbons, but this measure is not preferable because it impairs the hair-styling characteristics peculiar to hair wax.

  In order to solve such problems, attempts have been made to facilitate removal from the container. Specifically, for example, a linear hydrocarbon wax having a different melting point, a branched hydrocarbon wax, a surfactant containing a linear alkyl group, water, and an emulsified hair styling having a hardness of 5 g or more ( For example, see Patent Document 1).

  However, although these attempts can improve the ease of removal from the container to some extent, there is a problem that it is difficult to obtain hair-styling characteristics peculiar to hair wax, such that hair can be freely arranged many times.

(Sample preparation 1)
According to the composition described in Table 1 and Table 2, each hair wax of Examples 1 to 3 and Comparative Examples 1 to 3 was prepared according to a conventional method, filled into a wide-mouth container, and subjected to the following evaluation. The results are shown in Table 1 and Table 2, respectively. In addition, all evaluation was implemented on the constant conditions of constant temperature and humidity of 23 degreeC and 60% of humidity.

(Test Example 1: Evaluation of breakability of contents surface)
The surface breakability (see FIG. 1B) of the contents when each sample obtained in the examples and comparative examples was traced so as to be pressed with a fingertip was evaluated according to the following evaluation criteria.

<Evaluation criteria for breakability of contents surface>
○: Breaking state due to cracks ×: Not breaking state due to cracks

(Test Example 2: Evaluation of breakability of contents)
After the evaluation of Test Example 1, the ruptured state of the contents (see FIG. 1 (c)) when stirring with a fingertip was evaluated according to the following evaluation criteria.

<Evaluation criteria for breakability of contents>
○: Easily breaks ×: Does not break

(Test Example 3: Evaluation of ease of removal)
After the evaluation of Test Example 2, the content was actually taken out by 20 sensory evaluation panels, and the ease of taking out was evaluated according to the following evaluation criteria.

<Evaluation criteria for ease of removal>
○: 16 or more out of 20 respondents can easily take out the appropriate amount. Δ: 10-15 out of 20 respondents can easily take out the appropriate amount ×: 9 out of 20 respondents have the appropriate amount Answer that it can be easily removed

(Test Example 4: Evaluation of restorability)
After the evaluation in Test Example 3, the shape of the content was left as it was overnight, and the surface state of the content over time was evaluated according to the following evaluation criteria.

<Restorability evaluation criteria>
○: The fractured portion is restored to a uniform surface state over time, and the surface of the contents is restored to a flat state. ×: There is no change in the shape of the contents (not restored)

(Test Example 5: Evaluation of re-styling properties)
20 professional panels gave each sample obtained in the examples and comparative examples to stylist hair using a wig (Lesson Mannequin: made by Eucalyptus Japan). Sensory evaluation was performed according to the following evaluation criteria.

  In addition, the evaluation of re-styling is performed by breaking the hair that has been stipulated once, performing the operation of squeezing from the tip of the hair again 10 times, and re-styling the styling shape that is clearly retained in the formed style. Evaluated as good.

<Evaluation criteria for re-styling>
○: Reply if 16 or more out of 20 are excellent in re-styling Δ: Reply if 10-15 in 20 are excellent in re-styling ×: Reply that 9 or less in 20 are excellent in re-styling
