Description

  The present invention relates to an emulsified composition for hairdressing. In addition, the room temperature in this invention represents the temperature range of 1-30 degreeC.

  Conventionally, hair emulsifying compositions such as hair waxes and hair creams are provided with solid oil components such as waxes and hydrocarbons at room temperature in order to impart hair styling properties such as “start-up”, “combine”, and “hold”. Is blended. However, when a large amount of solid oil is blended at room temperature, excellent hair styling properties can be obtained, but on the other hand, there is a problem that it is difficult to obtain a natural luster feeling because the oily glare is conspicuous. Moreover, since many oils are mix | blended, there also exists a problem that the washing off from hair is bad and oil remains in the hair after hair washing.

  Up to now, attempts have been made to impart a natural gloss feeling while maintaining hairdressing properties. For example, a hair styling agent (see Patent Document 1) containing waxes, a specific water-soluble polymer, fluid oil, and water, waxes, a pasty oil agent, and a polyethylene glycol having a specific polymerization degree A hairdressing material (see Patent Document 2) and the like have been proposed. However, although these attempts can give a natural luster to some extent, there is a problem that the hair is poorly washed off during hair washing.

  Attempts have also been made to improve washing off hair. For example, hair styling containing a specific liquid oil, volatile liquid oil, waxes, and water has been proposed (see Patent Document 3). However, there is a problem that, based on such an attempt, washing out from hair can be improved to some extent, but it is difficult to obtain excellent hair-styling properties peculiar to solid oil at room temperature. There is also a problem of inferior natural luster.

(Sample preparation 1)
According to the composition described in Table 1 and Table 2, each emulsion composition for hairdressing of Examples 1-4 (However, Example 3 is a reference example) and Comparative Examples 1-4 is prepared according to a conventional method, It used for 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. In addition, Comparative Example 4 is not an emulsion composition.

(Test Example 1: Evaluation of hair styling)
Each of the samples obtained in the examples and comparative examples was subjected to hair styling using wigs (Lesson Mannequin: manufactured by Eucalyptus Japan) by 20 evaluation panels, and the hair styling was subjected to sensory evaluation according to the following evaluation criteria.
The evaluation of hair styling was evaluated comprehensively with respect to “power to raise” the hair, “power to gather” the raised hair, and “force to hold” the collected hair.

<Evaluation criteria for hair styling>
○: 16 or more people out of 20 have excellent hair styling △: 10 to 15 out of 20 have excellent hair styling ×: 9 or fewer out of 20 have excellent hair styling

(Test Example 2: Evaluation of glossiness)
After the evaluation of Test Example 1, the same evaluation panel was used to look at the hair that was separated from the wig by 0.5 m, and the visual gloss was visually evaluated according to the following evaluation criteria.

<Evaluation criteria for glossiness>
○: More than 16 out of 20 people have no glare and natural luster is added. Δ: 10 to 15 out of 20 people have no glare and natural luster is given. Answer x: Nine out of 20 people answered that there was no glare and natural luster was given.

(Test Example 3: Evaluation of washing off from hair)
One hour after the evaluation of Test Example 2, the wig was shampooed with shampoo (trade name LUCIDO Shampoo, Mandom) using the same evaluation panel, and the hair was washed off with lukewarm water. The sensory evaluation was performed according to the following evaluation criteria.

<Evaluation criteria for wash-off>
○: More than 16 out of 20 people answered that they were washed off their hair △: 10-15 out of 20 people answered that they were washed off their hair without sticky feeling ×: 9 or less of 20 people felt that they were sticky Not wash away from hair

  From the results shown in Tables 1 and 2, it can be seen that the emulsified composition for hair styling of the examples has excellent hair styling properties, has no stickiness after hair styling, and has a natural gloss feeling. In addition, it can be seen that the emulsifying composition for hair styling of the example has a remarkably excellent effect in washing off from the hair at the time of shampooing even though many solid oils are blended at room temperature.

  On the other hand, it can be seen that Comparative Example 1 containing no component (C) is inferior in hair styling properties and washing off from the hair. Moreover, it turns out that the comparative example 2 containing the non-neutralized product is also inferior to washing off from hair. Furthermore, in Comparative Examples 3 and 4 in which the rosin esterified product was replaced, it was found that the gloss was inferior and the hair was washed off.

  Hereinafter, the formulation example of the emulsion composition for hairdressing which concerns on this invention is shown. In addition, content is mass%.
