Summary of the Invention

Problems to be Solved by the Invention

[0004] As a function of changing the appearance of hair in a hair styling composition, in addition to imparting gloss as shown in Patent Document 1 above, there is a demand for imparting a matte appearance to hair (an appearance without hair gloss and with a dull look).

[0005] In order to make the above demand realizable, a white pigment may be used as a component to be blended in a hair styling composition. However, in a hair styling composition containing a white pigment, the hair styling composition may remain on the skin such as the palm after hair styling, resulting in a conspicuous state where the skin looks white on the appearance (skin whitening), and there are problems such as the need to wipe off the whitened skin area or to wash it thoroughly.

[0006] In view of the above problems, an object of the present invention is to provide a hair styling composition capable of imparting a matte appearance to hair (an appearance without gloss and with a dull look) and suppressing whitening of the skin when using the hair styling composition. Another object of the present invention is to provide a hair styling method using the above hair styling composition.

[0008] That is, the hair styling emulsion composition of the present invention is (A) a white pigment, (B) an oil that is liquid at 25°C with a kinematic viscosity of 20 mm 2 / s or less, and (C) an oil that is solid at 25°C.

[0009] From the viewpoint of improving the smoothness during hair styling, the hair styling emulsion composition of the present invention is preferably one in which the blending amount of (D) inorganic powder is 0.5% by mass or less, or (D) inorganic powder is not blended.

[0010] The hair styling emulsion composition of the present invention, for example, the above (B) oil that is liquid at 25°C with a kinematic viscosity of 20 mm 2 / s or less is one or more selected from hydrocarbon oils and / or silicone oils.

[0011] The hair styling emulsion composition of the present invention, for example, the above (C) oil that is solid at 25°C is a hydrocarbon that is solid at 25°C and / or a wax that is solid at 25°C.

[0012] The hair styling emulsified composition of the present invention is preferably one containing one or more selected from, for example, nonionic surfactants, anionic surfactants, and polymer emulsifiers, from the viewpoint of enhancing storage stability by further improving the dispersibility of the emulsion particles of the hair styling composition.

[0074] (Evaluation method for matting feeling of hair) Using 1 g of each hair styling emulsified composition of Examples 1 to 3 and Comparative Examples 1 to 3, the hair of the evaluation wig (a model wig manufactured by Regina Co., Ltd. with the hair length adjusted to about 10 cm) was styled, and the "matting feeling of hair" (an appearance where the hair has no gloss and looks dull) after styling was evaluated. The evaluation was determined by the consensus of two panelists who routinely evaluate hair styling compositions according to the following evaluation criteria as either "〇", "equivalent", or "×".

[0075] (Evaluation criteria for matting feeling of hair) 〇: Superior to the reference hair styling emulsified composition in terms of the matting feeling of hair (superior in appearance where the hair has no gloss and looks dull compared to the reference hair styling emulsified composition). Equivalent: The matting feeling of hair is equivalent to that of the reference hair styling emulsified composition (equivalent in appearance where the hair has no gloss and looks dull compared to the reference hair styling emulsified composition). ×: Inferior to the reference hair styling emulsified composition in terms of the matting feeling of hair (inferior in appearance where the hair has no gloss and looks dull compared to the reference hair styling emulsified composition).

[0076] (Method for evaluating suppression of whitening) For each of the hair styling emulsified compositions of Examples 1 to 3 and Comparative Examples 1 to 3, 0.5 g was taken on the palm of the hand. After thinly spreading the hair styling emulsified composition on the palm, the state of the whiteness of the palm was visually evaluated. The evaluation was judged by the consensus of two panelists who routinely evaluate hair styling compositions according to the following evaluation criteria as either "〇", "equivalent", or "×".

[0077] (Evaluation criteria for suppression of whitening) 〇: Compared with the reference hair styling emulsified composition, whitening of the palm is suppressed (the palm does not become whiter than the reference hair styling emulsified composition). Equivalent: Compared with the reference hair styling emulsified composition, the whitening of the palm is equivalent (the state of the whiteness of the palm is equivalent to that of the reference hair styling emulsified composition). ×: Compared with the reference hair styling emulsified composition, whitening of the palm is not suppressed (the palm becomes whiter than the reference hair styling emulsified composition).

[0078] (Method for evaluating hair styling property) Using 1 g of each of the hair styling emulsified compositions of Examples 1 to 3 and Comparative Examples 1 to 3, the hair of an evaluation wig (a model wig manufactured by Regina Co., Ltd. with the hair length adjusted to about 10 cm) was styled, and the "hair styling property" was evaluated using the lift from the root and the cohesion of the hair tips as indices. The evaluation was judged by the consensus of four panelists who routinely evaluate hair styling compositions according to the following evaluation criteria as either "〇", "equivalent", or "×".

[0079] (Evaluation criteria for hair styling property) 〇: It is evaluated that the hair styling property (lift from the root and cohesion of the hair tips) is superior compared to the reference hair styling emulsified composition. Equivalent: It is evaluated that the hair styling property (lift from the root and cohesion of the hair tips) is equivalent compared to the reference hair styling emulsified composition. ×: It is evaluated that the hair styling property (lift from the root and cohesion of the hair tips) is inferior compared to the reference hair styling emulsified composition.

[0080] (Evaluation results) The evaluation results of each hair styling emulsion composition are shown in Tables 1 and 2 below.

[0081] (Evaluation results of Examples 1 and 2 and Comparative Examples 1 and 2) The evaluation results of the hair styling emulsion compositions of Examples 1 and 2 and Comparative Examples 1 and 2 are shown in Table 1 below together with each compounding component. The hair styling emulsion composition of Comparative Example 1 was used as the evaluation criterion.

[0082]

Table 1

[0083] From the results shown in Table 1, it can be seen that the hair styling emulsion compositions of Examples 1 and 2 containing the oil which is liquid at 25°C and has a kinematic viscosity of 20 mm 2 / s or less as the component (B) are superior in suppressing white flocculation compared to the hair styling emulsion composition of Comparative Example 1 in which the component (B) is not contained. Also, it can be seen that the hair styling emulsion composition of Comparative Example 2 containing heavy fluid isoparaffin (having a kinematic viscosity greater than 20 mm 2 / s) which does not correspond to the component (B) is equivalent in suppressing white flocculation compared to the hair styling emulsion composition of Comparative Example 1 in which the component (B) is not contained, but is inferior in the mat feeling of the hair and hair styling property. Therefore, from the results shown in Table 1, it can be seen that by using the oil (component (B)) which is liquid at 25°C and has a kinematic viscosity of 20 mm 2 / s or less, excellent suppression of white flocculation can be achieved.

[0084] (Evaluation results of Examples 1 and 3 and Comparative Example 3) The evaluation results of the hair styling emulsion compositions of Examples 1 and 3 and Comparative Example 3 are shown in Table 2 below together with each compounding component. The hair styling emulsion composition of Comparative Example 3 was used as the evaluation criterion.

[0085]

Table 2

[0086] From the results shown in Table 2, it can be seen that the hair styling emulsified compositions of Examples 1 and 3 containing the white pigment as the (A) component have the same suppression of white flotation as the hair styling emulsified composition of Comparative Example 3 without the (A) component, but are excellent in the matte feeling of the hair. Therefore, it can be understood that the hair styling emulsified compositions of Examples 1 and 3 can achieve the same suppression of white flotation as Comparative Example 3 without the white pigment, despite containing the white pigment.

[0087] (Evaluation of Examples 1 and 4) Using the hair styling emulsified compositions of Examples 1 and 4 produced above, "suppression of white flotation" and "matte feeling of hair" were evaluated in the same manner as in Tables 1 and 2 above. Also, "ease of combing during hair styling" was evaluated by the evaluation method shown below.

[0088] (Evaluation method for ease of combing during hair styling) Using 1 g of each of the hair styling emulsified compositions of Examples 1 and 4, "ease of combing during hair styling" was evaluated using the ease of combing the hair during hair styling of a wig for evaluation (a model wig manufactured by Regina Co., Ltd. with the hair length adjusted to about 10 cm) as an index. The evaluation was determined by the consensus of 4 panelists who routinely evaluate hair styling emulsified compositions according to the following evaluation criteria as either "〇", "equivalent", or "×".

[0089] (Evaluation criteria for hair styling property) ○: Evaluated as being superior in ease of combing during hair styling compared to the reference hair styling emulsified composition. Equivalent: Evaluated as having the same ease of combing during hair styling compared to the reference hair styling emulsified composition. ×: Evaluated as being inferior in ease of combing during hair styling compared to the reference hair styling emulsified composition.

[0090] (Evaluation results of Examples 1 and 4) The following Table 3 shows the evaluation results of the hair styling emulsified compositions of Examples 1 and 4 together with each compounding component. The reference for evaluation was the hair styling emulsified composition of Example 1.

[0091]

Table 3

[0092] From the results shown in Table 3, it can be seen that the hair styling emulsion composition of Example 4 containing kaolin, which is the inorganic powder as the component (D), has the same suppression of white floating and matte feeling of the hair as the hair styling emulsion composition of Example 1 without the inorganic powder, but is inferior in smoothness when styling the hair.< / ph>
