Description

The present invention relates to an oily hair cosmetic.

BACKGROUND ART Hairdressing compositions of various properties such as liquid, gel, cream and solid are used to condition hair.

An oil-based hair styling composition containing such a solid wax tends to form relatively thick hair bundles, and therefore, when the hair is styled to stand up, the hair bundles tend to droop under their own weight. In some cases, the hairstyle cannot be maintained after a long period of time. In addition, with an oil-based hairdressing composition containing a solid wax, the hair after styling may become shiny. On the other hand, in some cases, there is a demand for a hairstyle in which relatively fine hair tufts are set up, and there is an increasing demand for a hairdressing composition capable of styling such a hairstyle. In addition, there is an increasing demand for a hairdressing composition that imparts a matte texture (mat texture) to the hair after styling, without an unnatural luster.

(Examples 1 to 32 and Comparative Examples 1 to 3)
A solid oily hair cosmetic (hair clay) having the composition shown in the table below was prepared by blending the ingredients shown in the table below (in units of % by mass). The compounding amounts in the table are indicated by pure content (unit: % by mass).

(evaluation)
Evaluation was performed as follows. All evaluations were performed by three expert panels.

(Test Example 1: Formation of a hairstyle that raises fine hair bundles (starting force, appearance of hair bundles)
Take 1.5 g of the oily hair cosmetic obtained in Examples and Comparative Examples on the palm, spread it on the palm, and then apply it evenly on the hair of a short hair wig (Lesson Mannequin, manufactured by Eucalyptus Japan). , The hair was styled by raising the hair upward from the root of the hair. The rising angle of the hair near the top of the hair wig immediately after styling was visually observed. From the angle at which the hair rises, the power to raise the hair was evaluated according to the following evaluation criteria. The above angles were 0° in the horizontal direction and 90° in the vertical direction.
In addition, the hair wig immediately after styling was visually observed and evaluated according to the following evaluation criteria.
<Evaluation Criteria for Launching Power>
◯ (Good): The angle of rising of the hair near the top of the head was 45° or more.
x (defective): The angle of rising of the hair near the top of the head was less than 45°.
<Evaluation Criteria for Appearance of Hair Twist>
◯ (Good): Hair bundles are thin and inconspicuous.
× (defective): Hair bundles are thick and conspicuous.
When both the rising force and the appearance of the hair bundle are good (O), it is judged that a hairstyle is formed in which fine hair bundles are raised.

(Test Example 2: matte texture)
The hair wigs styled in Test Example 1 were visually observed and evaluated according to the following evaluation criteria.
<Evaluation criteria for matte texture>
○ (Good): The hair lacked luster and had a matte appearance.
× (poor): The hair has a clearer gloss than the unapplied hair.

(Test Example 3: Coatability)
In Test Example 1, the spreadability on the hair when the hair was styled was evaluated according to the following evaluation criteria.
<Applicability evaluation criteria>
◯ (Good): When applied to a hair wig, the hair can be uniformly applied without feeling that fingers are caught on the hair.
x (poor): When applying to the hair wig, there is a feeling that fingers are clearly caught on the hair, and it cannot be applied evenly.

Results are shown in the table below.

As shown in the table, the oil-based hair cosmetics of Examples had excellent hair raising power, fine hair bundles, inconspicuous hair bundles, and fine hair bundles raised up. In addition, the matte texture was excellent, and the coatability was also excellent.
In Examples, the angle of rising of the hair in the vicinity of the top of the head of the hair wig set in Test Example 1 after standing for 6 hours was 45° or more. It was also excellent in the function of holding the styled hairstyle (hair style retention power).
