Description

  The present invention relates to a composition for hair. More specifically, for example, the present invention relates to a composition for hair that can be suitably used as a composition for hairdressing agents such as hair wax, hair gel, hair water, and hair foam.

  2. Description of the Related Art In recent years, cosmetics that add graceful radiance of iris color, which originates from skin cosmetics such as nail cosmetics and makeup cosmetics, are preferred. Also in styling agents, not only the gloss and gloss inherent in hair, but the beauty of appearance has been regarded as important, and there is a need for a styling agent that adds an elegant glow of iris color.

  Examples of means for imparting such graceful radiance of iris color include hair-dressing compositions containing decorative agents, hair fixatives and volatile liquid substances, cosmetics for eyes containing strip-like polymer powder, and hair. Cosmetics and the like have been proposed (see, for example, Patent Documents 1 and 2).

  However, these patent documents only describe means for fixing the brightener to the hair, and the removal of the brightener by external stimuli such as combs and hand combs, which are important in designing a styling agent. Has not been studied. Furthermore, the improvement of functionality such as hair styling retention property of the styling agent and the solution of various problems such as stickiness, stickiness, and flaking have not been achieved, and these properties cannot be satisfied.

  Therefore, it is desired to develop a composition for hair having both the fixing of a brightener that can withstand external factors and the function required for a styling agent.

  Therefore, in order to have a function inherent to the styling agent and fix the brightener to the hair, it is conceivable to solidify the hair using a film forming agent and fix the brightener.

  However, when an amount of the film-forming agent effective for fixing the brightener is used, even if the peeling of the brightener can be prevented, the hair feels worse, i.e., a feeling of stiffness occurs. The film-forming agent coated on the hair is peeled off by an external stimulus such as a comb or hand comb after setting, and white powder, so-called flaking occurs on the hair, or the film-forming agent is peeled off when the film-forming agent is peeled off. Has the disadvantage of causing.

  In order to eliminate the disadvantages inherent to styling agents such as flaking and stickiness, attempts have been made to soften the film formed by the film forming agent. For example, a set agent containing silicones as a plasticizer has been proposed. (For example, see Patent Document 3). However, if the coating is made flexible, the fixing power of the brightener to the hair is weakened, so that it is difficult to fix the coating.

  The number of resin layers in the laminate is not particularly limited, but when the number is too large, the thickness of the laminate itself is increased, and is usually about 2 to 5 layers, preferably 2 to 3 layers. It is desirable that

  As the brightener, for example, a plurality of resin films having a desired thickness are used. If necessary, a metal layer is formed on the resin film, and the resin films are laminated and integrated, and then become a predetermined size. Further, it can be produced by cutting or crushing. The integration of each resin film can be performed by, for example, heat fusion, adhesion with an adhesive, or the like.

  There is no particular limitation on the shape of the brightener. Examples of the shape include a polygon such as a quadrangle and a hexagon, a circle, a star, and other irregular shapes.

In the present invention, the size of the brightener is defined by a planar area. The plane area of the brightener means the area of one plane of the brightener.

(1) Flaking Each hair sample for testing (hair length 10 cm, width 0.8 cm, weight 1 g) left in a constant temperature and humidity chamber at 23 ° C. and 60% humidity overnight. After applying 400 μL of the hair composition obtained in each comparative example, the hair was uniformly extended with a comb. After that, the thickness of the hair bundle was made uniform and left again in a constant temperature and humidity chamber at 23 ° C. and 60% humidity for 24 hours, and then the comb was combed 10 times from the top to the bottom with a comb, The state of occurrence was visually observed.

  In addition, the evaluation of the state of occurrence of flaking was carried out by 10 expert panelists observing at a predetermined distance from the hair bundle, and flaking on the hair was evaluated according to the following evaluation criteria.

<Evaluation criteria for flaking>

(2) Stiffness Each test was performed on a test hair bundle (hair length: 10 cm, width: 8 cm, weight: 1 g) left in a constant temperature and humidity room at 23 ° C. and 60% humidity. After applying 400 μL of the hair composition obtained in Examples and Comparative Examples, the hair was evenly extended with a comb. Thereafter, the thickness of the hair bundle was made uniform, and again left in a constant temperature and humidity chamber at 23 ° C. and 60% humidity for 24 hours, and then the state of wrinkle was evaluated by sensory evaluation.

  In addition, evaluation of the presence or absence of wobbling was performed by 10 expert panelists who performed sensory evaluation by touching the hair bundle and evaluated the feeling of wobbling according to the following evaluation criteria.

<Evaluation criteria for the feeling of stiffness>

Δ: Stickiness is recognized.
X: A very stiff feeling is recognized.

(3) Dispersibility, fixability and glossiness A test hair bundle (hair length: 10 cm, width: 0.8 cm, weight: 1 g) left in a constant temperature and humidity chamber at 23 ° C. and 60% humidity overnight. Next, 400 μL of the hair composition obtained in each Example and each Comparative Example was applied, and then uniformly spread with a comb. After that, the thickness of the hair bundle is made uniform and left again in a constant temperature and humidity chamber at 23 ° C. and 60% humidity for 24 hours, and then the hair is combed 10 times continuously from top to bottom with a comb. The dispersibility, fixability and glossiness on the hair were visually observed.

  For the evaluation of the fixability and glossiness of the brightener on the hair, 10 specialist panelists observe the hair at a predetermined distance from the hair bundle to determine the dispersibility, fixability and glossiness of the brightener on the hair. Evaluation was performed according to the following evaluation criteria.

○: The brightener is dispersed and fixed on the hair, but slight peeling is also observed.
Δ: Clearly peeling of the brightener is observed.
X: A brightener is not recognized even from observation within 50 cm from a hair bundle.

<Glossy evaluation criteria>
A: Graceful shine of iris color is recognized.
○: A slight decrease in the brightness of the iris color is recognized.
(Triangle | delta): The reduction | decrease of the elegant brightness of an iris color is recognized.
X: Brightness is not observed even when observed from within 50 cm from the hair bundle.

  From the results shown in each table, the hair composition obtained in each example is clearly in contrast to those obtained in each comparative example, despite the external stress due to the comb. It can be seen that the fixing property of the brightener to the hair is excellent and the occurrence of flaking due to the peeling of the film forming agent is prevented. From this, the composition for hair obtained in each Example does not generate flaking due to external stimuli, and thus has both the suppleness of hair and the strong fixing power of the brightener to the hair.
