The hair cosmetic composition according to the present invention applies a mixture of a first agent and a second agent to hair at the time of use. The first agent contains (A) potassium carbonate, (B) a higher alcohol, and (C) a cationic surfactant. The hair cosmetic composition is of a two-part type, but includes a composition in which the first agent and / or the second agent are further divided into a plurality of agents. The mixing amount of the first agent and the second agent at the time of use is not particularly limited, and can be appropriately determined according to the properties of the hair cosmetic composition.

The hair dye is a concept including, for example, an oxidative hair dye. The hair bleaching agent is a concept including, for example, a hair bleaching agent and a hair bleaching agent.

[Dosage form of hair cosmetic composition, viscosity of first agent and second agent, etc.]
The dosage form of the first agent and the second agent in the two-part hair cosmetic composition is not particularly limited. For example, solid, aqueous solution, dispersed liquid, emulsion, gel, foam, and cream can be mentioned. Examples of solid dosage forms include powder and tablets.

(Hair depigmenting agent)
The hair bleaching agent comprises a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and decolorizes the hair by decomposing the melanin of the hair. The hair bleaching agent is basically configured in the same manner as the oxidation hair dye except that it does not contain an oxidation dye.

(Hair destaining agent)
The hair decoloring agent is usually a multi-component type of two or more agents, and is mainly intended for hair decoloring (decomposition of dyes dyed on the hair). The difference is that an alkali agent is blended with one agent, and further, a persulfate that is a kind of alkali agent is blended as a decoloring aid.

Further, according to the present invention, a cosmetic method using the above-described hair cosmetic composition, particularly a cosmetic method using a foamed hair cosmetic composition is provided.

[Hair cosmetic supplies]
The hair cosmetic product according to the present invention is a non-aerosol foam type dosage form to be applied to hair when used, and the hair cosmetic composition to be ejected in the form of foam. Non-aerosol foamer container.

A typical example of a non-aerosol foamer container is a pump former or a squeeze foamer. The pump former is a device that presses the pump head to discharge the stored liquid (for example, the first / second mixed liquid of hair cosmetics) in the form of foam. The stored liquid is mixed with air. Then, a foam discharger that discharges in the form of foam is mounted on the mouth of the container body. A pump former is disclosed in Japanese Patent Application Laid-Open No. 2007-275777 and the like, and is well known. The squeeze foamer squeezes the container body made of a soft synthetic resin with fingers (repeating the compression and decompression operations on the container) to mix the liquid and air in the former with the foam discharge head. It introduce | transduces into a chamber, mixes, and the foam formed with the foam discharger is discharged from a nozzle. The squeeze former is published in Japanese Patent Application Laid-Open No. 2008-291024 and in the June 2009 issue of the magazine “Fragrance Journal” (New Development of Hair Color Technology (-Development of Foam Hair Color Technology)) And the like, which are publicly known.

The foam dispenser of a non-aerosol foamer container has one or more porous membranes for forming foam. Examples of the material for the porous membrane include nylon, polyester, polyethylene, and polypropylene. As the mesh of the porous membrane, for example, 50 to 300 mesh is preferable. The mixing ratio of gas and liquid (gas / liquid mixing ratio) is preferably in the range of gas / liquid = 5/1 to 20/1.

Examples of the present invention will be described below. The technical scope of the present invention is not limited by the following examples.

(Configuration of two-component hair dye)
As shown in Table 1, the solubilized or dispersed hair dye first agent having the composition shown as Examples 1 to 9 in the “first agent” column and the composition shown as Example 1 in the “second agent” column Example 1 to Example 6 and Comparative Example 1 to Example 2 were prepared by preparing a solubilized second hair dye of the conventional method and combining the first agent and the second agent according to each of the above examples selectively. A solubilized or dispersed two-component hair dye according to Comparative Example 3 was constructed. Since the second agent in these examples and comparative examples is common, the column of “first agent” in Table 3 shows the first agent corresponding to each of the solubilized or dispersed examples and comparative examples. Example numbers are displayed.

As shown in Table 2, for the emulsification system, the first agent and the second agent were prepared in a conventional manner with the combinations shown in Formula A and Formula B. The second agent is common in these formulations. In the column of the first agent in Table 3, each prescription corresponding to Example 7 and Comparative Example 4 was displayed.

In Tables 1 and 2, the numerical value indicating the content of the component of the first agent or the second agent is a content notation in units of mass in the first agent or the second agent, the first agent and the second agent It is not the content notation when mixing the agent. Strong ammonia water, monoethanolamine solution, and hydrogen peroxide water are also expressed in percent by mass. Tables 1 and 2 show the components corresponding to any one of the components (A) to (D) of the present invention and the comparative component (A) for the component (A). A message to that effect is displayed outside the box. “POE (5) alkyl (C12-14) ether” in Table 1 is a mixed raw material of POE alkyl ether having 12 to 14 carbon atoms in the alkyl chain.

(Evaluation of formulation stability of the first agent)
The 1st agent of the hair dye adjusted with the solubilization system or the dispersion system, and the emulsification system was left still at room temperature, and the formulation stability of the 1st agent was evaluated. The “evaluation” item in Table 3 was evaluated according to the following evaluation criteria. In the following evaluation, “separation” means that two or more liquid phases are generated in a solubilized system or a dispersed system, and that a uniform emulsion system is impaired and a liquid phase is generated in an emulsion system.

<Evaluation criteria of solubilization system or dispersion system>
◎: After preparation, no separation and cloudiness even after 1 week ○: After preparation, it is separated or clouded in 30 minutes to 1 day ×: After preparation, it is separated or clouded in less than 30 minutes <Evaluation criteria for emulsion system>
◎: After preparation, no separation after 1 week ○: After preparation, it is separated in 1 to 3 days ×: After preparation, it is separated in less than 1 day (Evaluation of lightness imparting effect of two-component hair dye)
<Solubilized or dispersed two-component hair dye>
As a pump former, trade name W-5721 manufactured by Yoshino Kogyo Co., Ltd., WP former pump L nozzle type (gas / liquid mixing ratio: 13/1, discharge amount: 0.9 g (1 push), porous Membrane: Two 90 mesh polyethylene mesh rings) were used.

The first agent and the second agent according to Examples 1 to 6 and Comparative Examples 1 to 3 are contained in the above-described non-aerosol foamer container (pump former) at a mass ratio of 1: 1 and mixed liquid Then, by pressing the pump head part, the mixed liquid was discharged in a foam and applied to 15 cm black human hair. After application, it was allowed to stand at room temperature for 30 minutes, and was treated twice with plain rinse and shampoo by a conventional method to dry the hair. Thereafter, 10 panelists were compared and visually evaluated for the lightness imparted to the hair by the two-component hair dye according to Examples 1 to 4, using Comparative Example 1 as a control. As a result, it was evaluated that any of the two-component hair dyes of Examples 1 to 4 imparted the same lightness as Comparative Example 1 to the hair. In other words, potassium carbonate had the same lightness-imparting effect as sodium carbonate at equivalent amounts. In Examples 5 and 6 in which the amount of potassium carbonate was increased, the lightness imparting effect was higher than in Comparative Example 1.

<Emulsified two-component hair dye>
The 1st agent and 2nd agent which concern on said Example 7 and the comparative example 4 were mixed in the ratio of mass ratio 1: 1, and it apply | coated to 15-cm black human hair. After application, it was allowed to stand at room temperature for 30 minutes, and was treated twice with plain rinse and shampoo by a conventional method to dry the hair. Thereafter, 10 panelists were compared and evaluated visually for the brightness imparted to the hair by the two-component hair dye of Example 7 using Comparative Example 4 as a control. As a result, the two-component hair dye of Example 7 was evaluated to impart the same lightness as Comparative Example 4 to the hair. In other words, potassium carbonate had the same lightness-imparting effect as sodium carbonate at equivalent amounts.

According to the present invention, there is provided a hair cosmetic composition that is excellent in formulation stability even when a carbonate is blended and imparts good lightness to hair.
