(First embodiment)
Hereinafter, a first embodiment in which the hair cosmetic composition according to the present invention is embodied as a hair decoloring / decoloring agent will be described. The hair cosmetic composition is used for decoloring and decoloring hair as a two-component hair decoloring and decoloring agent. The hair cosmetic composition is also used as a three-component decoloring / destaining agent.

<Two-component hair decoloring and decoloring agent>
The hair cosmetic composition in the two-component hair bleaching / destaining agent is composed of a solid first agent containing, for example, an alkaline agent and a liquid second agent containing, for example, a solvent. After the first agent and the second agent are mixed, a foamy dosage form is formed by a foaming operation in which foaming is performed by shaking, and then applied to the hair as a hair bleaching and decoloring agent.

<First Agent>
In addition to the alkaline agent, the first agent contains at least one selected from an oxidizing agent, (A) an ester-type nonionic surfactant, and (B) an amphoteric surfactant and an anionic surfactant.

Specific examples of the ester type nonionic surfactant include, for example, polyoxyethylene monooleate (hereinafter referred to as “POE”) sorbitan, POE sorbitan monostearate, POE sorbitan monopalmitate, POE sorbitan monolaurate, triolein Acid POE sorbitan, monostearic acid POE glycerin, monomyristic acid POE glycerin, tetraoleic acid POE sorbit, hexastearic acid POE sorbit, monolauric acid POE sorbit, POE sorbite beeswax, monooleic acid polyethylene glycol, monostearic acid polyethylene glycol, monolaurin Polyethylene glycol acid, lipophilic glyceryl monooleate, lipophilic glyceryl monostearate, self-emulsifying glyceryl monostearate Sorbitan monooleate, sorbitan sesquioleate, sorbitan trioleate, sorbitan monostearate, sorbitan monopalmitate, sorbitan monolaurate, sucrose fatty acid ester, decaglyceryl monolaurate, decaglyceryl monostearate, monooleic acid Examples include decaglyceryl and decaglyceryl monomyristate. Of the specific examples of these nonionic surfactants, only one kind may be contained alone, or two or more kinds may be contained in combination. Among these, sucrose fatty acid esters are preferably applied from the viewpoint of improving touch. Since sucrose fatty acid ester is solid (powder) at normal temperature (25 ° C.), it can be easily stored as a powder when the first agent is solid. Further, the mixing and solubility of the second agent with a solvent such as water is also better than other ester-type nonionic surfactants.

  Moreover, it is preferable that 2 or more types of ester type nonionic surfactants from which HLB differs are used for (A) ester type nonionic surfactant from a viewpoint of a touch improvement.

It is a numerical value that is conceived by Griffin and is given to nonionic surfactants, and balances the strength of lipophilic groups (alkyl groups) and hydrophilic groups (ethylene oxide chains) of nonionic surfactants. It is expressed in numbers. The required HLB indicates the HLB value of the surfactant that provides the best emulsified state for the oil to be emulsified. The actual value calculated from the emulsification method is used as the HLB value (see “Handbook-Cosmetics / Formulation raw materials-” Nikko Chemicals Co., Ltd. (issued on February 1, 1977)). For the measurement of the measured HLB value, sorbitan monostearate (for example, NIKKOL SS-10 manufactured by Nikko Chemicals Co., Ltd., HLB value 4.7) and polyoxyethylene sorbitan monostearate (for example, Nikko Chemicals Co., Ltd.) were used as standard substances for the surfactant. NIKKOL TS-10 manufactured by HLB value 14.9) is used in combination. Liquid paraffin is used for the emulsion. In addition, liquid paraffin is measured every time when variation by type or lot is considered. Liquid paraffin is emulsified with the above two types of surfactants, the optimal surfactant ratio is determined, and the required HLB value of the liquid paraffin (the emulsified HLB value) is determined. The calculation formula is shown in Formula (1).

通常流動パラフィンの所要ＨＬＢ値は、種類及びロットにもよるが１０．１〜１０．３程度である。次に未知の界面活性剤のＨＬＢの測定は、所要ＨＬＢ値を求めた流動パラフィンを用いて測定する。未知の界面活性剤が親水性であればモノステアリン酸ソルビタンと組み合わせ、未知の界面活性剤が疎水性であればモノステアリン酸ポリオキシエチレンソルビタンと組み合わせて、上記流動パラフィンを乳化し、安定性のあるところの最適割合を求め、未知の界面活性剤のＨＬＢ値をｘとして上記数式（１）にあてはめて算出する。

Usually, the required HLB value of liquid paraffin is about 10.1 to 10.3 depending on the type and lot. Next, the HLB of an unknown surfactant is measured using liquid paraffin from which the required HLB value has been determined. If the unknown surfactant is hydrophilic, it is combined with sorbitan monostearate, and if the unknown surfactant is hydrophobic, it is combined with polyoxyethylene sorbitan monostearate to emulsify the liquid paraffin, A certain optimum ratio is obtained, and the HLB value of the unknown surfactant is set as x and calculated by applying the above formula (1).

  The hair dye which concerns on this embodiment is comprised from the solid 1st agent containing an alkali agent, an oxidation dye, etc., for example, and the liquid 2nd agent containing a solvent etc., for example. After the first agent and the second agent are mixed, a foamy dosage form is formed by a foaming operation in which foaming is performed by shaking and then applied to the hair as a hair dye.

  In addition to the alkaline agent, the first agent contains at least one selected from an oxidizing agent, (A) an ester-type nonionic surfactant, and (B) an amphoteric surfactant and an anionic surfactant. Oxidative dyes are compounds that can develop color due to oxidative polymerization with an oxidizing agent, and are classified as dye intermediates and couplers. The oxidation dye contains at least a dye intermediate.

  Examples of the dye intermediate include p-phenylenediamine, toluene-2,5-diamine (paratolylenediamine), N-phenyl-p-phenylenediamine, 4,4′-diaminodiphenylamine, p-aminophenol, o- Aminophenol, p-methylaminophenol, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, 2-hydroxyethyl-p-phenylenediamine, o-chloro-p-phenylenediamine, 4-amino-m -Cresol, 2-amino-4-hydroxyethylaminoanisole, 2,4-diaminophenol, and salts thereof. Among these specific examples, only 1 type may be contained independently and 2 or more types may be combined and contained.

  Couplers develop color by binding to dye intermediates. Examples of the coupler include resorcin, 5-amino-o-cresol, m-aminophenol, α-naphthol, 5- (2-hydroxyethylamino) -2-methylphenol, m-phenylenediamine, and 2,4-diaminophenoxyethanol. , Toluene-3,4-diamine, 2,6-diaminopyridine, diphenylamine, N, N-diethyl-m-aminophenol, phenylmethylpyrazolone, and salts thereof. Among these specific examples, only 1 type may be contained independently and 2 or more types may be combined and contained. Since the oxidative dye can change the color tone of the hair in various ways, it is preferable that at least one selected from the specific examples of the dye intermediate and at least one selected from the specific examples of the coupler. Composed. The first agent is suitably selected from dyes other than the above-mentioned oxidation dyes, for example, at least one selected from oxidation dyes and direct dyes listed in "Quasi-drug raw material standards" (issued in June 2006, Yakuji Nippo). You may contain. Moreover, as components other than the component mentioned above contained in a 1st agent, components other than the alkali agent and oxidizing agent which are contained in the 1st agent which concerns on 1st Embodiment are mentioned.

The second agent in the hair dye is used for dyeing hair after being mixed with the first agent. The specific configuration of the second agent is the same as that of the second agent according to the first embodiment.
In the present embodiment, the dosage form of the first agent is configured in a solid state. The dosage form of the second agent is configured in a liquid state. After the first agent and the second agent are mixed, the hair dye is foamed by shaking, and then a foamy dosage form is formed. Then, the required amount of the mixture becomes a thin glove. It is applied to the hair by attaching it to the hands, combs or brushes.

The hair dye according to the present embodiment has the following advantages in addition to the effects of the first embodiment.
(6) The hair dye according to this embodiment is a hair cosmetic composition in the form of a foamy preparation, wherein (A) an ester-type nonionic surfactant and (B) an amphoteric surfactant and an anion At least one selected from the surfactants is blended, and the total content of all the surfactants is 2 to 10% by mass. Therefore, foamability and hair feel can be improved.

The embodiment may be modified as follows.
-In the hair cosmetic composition of the said embodiment, the 1st agent was comprised in solid form. However, the first agent may be configured as a liquid agent by adding a solvent. In that case, the oxidizing agent is preferably configured as a separate agent from the first agent containing the alkaline agent. When the first agent is a liquid agent, for example, ammonia and alkanolamine can be further used as an alkaline agent that is liquid at 25 ° C. Examples of the alkanolamine include monoethanolamine and triethanolamine.

  -In the hair cosmetic composition of the said embodiment, the 1st agent was comprised in the powder form and the 2nd agent was comprised in the liquid state. However, by configuring a part of the components contained in the first agent or the second agent as a separate agent, it may be configured as a multi-agent type, for example, three or more types.

  -In the hair cosmetic composition of the said embodiment, the solid oxidizing agent was mix | blended in the 1st agent. However, you may comprise by mix | blending an oxidizing agent in a 1st agent, and using a liquid or solid oxidizing agent in a 2nd agent.

  -In the hair cosmetic composition of the said embodiment, the 1st agent was comprised in the powder form and the 2nd agent was comprised in the liquid state. Therefore, it is preferable to mix a solid surfactant in the first agent and a liquid surfactant in the second agent.

  The foaming operation can be changed as follows. That is, a foaming operation in which air is mixed into the hair cosmetic composition by applying vibration to the hair cosmetic composition, or air is mixed into the hair cosmetic composition by adding rotation to the hair cosmetic composition. It can also be changed to a foaming operation. That is, the foaming operation of foaming by shaking the hair cosmetic composition is an operation of shaking and mixing the hair cosmetic composition, an operation of applying vibration to the hair cosmetic composition, and an operation of rotating the hair cosmetic composition. It means that it is made to foam by at least one kind of operation.

  Depending on the type of foaming operation, the foaming tool for foaming the hair cosmetic composition can be changed. For example, in the case of a foaming operation in which vibration is mainly applied, as the foaming tool, for example, a vibration exciter and a manual type whisk are suitable. Further, for example, in the case of a foaming operation in which rotation is mainly applied, for example, a stirrer, a stirrer, and an electric whisk are suitable as the foaming tool. Such foaming operation is performed in the container by putting the hair cosmetic composition into, for example, a container having an opening at the upper end. Even when such a foaming tool is used, according to the hair cosmetic composition of the embodiment, it is easy to enhance foamability.

Next, the embodiment will be described more specifically with reference to examples and comparative examples.
The 1st agent and 2nd agent of the hair dye containing each component shown in Tables 1-3 were prepared. The numerical value in the column which shows each component in Tables 1-3 shows content of the component of the said column, The unit is the mass%. In the present example and the comparative example, the first agent is prepared in a powder form and the second agent is prepared in a liquid state. And a hair dye is prepared by mixing the 1st agent and the 2nd agent with the mass ratio shown in a table | surface using the container which can be closed shown in FIG. The capacity of the closable container is 770 mL, the height is 17 cm, and the inner diameter is 7 cm to 8 cm. Each agent was put into the closable container so that the mixture of the first agent and the second agent was 150 g, and the closable container was shaken up and down 20 times. A foamy dosage form was obtained by performing a foaming operation in which air was shaken and mixed with such a hair bleaching agent.

  The obtained foamy hair dye was taken in hands (wearing gloves), applied to a black human hair bundle (hereinafter simply referred to as a hair bundle), and allowed to stand at room temperature (25 ° C.) for 30 minutes. Then, the hair dye attached to the hair bundle was washed away with water, and the hair bundle was shampooed twice and rinsed once. Subsequently, the hair bundle was dried with warm air and then left for one day to obtain a hair bundle that had been dyed. The feel of the hair bundle subjected to the hair dyeing treatment was evaluated according to the following method. Moreover, it evaluated according to the method shown below about the foamability at the time of foaming the hair dye of the Example shown in Tables 1-3, and a comparative example.
