The HLB value was calculated by the emulsification method (see "measured value of HLB value by emulsification method" in handbook-cosmetic and pharmaceutical raw materials, "column" nikko chemicals co., Ltd. (published by revised 2/1/1977)) and the like). In the measurement of the actually measured HLB value, sorbitan monostearate (e.g., NIKKOL SS-10 manufactured by Sun chemical Co., Ltd., HLB value 4.7) and polyoxyethylene sorbitan monostearate (e.g., NIKKOLTS-10 manufactured by Sun chemical Co., Ltd., HLB value 14.9) were used in combination as a standard substance of the surfactant. Liquid paraffin was used as the emulsified product. The liquid paraffin is measured at any time in consideration of variations in the type or lot. The liquid paraffin was emulsified with the 2 surfactants described above to determine the most suitable ratio of the surfactants, and the required HLB value (emulsified HLB value) of the liquid paraffin was determined. The calculation formula is shown in formula (1).

[ formula 1 ] for calculation

…(1)

The required HLB value of liquid paraffin is usually about 10.1 to 10.3, although it is affected by the kind or lot. The HLB value of the surfactant to be determined is determined by using liquid paraffin having a desired HLB value. When the unknown surfactant is hydrophilic, it is combined with sorbitan monostearate, and when the unknown surfactant is hydrophobic, it is combined with polyoxyethylene sorbitan monostearate to emulsify the liquid paraffin, and the optimum ratio for stability is obtained, and the HLB value of the unknown surfactant is calculated as x by the formula (1).

These alkaline agents may be contained alone or in combination of two or more. Among them, from the viewpoint of an effect of effectively enhancing the brightness of hair, ammonia, ammonium salts, alkanolamines, and carbonates are preferably used.

The content of the alkaline agent in the hair decoloring/decoloring agent (i.e., the mixture of the first agent and the second agent) when used is preferably adjusted so that the pH value is in the range of 7 to 12, and more preferably adjusted so that the pH value is in the range of 9 to 12, when the hair decoloring/decoloring agent is applied to a general decoloring/decoloring treatment. By adjusting the pH of the mixture to 7 or more, the action of the oxidizing agent contained in the second agent can be promoted. By setting the pH of the mixture to 12 or less, damage to the hair when the hair bleaching/bleaching agent is applied can be suppressed. Further, the pH of the hair decoloring/decoloring agent refers to a pH measured at 25 ℃ of a stock solution of the hair decoloring/decoloring agent.

The first agent may also contain various ingredients that are normally included in hair decolorization/decolorization agents and do not hinder the action of the aforementioned ingredients. For example, the component contained in the second agent may be appropriately contained within a range not to impair the effect of the present invention.

The three-agent hair bleaching/bleaching agent thus constituted can further improve the brightness of hair by using percarbonate as an oxidizing agent.

(three-agent type third agent for hair decoloring/decoloring agent)

The third agent may contain a dispersant in addition to percarbonate. Percarbonate can increase oxidation and thus further improve the brightness of the hair after treatment. As specific examples of the percarbonate, sodium percarbonate, potassium percarbonate, or the like can be given. In these specific examples, only one type may be used, or two or more types may be used in combination.

The form of the third agent is preferably a solid form at 25 ℃ from the viewpoint of formulation stability. The solid form may be, for example, a powder form, a granule form, a tablet form, or the like. The third agent may contain various components which are generally contained in a hair bleaching/bleaching agent and do not inhibit the action of the above-mentioned components.

The method of using the oxidant-containing composition of the present embodiment will be described below.

First, the respective agents of the hair dye or the hair decoloring/decoloring agent composed of a plurality of agents are mixed to prepare a mixture of the hair dye or the hair decoloring/decoloring agent containing an alkaline agent, an oxidizing agent, and the like, and then the mixture is applied to the hair. The mixing method is not particularly limited, and for example, manual stirring using a stirring bar, brush, or the like, or a stirrer, an electric stirrer, or the like may be used. When the mixture is in the form of foam, a method such as shaking foaming may be employed. When applying the hair dye or mixture of hair bleaching/depigmenting agents to the hair, the hair can be applied by known methods, for example by means of a hand covered with a relatively thin glove, by means of a comb or brush to which the mixture is attached. In the case where the mixture is in the form of an aerosol, the mixture may be applied to hair after a plurality of medicines are discharged in a bubble form, or the medicines may be mixed with each other on the hair simultaneously with the application of the medicines to the hair.

After the mixture is applied to the hair, a step of rinsing the mixture applied to the hair with water is performed as in the conventional method after a certain period of time. Then, it is preferable to carry out a step of washing the hair with the hair washing composition and then washing the hair with water as is generally done. The hair cleansing composition is not particularly limited as long as it is a composition applicable to hair cleansing treatment, and known hair cleansing compositions can be used. Then, it is preferable to perform a hair-setting (hair care) treatment of the hair using a hair-setting composition as is generally done, and the hair-setting composition is not particularly limited as long as it is a composition applicable to hair-setting treatment, and a known hair-setting composition can be used. Finally, it is preferable to perform a hair drying process as is commonly done.

By using the oxidizing agent-containing composition of the hair dye or the hair decoloring/decoloring agent of the above embodiment, the following effects can be obtained.

(1) The oxidant-containing composition in the present embodiment contains a component (a), a component (B), and a component (C) in addition to the oxidant. Therefore, the stability of the formulation of the oxidant-containing composition can be improved.

(2) In the present embodiment, when the nonionic surfactant is one selected from a monoglyceride and a polyglycerin fatty acid ester, the formulation stability can be further improved.

(3) In the present embodiment, when the component (C) is a higher alcohol having carbon 20 or more, the stability of the preparation and the miscibility with the first agent can be further improved.

The above embodiment may be modified as described below.

In addition to the oxidation dye, a direct dye described in "standards for materials for pharmaceuticals department of medicine" in standards for materials for pharmaceuticals department of foreign products (release 6.2006, pharmaceutical journal press, japan), for example, may be appropriately contained in the hair dye within a range not affecting the effect of the present invention.

The components (a), (B) and (C) in the oxidant-containing composition of the above embodiment may be directly blended into the oxidant-containing composition and stored, or a part of the other components constituting each drug may be constituted into another drug, and the number of dosage forms may be further increased. Such a constitution can also improve the stability of the preparation.

The hair dye or hair decoloring/decoloring agent according to the above embodiment may be prepared by adding a part of each component contained in each agent constituting the hair dye or hair decoloring/decoloring agent to another agent to increase the number of formulations, within a range in which the effects of the present invention can be achieved.

For example, in the first agent of the above-mentioned hair dye or hair bleaching/depigmenting agent, an alkaline agent may be separately constituted as an additional agent from the components other than the alkaline agent. Furthermore, a multi-agent hair dye or a hair bleaching/removing agent in which a chemical agent containing an oxidation assistant such as persulfate is combined may be formed.

In the above embodiment, the form of the mixture obtained by mixing the respective medicines is not particularly limited, and specific examples thereof include emulsions, gels, foams, creams, and the like of emulsions, aqueous solutions, emulsions, and the like at 25 ℃.
