Description

Oxidizing agent-containing composition and method for stabilizing oxidizing agent

Technical Field

The present invention relates to an oxidizing agent, and more particularly to an oxidizing agent-containing composition for improving the stability of hydrogen peroxide and a method for stabilizing an oxidizing agent.

Background

Generally, hair treatment compositions such as hair dyes, hair bleaching/bleaching agents, and hair perming agents that exhibit an effect by mixing a plurality of agents are known. As such a hair treatment composition, for example, an oxidation hair dye comprising a first agent containing an alkali agent and an oxidation dye and a second agent (composition containing an oxidizing agent) containing an oxidizing agent such as hydrogen peroxide is known.

Among them, for example, hydrogen peroxide, which is an unstable compound, is easily decomposed into water and oxygen, and thus it is difficult to maintain the stability of the hydrogen peroxide-containing composition for a long period of time. Conventionally, there are oxidant-containing compositions using a specific stabilizer for the purpose of improving the stability of an oxidizing agent. For example, patent document 1 discloses a composition for reducing decomposition of hydrogen peroxide by containing 1-hydroxyethane-1, 1-diphosphonic acid or the like. Further, patent document 2 discloses a hydrogen peroxide-containing composition containing pyrrolidonecarboxylate or the like.

In addition, when it is a solid dosage form, it can be mixed with dispersing agent, such as calcium stearate or magnesium stearate metal salt, sodium sulfate, talc, lactose and low substituted degree hydroxypropyl cellulose. In these specific examples, only one type may be used, or two or more types may be used in combination.

< three-agent type Hair Decoloration/Decoloration agent >

Three-agent hair depigmenting/depigmenting agents, for example, may include: a first agent having the same composition as the first agent of the two-agent hair-bleaching/depigmenting agent, a second agent having the same composition as the second agent of the two-agent hair-bleaching/depigmenting agent, and a third agent containing at least percarbonate. 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. For example, the components contained in the first and second agents may be appropriately contained within a range not to impair the effects of the present invention.

< two-pack type hair dye >

The two-pack type hair dye may include, for example: a first agent containing at least an alkaline agent and an oxidation dye, and a second agent containing at least an oxidizing agent. Hereinafter, the difference from the above-described hair bleaching/bleaching agent will be mainly described.

(second agent for two-agent type hair dye)

The second agent for hair dye may have, for example, the same composition as the second agent for hair decoloring/decoloring agent described above.

(first agent of two-agent type hair dye)

The first part of the hair dye contains, for example, an alkaline agent and an oxidation dye. As an example of the alkaline agent contained in the first agent, the same ingredients as those described in the specific examples of the alkaline agent used in the above-described hair bleaching/bleaching agent can be used. The oxidation dye is a colorable compound formed by oxidation polymerization of an oxidizing agent and can be divided into a dye intermediate and a coupling agent, and the oxidation dye preferably contains the dye intermediate and the coupling agent at the same time.

As the dye intermediate, for example, there may be mentioned: p-phenylenediamine, toluene-2, 5-diamine (p-toluenediamine), N-phenyl-p-phenylenediamine, 4' -diaminodiphenylamine, p-aminophenol, o-aminophenol, p-methylaminophenol, 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, 1-hydroxyethyl-4, 5-diaminopyrazole, and salts thereof. Specific examples of the salt include hydrochloride, sulfate, and the like. These dye intermediates may be used alone or in combination of two or more.

The coupler may be, for example, resorcinol, 5-amino-o-cresol, m-aminophenol, α -naphthol, 5- (2-hydroxyethylamino) -2-methylphenol, m-phenylenediamine, 2, 4-diaminophenoxy, toluene-3, 4-diamine, 2, 6-diaminopyridine, diphenylamine, N-diethyl-m-aminophenol, phenylmethylpyrazolone, 1, 5-dihydroxynaphthalene, and salts thereof, and specific examples of the salts may be, for example, hydrochloride, sulfate, and the like.

The lower limit of the content of the oxidation dye in the hair dye can be appropriately set, and is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, and still more preferably 0.5% by mass or more. When the content of the oxidation dye is 0.01% by mass or more, the color tone can be further improved.

The upper limit of the content of the oxidation dye in the hair dye may be set as appropriate, and is preferably 10% by mass or less, more preferably 7% by mass or less, and still more preferably 5% by mass or less. When the content of the oxidation dye is 10% by mass or less, the solubility to a solvable agent can be improved in the case of using the solvable agent.

The first agent may contain, if necessary, components other than the above-described components, and for example, may further contain components contained in the first agent and the second agent of the above-described hair decoloring/decoloring agent.

< three-pack type hair dye >

The three-part hair dye, for example, may include: a first part having the same composition as the first part in the above-mentioned two-part hair dye, a second part having the same composition as the second part in the above-mentioned two-part hair dye, and a third part containing at least percarbonate. The three-component hair dye having such a structure can further improve the brightness of hair by using percarbonate as an oxidizing agent.

(third agent of three-agent type hair dye)

The third agent of the hair dye has, for example, the same composition as the third agent of the above-described hair decoloring/decoloring agent. Percarbonate can increase oxidation and improve the brightness of hair after hair treatment. Therefore, the concealment of white hair can be improved.

Hereinafter, a method of using the oxidant-containing composition of the present embodiment as a hair dye or a hair decoloring/decoloring agent composed of a plurality of agents will be described.

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 oxidant-containing composition of the above embodiment, the following effects can be obtained.

(1) The oxidant-containing composition of the present embodiment can improve the stability of the oxidant (particularly, hydrogen peroxide) by the components (a) to (C) contained therein in addition to the oxidant. Further, the effect of dyeing or decoloring/decoloring can be sufficiently exhibited without lowering the effect.

(2) The oxidant-containing composition of the present embodiment contains the component (D) to the component (F). Therefore, the stability of the formulation of the oxidant-containing composition can be improved. In particular, even when the stannate (a) is incorporated in a large amount, the decrease in the stability of the preparation due to the stannate (a) can be suppressed.

The above embodiment may be modified as follows.

For example, the hair dye may contain, in addition to the oxidation dye, a direct dye as described in "standards for materials for pharmaceuticals department of medicine" in the standards for materials for pharmaceuticals department of external products (release 6.2006, japan), as long as the effects of the present invention are not impaired.

The respective components (a) to (F) 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 oxidizing agent and 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 ℃.

The oxidant-containing composition according to the above embodiment can be used as a second agent for a multi-agent hair dye or a hair bleaching/removing agent. The oxidizing agent-containing composition may be used as a second agent for a permanent wave agent containing an oxidizing agent, in addition to the above embodiments. In this configuration, the stability of the oxidizing agent (particularly, hydrogen peroxide) in the second agent can be improved as well. Moreover, the effect of permanent wave can be fully exerted without reducing the effect of permanent wave.

The oxidant-containing composition according to the above embodiment can be used as a second agent for a multi-agent hair dye or a hair bleaching/removing agent. In the case of applying the above embodiment, it is also possible to use, as a method for stabilizing an oxidizing agent, a method in which in a composition containing an oxidizing agent, a) stannate, (B) an aminocarboxylic acid type chelating agent, and (C) an acid are prepared so that the mass ratio of the content of the component (B) to the content of the component (a) is 0.01 to 35, and the pH of the composition containing an oxidizing agent is adjusted to 2 to 5.

Examples

The embodiments will be described in more detail below with reference to the following examples and comparative examples. The present invention is not limited to the configurations described in the following examples.

A first agent for an oxidative hair dye and a second agent as an oxidant-containing composition, each containing the components shown in tables 1 to 4, were prepared separately. In each table, the numerical value in each column indicating each component represents the content of the component in the column, and the unit thereof is mass%. In the tables, "(A)" to "(F)" indicate compounds corresponding to the respective components (A) to (F) described in the claims of the present application. The values in parentheses for POE in the compound name indicate the additional moles of e.o. The first agent and the second agent of the oxidation hair dye shown in tables 1 to 4 were mixed in a mass ratio of 1:1 to prepare a milky oxidation hair dye.

The obtained oxidation hair dye was applied to a black or white hair strand (10 cm of a hair strand manufactured by BEALAX K.K.) by brushing, and left at 30 ℃ for 30 minutes. Then, after the oxidation hair dye applied to the hair strand was washed with water, the hair strand was subjected to shampooing 2 times (Vigene treatment shampoo manufactured by friend Co., Ltd.) and then to touch-off 1 time (Vigene treatment lotion manufactured by friend Co., Ltd.) as a touch-off composition. In addition, the hair cleansing composition and the hair rinse composition were rinsed with water after each treatment. Thereafter, the tress was dried by warm air and left for one day. The stability of the oxidizing agent in the second agent before mixing with the first agent and the formulation stability of the second agent were evaluated by the following methods.

(stability of oxidizing agent)

The hydrogen peroxide as the oxidizing agent in the second agent was placed in a polyethylene container, and then left at 60 ℃ for 7 days, and the amount of the remaining hydrogen peroxide was quantified by redox titration to calculate the remaining amount of hydrogen peroxide. The evaluation criteria were divided into the following 4 stages, and as a result of the evaluation, the residual rate of hydrogen peroxide was 99 mass% or more, as "good: 4 ", rated as" fair with 98% by mass or more and less than 99% by mass: 3 "is evaluated as" slightly poor "when 96% by mass or more and less than 98% by mass: 2 "and rated as" poor "at less than 96 mass%: 1".

(formulation stability of second agent)

Regarding the formulation stability of the second agent formed into a liquid state, it was put into a container made of polyethylene, and after being left at 50 ℃ for 1 day, judgment was made by evaluating the separation state of the second agent by visual observation by 5 judges. As the evaluation results, the score was excellent (5 points) in the case of no separation at all, good (4 points) in the case of no separation at all, fair (3 points) in the case of slight separation, poor (2 points) in the case of more separation, and poor (1 point) in the case of many separations, and the average value was calculated from the results of the scores of the respective judges. The evaluation was "excellent (5 points)" when the average value was 4.6 or more, "good (4 points)" when the average value was 3.6 or more and less than 4.6, "fair (3 points)" when the average value was 2.6 or more and less than 3.6, and "slightly poor (2 points)" when the average value was 1.6 or more and less than 2.6, and "poor (1 point)" when the average value was less than 1.6.

As shown in tables 1 and 2, it was confirmed that the results of the examples were acceptable according to the above evaluation items. As is clear from table 3, comparative example 1 containing no component (a) was inferior to the examples in evaluation of the stability of the oxidizing agent. On the other hand, comparative example 2 containing no component (B) was inferior to the examples in the evaluation of the stability of the oxidizing agent. On the other hand, in comparative example 3 in which the mass ratio of the content of the component (B) to the content of the component (a) exceeds 35, the evaluation of the stability of the oxidizing agent was inferior to that of each example. Comparative example 4, in which the pH of the second agent was 6, was inferior to the examples in the evaluation of the stability of the oxidizing agent.
