Description

  The present invention relates to a multi-component hair treatment agent that is a depigmenting agent or an oxidative hair dye, and more specifically includes at least a first agent containing an alkaline agent and a second agent containing an oxidizing agent, The present invention relates to a multi-component hair treatment agent that is mixed and used as a mixture. The present invention also relates to a method for treating hair to be decolorized or dyed, and to a method for treating hair using the multi-component hair treatment agent.

  In order to decolorize or dye hair, a two-component decoloring agent or oxidative hair dye comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent is widely used.

  The mixture in which a conventional decoloring agent or oxidative hair dye is mixed in a container is often creamy or liquid. After being applied to the hair, the cream-like or liquid mixture is left for about 5 to 60 minutes until the hair is decolorized or dyed in the cream-like or liquid state. After the hair is decolorized or dyed, the admixture is washed away.

  A cream-like admixture has a relatively high viscosity, so it is difficult to uniformly attach to hair. For this reason, decoloring unevenness or dyeing unevenness tends to occur in the hair after decoloring or dyeing. In particular, when a practitioner applies a cream-like mixture to his / her own hair, that is, when the cream-like mixture is used on its own, it is not possible to uniformly attach the cream-like mixture to the hair. There is a problem that it is even more difficult and unevenness of decolorization or unevenness of dyeing is particularly likely to occur.

  On the other hand, since the liquid mixture has a relatively low viscosity, it is easy to uniformly adhere to the hair. However, a liquid mixture tends to sag when applied to hair. In particular, when a practitioner uses a liquid mixture for his / her own hair, the liquid mixture often drips when applied to the hair. Further, after the liquid mixture is applied to the hair, the liquid mixture is liable to sag while it is left in a liquid state until the hair is decolored or dyed.

  In recent years, various bleaching agents or oxidative hair dyes have been developed in order to suppress dripping or to enhance decolorization or dyeability. For example, Patent Document 1 below discloses a two-component decoloring agent or an oxidative hair dye, in which at least one of the first agent and the second agent contains a surfactant. The two-component decoloring agent or oxidative hair dye is mixed in a container, and the mixed agent is applied to the hair in a foamed state from the former container.

JP 2004-339216 A

  Conventional decolorizing agents or oxidative hair dyes that are decolorized or dyed in the form of foam have a problem that the mixture tends to sag during application or after standing.

  Moreover, in the decoloring agent or oxidative hair dye described in Patent Document 1, since the mixture is applied to the hair in a foamy state, the mixture is applied to the hair as compared with the case where the liquid mixture is applied to the hair. It is relatively easy to apply, and it is possible to suppress the dripping of the mixture from the hair to some extent at the time of application or after standing after application. However, even the decoloring agent or the oxidative hair dye described in Patent Document 1 may not sufficiently suppress dripping of the mixture during application or during standing after application.

  Furthermore, in the decoloring agent or the oxidative hair dye described in Patent Document 1, since the mixture is applied to the hair in a foamed state, it is difficult to apply the foamed mixture to the hair evenly. In particular, it is difficult to apply a foamy mixture to the root (hairline) part of the hair. For this reason, uneven decolorization or uneven dyeing is likely to occur.

  Furthermore, when the mixture at the time of application is foamy, the amount of decoloring component or dyeing component contained in the same volume of the mixture is reduced as compared with the case of being creamy. For this reason, when the mixture is foamy at the stage of application to the hair, the amount of the mixture attached to the hair tends to be smaller than when the mixture is creamy. For this reason, hair may not be sufficiently decolored or dyed.

  An object of the present invention is a multi-component hair treatment that can make a mixture foam well and can further prevent dripping of the mixture from the hair during application to the hair or during standing after application. And a method for treating hair using the hair treating agent.

The hair treatment agent according to the present invention is a multi-component hair treatment agent that is mixed in a container, discharged from the container in a state where the mixed mixture is in the form of an emulsion or gel, and applied to the hair. Is more preferable. The hair treatment agent according to the present invention is a multi-component hair treatment agent that is applied to the hair in a state where the mixed admixture is in the form of an emulsion or gel, and the mixture applied to the hair is foamed on the hair. It is particularly preferred.

FIGS. 7A and 7B are a perspective view and a front view showing an example of a lid attached to the opening of the container when the hair treatment agent is mixed.

  Hereinafter, the present invention will be described in detail.

  The hair treatment agent according to the present invention is a multi-component bleaching agent or oxidative hair dye. The hair treatment agent according to the present invention includes at least a first agent and a second agent. The first agent does not contain or contain an oxidation dye and contains an alkaline agent. The second agent includes an oxidizing agent. The hair treatment agent according to the present invention is a multi-component hair treatment agent that is mixed and used as a mixture. The first agent is liquid, emulsion or gel. The second agent is liquid, emulsion or gel. The mixture in which the multi-agent hair treatment agent according to the present invention is mixed is an emulsion or a gel. At least one of the first agent and the second agent contains an amphoteric surfactant. At least one of the first agent and the second agent contains a carboxylic acid type anionic surfactant.

  By adopting the above-described configuration in the hair treatment agent according to the present invention, dripping of the mixture from the hair can be suppressed during application to the hair or during standing after application. When the mixture containing the hair treatment agent according to the present invention is applied to the hair in an emulsion or gel state, and the emulsion or gel mixture applied to the hair is foamed on the hair, the hair The dripping of the mixture from the hair during application to the hair can be suppressed, and the dripping of the mixture from the hair during standing after application can be more effectively suppressed.

In addition, by applying the mixture obtained by mixing the hair treatment agent according to the present invention to the hair in an emulsion or gel state, and foaming the emulsion or gel mixture applied to the hair on the hair, After decoloring or dyeing, unevenness in color removal or unevenness in dyeing can be suppressed, and hair can be favorably decolored or dyed.

  In the hair treatment agent according to the present invention, since the first agent is liquid, emulsion or gel before mixing, and the second agent is emulsion, the first agent and the first agent are mixed at the initial stage of mixing. The fluidity of both of the two agents is high, and the mixing properties of the first agent and the second agent are excellent. Even when the first agent and the second agent are uniformly mixed, unevenness in decolorization or unevenness in dyeing can be further suppressed.

  Furthermore, in the hair treatment agent according to the present invention, the mixture obtained by mixing the hair treatment agent becomes an emulsion or a gel. Since the mixed admixture is not a liquid but an emulsion or a gel, the admixture is unlikely to sag when applied to the hair. In addition, when the mixture is in the form of an emulsion or gel rather than a foam at the stage of application to the hair, the emulsion or gel can be easily and even applied to the root (hairline) portion of the hair. It can be applied in a sufficient amount.

  Furthermore, at least one of the first agent and the second agent contains an amphoteric surfactant (A1), and at least one of the first agent and the second agent is a carboxylic acid type anionic. Since the surfactant is included, the mixture can be foamed. Further, after the emulsion or gel mixture is applied to the hair, the emulsion or gel mixture applied to the hair can be foamed on the hair to make a foam. In this way, the mixture can be uniformly attached to the hair by foaming from a milky state or gel state into a foamed state in the manner of shampooing. For this reason, decoloring unevenness or dyeing unevenness hardly occurs in the hair after decoloring or dyeing.

  A cream-like mixture in which a conventional decolorizing agent or oxidative hair dye is mixed has a high viscosity, and thus it may be difficult to uniformly adhere the mixture to the hair. For this reason, there is a problem that when the mixture is left in a cream state and left for about 5 to 60 minutes until the hair is decolored or dyed, it is likely to cause uneven decolorization or uneven dyeing. On the other hand, the mixture can be uniformly attached to the hair by foaming the emulsion or gel-like mixture applied to the hair onto the hair. In particular, even when the practitioner applies the emulsion or gel mixture to his / her hair, that is, when the emulsion or gel mixture is used by himself, the emulsion applied to the hair or By foaming the gel-like admixture on the hair and making it into a foam, the admixture can be uniformly attached to the hair. Therefore, the use of the hair treatment agent according to the present invention can remarkably suppress the hair from being decolored or dyed.

  Furthermore, the conventional decoloring agent or oxidative hair dye has a problem that the mixture tends to sag during application and during standing after application. On the other hand, the use of the hair treatment agent according to the present invention significantly suppresses dripping of the mixture during standing after application and after application.

  Hereinafter, details of the first agent and the second agent, details of the multi-component hair treatment agent, and details of the hair treatment method using the multi-component hair treatment agent will be described.

Nonionic surfactant (B) (second surfactant component):
At least one of the first agent and the second agent preferably contains a nonionic surfactant (B). The first agent preferably contains a nonionic surfactant (B). The second agent preferably contains a nonionic surfactant (B). When the admixture contains the nonionic surfactant (B), dripping of the admixture during application to the hair is further suppressed, and dripping of the applied admixture from the hair is further suppressed. Furthermore, foaming of the emulsion or gel-like admixture is improved by including a nonionic surfactant having a branched alkyl group bonded to an oxygen atom, which will be described later, as the second surfactant component. Furthermore, after the emulsion or gel mixture is applied to the hair, the gel or emulsion mixture applied to the hair can be foamed on the hair to make a foam. In this way, the mixture can be uniformly attached to the hair by foaming from a gel or milky state into a foamed state in the manner of shampooing. For this reason, decoloring unevenness or dyeing unevenness hardly occurs in the hair after decoloring or dyeing. As for nonionic surfactant (B), only 1 type may be used and 2 or more types may be used together.

  In addition, the hair may be conditioned using a hair styling agent such as a hair wax containing an oil such as waxes or hydrocarbons. A large amount of oil is attached to the hair that has been styled with such hair wax. In addition, oil agents often remain in hair even after the hair that has been trimmed with hair wax is washed.

  Therefore, when an oil such as hair wax is attached to the hair, it may be defoamed when a conventional foaming agent that is a decoloring agent or oxidative hair dye is applied to the hair. Moreover, the viscosity of the defoamed material produced by the defoaming of the foam is lowered, and the defoamed material may sag during application or during standing after application. Furthermore, in the conventional decoloring agent or oxidative hair dye, even if an attempt is made to further foam the foamy mixture applied to the hair, it may not be sufficiently foamed.

  On the other hand, when the mixed agent contains a nonionic surfactant having a branched alkyl group bonded to an oxygen atom as the second surfactant component, the oil agent derived from the hair styling agent such as hair wax adheres to the hair. Even if it does, the mixture foams well on the hair, and the defoaming is effectively suppressed.

  Examples of the nonionic surfactant (B) include sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, polyoxyalkylene alkyl ether, polyoxyalkylene fatty acid ester, polyoxyalkylene sorbitan fatty acid ester, polyoxyalkylene castor oil, Examples include polyoxyalkylene hydrogenated castor oil, sucrose fatty acid ester, alkyl polyglucoside, and polyoxyethylene lanolin. These alkylene oxide adducts may be used. Nonionic surfactants (B) other than these may be used.

  From the viewpoint of suppressing dripping and the foaming of the mixture, as the nonionic surfactant (B), polyoxyalkylene alkyl ether, glycerin fatty acid ester, polyoxyalkylene fatty acid ester, polyoxyalkylene castor oil, polyoxyalkylene It is preferable to use hydrogenated castor oil and alkyl polyglucoside, and it is more preferable to use polyoxyalkylene alkyl ether. Specific examples of the polyoxyalkylene alkyl ether include polyoxyethylene cetyl ether, polyoxyethylene stearyl ether, polyoxyethylene behenyl ether and polyoxyethylene octyldodecyl ether. In addition, the addition mole number of the alkylene oxide of the said polyoxyalkylene alkyl ether is not specifically limited.

From the viewpoint of suppressing dripping and the viewpoint of foaming of the mixed agent, it is preferable that the first agent contains a nonionic surfactant (B).

  It is preferable that at least one of the first agent and the second agent contains a nonionic surfactant having a branched alkyl group bonded to an oxygen atom. The first agent preferably contains a nonionic surfactant having a branched alkyl group bonded to an oxygen atom. The second agent preferably contains a nonionic surfactant having a branched alkyl group bonded to an oxygen atom. By using a nonionic surfactant having a branched alkyl group bonded to an oxygen atom, the foaming of the mixture becomes even better.

  Examples of the branched alkyl group bonded to the oxygen atom include isopropyl, isobutyl, sec-butyl, 2-ethylhexyl, 2-methyldodecyl, 2-methyltetradecyl, 2-butyloctyl, and 2-hexyl. Examples include decyl group, 2-heptylundecyl group, 2-octyldodecyl group, 2-decyltetradecyl group, and 5,7,7-trimethyl-2- (1,3,3-trimethylbutyl) octyl group.

  From the viewpoint of effectively suppressing the dripping of the mixture from the hair during application to the hair or during standing after application, and having the branched alkyl group bonded to the oxygen atom from the viewpoint of effectively foaming the mixture The nonionic surfactant preferably has a polyoxyalkylene structural unit.

The polyoxyalkylene structural unit is a structural unit represented by-(RO) _n- . R is preferably an alkylene group having 1 to 5 carbon atoms, and n is preferably an integer of 1 to 50.

  Each content of the nonionic surfactant (B) in the first agent and the second agent is appropriately adjusted in consideration of dripping from the hair or foaming when the mixture is foamed.
