JP5824763B2 - Decoloring agent or oxidative hair dye, and method for decoloring or dyeing hair - Google Patents

Description

  The present invention relates to a multi-component decoloring agent or oxidative hair dye that includes at least a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and is mixed and used as a mixing agent. The present invention also relates to a method for decoloring or dyeing hair using the multi-component decoloring agent or oxidative hair dye.

  In order to decolorize or dye hair, a two-component decoloring agent or oxidative hair dye containing 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 the liquid mixture is used on its own, 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

  In the depigmenting agent or oxidation dyeing agent described in Patent Document 1, since the mixture is applied to the hair in a foamy state, the mixture is applied relatively to the hair as compared with the case where the liquid mixture is applied to the hair. It is easy to do, and it is possible to suppress dripping of the mixture from the hair to some extent at the time of application or after standing after application.

  However, since the mixture is applied to the hair in a foamed state, it is difficult to uniformly apply the foamed mixture to the hair. 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 is in the form of foam, the amount of the decoloring component or dyeing component contained in the same volume of the mixture is reduced as compared with the case where the mixture is in the form of cream. 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.

  By the way, hair may be hair-styled using a hair-styling agent. As the hair styling agent, for example, a hair wax containing an oil such as waxes or hydrocarbons is used. 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.

  In the depigmenting agent or the oxidative hair dye described in Patent Document 1, if the mixture is applied in a foamy state to hair to which a hairdressing agent containing an oil agent is attached, the defoaming may occur. 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 decoloring agent or the oxidative hair dye described in Patent Document 1, even if an attempt is made to further foam the foamy mixture applied to the hair, it may not be sufficiently foamed.

  The object of the present invention is to reduce the dripping of the admixture from the hair when it is applied and when it is left after application, and to allow the admixture to foam well on the hair. It is to provide a hair coloring agent and a method for decoloring or dyeing hair using the multi-component bleaching agent or oxidation hair coloring agent.

  Hereinafter, the present invention will be described in detail.

  The decoloring agent or oxidative hair dye according to the present invention includes at least a first agent containing an alkaline agent and a second agent containing an oxidizing agent. The decoloring agent or oxidative hair dye according to the present invention is a multi-component decoloring agent or oxidative hair dye that is mixed and used as a mixed agent. The first agent is liquid or gel. The second agent is also liquid or gel. When the multi-component bleaching agent or oxidative hair dye is an oxidative hair dye, the first agent further includes an oxidative dye in addition to the alkaline agent. At least one of the first agent and the second agent contains at least one first surfactant component (A) of an anionic surfactant and an amphoteric surfactant. At least one of the first agent and the second agent contains a nonionic surfactant as the second surfactant component (B). The mixed agent in which the decoloring agent or the oxidative hair dye according to the present invention is mixed is in a gel form.

  By adopting the above configuration in the present invention, it is possible to suppress dripping of the mixture during application to the hair, and it is also possible to inhibit dripping of the applied mixture from the hair. Further, by adopting the above-described configuration in the present invention, since at least one of the first agent and the second agent contains a nonionic surfactant as the second surfactant component (B), it is a mixture on the hair. Can be foamed well. In particular, even if an oil agent derived from a hair styling agent or the like adheres to the hair, the mixture can be foamed well on the hair.

  When the hair wax is attached to the hair, when the foam-like mixture that is a conventional decoloring agent or oxidative hair dye is applied to the hair, it defoams or the defoamed material produced by the defoaming May sag. Furthermore, after applying a foamy mixture that is a conventional decoloring agent or oxidative hair dye to the hair, even if an attempt is made to further foam the foamed mixture applied to the hair, the foam may not be sufficiently foamed. On the other hand, the use of the decoloring agent or the oxidative hair dye according to the present invention can foam the mixture well on the hair even if the oil derived from hair wax or the like is attached to the hair. Defoaming can be effectively suppressed.

  Furthermore, hair can be favorably decolored or dyed by adopting the above-described configuration in the present invention. By using the decoloring agent or the oxidative hair dye according to the present invention, it is possible to suppress uneven decoloring or uneven dyeing after decoloring or dyeing.

  In the decoloring agent or oxidative hair dye according to the present invention, both the first agent and the second agent are liquid or gel-like at the stage before mixing, so both the first agent and the second agent at the initial stage of mixing. The fluidity of the first agent and the second agent is excellent. By uniformly mixing the first agent and the second agent, it is possible to further suppress uneven decolorization or uneven dyeing.

  Furthermore, since the mixture which mixed the decoloring agent or oxidative hair dye which concerns on this invention is not a liquid but a gel form, it is hard to spill a mixture at the time of application to hair. In addition, since the mixture is in the form of a gel rather than a foam at the stage of application to the hair, the gel-like mixture can be easily and sufficiently applied even at the root (hairline) part of the hair. it can.

  Furthermore, at least one of the first agent and the second agent includes at least one first surfactant component (A) of an anionic surfactant and an amphoteric surfactant and a nonionic surfactant. The second surfactant component (B), which is an agent, so that after the gel-like mixture is applied to the hair, the gel-like mixture applied to the hair is foamed into a foam it can. Thus, the mixture can be uniformly attached to the hair by bubbling from the gel state in the manner of shampooing into a foam state. For this reason, it is possible to make it difficult to cause uneven decolorization or uneven dyeing 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 made to adhere uniformly to the hair by foaming the gel-like mixture applied to the hair. In particular, even when the practitioner applies the gel-like mixture to his / her own hair, that is, when the gel-like mixture is used by himself, the foamed gel-like mixture applied to the hair is foamed. By making it into a shape, the mixture can be adhered to the hair evenly. Therefore, the use of the decoloring agent or the oxidative hair dye according to the present invention can remarkably suppress the hair decoloring unevenness or dyeing unevenness.

  At least one of the first agent and the second agent preferably contains a thickening polymer (C). When at least one of the first agent and the second agent contains the thickening polymer (C), the mixture obtained by mixing the decolorizing agent or the oxidative hair dye according to the present invention is even better. Become a gel. For this reason, the mixture becomes more difficult to sag during application to the hair.
