Description

  The present invention relates to a two-component hair cosmetic that can be easily applied without unevenness on the hair by discharging a mixture of a two-component hair bleaching agent or a two-component hair dye in the form of foam.

  Conventionally, liquid or cream-like hair cosmetics such as hair bleaching agents and hair dyes have been widely used, but it is difficult to apply them uniformly to hair. In particular, skills such as blocking and a matching mirror are required for applying the root portion and the back of the hair, and a lot of time is required.

  Thus, it has been proposed to simplify the hair dyeing operation by discharging the agent in the form of a foam. For example, a two-agent aerosol type or a one-agent non-aerosol type is known. However, the two-component aerosol type is prone to decolorization and dyeing unevenness, metal pressure-resistant containers are oxidized and corroded by hydrogen peroxide, and the internal pressure of the pressure-resistant container rises excessively due to the decomposition of hydrogen peroxide. In addition, the one-agent non-aerosol type has a problem that it is difficult to leave for a long time after application or to repeat the treatment because the effect obtained by one treatment is poor. .

  On the other hand, there has been proposed one in which a two-component hair bleaching agent or a two-component hair dye is discharged in a foam form from a non-aerosol type former container (see Patent Document 1). This is because the liquid mixture of the first agent and the second agent is discharged from the former container in the form of foam, so that it can be applied to the hair without any unevenness and color unevenness does not occur in the finish. It is useful for eliminating the level difference.

  However, in order to cause foaming with a non-aerosol type former container, it is necessary to lower the viscosity of the mixed solution, but on the other hand, it is also required to prevent the mixed solution applied to the hair from dripping down. Is done.

  Patent Document 1 discloses a method of containing a higher alcohol in order to prevent dripping of the mixed solution. However, when a higher alcohol is used, the viscosity of the mixed solution increases when the liquid temperature decreases in winter or the like. Therefore, there is a problem that foaming becomes difficult in the former container.

  The present invention solves this problem and has a foam-like hair bleaching agent that has good foaming properties even at low temperatures and does not sag between the time the mixed solution is applied to the hair and the time it is washed away. Alternatively, an object is to provide a two-component hair dye.

  The present inventors include a specific anionic surfactant, a specific nonionic surfactant, a specific polymer, and a higher polymer in a mixed solution of the first agent and the second agent in a two-component non-aerosol type hair cosmetic. It has been found that the above object can be achieved by containing a specific amount of each alcohol.

That is, the present invention is a two-agent type comprising a first agent containing an alkali agent, a second agent containing hydrogen peroxide, and a former container for discharging a mixture of the first agent and the second agent in the form of foam. A hair cosmetic composition comprising the following components (A) to (D) in the mixed solution:
(A) Alkyl sulfate or polyoxyalkylene alkyl sulfate 0.1 to 5% by weight
(B) Alkyl polyglucoside 0.1-10% by weight
(C) Dimethyldiallylammonium chloride / acrylamide copolymer or dimethyldiallylammonium chloride / acrylamide / acrylic acid copolymer 0.01 to 3% by weight
(D) Higher alcohol 0.01-0.8% by weight
A two-component hair cosmetic composition containing

  According to the present invention, a two-component hair bleaching agent or a two-component hair dye mixture is discharged in the form of foam, and can be applied to the hair easily and without unevenness. Moreover, the foam of the liquid mixture to be discharged becomes a fine state even when the liquid temperature becomes low in winter or the like, is easily adapted to the hair, and does not cause dripping after application to the hair. Furthermore, it does not cause irritation to the scalp or scattering of the agent, and has sufficient decoloring power or dyeing power. Therefore, the hair cosmetic composition of the present invention can easily and comfortably achieve a uniform decolorization finish or hair dye finish with little unevenness.

  Moreover, the liquid mixture discharged in the form of foam by gas-liquid mixing using the former container easily reaches the base of the hair, but there is no accumulation of liquid and the like, and it spreads to the whole hair moderately thinly. Therefore, the root portion does not become extremely bright as in the case of conventional liquid or cream, and decoloring unevenness or staining unevenness due to uneven adhesion of the mixed liquid does not occur. Therefore, by applying the hair cosmetic composition of the present invention to the hair in the vicinity of the newly formed part such as the dividing line and the face line, the color difference between the newly formed part and the already dyed part can be eliminated, and a natural finish can be obtained. . Moreover, since a liquid mixture can be apply | coated to hair moderately thinly, the damage with respect to hair can be reduced.

It is preferable.

  As the product form of the two-component hair cosmetic composition of the present invention comprising the first agent, the second agent and the former container, the first agent or the second agent is filled in a container separate from the former container, and both are used at the time of use.

You may make it enter. In this case, the second agent is a gas permeable container, particularly an oxygen permeable material (for example, polyethylene) in order to prevent the pressure in the container from rising due to oxygen generated by the decomposition of hydrogen peroxide. It is preferable to fill a former container consisting of On the other hand, in order to prevent the oxidation of the oxidation dye, the first agent needs to use a container that does not easily transmit oxygen.
