  The main agent and the auxiliary agent configured as described above are stored as a individually packaged package until use. In addition, it does not specifically limit as a packaging form of each agent, For example, any of bottle packaging, pillow packaging, and tube packaging may be sufficient. It is preferable that such a main agent and an auxiliary agent are provided as a hair coloring product including a foaming tool for performing foaming by shaking.

Next, the foaming tool will be described.
The foaming tool of this embodiment is a closable container that enables oxidative hair dyes to be liquid-tightly closed. As shown in FIG. 1A, the closable container 20 includes a bottomed cylindrical container body 21 and a lid body 22 that closes the opening of the container body 21.

  A flange-like fitting portion is formed on the peripheral edge portion of the lid body 22, and this fitting portion is fitted into the opening of the container main body 21. In addition, in the closable container 20 of this embodiment, the lid 22 is liquid-tightly mounted by fitting the fitting portion into the opening of the container body 21 and rotating the lid 22. However, the structure for closing the container body 21 is not particularly limited. For example, the groove may be closed by a structure in which a groove is formed in the lid and the groove is press-fitted into a protrusion formed on the periphery of the opening of the container body.

  The occluding container 20 is formed so that the main package 11 and the secondary package 12 can be accommodated. In the closable container 20, each agent can be stored together as an exterior container of the oxidative hair dye 10. The occluding container 20 of the present embodiment is formed so as to accommodate accessories such as gloves and instructions used during the hair dyeing process. Such a closable container is preferably formed from a resin material or a paper material imparted with water resistance from the viewpoint of weight reduction. Moreover, the printing which used the shrink film, for example can also be provided to the outer surface of the container main body 21.

  In order to perform a hair dyeing treatment using a hair coloring product, first, the main package 11 and the secondary package 12 are taken out from the container body 21, and each package 11, 12 is opened. As shown in b), each agent is put into the container body 21. Subsequently, as shown in FIG. 1C, the lid body 22 is attached to the container main body 21, and the occluding container 20 is shaken up and down. At this time, in the closable container 20, air is mixed into the oxidative hair dye by mixing each agent and shaking the oxidative hair dye which is a mixture of each agent up and down. Thus, the foaming of the oxidative hair dye is started by the operation of shaking the air into the oxidative hair dye. Then, the foaming operation is completed by shaking the closable container 20 a predetermined number of times. By this foaming operation, a foam-like oxidative hair dye 14 shown in FIG. 1 (d) is prepared from the oxidative hair dye 13 before foaming shown in FIG. 1 (b). Subsequently, the foam-like oxidative hair dye 14 is taken out by hand, for example, and applied to the hair. At this time, since the oxidative hair dye is foamy, it can be easily adapted to the hair. The hair is dyed by leaving the hair coated with the oxidative hair dye for a predetermined time. Subsequently, the hair dyeing treatment is completed by washing away the oxidative hair dye on the hair with water or warm water.

  Here, the container main body 21 is configured to have a bottomed cylindrical shape whose opening is larger than the bottom wall thereof, so that the oxidative hair dye can be easily taken out by hand, for example. Further, the inner surface of the container body 21 has a curved surface, so that, for example, when the oxidative hair dye is taken out by hand, the oxidative hair dye hardly remains on the inner surface of the container body 21.

  The ratio (mL / g) of the content (mL) of the closable container 20 to the mass (g) of the oxidative hair dye is preferably in the range of 2-15. When the ratio (mL / g) is 2 or more, when the above shaking operation is performed, the amount of movement of the oxidative hair dye in the closable container 20 is easily secured, so the air to the oxidative hair dye The mixing of will be promoted. As a result, it is possible to reduce the number of shakings until the oxidative hair dye is sufficiently foamed. On the other hand, when the ratio (mL / g) exceeds 15, after the foaming operation of the oxidative hair dye is completed, the excess space in the closable container 20 is increased, so that the oxidative hair dye 14 after foaming is reduced. There is a risk that it will be difficult to remove.

In the said foaming, it is preferable to foam so that it may become the range of 2-13 mL per gram of oxidative hair dye, and it is more preferable to foam so that it may become the range of 3-10 mL.
According to the embodiment described in detail above, the following effects are exhibited.

  (1) The oxidative hair dye of this embodiment contains an amphoteric surfactant and an anionic surfactant, and the mass ratio of the amphoteric surfactant to the anionic surfactant is 0.8 to 8.0. It is a range. Thereby, it becomes easy to obtain a dosage form that hardly scatters when applied to hair through foaming by shaking, is well-familiar with hair, and does not sag from hair. As a result, it is possible to provide an easy-to-handle oxidative hair dye from the application stage of the oxidative hair dye to the stage of leaving the oxidative hair dye applied to the hair for a predetermined time.

  (2) Since the oxidative hair dye does not contain a cationic surfactant, it can be made more difficult to scatter when applied to hair. In addition, for example, when a cationic surfactant is included in order to enhance the feel of hair, the content of the cationic surfactant in the oxidative hair dye is in the range of 1% by mass or less, and the cationic surfactant is used. It is preferable to contain a mass ratio of the anionic surfactant to the agent of 1.2 or more. Thereby, even if it contains a cationic surfactant, it becomes possible to obtain a dosage form that hardly scatters when applied to hair.

  (3) In an oxidative hair dye, an anionic surfactant is effective in order to make it easy to remove the dye adhering to the background. In this regard, the effect can be remarkably obtained by containing an anionic surfactant in the oxidative hair dye, for example, 0.1% by mass or more, more preferably 0.3% by mass or more. Thus, in the oxidative hair dye containing an anionic surfactant, the constitution in which the mass ratio of the amphoteric surfactant to the anionic surfactant is in the range of 0.8 to 8.0 is a stain due to a background dye. It is extremely advantageous because the dosage form described in the above (1) can be obtained.

  (4) In the said embodiment, the oxidation hair dye is made to foam by operation which shakes and mixes air to an oxidation hair dye. Since such a foaming operation is an easy-to-understand operation that does not require skill, it can be easily foamed and can be enjoyed. Further, without using a container having a complicated structure such as a former container, the container can be foamed by a closable container, for example. For this reason, it is advantageous in that the foaming operation can be performed with extremely simple foaming tools such as a container body and a lid.

  (5) The hair coloring product of the present embodiment includes the above-described oxidative hair dye and a closable container. According to such a hair dyeing product, it is possible to easily carry out a foaming operation of making a foamy dosage form by an operation of shaking and mixing air into the oxidative hair dye. Therefore, the user can easily prepare a foamy oxidative hair dye.

In addition, the said embodiment can also be changed and comprised as follows.
-Although the hair cosmetic composition of the said embodiment is comprised as an oxidative hair dye, according to a conventional method, you may comprise as an acidic hair dye as a hair dye, and as a hair decoloring and decoloring agent. It may be configured. Even in this case, the effects described in the columns (1), (2), (4), and (5) can be obtained.

Moreover, when comprised as an acidic hair dye, the effect described in the said (3) column can be acquired.
Hereinafter, unless otherwise specified, it is meant that the hair cosmetic composition contains a hair dye and a hair bleaching / destaining agent. In the case of constituting as a hair bleaching / destaining agent, it can be changed in the same manner as the oxidative hair dyeing agent except that it does not contain a dye for dyeing hair.

  -You may comprise so that at least one part of the water contained in the said oxidation hair dye may be separately mixed with respect to a main ingredient and an auxiliary agent at the time of use. However, from the viewpoint of prompt foaming by the foaming operation, at least the amphoteric surfactant is preferably dissolved in a solvent containing water.

  -Although the said oxidation hair dye is comprised from the main ingredient and an auxiliary agent, according to a conventional method, the oxidation hair dye comprised from the 1st agent containing a dye and an alkaline agent, and the 2nd agent containing an oxidizing agent You may change to an agent. In this case, the first agent is not limited to a solid state, and may be, for example, an aqueous solution, a dispersion, an emulsion, a gel, or a cream. As the alkali agent contained in the first agent, for example, ammonia and alkanolamine can be used in addition to the specific examples. As the oxidizing agent contained in the second agent, for example, hydrogen peroxide water can be used.

  The oxidative hair dye is composed of a main agent and an auxiliary agent, and at least one agent is divided into a plurality of agents, and the plurality of agents are mixed at the time of use. Also good. In the case of an acid hair dye, it can also be set as the composition of one agent.

  The foaming operation can be changed as follows. That is, a foaming operation in which air is mixed into the hair cosmetic composition by applying vibration to the hair cosmetic composition, or air is mixed into the hair cosmetic composition by adding rotation to the hair cosmetic composition. It can also be changed to a foaming operation. That is, the foaming operation of foaming by shaking the hair cosmetic composition is an operation of shaking and mixing the hair cosmetic composition, an operation of applying vibration to the hair cosmetic composition, and an operation of rotating the hair cosmetic composition. It means that it is made to foam by at least one kind of operation.

  Depending on the type of foaming operation, the foaming tool for foaming the hair cosmetic composition can be changed. For example, in the case of a foaming operation in which vibration is mainly applied, as the foaming tool, for example, a vibration exciter and a manual type whisk are suitable.

As a result, excellent ones with no scattering (5 points), good ones with very little scattering (4 points), acceptable ones with little scattering (3 points), and slightly poor ones with little scattering (2 points) And those with much scattering were scored in 5 stages of bad (1 point). The average value of scoring results of each paneler is calculated, and if the average value is 4.6 points or more, “Excellent: 5”, 3.6 points or more and less than 4.6 points are “Good: 4”, 2.6 points or more 3 Less than 6 points are judged as “possible: 3”, 1.6 points to less than 2.6 points as “slightly bad: 2”, and 1 point and less than 1.6 points as “bad: 1”. An evaluation of the effect of suppressing the above was made.

  Regarding the effect of ease of adaptation to hair, first, 20 panelists visually observed the state in which the foamy hair dye penetrated between the hairs during the work of applying the foamy hair dye to the hair. confirmed. As a result, excellent penetration is very good (5 points), fast penetration good (4 points), easy penetration (3 points), slow penetration slightly poor (2 points), And what was difficult to permeate and stayed on the hair was scored in 5 stages of poor (1 point). The average value of the scoring results of each paneler was calculated, and the effect of the familiarity with hair was evaluated according to the above criteria based on the average value.

  Regarding the effect of difficulty in dripping, first, 20 panelists applied the foam-like oxidative hair dye to the hair and visually confirmed the movement of the foam for 30 minutes. As a result, excellent foams that do not move (5 points), good that the bubbles move slightly (4 points), those that move a little (3 points), those that move slightly larger Slightly poor (2 points) and those with large bubble movement were scored in 5 stages: defective (1 point). An average value was calculated for the scoring results of each paneler, and the effect of difficulty in dripping was evaluated according to the above-described determination criteria based on the average value.

  Using the oxidative hair dye of each example, it was applied to the hair of 20 panelists so that the oxidative hair dye adhered to the scalp, and then allowed to stand at room temperature (25 ° C.) for 30 minutes. Then, the oxidative hair dye attached to the hair was washed away with water, and the hair was shampooed twice and rinsed once. Subsequently, after the hair was dried with warm air, it was left for one day to obtain hair that had been dyed. About the scalp after a hair dyeing | staining process, 20 panelists evaluated whether the skin stain | pollution | contamination prevention effect was high by evaluating the stain | pollution | contamination condition of skin visually under a standard light source.
