  In addition, content of the inorganic salt in an oxidative hair dye is from a viewpoint of exhibiting the effect which maintains a foamy dosage form more by (A) anionic surfactant and (B) cationic surfactant. It is preferable that it is 10 mass% or less.

  The method of using the oxidative hair dye comprises (A) an anionic surfactant and (B) a contacting step in which the cationic surfactant is brought into contact, and a foaming step in which foaming is performed after the contacting step into a foamy dosage form. Contains. As shown in FIG. 1 (a), the contacting step and the foaming step in the present embodiment are carried out using a closable container 20 that allows the oxidative hair dye to be liquid-tightly closed.

  The closeable 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 first agent package 11 and the second agent package 12 can be accommodated. In such a closable container 20, each container can be stored together by using the container 20 as an exterior container of the oxidative hair dye 10. The packaging form of each agent is not particularly limited, and examples thereof include bottle packaging, pillow packaging, and tube packaging. 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.

  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.

  In order to use an oxidative hair dye using such a closable container 20, first, the first agent package 11 and the second agent package 12 are taken out from the container body 21, and each package 11, 12 is removed. After opening, each agent is put into a container capable of being closed as shown in FIG. 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 stage is completed by shaking the closable container 20 a predetermined number of times. By this foaming step, a foamy oxidative hair dye is prepared. That is, in the foaming stage, the foamy hair dye 14 shown in FIG. 1 (d) is prepared from the hair dye 13 before foaming shown in FIG. 1 (b).

  Here, since the (A) anionic surfactant and the (B) cationic surfactant are contacted when the oxidative hair dye is used, the foaming action of the (A) anionic surfactant is (B) It is presumed that it is not influenced by the cationic surfactant and (A) the original foaming action as the anionic surfactant is easily exhibited. Moreover, in the foaming stage, it is presumed that the film constituting the foam is strengthened by the interaction of (A) the anionic surfactant and (B) the cationic surfactant. Thus, the oxidative hair dye made into a foam-like dosage form is in a state where it is difficult to defoam (break).

  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. The hair dyeing step is then completed by washing the oxidative hair dye with water or warm water.

  The oxidative hair dye of the present embodiment is provided as a hair dyeing product together with the above-described occlusive container, thereby simplifying the foaming operation of forming a foamy dosage form by shaking air into the oxidative hair dye. Can be implemented.

According to the embodiment described in detail above, the following effects are exhibited.
(1) Foaming with a non-aerosol can form a foam without using a propellant, but tends to form bubbles that are easily defoamed over time. That is, by exhibiting the foaming power of (A) the anionic surfactant, the foaming ability is enhanced, but the maintenance power for maintaining the foamy dosage form is hardly exhibited. Here, if the anionic surfactant and the cationic surfactant are brought into contact with each other in advance, the cationic surfactant may interfere with the foaming force of the anionic surfactant. Foam strength is difficult to be demonstrated. In this regard, the first agent and the second agent of the present embodiment have a configuration in which (A) an anionic surfactant and (B) a cationic surfactant are divided so as to be contacted at the time of use. For this reason, in the foaming stage, the foaming power of (A) anionic surfactant is easily exerted, and (A) the anionic surfactant and (B) the cationic surfactant are used to eliminate the defoaming. It will be in a state where it is difficult to (break). Therefore, it is possible to provide an oxidative hair dye that enhances foamability and can easily maintain a foamy dosage form.

(2) When the mass ratio of (A) anionic surfactant to (B) cationic surfactant is in the range of 0.25 to 3, the foamy dosage form is more easily maintained.
(3) It is preferable that the oxidative hair dye contains (C) an amphoteric surfactant. In this case, even if it is foaming by non-aerosol, it becomes easy to improve foamability.

  (4) The method of using the oxidative hair dye of the present embodiment includes (A) an anionic surfactant and (B) a cationic surfactant in contact with each other, and a foamy dosage form after the contacting step. And a foaming step for foaming. According to this method, since the effect described in the above section (1) can be obtained, there is provided a method for using an oxidative hair dye that can easily maintain a foamy dosage form in foaming with a non-aerosol. Is done.

  (5) In the method for using the oxidation hair dye of this embodiment, the foaming operation in the foaming stage is an operation of shaking and mixing air into the 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.

  (6) 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.
The oxidative hair dye is configured as a two-part oxidative hair dye, but at least one of the agents is divided into a plurality of agents, and the plurality of agents are mixed at the time of use. You may comprise. For example, an agent containing one of (A) an anionic surfactant and (B) a cationic surfactant can be configured as a separate agent from the first agent and the second agent. Thus, (A) anionic surfactant and (B) cationic surfactant are comprised as a several agent divided | segmented so that it may be contacted at the time of use, and foamability is improved in foaming by a non-aerosol At the same time, it becomes easy to maintain a foamy dosage form.

  -Although the hair cosmetic composition of the said embodiment is comprised as an oxidation hair dye, according to a conventional method, it can also be comprised as an acidic hair dye or a decoloring decoloring agent. Even in this case, it is easy to maintain a foamy dosage form in foaming by non-aerosol. Hereinafter, unless otherwise specified, it is meant that the hair cosmetic composition contains a hair dye and a hair decoloring decoloring agent.

- as a reference example, in addition to foam the hair cosmetic composition by closable vessel, examples Ru by foaming hair cosmetic composition by former vessel and the like. Examples of the former container include a pump former and a squeeze former.

  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. Further, for example, in the case of a foaming operation in which rotation is mainly applied, for example, a stirrer, a stirrer, and an electric whisk are suitable as the foaming tool. Such foaming operation is performed in the container by putting the hair cosmetic composition into, for example, a container having an opening at the upper end.

Thus, foaming by shaking the hair cosmetic composition without using the former container makes it easy to maintain the foamed dosage form even when the foamed dosage form is used. .
-You may comprise a hair-cosmetics composition so that it may become a foam form with a non-aerosol at the time of use by containing a nonionic surfactant, for example, without containing an amphoteric surfactant. Here, in the case of a hair cosmetic composition to be foamed by shaking, the effect of increasing foaming properties is remarkably exhibited by containing an amphoteric surfactant. In this regard, it is particularly preferable that the hair cosmetic composition foamed by shaking contains an amphoteric surfactant.

  -A small amount of cationic surfactant in the agent containing (A) anionic surfactant as long as the action and effect of (A) anionic surfactant and (B) cationic surfactant are exhibited. An agent may be contained, or a small amount of an anionic surfactant may be contained in the agent containing the (B) cationic surfactant. However, from the viewpoint of remarkably exhibiting the effects of (A) anionic surfactant and (B) cationic surfactant, (A) the agent containing an anionic surfactant is a cationic surfactant. It is preferable that the composition containing no cationic surfactant and the agent containing the (B) cationic surfactant be constructed without containing the anionic surfactant.

  ・ When both (A) anionic surfactant and (B) cationic surfactant are solid, they are contained in the same agent so that they are contacted in the presence of a solvent at the time of use. It may be a solid agent. This solid agent is contacted in the solvent of these surfactants at the time of use. As the solvent, water or a mixed solvent of water and alcohol is suitable. As alcohol, C2-C4 alcohol is mentioned, for example. Thus, (A) anionic surfactant and (B) cationic surfactant are comprised so that it may contact in presence of a solvent at the time of use, and it is the same as the effect as described in the said (1) column. The effect of this can be obtained.

  -Although the said container main body is formed in bottomed cylindrical shape, it can also be changed into bottomed prismatic shape, for example. Moreover, you may change suitably also about the shape of a cover body, for example according to the shape of a container main body.

  -It is formed in the said occluding container so that the 1st agent and the 2nd agent can be accommodated in the state packaged separately. That is, although the occluding container is used as the exterior of each agent, at least one of the agents may be stored outside the occluding container.

  In the above embodiment, air is shaken and mixed in the hair cosmetic composition by shaking the occlusive container up and down. For example, the operation of shaking the occlusive container by grasping the occlusive container and twisting the wrist Thus, air may be shaken and mixed into the hair cosmetic composition.

Next, the technical idea that can be grasped from the above embodiment will be described below.

Next, the embodiment will be described more specifically with reference to examples and comparative examples.
(Examples 1-8 and Comparative Examples 1-4)
In each example, a two-component oxidative hair dye was prepared by mixing the components shown in Tables 1 and 2. The unit of the numerical value which shows the compounding quantity of each component in Table 1, Table 2, and the following table | surface is the mass%. In addition, although the dosage form of the 1st agent is a powder form and the dosage form of a 2nd agent is a liquid, the dosage form of each agent is not specifically limited.

  Next, foaming operation of the oxidative hair dye of each example was performed using the container which can be closed. The capacity of the closable container is 770 mL, the height is 17 cm, and the inner diameter is 7 cm to 8 cm. Each agent was put into the closable container so that the mixture of the first agent and the second agent was 150 g, and the closable container was shaken up and down 20 times. A foamy dosage form was obtained by performing a foaming operation in which air was shaken and mixed with such an oxidative hair dye.

(Examples 9 to 24)
In each Example, as shown in Table 3 and Table 4, it is the same as Example 1 except having changed the compounding quantity about at least one of (A) anionic surfactant and (B) cationic surfactant. Thus, a foamy dosage form was obtained.

<Foaming properties>
About the oxidation hair dye of each case, the specialized panelist observed the foaming state after foaming operation visually. The result was determined according to the following criteria.

Evaluation 5: The amount of foaming is very excellent.
Evaluation 4: The amount of foaming is excellent.
Evaluation 3: The amount of foaming is good.

Evaluation 2: The amount of foaming is slightly inferior.
Evaluation 1: The amount of foaming is inferior.
The numerical value of the judgment result is shown in the “Evaluation of foamability” column of each table.

<Evaluation of dosage form maintenance power>
About the oxidative hair dye of each case, the specialized panelist observed the temporal change for the foaming state after foaming operation visually. As a result, the case where almost no defoaming (breaking bubbles) was observed after 10 minutes from immediately after the foaming operation was evaluated as 5. A rating of 4 indicates that about 20% of defoaming (breaking bubbles) is confirmed after 10 minutes, and an evaluation of 3 indicates that about 10% of defoaming (breaking) is confirmed after 10 minutes. The thing was evaluated as 2, and the thing in which about 40% of defoaming (bubble breakage) was confirmed after 10 minutes passed was rated as 1. The numerical values of the judgment results are shown in the “Evaluation of dosage form maintenance power” column of each table.
