  The present invention relates to a hair cosmetic and a hair cosmetic product. More specifically, the present invention relates to a hair cosmetic comprising a first agent and a second agent, which is foamed at the time of use, and a hair cosmetic product comprising the hair cosmetic and a non-aerosol foamer container.

  Conventionally, a hair dye (for example, an oxidative hair dye, a hair bleaching agent) that is configured in a two-part type or a three-part type including the first agent and the second agent and that is foamed when used (when mixing each agent) Hair decoloring agents) and the like have been proposed. If the hair dye is made foamy at the time of use, the hair dyeing operation on the back of the head and the like can be easily performed, and it is difficult to cause uneven hair dyeing and uneven coloring.

  An aerosol foam container or a non-aerosol foam container is used as a foam container for foaming these hair cosmetics when used.

JP 2010-6803 A Japanese Patent Application Laid-Open No. 2011-207821 JP 2011-93824 A

  By the way, in general, hair cosmetics are required to have a good feel (good touch and good finger feeling) of the hair after treatment. In particular, hair dyes are required to have a good feel to the hair when the drug is washed away. In order to give a good feel to the hair, as is well known, it is effective to add a cationic substance, particularly a cationic polymer, to the hair cosmetic.

  However, in a two-component hair dye, surprisingly, when a prescription is made by blending a cationic polymer with a second agent containing an oxidizing agent (particularly hydrogen peroxide), stainless steel used for the production of the second agent The knowledge that rust may be produced in metal manufacturing facilities, such as these, was acquired.

  According to this knowledge, it is preferable to mix a cationic polymer with the first agent. However, when a cationic polymer is blended with the first agent, the first agent is usually adjusted to be alkaline, so that the ionicity of the cationic polymer is weakened and it is difficult to dissolve a sufficient amount (first) Issue).

  On the other hand, when the hair cosmetic such as a hair dye is made into a foam using a non-aerosol foam container, the foam container is a method of passing the hair cosmetic through a fine mesh to make it foam. The solution for the first problem should not cause problems such as clogging of the mesh in the non-aerosol foamer container (second problem).

  Therefore, the present invention relates to a hair cosmetic comprising a first agent and a second agent, which is foamed at the time of use, in particular, a hair cosmetic which is foamed using a non-aerosol foamer container at the time of use. The object is to solve the problem and further to solve the second problem.

(Configuration of the first invention)
The structure of the first invention of the present application for solving the above-mentioned problem is a hair cosmetic comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent, which is foamed at the time of use. One agent is a hair cosmetic containing (A) one or more amphoteric surfactants and (B) one or more cationic polymers.

(Configuration of the second invention)
The constitution of the second invention of the present application for solving the above problem is that in the hair cosmetic composition according to the first invention, (A) the amphoteric surfactant is composed of sodium β-laurylaminopropionate and sodium laurylaminodipropionate. It is a hair cosmetic, which is an amphoteric surfactant containing at least one selected.

(Configuration of the third invention)
The configuration of the third invention of the present application for solving the above-mentioned problems is a hair cosmetic in which the hair cosmetic according to the first invention or the second invention is foamed using a non-aerosol foamer container. .

(Configuration of the fourth invention)
The structure of the fourth invention of the present application for solving the above problem is that in the hair cosmetic composition according to any one of the first to third inventions, the first agent is further one or both of the following (C) and (D): It is a hair cosmetic containing the ingredients of

(C) Paraaminophenol and / or resorcin which is a dye component (D) One or more of chelating agents (Structure of the fifth invention)
The structure of the fifth invention of the present application for solving the above-mentioned problems is a hair cosmetic product comprising the hair cosmetic according to any one of the first to fourth inventions and a non-aerosol foamer container. is there.

(Effect of the first invention)
According to the first invention, in the hair cosmetic that includes the first agent containing the alkaline agent and the second agent containing the oxidizing agent and is foamed at the time of use, the cationic polymer is basically the component (B). Is blended into the first agent, so that it is possible to avoid such a problem that rust is produced in a metal production facility such as stainless steel used for producing the second agent as described above.

  And in 1st invention, the amphoteric surfactant which is (A) component is mix | blended with the 1st agent with (B) cationic polymer. In this case, the amphoteric surfactant having a relatively strong anionic property in the alkaline first agent forms a complex with the cationic polymer. The formation of the complex weakens the hair feel improvement effect inherent to the cationic polymer, but the amphoteric surfactant and the cationic polymer offset each other's ionicity, resulting in the complex acting like an oily component and the hair. Compensate the feel improvement effect.

  Thus, in 1st invention, the said 1st subject at the time of mix | blending a cationic polymer with the 1st agent of hair cosmetics, such as a hair dye, is solved, and also the hair feeling improvement effect by a cationic polymer is combined. Is also compensated.

(Effect of the second invention)
In the first invention described above, the complex of the amphoteric surfactant and the cationic polymer tends to generate a complex aggregate that can be visually recognized as turbidity due to the large molecular weight of the latter. This turbidity is not preferred when it is desired to make the first agent into a highly transparent aqueous solution, and as a larger problem, when the hair cosmetic is foamed using a non-aerosol foamer container, this turbidity There is a risk of clogging the mesh of the container (second problem).

  However, in the second invention, an amphoteric surfactant containing at least one selected from sodium β-laurylaminopropionate and sodium laurylaminodipropionate is used as the amphoteric surfactant which is the component (A). When such an amphoteric surfactant was used, it turned out that the turbidity based on formation of the above complex aggregates can be suppressed notably.

  Therefore, according to the second aspect of the invention, the hair cosmetic does not cause the clogging of the mesh of the non-aerosol foamer container, and the second problem is solved.

(Effect of the third invention)
From the points described above, as in the third invention, the hair cosmetic composition of the present invention can be preferably foamed using a non-aerosol foamer container at the time of use.

(Effect of the fourth invention)
As specified in the fourth invention, the blending of the chelating agent as component (D) is also preferred from the viewpoint of improving the formulation stability in hair cosmetics. In addition, in hair cosmetics that are hair dyes, paraaminophenol (main intermediate) and resorcin (coupler) as component (C) are often blended in the first agent. These compounding components also contribute to the turbidity of the first agent due to bonding with the cationic polymer.

  However, when the specific amphoteric surfactant specified in the second invention is added to the first agent, such turbidity can be effectively prevented.

(Effect of the fifth invention)
According to 5th invention, the preferable hair cosmetics article comprised including the hair cosmetics and non-aerosol foamer container which concern on 1st invention-4th invention are provided.

  Next, modes for carrying out the present invention will be described including the best mode.

[Evaluation of hair cosmetics]
(Hair feel)
Non-aerosol foamer containers (pumps) of the first agent and the second agent of the hair dye according to the combination as described above in Examples 1 to 13 and Comparative Examples 1 to 5 at a mass ratio of 1: 1. The mixture was contained in a former to form a mixed solution, and the pump head was pressed to discharge the mixed solution in a foam form. As the pump former, trade name W-5721 manufactured by Yoshino Kogyo Co., Ltd., WP former pump L nozzle type (gas / liquid mixing ratio: 13/1, discharge amount: 0.9 g (1 push), porous Material film: two 90-mesh polyethylene mesh rings) were used.

  Each of these foam-type hair dyes was uniformly applied to a white hair bundle sample and allowed to stand for a predetermined time for hair dyeing treatment. Thereafter, the foamy hair dye was washed away, and the feel of the hair bundle sample at that time was evaluated by touch by five panelists. Evaluation was performed by the following five-level ranking. When the evaluations of each panel did not agree, a relatively large number of evaluation ranks were adopted. When relatively many evaluation ranks were broken into two or more, the worse evaluation rank was adopted.

  5: Very smooth and does not entangle with fingers.

  4: Smooth and does not entangle with fingers.

3: Slightly smooth and almost entangled with fingers 2: Slightly squeaky with little finger entanglement.

  1: There is a squeak and the entanglement with a finger is conspicuous.

  The results of the above evaluation are shown in the “feel” column in the “evaluation” section of Tables 1 to 3. As a result of the evaluation, when the foam hair dye according to each example was used, the evaluation result was much better than those of Comparative Examples 1 and 3.

(Rust control)
Evaluation of rust suppression was performed using the second agent of the hair dye according to Examples 1 to 13 and Comparative Examples 1 to 5. That is, each half of the JIS standard SUS test piece (made of stainless steel) is immersed in the second agent in the non-foamed state according to each of the examples and comparative examples, and the following “◯” or “×” On the basis of the evaluation criteria, the presence or absence of rust on the test piece was evaluated.

  ○: The test piece does not rust even after one week at 30 ° C.

  X: Rust occurs on the test piece within 30 minutes at 30 ° C.

  The results of the above evaluation are shown in the “rust prevention” column in the “evaluation” section of Tables 1 to 3.

(Foam quality)
The first agent and the second agent of the hair dye according to the combination as described above in Examples 1 to 13 and Comparative Examples 1 to 5 are mixed in a non-aerosol foamer container (“ The mixture was contained in a pump former used in the evaluation of “hair feel” to obtain a mixed solution, and the mixed solution was discharged in a foam form by pressing the pump head part. And five panelists evaluated the foam quality immediately after discharging by visual observation. Evaluation was performed according to the following three ranks. When the evaluations of each panel did not agree, a relatively large number of evaluation ranks were adopted. When relatively many evaluation ranks were broken into two or more, the worse evaluation rank was adopted.

  (Double-circle): The texture of foam is in order and it is a bulky foam.

  A: The foam is slightly rough and lacks in height.

  X: Bubbles that are slightly watery and lack bulkiness.

(Formulation stability)
The first agents of the hair dyes according to Examples 1 to 13 and Comparative Examples 1 to 5 prepared as described above were transferred to a transparent glass bottle immediately after the preparation, respectively, and 24 under a constant temperature cycle. The mixture was left standing in a cool and dark place for a while and the occurrence of turbidity was visually observed.

  Specifically, immediately after standing in a dark place for 24 hours under the condition of a temperature increase / decrease cycle of -5 ° C to 5 ° C (2 cycles for 24 hours) and immediately after being left for 6 hours at room temperature (25 ° C). The presence or absence of turbidity was evaluated. The evaluation was performed by the following three ranks. In this ranking, “immediately” means immediately after standing in a dark place for 24 hours under the above temperature raising and lowering cycle, and “aging” means immediately after being left for 6 hours at the above room temperature.

  A: There was no turbidity immediately after.

  ○: Immediately after turbidity, the turbidity disappeared over time.

  X: It became cloudy immediately after, and the cloudiness did not disappear even with time.

The results of the above evaluation are shown in the column “Formulation stability” in the “Evaluation” section of Tables 1 to 3. As a result of the evaluation, the first agent according to Comparative Example 1 was turbid, but the first agent according to each Example was not turbid.

  According to the present invention, there is provided a hair cosmetic having a good touch-improving effect in which a cationic polymer is well dissolved in a first agent such as a hair dye.
