Description

Hair cosmetic composition

The invention disclosed by the present application relates to a hair cosmetic composition. Specifically, the present invention relates to a hair cosmetic composition in which a plurality of agents are mixed and shaken to foam.

Generally, as a hair cosmetic composition, an oxidation hair dye, a decoloring agent and a decoloring decoloring agent comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent are known. .

Conventionally, liquid or cream-like hair cosmetic compositions have been used. However, there is little fear of dripping and the application property to the hair and the feeling of use are excellent. Things have increased.

Various means for obtaining a foamed dosage form are known. For example, an aerosol type using a liquefied gas such as LPG, a type using a non-aerosol foamer container, a type using a container to shake and foam (a carbon dioxide gas) Including the case of stirring operation using generation).

The following Patent Document 1 discloses a hair cosmetic composition in which a powdery agent and a liquid agent are mixed and shaken to obtain a foamy dosage form. The hair cosmetic composition disclosed in Patent Document 1 below is advantageous in that the disposal of the can body is unnecessary for the aerosol type. Further, since the foam formed by shaking is small, the foam homogenizing means is unnecessary, and the operation of mixing foaming is further simplified. Moreover, the foamy hair cosmetic composition obtained by shaking also had good holding power on the hair.

The following Patent Document 2 discloses a hair dyeing or decoloring kit that can be made into a foamy dosage form without using a container having a complicated structure such as an aerosol container or a non-aerosol container.

As described above, the foam-type hair cosmetic composition has various advantageous aspects. In particular, improvements in hair cosmetic compositions disclosed in the following Patent Document 1 and Patent Document 2 in which the foaming operation is simplified are progressing. And various prescriptions of the 1st agent which mix | blends the alkaline agent and the 2nd agent which mix | blends an oxidizing agent suitable for obtaining a foamy dosage form simply are disclosed.

A representative oxidizing agent contained in the second agent is hydrogen peroxide. For example, the following Patent Document 1 (Table 3 etc.) and Patent Document 2 (Paragraph 0101) describe a second agent containing hydrogen peroxide.

JP 2011-105620 A JP 2011-184428 A

The inventor of the present application observed a production test of a hair cosmetic composition with a simplified foaming operation. Unexpectedly, in the production of the second agent containing hydrogen peroxide, a production facility made of metal such as stainless steel was used. It has been found that rust may be generated. Therefore, the present inventor considered that there is some cause in the prescription of the second agent suitable for obtaining a foamy dosage form simply.

The inventor of the present application first studied by paying attention to the viscosity of the second agent containing hydrogen peroxide. And when the viscosity was made high by mix | blending a higher alcohol with the 2nd agent which produces rust in metal manufacture facilities, such as stainless steel, it discovered that generation | occurrence | production of rust can be suppressed. From this result, it was thought that generation | occurrence | production of rust can be suppressed by the mixing | blending of the higher alcohol to a 2nd agent and / or the raise of the viscosity of a 2nd agent.

Next, as a result of earnest research on the rust generated, the present inventor has found that amphoteric surfactants (coconut oil fatty acid amidopropyl betaine, etc.), cationic surfactants (stearyltrimethylammonium chloride, etc.), and cationic polymers (polydimethyl chloride). It came to be considered that halide ions which are counter ions of methylenepiperidinium and the like) increase the rust.

On the other hand, as disclosed in Patent Document 1, the amphoteric surfactant is a useful component for improving the operability of mixed foaming, obtaining good foaming, and fine foam. In addition, both the cationic surfactant and the cationic polymer are useful components for improving the operability of mixed foaming, improving touch, and improving foaming.

From the above, in order to suppress the rust generated in the production of the second agent containing hydrogen peroxide, increase the higher alcohol content of the second agent, increase the viscosity of the second agent, or amphoteric surfactant, It is only necessary to reduce the compounding amount of the cationic surfactant and the cationic polymer, and to reduce the compounding amount of the halide ion which is the counter ion. However, there is a concern that the defoaming action becomes apparent when the amount of the higher alcohol in the second agent is excessive. Further, it is considered that the higher the viscosity of the second agent, the more difficult it is to make the hair cosmetic composition foam. Also, if the amount of amphoteric surfactant, cationic surfactant, and cationic polymer is reduced, it will be difficult to obtain good foam with a simple operation of shaking, and there will also be a problem in touch. It is thought that it will end.

As a result of earnest research to obtain good foaming and feel while suppressing the generation of rust in the production facility, the inventors of the present application have obtained a combination of specific surfactants, a chelating agent, and a cationic substance. The invention disclosed by the present application has been completed by finding that the identification and the like are effective.

Therefore, it is an object to be solved by the present application to provide a hair cosmetic composition that can suppress the generation of rust in the production equipment for the second agent containing hydrogen peroxide and can obtain good foaming and feel. .
