Description

  The present invention relates to a hair dye, a method for using the same, and a hair dye article. More specifically, the present invention includes a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and the mixture of the first agent and the second agent is foamed from a non-aerosol foamer container. A hair dye which is used by being discharged onto the hair, and does not reduce the foam specific gravity even if it is swallowed by hand when applied to the hair, a method of using this hair dye on the hair, and this hair dye and The present invention relates to a hair dye product comprising a non-aerosol foamer container.

  Conventionally, it is composed of a multi-agent type such as a two-component type or a three-component type including a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and is made into a dosage form such as cream or gel. Hair dyes such as hair dyes, hair depigmenting agents and hair depigmenting agents are known. These hair dyes are used for hair dyeing treatment by applying a mixture of the respective agents to the hair using a comb or a brush. However, since these hair dyes have a high viscosity, it is possible to effectively prevent dripping of the liquid during the hair dyeing treatment time, but it is difficult to apply them uniformly to the entire hair. In particular, it is difficult for the user's own back of the head or the like to uniformly apply the hair dye even if a mirror is used. In addition, it takes time and effort such as so-called hair blocking.

  On the other hand, hair dyes that use each agent mixture of multi-component hair dyes in the form of foam have been proposed. With these hair dyes, the discharged foam can be applied to the entire hair as if it were swallowed by hand. For example, the following Patent Documents 1 and 2 disclose hair dyes that are applied to hair by being ejected in a foam form with an aerosol-type foamer container, and the following Patent Documents 3 to 5 include a pump former, a squeeze foamer, and the like. A hair dye that is applied to hair by being discharged in the form of foam in a non-aerosol type former container is disclosed.

  By the way, the hair dye used in the foamy dosage form has the advantage that it can be applied to the entire hair as described above, but in general, the hair dye tends to be insufficient, and the hair dye from the hair of the hair dye There is a problem that dripping is easy to occur. In the present specification, the term “dye” or “dye” refers to the decoloring effect for the hair decoloring agent and the decoloring effect for the hair decoloring agent, respectively.

  Regarding the above problem, it is conceivable to improve the dyeing of the hair by increasing the fineness of the foam in the foamy hair dye to improve the adhesion to the hair. Here, the “fine bubbles” are bubbles having a large liquid ratio in the volume ratio of liquid and gas constituting the bubbles, and the specific gravity of the bubbles is relatively large.

  However, due to the structural limitations of the non-aerosol foamer container, there is a limit to ejecting such fine bubbles depending only on the function of the non-aerosol foamer container.

  On the other hand, when a highly foaming surfactant is blended in the hair dye to make the foam fine, fine foam can be discharged from the non-aerosol foamer container. However, when the discharged foam is swallowed by hand and applied to the hair, the foam takes in air due to the highly foaming surfactant, resulting in coarse foam (low foam specific gravity). . Therefore, the dyeing of the hair dye cannot be improved, and there is a risk that the lightness of the foam may lead to dripping of the foamy hair dye.

  Therefore, the present invention can discharge a foam having a large specific gravity (fine texture) using a non-aerosol foamer container, and the foam specific gravity is lowered even if an operation such as swallowing is applied to the hair. Providing an undyed hair dye is a problem to be solved.

  The inventor of the present application has conducted experimental research on various prototypes of hair dyes, and as a result, in the hair dye for non-aerosol foamer containers, “gas: liquid = 13: 1 The ratio Y / X between the foam specific gravity (X) immediately after discharged from the non-aerosol foamer container and the foam specific gravity (Y) immediately after stirring the foam immediately after the discharge under specific stirring conditions is 0.75 to 0.75. The inventors have found that satisfying the condition “within the range of 2” is a means for solving the above problem, and the present invention has been completed.

(Configuration of the first invention)
The structure of the first invention of the present application for solving the above-mentioned problem is configured to include a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and a mixed solution of each agent is removed from a non-aerosol foamer container. A hair coloring agent used by being discharged in the form of foam, the foam specific gravity (X) immediately after being discharged from a non-aerosol foamer container having a gas-liquid mixing ratio of gas: liquid = 13: 1, and bubbles immediately after the discharge Is a hair dye in which the ratio Y / X to the foam specific gravity (Y) immediately after stirring under specific stirring conditions is in the range of 0.75 to 2.

  In the first invention, “gas / liquid = 13: 1 gas / liquid mixing ratio” defines a standard gas / liquid mixing ratio of a former container used for numerical determination of the ratio Y / X. It is not stipulated that the foam container having this gas-liquid mixing ratio should be used in actual use of the hair dye according to the invention.

  Furthermore, in the first invention, “stirring under a specific stirring condition” means that an operation of “applying hair dye discharged in a foam state to hair by swallowing it by hand” is objective uniformity as a criterion. This is replaced with a mechanical stirring operation, and specifically refers to stirring under the following conditions.

  That is, a mixture of each hair dye agent is discharged in a foam form from a non-aerosol foamer container having a predetermined gas-liquid mixing ratio, and 150 ml of the mixture is 200 ml in a cylindrical container having an inner diameter of about 6 cm (for example, Store in a beaker. Next, the stirring blade attached to the rotating shaft of a commercially available emulsion tester ET-3A type manufactured by Nikko Chemicals Co., Ltd. is placed so that its rotational center coincides with the center line of the cylindrical container, and its lower end is cylindrical. Position inside the cylindrical container so as to leave a slight clearance with the bottom of the vessel. The stirring blade is a pair of blades extending from the lower end of the support shaft, which is the center of rotation, in the form of a Chinese character “mountain”. The rotation radius of the stirring wing is slightly smaller (about several mm) than the radius of the cylindrical container, and the vertical width of the pair of wings is a size that reaches the liquid level of the foam accommodated in the cylindrical container.

  With the stirring blades positioned as described above, the bubbles are stirred by rotating the stirring blades at a rotational speed of 150 rpm for 3 minutes in an atmosphere at 25 ° C. The foam specific gravity (Y) immediately after stirring under the stirring conditions is ± 3% in comparison with the average foam specific gravity when the foam discharged from the non-aerosol foamer container is applied to the wig. It is confirmed experimentally that the error is within.

  In the first invention, the foam specific gravity (X) and (Y) are those measured as follows. That is, with the opening of a hemispherical dome-shaped plastic cup having a diameter of 7.7 cm facing upward, a bubble to be measured is inserted into the cup to a slight extent. At that time, care is taken so that bubbles do not bite bubbles (so that air other than the air constituting the bubbles is not involved). Then, the foam protruding from the opening of the cup is scraped off with a ruler or the like, the weight of the cup is measured, and the known weight of the cup itself is subtracted to calculate the weight of the foam. In the same way, measure the weight of the cup filled with water and calculate the weight of the water. And the specific gravity of a bubble is calculated on the basis of the calculated weight of water.

  The above-mentioned method for measuring the specific gravity of bubbles is based on the premise that some or all of the bubbles are not crushed and liquefied with respect to the measurement of the specific gravity of bubbles (Y). If a certain foamy hair dye targeted for measurement shows liquefaction immediately after stirring under the stirring conditions described above, the dyeing is not practical as a problem before measuring the ratio Y / X. Since it is a hair agent, it is not treated as an example of the present invention regardless of whether or not the numerical value of the ratio Y / X in this case falls within the numerical range defined in the first invention.

(Configuration of the second invention)
The structure of the second invention of the present application for solving the above problem is that the hair dye according to the first invention is a non-aerosol foamer in which the gas-liquid mixing ratio is in the range of gas: liquid = 7: 1 to 20: 1. It is a hair dye that is used by being discharged from a container.

(Configuration of the third invention)
The configuration of the third invention of the present application for solving the above-described problem is that the hair dye described in the first invention or the second invention is applied to the hair by discharging it in a foam form from a non-aerosol foamer container. How to use.

  In the third aspect of the present invention, the method of “applying to the hair” the hair dye discharged in the form of foam is usually “applied by swallowing by hand”, but is not limited to such an application method.

(Configuration of the fourth invention)
The configuration of the fourth invention of the present application for solving the above problem includes the hair dye described in the first invention or the second invention and a non-aerosol foamer container for discharging the hair dye in the form of foam. It is a hair dye product composed of

  According to the first invention, based on an objective index that “the ratio Y / X is within the range of 0.75 to 2”, “a bubble having a large specific gravity (finely detailed) using a non-aerosol foamer container In addition, a hair dye that can solve the problem of “the foam specific gravity does not decrease even when an operation such as swallowing is applied during application to the hair” is provided.

  That is, the specific gravity (X) immediately after discharging from a non-aerosol foamer container set to a certain standard gas-liquid mixing ratio, and the operation of “applying to the hair by swallowing the foam immediately after the discharge” When the ratio Y / X to the foam specific gravity (Y) immediately after being subjected to a standard mechanical stirring operation corresponding to is within the range of 0.75 to 2, it is applied to the hair by swallowing by hand. Foam specific gravity (bubble fineness) is hardly reduced or rather increased.

  When the ratio Y / X is less than 0.75, it means that the foam becomes rough when applied to the hair by swallowing the discharged foam by hand, and the dyeing of the hair dye cannot be improved, The lightness of the foam may lead to dripping of the foamy hair dye. When the ratio Y / X is more than 2, the foam is too fine to be spread like a gel or cream, and there is a risk that good operability of the foam cannot be obtained when applying hair.

  The first invention can also be understood as the following invention from a different point of view. That is, a hair dye comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and using a mixture of each agent in a foam form from a non-aerosol foamer container. , “Foam specific gravity (X) immediately after being discharged from a non-aerosol foamer container having a gas-liquid mixture ratio of gas: liquid = 13: 1 and immediately after stirring the foam immediately after the discharge under specific stirring conditions For those corresponding to the indicator that the ratio Y / X with respect to the foam specific gravity (Y) is within the range of 0.75 to 2, “non-aerosol foam” can be used without examining the details of the various components. Solves the new problem of foaming with high specific gravity (fine-grained) using a mer container and the foam specific gravity does not decrease even if an operation such as swallowing is applied to the hair. It can be judged that it is a hair dye that can be Yes. This point has been confirmed by many examples described later.

  Therefore, there is provided a useful hair dye that can be used to solve the above problems, which is selected based on a new, objective, and simple index. Alternatively, a new, objective, and simple index for providing a useful hair dye that can solve the above-described problems is provided.
