Hair dye, method of use thereof, and hair dye supply

The present invention relates to hair dyes, methods of use thereof, and hair dye articles. More particularly, the present invention relates to a hair dye, a method of using the hair dye to hair, and a hair dye article comprising the hair dye and a non-aerosol foamer container, the hair dye comprising a base a hair dye comprising a first agent of the agent and a second agent containing an oxidizing agent, wherein the mixed solution of the first agent and the second agent is discharged from the non-aerosol foamer container in a foam form, wherein the mixed solution is discharged When the foam is formed, there is no problem in the foam durability of the discharged foam on the hair, and a suitable surface tension as a foamy dosage form is achieved.

Oxide hair dyes and hairs which are formed into a paste form, a gel form, etc., which are composed of a plurality of dosage forms including a first agent containing an alkali agent and a second agent containing an oxidizing agent, are conventionally known. Hair dyes such as decolorizers and hair dye removers. The aforementioned hair dye is applied to a hair for hair dyeing treatment using a comb or a brush or the like. However, since the aforementioned hair dye has a high viscosity, it is possible to effectively prevent the dripping of the liquid during the hair dyeing treatment time, but it is difficult to apply it uniformly to the entire hair. In particular, it is difficult for the user's own head and the like to perform a uniform application operation of the hair dye even with a mirror. In addition, it takes a lot of effort to perform so-called hair zoning and the like.

On the other hand, a hair dye which uses a mixture of the respective agents of the multi-dose hair dye in a foam form has been proposed. These hair dyes can be discharged by hand Foam is applied evenly to the hair as a whole. For example, in the following Patent Documents 1 and 2, a hair dye which is applied to hair using a foam type foamer container and discharged in a foam form is disclosed, and a pump foamer or a squeeze foamer is disclosed in Patent Documents 3 to 5, which will be described later.

However, although the hair dye used in the foam form is known to be uniformly applied to the entire hair as described above, in order to secure the aforementioned advantages, in order to make the formation of the foam from the foamer container good, or to discharge The foam has good foaming properties when foamed by hand on the hair, and is usually blended with a surfactant.

However, for such hair dyes, the problem of skin contamination occurs in a wide range due to the spread of the hair dye on the scalp. This problem manifests itself as staining of the skin in, for example, oxidative hair dyes, such as hair bleaching agents or hair. In the hair dye, it is manifested as damage to the skin.

Therefore, the object of the present invention is to provide a hair dye which has no problem in foam formation when discharged from a non-aerosol foamer container or foaming on the hair after discharge, without skin contamination.

As a solution to the aforementioned problems, the applicant of this patent has focused on adjusting the surface tension in hair dyes. The reason for this is that the above-mentioned adverse conditions are related to the facts described later: the surface tension of the hair dye is lowered by the blending of the surfactant, etc., on the one hand, although the foaming or foaming improvement effect as described above can be obtained, on the other hand, the hair dye is obtained. It will spread easily on the scalp.

Further, the present inventors have repeatedly conducted experimental research on various prototypes of hair dyes, and found that the hair dye for non-aerosol foamer containers satisfies "the first agent and the second agent before discharge". The condition that the surface tension of the mixed liquid is in the range of 30 to 50 mN/m under specific measurement conditions is a method for solving the above problems, and completed the invention of the present application.

(Configuration of First Invention)

The first invention of the present invention for solving the above-mentioned problems is a hair dye comprising a first agent containing an alkali agent and a second agent containing an oxidizing agent, and a water-based hair dye is used. The hair dye used for discharging the mixed liquid from the non-aerosol foamer container in a foam form, wherein the surface tension of the mixed liquid of each agent before discharge is in the range of 30 to 50 mN/m under specific measurement conditions.

In the first invention, the surface tension of the mixed solution of each agent before discharge is measured. "Under specific statutory conditions" means the following.

That is, the surface tension was measured by using the Bubble Pressure Method and the surface tension was calculated from the Young-Laplace equation. The aforementioned measurement methods and calculation formulas are well known. Specifically, the mixture of the respective agents before discharge is used to calculate the surface tension by a bubble pressure method such as SITA pro line t15 manufactured by SITA Co., Ltd. to determine the difference between the internal and external pressures of the bubbles Δp (unit :mN/m ² ). Next, the surface tension σ (unit: mN/m) of the foam was determined based on the Young-Laplace formula shown by the following formula (1).

σ=(△p‧r)/2‧‧‧‧‧(1)

In the above formula (1), "r (unit: m)" is a constant radius of the capillary in which the bubble is generated, and therefore σ is obtained by obtaining Δp. In the measurement, although the dynamic surface tension is directly obtained, in actuality, since the value at the time of equilibrium is achieved by the concentration of the tension, it is roughly calculated as the value of the static surface tension, and is used as a representative of the static surface tension measurement method. The measured values of the wheel method or the hanging method are approximately the same.

(Configuration of Second Invention)

The second invention of the present application for solving the above-mentioned problems is a method of using a hair dye according to the first aspect of the invention, which is a hair dye which is applied to a hair from a non-aerosol foamer container in a foam form.

In the second aspect of the invention, the method of "applying the hair dye which is discharged in a foam form to the hair" is usually a case of "application by hand", but is not limited to such an application method.

(Configuration of Third Invention)

The configuration of the third invention of the present invention for solving the above-mentioned problems includes the hair dye according to the first aspect of the invention, and a hair dye preparation comprising the non-aerosol foamer container for discharging the hair dye in a foam form. .

According to the first aspect of the invention, it is possible to solve the problem of "from a non-aerosol foamer container" based on an objective index of "the surface tension of the mixed liquid of each agent before discharge is in the range of 30 to 50 mN/m under specific measurement conditions". The hair dye at the time of discharge, or the foaming after discharge, has no problem in foaming on the hair, and does not cause skin contamination.

In other words, a water-based hair dye comprising a first agent containing an alkali agent and a second agent containing an oxidizing agent is a foamy form of a mixture of the respective agents from a non-aerosol foamer container. The hair dye to be used is formed or discharged from the non-aerosol foamer container as long as the surface tension of the mixture before discharge is in the range of 30 to 50 mN/m under specific measurement conditions. The foam after the foam is no problem on the hair and does not cause skin contamination.

When the aforementioned surface tension is less than 30 mN/m, the hair dye is discharged in a foam form and applied to the hair, and spreads on the scalp to cause skin contamination in a wide range. On the other hand, when the surface tension exceeds 50 mN/m, foam formation at the time of discharge from the non-aerosol foamer container or foaming of the foam after discharge may become insufficient.

The first invention can also understand the invention described later from different opinions. In other words, a water-based hair dye comprising a first agent containing an alkali agent and a second agent containing an oxidizing agent is a foamy form of a mixture of the respective agents from a non-aerosol foamer container. The hair dye used is such an index that the surface tension of the mixture of the respective agents before discharge is in the range of 30 to 50 mN/m under specific measurement conditions, even if the specific components are not specifically studied, It can also be judged that it is possible to solve the problem of "foaming when discharged from a non-aerosol foamer container, or foaming on the hair after discharge, without causing skin contamination". This point is confirmed by a plurality of embodiments described later.

Therefore, it is possible to provide a useful hair dye which can solve the above problems based on new, objective and simple indicators. Alternatively, it provides a new, objective, and simple index for providing a hair dye that can effectively solve the aforementioned problems.

According to the second invention, it is preferred to provide a method of using the hair dye according to the first aspect of the invention.

According to a third aspect of the invention, there is provided a hair dye article comprising the hair dye according to the first aspect of the invention and a non-aerosol foamer container for discharging the hair dye in a foam form.
