Description

Two-component hair dye

This invention relates to a two-part hair dye.

Previously, as a two-part hair decoloring agent or a hair dye, it has been popular in liquid or cream form. However, evenly applying these to the hair is more difficult for a raw hand. The reason for this is that in order to prevent dripping during placement, the viscosity of the mixture applied to the hair is adjusted to be as high as about 1000 to 10,000 mPa·s, and it is difficult to uniformly spread the agent, and it is difficult to sufficiently spread the agent to the root of the hair. Further, when applied to the root or the back of the hair, it is necessary to be skilled in the techniques of blocking and facing the mirror, and it takes a lot of time.

On the other hand, the industry has proposed that a mixture of a two-part hair bleaching agent or a two-part hair dye is sprayed from a non-aerosol type foam container in a bubble form (Patent Document 1). The hair bleaching agent or the hair dyeing agent sprays a mixture of the first agent and the second agent in a bubble form from a non-aerosol type foaming container, whereby the hair can be simply and uniformly applied to the hair even if it is a hand. And no color unevenness is produced when finished. Since it can be applied simply, there is no need for zoning, mirroring, etc., and the time required to dye the hair is much shorter than before. Because of its superior performance compared to the previous one, it is supported by a wide range of customers regardless of gender and age. Therefore, various products are being developed according to the needs of a large number of customer layers.

Here, in the two-part hair bleaching agent or the two-part hair dye described in Patent Document 1, the viscosity of the mixture is 1 to 300 mPa·s as compared with the previous mixture of the hair dyes. It is low and the mixture must be sprayed from a non-aerosol type foaming vessel in a bubble form. Therefore, it is necessary to improve the storage stability which is easy to be lowered, to ensure the discharge property from the non-aerosol foaming container, and to provide basic performance as a decolorizing agent or a hair dyeing agent. Thus, a decoloring agent or a hair dye of a type in which a mixed liquid is ejected in a bubble form from a non-aerosol type foaming container, and a physical property such as a liquid or paste decoloring agent or a hair dye known in the past. It is completely different, so the formula used in these previous dosage forms cannot be used. For example, there is a case where a large amount of a component such as polyfluorene or a higher alcohol is contained in a liquid or paste form in order to improve the feeling of discoloration or dyeing, but even if such a formulation is simply applied to non-aerosol foaming The container also does not emit good bubbles. Therefore, the formulation of a two-part hair dye using a non-aerosol foaming container must be studied in terms of non-aerosol foaming containers.

Therefore, in the two-part hair bleaching agent or the two-part hair dye of Patent Document 1, a cationic polymer is used for the purpose of improving the feeling of the touch, but in order to provide a product to a wide range of customers, it is necessary to concentrate on various flow paths. Conduct product development. Therefore, in the development of the product of the two-part hair bleaching agent or the two-part hair dye described in Patent Document 1, it is necessary to satisfy the stricter storage stability than before.

First, the gas-liquid mixture ratio was determined by measuring the weight and volume of the bubbles sprayed at 25 °C. Add 100 g of the mixture to the extrusion foaming vessel (Dahe Can Co., Ltd., volume 210 mL, mesh thickness (mesh) for the mixing chamber 150 mesh (150 grids per 1 inch (25.4 mm)), front end 200 In the mesh), 20 g of the bubble was ejected into a cylinder of 1000 mL from the time when the remaining amount was 80 g, and the volume of the bubble was measured 1 minute after the start of the ejection. The gas-liquid mixture ratio (mL/g) was determined by dividing the volume (mL) of the discharged bubble by the weight of 20 g.

[foaming container]

In the present invention, the foaming container is a non-aerosol type container, and is used to mix a mixture of the first agent and the second agent with air and to eject it in a bubble form without using a propellant. By using a foaming container, it is also possible to obtain an effect of preventing scattering of the discharged agent. Among them, the non-aerosol type container can be manufactured at a lower cost than the aerosol type container, and does not require the use of a high pressure gas propellant, so that it can be operated more safely during product circulation.

As the foaming container, a known pump foaming vessel, a squeeze foaming vessel, an electric foamer, a pressure storage pump foaming vessel, or the like having a bubble discharge mechanism can be used. More specifically, for example, foods and containers (vol. 35, No. 10, p588-593 (1994); vol. 35, No. 11, p624-627 (1994); vol. 36, No. 3 , p154~158 (1995)) Pump type E3 type, pump foamer type F2 (above manufactured by Daiwa Can Co., Ltd.), extrusion foamer (manufactured by Daiwa Can Co., Ltd.), electric foaming (manufactured by Matsushita Electric Works Co., Ltd.), jet foamer (Airspray International), etc. The foaming container used as the two-part type hair dye of the present invention is preferably a pump foaming container and a squeeze foaming container in terms of being inexpensive and convenient to use.

The pump foaming container or the extrusion foaming container has a bubble generating portion such as a mesh, and it is preferable to have a thin mesh in the following viewpoint: a mixture of 1 and 2 agents is dried and solidified to cause clogging. In the case, the clogging can be eliminated by immediately dissolving the cured product by the flow of the bubble at the next discharge. At this time, as the mesh of the network, it is better to have 50 to 280 meshes, and then preferably 90 to 250 meshes, and more preferably 130 to 220 meshes. Here, the term "net" refers to the number of meshes per one inch. Milky bubbles can be produced by using a mesh of meshes of this range. Further, as a material of such a mesh, nylon, polyester, or the like can be preferably exemplified.

The foaming container used in the two-component hair dye of the present invention is provided with at least one, preferably a plurality of the above-mentioned nets, especially in terms of economy, stability of foam, etc., preferably 2 pieces are provided.

In the foamed container, the portion in contact with the contents (the inner wall of the container, the inner wall of the bubble ejecting mechanism, etc.) is preferably permeated by oxygen which is not corroded by alkali and hydrogen peroxide and which decomposes hydrogen peroxide. Made up of materials.

As a product form of the two-part hair dye of the present invention comprising the first agent, the second agent, and the foam container, the first agent or the second agent may be separately filled in a container different from the foam container, and In use, the two doses are transferred to a foaming container for mixing; one of the agents may be filled in the foaming container and the other agent may be filled in the other container, and another agent may be transferred to the foaming container during use. Inside. In this case, in order to prevent the pressure generated in the container from rising due to the oxygen generated by the decomposition of hydrogen peroxide, it is preferable to fill the container having gas permeability, and it is preferable to have oxygen. A foamed container formed of a transparent material such as polyethylene. On the other hand, in order to prevent oxidation of the oxidative dye, it is necessary to use a container in which oxygen is hard to permeate.

[Instructions]

When dyeing or decolorizing hair (especially hair) using the two-part hair dye of the present invention, it is preferred to comb the hair in advance. Thereby, the hair is not easily entangled in the process of re-foaming described later, and therefore there is no fear that the mixed liquid will scatter. Further, it is not necessary to carry out the partitioning operation which is common when the hair dye composition is applied after combing the hair, and it is better not to perform the partitioning operation. Thereby, the operation of applying the hair dye composition to the hair or re-foaming described later becomes easy. Then, the first agent of the two-part hair dye of the present invention and the second agent are mixed in a foaming container. The foamy mixture sprayed from the container can be directly applied to the hair, and can also be applied to the hair using a tool such as a hand or a brush. From the viewpoint of preventing scattering or droplets of the agent, it is more preferable to apply it to the hair after being temporarily put into the glove.

After application, it is left for about 3 to 60 minutes, preferably about 5 to 45 minutes. At this time, it is preferable to foam again on the hair from the viewpoint of further preventing the droplets from falling during the placement and allowing the mixture to sufficiently spread to the root of the hair. When foaming again, it is also possible to inject gas, or use a device such as a vibrating machine or a brush, or use a finger, and more preferably use a finger.

Here, the period of re-foaming may be after the bubble completely disappears, or may be in the middle of the disappearance of the bubble, or may be before the change of the applied bubble. Or it can be applied midway through all the ranges in which the bubble is to be applied. The refoaming operation can be performed once in succession or repeatedly in multiples.

The mixture is rinsed after these operations. Thereafter, after appropriate shampooing and hair care, water washing is performed to dry the hair.
