Description

The present invention relates to cosmetics for hair bleaching or hair dyeing.

Conventionally, liquid or creamy hair bleaching agents and hair dyes have been widely used, but it is difficult to apply them evenly to hair. In particular, the application of the root part of the hair and the back of the head requires skills such as blocking and infinity mirror, and it takes a lot of time.

Therefore, it has been proposed to simplify the decolorization or hair dyeing operation by discharging the agent in the form of bubbles. For example, a two-agent aerosol type and a one-agent non-aerosol type are known. There is. However, the two-agent aerosol type is prone to uneven decolorization and uneven dyeing, metal pressure-resistant containers are oxidized and corroded by hydrogen peroxide, and the internal pressure of the pressure-resistant container rises excessively due to the decomposition of hydrogen peroxide. In addition, the one-agent non-aerosol type has a problem that it is complicated because it is necessary to leave it for a long time after application or to repeat the treatment because the effect obtained by one treatment is poor. ..

On the other hand, there has been proposed a two-agent hair bleaching agent or a two-agent hair dye that is discharged in the form of bubbles from a non-aerosol type former container (see Patent Document 1). This can be applied evenly to the hair by discharging the mixed solution of the first agent and the second agent in the form of bubbles from the former container, and the bubbles remain firmly, so that the finish does not cause color unevenness, especially newborn. It is useful for eliminating the color difference between the part and the dyed part.

Japanese Unexamined Patent Publication No. 2004-339216

The above-mentioned non-aerosol type two-agent hair bleaching or dyeing cosmetics can dye hair evenly with a simple operation, but for hair damaged by hair coloring treatment, hair bleaching treatment, etc. When applied, the foam tends to disappear when the foam is applied to the hair or when the foam is held on the hair, and it may easily cause liquid dripping. In this case, the hair can be dyed evenly and neatly. There was a problem that it disappeared.

The present invention has good foaming performance (foaming and foaming) even for severely damaged hair while taking advantage of the features of the non-aerosol type two-agent hair bleaching or dyeing cosmetics described in Patent Document 1.

Put 100 g of the mixed solution in a squeeze former container (Daiwa Seikansha, volume 210 mL, mesh roughness (opening): 150 mesh (150 meshes per inch (25.4 mm)), tip 200 mesh). When the remaining amount is 80 g, 20 g of foam is discharged into a 1000 mL graduated cylinder, and the volume of the foam is measured 1 minute after the start of discharge. The gas-liquid mixture ratio (mL / g) can be obtained by dividing the volume (mL) of the discharged bubbles by the mass of 20 g.

〔how to use〕
In order to decolorize or dye hair (particularly hair) using the hair bleaching or dyeing cosmetics of the present invention, it is preferable to comb the hair in advance. As a result, the hair is less likely to be entangled during the re-foaming process described later, so that the mixed solution does not scatter. Further, after combing the hair, it is not necessary to perform the blocking operation generally used in the application of the depigmenting agent or the hair dye composition, and it is preferable not to perform the blocking operation. This facilitates the operation of applying the depigmenting agent or hair dye composition described later to the hair and the operation of whipping again. Further, by this re-foaming operation, the hair bleaching or dyeing cosmetic of the present invention can obtain a more even color uneven finish even when applied to the hair with the hair styling product still attached. Be done. Next, the first agent and the second agent of the hair bleaching or hair dyeing cosmetic of the present invention are mixed in a former container.

From the viewpoint of preventing the agent from splashing and dripping, it is more preferable to apply it to the hair after taking it in the hand (with gloves).

After application, leave it for about 3 to 60 minutes, preferably about 5 to 45 minutes. At this time, it is preferable to re-foam the hair on the hair from the viewpoint of further preventing the liquid from dripping during standing and sufficiently spreading the mixed liquid to the roots of the hair. For re-foaming, gas may be injected, an instrument such as a vibrator or brush may be used, or a finger may be used, but it is more preferable to use a finger.

Here, the time of re-foaming may be after the bubbles have completely disappeared, may be in the middle of the bubbles disappearing, or may be before the applied bubbles change. Alternatively, the foam may be applied to the entire range to which the foam is to be applied, or may be in the middle of application. The bubbling may be performed once continuously, or may be repeated intermittently a plurality of times.

After these operations, the mixture is washed away. Then, after shampooing and rinsing as appropriate, wash with water to dry the hair.
