The technical field

The present invention relates to two-component compositions for dyeing the hair.

The level of technology

Currently widely used liquid or creamy compositions for dyeing the hair, such compositions are difficult to apply evenly on hair. In particular, if consumers themselves cause the composition of the hair dye on your own hair near the roots of the hair or on the back of the head, they need to acquire the skill of "pinning the hair or use two mirrors facing each other ("technique with two mirrors"), or the like, and for uniform application of the composition requires careful work.

Accordingly, to simplify the procedure of hair coloring was asked to produce a composition in the form of foam, and is known, for example, two-component hair dye aerosol type and single-component paint neurotologic type. However, in the case of hair dyes aerosol type has certain problems: for example, uneven discoloration or uneven staining occur, probably due to incompatible ratio of the first component and the second component, when mixed, poorly compressible metal container or similar oxidize and corrode under the action shall eat of hydrogen peroxide, as the internal pressure in the sealed container is excessively increased by the decomposition of hydrogen peroxide. In addition, since the one-component paint neurotologic type does not have or has weak decolorizing ability, at once difficult to achieve a significant change in tone color staining. Therefore, a problem arises, i.e. the process of hair coloring becomes burdensome, because hair dye, you need to leave for the manifestation for a long time, and the procedure should be repeated after application.

On the other hand, it was suggested that a two-component composition for dyeing hair to release the foam from the container aerosoling type (for example, patent documents 1 and 2). When letting a solution of the mixture of the first component and the second component in the form of foam from the foam container, changing the ratio of components of the mixture, there is not yet compared with conventional two-component paints, hair spray, and can be achieved reasonable opportunity bleaching or dyeing hair compared to conventional one-component paints for hair neurotologic type.

[Foaming container]

In the present invention the foaming container is a container NEA is rosolino type and is used for mixing the first component and the second component or mortar mixtures with air and releasing it in the form of foam without the use of propellant. The use of a foaming container can also prevent manufactured from it songs from splashing. In particular, the container neurotologic type can be produced with its lower cost compared to a container of the aerosol type, the rate of release can be easily adjusted, the container can be reused when performing certain processing and products can be treated more safely during distribution because it does not require gas-propellant under high pressure.

As the foaming container, you can use any container as long as he is a container neurotologic type having a device for releasing the foam, such as a known foaming container with a pump or flexible foam container with a device for releasing foam.

Foam container with a pump or flexible foam container are forming foam part, such as a mesh, and preferably have a thin mesh from the point of view that when the solution of the mixture of the first component and the second component cures dryness, causing clogging, solids can be immediately dissolved shock foam at the next release, leading to dissolution of the bridging substance. In this case, the grid preferably has the cell from 50 to 280 mesh, more preferably, from 90 to 250 mesh, and even more preferably from 130 to 220 mesh. Creamy foam can be obtained by using the mesh grid in this range. In addition, preferred examples of materials with such cells include nylon, polyethylene, polypropylene, complex, polyester, Teflon (registered trademark), carbon fiber, stainless steel and so on. Among them, nylon, polyethylene, polypropylene and complex polyester are preferable, and the nylon is even more preferred.

More preferably, placed two mesh from the point of view of economic efficiency, stability, foam and the like. In this case, the cell, through which the original passes the solution, preferably are as large or larger than the cell, through which the solution passes later.

In the foaming container part which is in contact with the contents (i.e. the inner wall of the container, the inner wall of the Issuer foam devices etc) preferably consists of a material that does not corrode under the action of the m alkali or hydrogen peroxide and capable of flowing oxygen, which is formed by decomposition of hydrogen peroxide.

As a form of product used for two-component compositions for dyeing the hair, used in the present invention, containing the first component, second component and foaming container, the first component and the second component can be filled into appropriate containers separately from the blowing of the container, so that both parts will need to move in a foam container and mix before use. Alternatively, one component may be in the foam container, so that another component will need to move in a foam container before use. In this case, the second component is preferably loaded into a foaming container consisting of a container having a permeability to gases to prevent pressure build-up in the container due to oxygen generated by decomposition of hydrogen peroxide, and more preferably loaded into a foaming container, made of a material having a permeability to oxygen (for example, polypropylene or polyethylene). On the other hand, the container that barely missing oxygen must be used for the first component, in order to prevent the oxidation oxidative Kras is the index.

[Method of dyeing hair]

For coloring of hair using a two-component composition for dyeing hair according to the present invention is preferably a solution of a mixture of the first component and the second component is released in the form of foam from the foam container neurotologic type of foam is applied to the hair on the head, then the solution mixture re-foamed on the hair of the head and the foam wash off after about 3-60 minutes and preferably within about 5 to 45 minutes after application.

Two-component composition for dyeing hair is used for hair coloring by mixing the first component and the second component immediately before use. In the present invention the first component and the second component can be mixed with any of the following ways:

1) mixing before it is loaded into the main body foaming container;

2) mixing in the main body of the blowing of the container;

3) mixing by combining together the first component and the second component in the mixing chamber of the expander of the gas-liquid;

4) once the foaming of the first component and the second component separately and then mixing them by combining together before the release of the blowing agent;

5) mixing separately released foam PE the first component and the second component prior to application to the hair on the head; or

6) by mixing the separately produced foam of the first component and the second component directly on the hair of the head.

Among them, from the standpoint of simplifying the structure of the foam container, unlimited compositing the first component and the second component, and mixing a reliable and uniform manner is preferred: 1) conducting mixing before it is loaded into the main glass container, or 2) the mixing is carried out in the main body of the blowing of the container.

Preferably hair comb before applying the extruded foam. In the result, the hair almost caught during re-foaming, so that the composition of the hair dye will not spray. In addition, after brushing the hair of the head, not need fixing, usually by applying the composition to hair dye, and preferably consolidation does not hold. Therefore, the composition of the hair dye is easy to apply on hair or easily re-foams, as described below.

From the viewpoint of uniform dyeing of the hair, preventing the formation of droplets of a liquid and a sufficient effect of hair coloring is preferable that a hat is not worn on the hair of the head, which will cause the composition of the hair dye n is directly before coloring the hair. In addition, from the point of view that the solution mixture is not diluted, it is possible to provide a uniform dyeing of the hair, to prevent leakage of liquid drops and to obtain a sufficient effect by dyeing, it is preferable that the hair on his head were dry. If the hair is washed immediately before staining, they preferably should be dry. Hair drying means that the fluid, mainly water, located on the hair due to shampooing, remove at least to the extent that it is not sprayed in the spontaneous condition. In particular, it is preferable to dry the hair with a towel or hair dryer.

The solution mixture of the first component and the second component is released in the form of foam, is applied to the hair on his head after placing it on the hand or a brush, or released directly to the hair on the head. In this case, if use of the hands, it is preferable to wear gloves. In accordance with the method of colouring according to the present invention because it does not require pinning the hair when applying the composition for dyeing hair, the foam can be applied for a short period of time. Therefore, the application of the foam, you can start anywhere on the head, and is not required to start the application from the neck line, in contrast to conventional liquid or creamy the compositions of the two-part hair dyes. Enough to start causing disturbing in parts, and it is preferable to apply the foam from the line of hair on the head or from the place where the hair is separated by a parting.

It is preferable to produce the foam in volume, approximately equal to the size of a lemon, because it is the correct size for placement on one hand, and its easy to apply on the hair on his head with his arms. In this case, the foam produced one hand to another hand. Then, after the foam, available on the arm, causing the hair on the head, the foam again produce on hand for repeat application to the hair on the head. This set of operations can easily hold for a short period of time.

In addition, the foam can be applied on the hair over the entire head or only on a certain part of the hair.

Then, the applied foam re-foamed on the hair on the head. Foam can re-foam by blowing gas, using a tool, such as a vibrator or brush, or your fingers. However, because the two-component composition for dyeing hair can be carefully distributed on the roots of the hair on the head, more preferably, to use the fingers. The degree of foaming using a vibrator or brush, or your fingers, preferably controlled so that the foam was not sprayed.

In this invention the time popcorn the th foaming can be a point in time after the complete disappearance of the foam, during her disappearance or before changing the applied foam. Alternatively, the time of re-foaming may be a time after the foam has been fully applied to the area that was to be put foam or during the application process. Re-foaming can be conducted continuously or intermittently several times. In this invention, when the vibrator, brush or fingers used for re-foaming, remain in contact with part of the hair on the head, or they are brought in contact for 1 second, then even if they are separated from the hair, it is assumed that re-foaming is continuous. Briefly, it is enough to observe the application site and properly emulsify at least before the appearance of drops of the effluent from the applied foam. Regardless of the properties of the foam, the leakage liquid droplets can be prevented by re-expansion foam, which almost disappears. In addition, through re-expansion, you can change the foam, receiving quality, suitable for the dyeing of hair, regardless of differences in the structure of the foam container or properties of the foam, depending on the composition of a two-component hair dye. In some cases it is possible to prevent the leakage Capel is fluid and you can maintain the quality of the foam, suitable for hair coloring, what can be achieved with a certain structure foaming container or a specific composition of a two-component hair dye. Even in such cases it is preferable to conduct a second foaming at least once, as early as possible after application of the foam. By re-aeration in the early stages can prevent uneven staining in the area for which you are applying. This time is preferably in the interval to 5 minutes after application of the expanded foam to the hair on the head, more preferably within 3 minutes, more preferably within 1 minute.

Below are specific examples of preferred methods in processes such as the release of foam for application to the hair on your head and re-foaming, in accordance with partial coloring and full hair coloring.

[Partial hair dyeing]

1) Release the right amount of foam in one hand, put the foam on the part of the hair of the head and hold one operation re-foaming within 1 second to 10 minutes, preferably from 3 seconds to 3 minutes.

2) Release the right amount of foam in one hand, put the foam n the part of the hair of the head and hold one operation re-foaming within 1 second to 10 minutes, preferably, from 3 seconds to 3 minutes, and repeat the operation from 2 to 30 times. Re-foaming spend just over 2 seconds to 20 minutes, preferably from 5 seconds to 5 minutes.

[Color your hair and scalp completely]

3) Release the right amount of foam in one hand, put the foam on the part of the hair of the head and hold one operation re-foaming within from 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes. Repeat this operation for applying foam to the whole head.

4) Release the right amount of foam in one hand, put the foam on the part of the hair of the head and hold one operation re-foaming within from 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes. Repeat this operation for applying foam to the whole head and then carry out the same operation is repeated expansion within from 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes. Then release the right amount of foam in one hand, in addition put the foam on the part of the hair of the head and hold one operation re-foaming on the entire surface of the head within 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes.

5) Release the right amount of foam in one hand, put the foam on the part of the hair of the head and hold one operation re-foaming within from 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes. Repeat this operation for applying foam to the whole head. After applying to the whole head, hold one operation re-foaming within from 3 seconds to 10 minutes, preferably from 5 seconds to 5 minutes.

6) Release the right amount of foam in one hand, put the foam on the part of the hair of the head and hold one operation re-foaming within from 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes. Repeat this operation for applying foam to the whole head. After applying to the whole head, hold one operation re-foaming on the entire surface of the head within 3 seconds to 10 minutes, preferably from 5 seconds to 3 minutes and repeat this operation from 2 to 30 times. Re-foaming spend just over 6 seconds to 20 minutes, preferably from 10 seconds to 5 minutes.

7) Release the right amount of foam on the brush and put the foam on the part of the hair of the head. Repeat this operation for applying foam to the whole head and spend one operation re-foaming across the head with the same brush within from 3 seconds to 10 minutes, preferably from 5 seconds to 5 minutes.

8) Release the right amount of foam on the brush, put the foam on the part of the hair of the head and hold one operation re-foaming using is receiving the same brush within from 3 seconds to 10 minutes, preferably, from 5 seconds to 3 minutes. Repeat this operation for applying foam to the whole head. After applying to the whole head, hold one operation re-foaming using the same brush or hands within from 3 seconds to 10 minutes, preferably from 5 seconds to 5 minutes.

Area re-foaming may constitute all of the hair on the head or only a certain part. Because the foam can be carefully distributed through re-foaming entirely on the hair on the head, can be prevented incomplete staining, even if the application of the foam was omitted any place that is difficult to control, such as hair on the back of the head. When partial colouring, when re-foaming is carried out only at a certain part of the line painted parts can be fuzzy, and provides a natural end result. In addition, when re-foaming, very easy to visually control part, which was distributed in the foam. Respectively, may be excluded incomplete staining of the part you want to paint.

After completion of the foaming hair washed after the foam remained on them for about 3 to 60 minutes, preferably about 5 to 45 minutes. This is the next invention, the above-mentioned time after application of the foam means all the required time from the end of application of all the foam on the entire head or the desired part for rinsing, and refers to the concept, including the time required for re-foaming in addition to the time when the foam just stays on the hair. Then the hair is washed properly with shampoo or treated with a conditioner, then rinse with water and dried.
