Description

Two-component hair dye composition

(This application is a divisional application of the application 200780100733.0 filed on October 24, 2007 with the title of invention "Method for Dyeing Hair")

technical field

The present invention relates to a method of coloring hair using a two-component hair dye composition. the

Background technique

Conventionally, liquid or cream hair dye compositions have been widely used as hair dye compositions, but it has been difficult to uniformly apply these hair dye compositions to hair. Especially when applying to the roots of their own hair and the back of the head, consumers themselves need to perform skilled skills such as blocking and looking in the mirror, and they need to be careful in order to apply evenly. the

Therefore, a proposed solution is to spit out the hair dye in the form of foam, thereby simplifying the hair dyeing operation. For example, two-component aerosol hair dyes and single-component non-aerosol hair dyes are known. However, the two-dose aerosol type has the following problems: the mixing ratio of the first and second doses is uncertain, uneven decolorization and uneven dyeing are likely to occur, and metal pressure-resistant containers, etc. are oxidized by hydrogen peroxide and corroded , and the decomposition of hydrogen peroxide causes the internal pressure of the pressure vessel to rise excessively. In addition, the one-dose non-aerosol type has the following problems: it is difficult to improve the color tone change obtained by one operation because it has no decolorization ability or weak decolorization ability, and it is necessary to leave it for a long time after application or repeat this operation. Operations tend to become cumbersome. the

On the other hand, it has been proposed to discharge a two-component hair dye composition in a foam form from a non-aerosol type foamer container (see Patent Documents 1 and 2). In this hair dye composition, the mixed solution of the first part and the second part is expelled from the foaming container in the form of foam, so that it is less likely to cause a deviation in the mixing ratio compared with the conventional two-part aerosol-type hair dye composition , and compared with conventional single-dose non-aerosol hair dye compositions, sufficient decolorization power or hair dyeing power can be obtained. the

However, in these double-dose aerosol-type hair dyes and single-dose non-aerosol hair dyes or hair dyes that are foamed out from a double-dose non-aerosol foam container, there are common problems, namely: It is difficult to adjust the foam quality which balances the easiness of discharge from the container and the handleability on the hair. For this problem, for example, Patent Document 3 proposes a composition that maintains an appropriate foam quality and has excellent foam breaking properties when applied to hair. However, careful handling is still required for uniform application, and a new dyeing method is required. method. the

Detailed ways

In order to foam from a non-aerosol type foaming container, it is necessary to reduce the viscosity of the mixed solution. However, depending on the foam properties of the foam, the foam may collapse during application or during standing, whereby the low viscosity causes the mixed liquor applied to the hair to become prone to dripping. the

In addition, although the simplicity of technology such as partitioning and looking in a mirror is not required, on the other hand, if the defoaming is rapid, the visibility of partial non-coating and uneven coating on the hair at the back of the head It will decrease, so there may be concerns about uneven coloring caused by different reasons from liquid or cream hair dyes. the

The present invention relates to a hair coloring method in which a two-component hair dye composition foamed from a non-aerosol foaming container does not drip and does not occur during the period from being applied to the hair to being rinsed Partially uncoated and unevenly applied. the

The inventors of the present invention have achieved this by re-foaming the applied foam on the hair after using the non-aerosol type foaming container and the two-part hair dye composition and applying the two-part hair dye composition discharged in the form of foam to the hair. , thereby finding a hair dyeing method that satisfies the above requirements. the

According to the present invention, since the applied foam is re-foamed on the hair, even for the hard-to-recognize part such as the hair at the back of the head, local failure of the foam of the two-component hair dye composition will not occur even without using a mirror. Applies and spreads unevenly and, even without zoned areas, lathers quickly and reliably throughout the roots of the hair. Moreover, liquid dripping can be prevented no matter how the properties of the foam vary depending on the constitution of the foaming container or the composition of the two-part hair dye composition. the

"Hair Dyeing Procedure"

[Definition]

In the present invention, so-called hair refers to the hair in the state of growing on the head, and its concept does not include hair that can be detached from the head such as wigs or decorative hair locks. In addition, as long as it is hair, human hair or any animal hair may be used, and human hair is preferable. the

In the hair dyeing method of the present invention, a two-component hair dye composition is used. The two-component hair dye composition is composed of a first agent containing an alkali agent and a second agent containing hydrogen peroxide, and the first agent and the second agent are At least one of the two doses contains a surfactant. In the present invention, the concept of the two-component hair dye composition includes both a dye-containing hair dye composition and a dye-free decolorizing agent composition. The so-called hair dyeing method includes a hair bleaching method in its concept. the

[Mix of first and second doses]

The two-part hair dye composition mixes the first part and the second part immediately before use, and then performs the hair dyeing treatment. In the present invention, the mixing of the first agent and the second agent can adopt any one of the following methods:

1) Mix before filling in the body of the foaming container;

2) Mix in the body of the foaming container;

3) In the gas-liquid mixing chamber of the bubbler, the first agent and the second agent are combined and mixed;

4) After the first and second doses have been foamed separately, the two are combined and mixed before being expelled from the bubbler;

5) Make the foam of the first dose and the second dose spit out separately, and mix these spit out foams before applying to the hair;

6) Spit out the foams of the first dose and the second dose respectively, and mix the spewed foams on the hair. the

Among them, from the viewpoint of simplifying the structure of the foaming container, freely designing the composition of the first agent and the second agent, and ensuring uniform mixing, it is preferable to 1) mix before filling the foaming container body, or 2) Mixing takes place in the body of the foaming container. the

[Non-aerosol foaming container] 

In the present invention, the foaming container is a non-aerosol container, which is used to mix the first agent and the second agent or their mixture with air without using a propellant and spit it out in the form of foam. By using the foaming container, the effect of preventing the spouted hair dye from scattering can be obtained. In particular, non-aerosol-type containers can be manufactured at low cost compared with aerosol-type containers, and the discharge speed can be easily adjusted. If the prescribed treatment is carried out, reuse can be realized, and because high-pressure gas propellants are not required, Therefore, it can be operated more safely during the circulation of products. the

As the foaming container, as long as it is a well-known pump foaming container (pump foamer container), squeeze foaming container (squeeze foamer container), etc., and a non-aerosol type container with a foam discharging member, then Any of the above-mentioned containers can then be used. the

The pump foaming container or squeeze foaming container has a foam generating part such as a mesh, and when the mixture of the first agent and the second agent dries and solidifies and the mesh is clogged, it will solidify due to the circulation of the foam when it is spouted next time It is preferable to have a thin net from the viewpoint of eliminating clogging of the mesh by dissolving the substance immediately. In this case, the mesh of the mesh is preferably 50 to 280 mesh, more preferably 90 to 250 mesh, and still more preferably 130 to 220 mesh. By using a mesh having meshes in this range, creamy foam can be generated. In addition, as the material having the mesh, nylon, polyethylene, polypropylene, polyester, Teflon (registered trademark), carbon fiber, and stainless steel are preferably mentioned, and nylon, polyethylene, polypropylene, and polyester are more preferable. Nylon is most preferred. the

In the foaming container used in the present invention, at least one of the above-mentioned nets is disposed, preferably a plurality of nets are disposed, and more preferably two are disposed from the viewpoints of economical efficiency and foam stability. In this case, whether the mesh through which the liquid passes first is thicker than the mesh through which it passes subsequently, it is preferable that the meshes have the same thickness. the

In the foaming container, the part that the content contacts (the inner wall of the container, the inner wall of the foam discharge member, etc.) will not be corroded by alkali and hydrogen peroxide, and this part is preferably permeable to the oxygen generated by the decomposition of hydrogen peroxide. made of materials. the

As the product form of the double-component hair dye composition composed of the first agent, the second agent and the foaming container used in the present invention, it can be: the first agent or the second agent is respectively filled in other than the foaming container. In the container, when in use, move the two doses into the foaming container for mixing, or: fill one of the doses into the foaming container, and fill the other into other containers, and when in use, put the Another dose is transferred to the foaming container. In this case, in order to prevent the pressure in the container from rising due to the oxygen generated by the decomposition of hydrogen peroxide, it is preferable to fill it into a bubbler container composed of a gas-permeable container, and more preferably to a container made of an oxygen-permeable container. Store in blister containers of non-volatile material such as polypropylene or polyethylene. On the other hand, in order to prevent the oxidation of the oxidation dye, it is necessary to use a container that is difficult to permeate oxygen for the first dose. the

[specific procedure]

In the hair coloring method of the present invention, the hair is preferably pre-combed before the expelled foam is applied. Thereby, in the treatment of refoaming the foam, the hair becomes difficult to tangle, so there is no fear of the hair dye composition scattering. In addition, after combing the hair, it is not necessary to carry out the sectioning operation which is generally used when applying the hair dye composition, and it is preferable not to perform the sectioning operation. This facilitates the operation of applying the hair dye composition to the hair and the operation of refoaming the foam, which will be described later. the

From the viewpoint of uniform hair dyeing, prevention of liquid dripping, and sufficient hair dyeing effect, it is preferable not to use a hair styling agent immediately before hair dyeing treatment on the hair to which the hair dye composition is applied. In addition, dry hair is preferable from the viewpoint of uniform hair dyeing without diluting the mixed liquid, preventing liquid dripping, and obtaining sufficient hair dyeing effect. When shampooing the hair immediately before the hair dyeing treatment, it is preferable to dry the hair before the hair dyeing treatment. Drying the hair means that the liquid, mainly water attached by shampooing, is removed at least to the extent that it does not drip in a natural state. Specifically, it is preferably in a towel-dried state or a hair dryer-dried state. the

The mixture of doses 1 and 2 in the form of a foam can be applied to the hair after dipping the hand or the end of a brush, or directly to the hair. Here, when using hands, it is preferable to wear gloves. According to the dyeing method of the present invention, the foam can be applied in a short time since the partition operation generally used in the application of the hair dye composition is not required. Therefore, the hair part where the foam is applied can be applied from any part, and it does not need to be applied from the back of the neck like conventional liquid or cream two-component hair dye compositions. What is necessary is just to start application from the part to pay attention to, and it is preferable to start application from the hairline part of hair or the parting line part of hair. the

If the foam is spit out to the size of a lemon, it is easy to pick it up with one hand, and it is easy to apply it to the hair by hand, so it is preferable. In this case, the foam discharge operation is performed with one hand, and the foam is picked up with the other hand. Then, after once applying the foam taken in the hand to the hair, the foam is spit out again into the hand and applied to the hair, and this operation is repeated. This continuous operation can be performed very easily and in a short time. the

In addition, the scope of applying the foam can be either the whole hair or only a specific part. the

Next, the applied foam is re-lathered on the hair. For re-foaming the foam, gas can be injected, an appliance such as a vibrator or brush can be used, or fingers can be used, but are more preferred because of the need for a two-part hair dye composition to penetrate the hair roots well . The speed of foaming using a vibrator, brush or fingers is preferably controlled to such an extent that the foam does not scatter. the

Here, the time to refoam the foam may be after the foam has completely disappeared, may be in the middle of disappearing the foam, or may be before the applied foam changes. In addition, alternatively, in the range where foam application is required, it may be after complete application, or may be in the middle of application. Foaming the foam again may be performed continuously once, or may be repeated several times intermittently. Here, if the vibrator, brush, or fingers used to re-foam the foam continuously touch a part of the hair continuously, or even if there is time to leave it, if it comes into contact again within 1 second, then the foam will be re-foamed. Bubbles are continuous. Observe the applied site, as long as proper foaming is performed at least from the applied foam until it becomes liquid and drips. Liquid dripping can be prevented regardless of the nature of the foam by re-foaming the foam that is about to disappear. In addition, even if the properties of the foam differ depending on the composition of the foaming container and the composition of the two-component hair dye composition, the foam quality can be changed to a foam quality suitable for hair dyeing by re-foaming the foam. Considering that if the composition of the foaming container and the composition of the two-component hair dye composition are specific, dripping of the liquid can be prevented, and even if it is directly applied, it is easy to maintain the foam quality suitable for hair dyeing, but even in this In some cases, it is also preferred to refoam at least once as early as possible after the foam has been used. By re-foaming the foam at an early stage, it prevents color unevenness where it needs to be applied. The timing is preferably within 5 minutes, more preferably within 3 minutes, and particularly preferably within 1 minute after application of the discharged foam to the hair. the

Specific examples of preferred procedures in the steps from foam discharge to application to the hair and refoaming the foam are exemplified below by dividing them into partial hair dyeing and total hair dyeing. the

[Partial hair coloring]

1) Spit out an appropriate amount of foam onto one hand, and apply the foam to a part of the hair, and re-foam the foam once for 1 second to 10 minutes, preferably 3 seconds to 3 minutes . the

2) Spit out an appropriate amount of foam to one hand, and apply the foam on a part of the hair, and perform 2 to 30 times to make the foam foam again, each time for 1 second to 10 minutes, preferably 3 seconds Clock ~ 3 minutes. The total execution time is 2 seconds to 20 minutes, preferably 5 seconds to 5 minutes. the

[All hair coloring]

3) Spit out an appropriate amount of foam onto one hand, and apply the foam to a part of the hair, and perform 1 time to re-foam the foam for 3 seconds to 10 minutes, preferably 5 seconds to 3 minutes . Repeat this operation until the foam is applied to all hair. the

4) Spit out an appropriate amount of foam onto one hand, and apply the foam to a part of the hair, and perform 1 time to re-foam the foam for 3 seconds to 10 minutes, preferably 5 seconds to 3 minutes . This operation is repeated until the foam is applied to the entire hair, and the foam is re-foamed once for 3 seconds to 10 minutes, preferably 5 seconds to 3 minutes. Then spit out an appropriate amount of foam to one hand, and apply the foam additionally on a part of the hair until it spreads all over the hair, and perform 1 time to make the foam foam again. The time is 3 seconds to 10 minutes, preferably 5 minutes. seconds to 3 minutes. the

5) Spit out an appropriate amount of foam onto one hand, and apply the foam to a part of the hair, and perform 1 time to re-foam the foam for 3 seconds to 10 minutes, preferably 5 seconds to 3 minutes . Repeat this operation until the foam is applied to all hair. After the application to the whole hair is completed, the foam is refoamed once for 3 seconds to 10 minutes, preferably 5 seconds to 5 minutes. the

6) Spit out an appropriate amount of foam onto one hand, and apply the foam to a part of the hair, and perform 1 time to re-foam the foam for 3 seconds to 10 minutes, preferably 5 seconds to 3 minutes . Repeat this operation until the foam is applied to all hair. After finishing the application to the whole hair, perform 2 to 30 times on the whole hair to refoam the foam, each time for 3 seconds to 10 minutes, preferably 5 seconds to 3 minutes. The total execution time is 6 seconds to 20 minutes, preferably 10 seconds to 5 minutes. the

7) Discharge an appropriate amount of foam onto the brush, and apply the foam to a part of the hair. This operation is repeated until the foam is applied to the entire hair, and the foam is re-foamed to the entire hair using the same brush for 3 seconds to 10 minutes, preferably 5 seconds to 5 minutes. the

8) Spit out an appropriate amount of foam onto the brush, and apply the foam to a part of the hair, and use the same brush or hand to re-foam the foam once for 3 seconds to 10 minutes, preferably 5 seconds ~3 minutes. Repeat this operation until the lather is applied to all hair. After the application to the whole hair is completed, use the same brush or hand to refoam the foam once for 3 seconds to 10 minutes, preferably 5 seconds to 5 minutes. the

Refoaming can be performed either on the whole hair or only on specific parts of the hair. If you re-foam the entire hair, even if you forget to apply the foam to the hard-to-recognize part like the hair on the back of the head, the foam will spread and prevent the part from getting uncolored. If you re-foam only a specific part of the hair in partial hair dyeing, you can lighten the dyed border and achieve a natural tone. In addition, if the foam is re-foamed, the part where the foam spreads becomes very easy to see, so it is possible to prevent the part that needs to be dyed from being partially dyed. the

After the application of the foam, it is left to stand for about 3 to 60 minutes, preferably about 5 to 45 minutes, and then rinsed. In the present invention, the time after the above-mentioned foam application refers to the total time required after the foam is completely applied to the entire hair or a desired part of the hair until it is rinsed, and the concept includes the time for simply leaving Also included is the time required to re-foam the foam. Then, wash and dry your hair after using an appropriate shampoo and conditioner. the
