Abstract

The present application is an application device (1) for applying an application liquid on keratin fibers with at least one container (2) for receiving the application liquid, with an application head (3) which is connected to the at least one container (2) and a porous Application body (31) for applying the application liquid by sweeping the fibers, wherein the application liquid contains at least one oxidation dye precursor and is mixed immediately before use with an oxidizing agent.

Description

The The present invention relates to a special application device for applying an application liquid to keratinic Fibers, in particular a liquid Färbepräparats, based on oxidation dye precursors.

Human Hair as an example of a keratin fiber is used today in many ways treated with hair cosmetic preparations. These include about Cleaning hair with shampoos, care and regeneration with rinses and cures, as well as bleaching, dyeing and deforming the hair with colorants, Tints, Wells and styling preparations. There are funds for change or nuancing the color of the head hair a prominent role.

For temporary dyeings become common dyeing or tinting agent used as dyeing Component so-called substantive dyes included. in this connection These are dye molecules that are directly on the hair raise and no oxidative process to form the color need. Belongs to these dyes for example, that from ancient times to the coloring of body and hairs known henna. These dyes are usually against Shampooing vulnerable, so that sometimes after a few washes an undesirable nuances shift or even a visible "discoloration" occurs.

For lasting, intense colors with corresponding fastness properties become so-called oxidation colorants used. Such colorants usually contain Oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidants or of atmospheric oxygen with one another or under coupling with one or more coupler components the actual Dyes off. The oxidation colorants are characterized by excellent, long-lasting staining results out. For Naturally acting dyeings usually has one Mixture of a larger number be used by oxidation dye precursors; in many make continue to use direct dyes for shading.

Finally has in younger Time another dyeing process size Attention found. In this process, precursors of the natural Hair dye melanin applied to the hair; these form then in the context of oxidative processes in the hair natural analog dyes. Such a process with 5,6-dihydroxyindoline as dye precursor has been described in EP-B1-530 229. In, in particular multiple, Application of agents with 5,6-dihydroxyindoline makes it possible for humans with gray hair the natural Reproduce hair color. The coloration can be done with atmospheric oxygen as the only oxidizing agent, so no further Oxidizing agent used must become. In persons with originally medium blonde to brown Hair, the indoline can be used as the sole dye precursor become. For the application in persons with originally red and in particular Dark to black hair color, on the other hand, can be satisfying Results frequently only by the concomitant use of other dye components, in particular special oxidation dye precursors can be achieved.

Usually become the colorants of the three categories described in the form of creams, gels or Solutions usually applied to the fibers using a brush. Further are also dyes on available on the market, as a shampoo preparation or conditioner formulation on the Fibers are applied.

Next These more conventional methods of application have been particularly for temporary colorants based on direct dyes and partly also for colorants based on oxidation dye precursors in the past also developed application devices, with the help of the Means on the keratinic fibers or on special areas the fibers can be applied. The application devices known from the prior art for oxidative dye However, they have the disadvantage that they are very elaborately constructed, since the Preparation containing the dye precursors, from the oxidizing agent preparation be prepared separately until immediately before application got to. Furthermore, the previously known application devices in terms of uniformity paint application and ease of use by the consumer not completely convincing. An important aspect of the ease of use is the "cleanliness the application, i. that neither in the mixing of the colorant components even with the actual dyeing process the environment of the user is contaminated.

Specifically, that describes DE 199 22 092 A1 For example, a cap-like application device for dyeing strands of hair, which is placed on an associated container with hair dye. This application device comprises a plurality of outlet openings for applying the hair dye and be This is followed by guide tines, which are pulled through the hair during use with combing movements. In addition, bristles are arranged around the outlet opening in order to achieve a more uniform application of the hair dye. Nevertheless, the outlet openings with the bristles do not allow a sufficiently metered application of the hair dye. In particular, an excessive leakage of the hair dye and thus also an unwanted wetting of the scalp can not be effectively excluded.

task The present invention was therefore to develop a dyeing system that it allows dyeing Based on oxidation dye precursors until application to pack separately and yet easy to handle made possible by the consumer. About that In addition, also the dyeing Convince properties of the application device.

To extensive research has now surprisingly been found that a special application device with a special oxidative colorant overcomes the disadvantages of the prior art. With the aid of the application device according to the invention is it now possible gray areas of hair, especially on the temples, the contours and the vertex targeted and without big To dye effort ("clean" application).

One The first object of the present invention is therefore an application device for applying an application liquid to keratinic Fibers, in particular hair, with at least one container for Recording the application liquid, with an application head connected to the at least one container is and a porous one order body has for applying the application liquid by sweeping the fibers, wherein the application liquid is the application liquid contains at least one oxidation dye precursor and immediately mixed with an oxidizing agent preparation before use becomes.

One the first parameter essential to the invention is the use at least an oxidation dye precursor in the application liquid. Under the term oxidation dye precursor according to the invention and Kupperkomponenten summarized. In general, the included Application fluids according to the invention at least one developer component and at least one coupler component. It has accordingly proved to be preferred when the application liquid contains at least one developer component.

When Developer components are usually primary aromatic amines with another, in para or ortho position free or substituted hydroxy or amino group, Diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and its derivatives used.

For the purposes of the present invention, aqueous-alcoholic solutions are to be understood as meaning aqueous solutions containing from 3 to 70% by weight of a C ₁ -C ₄ -alcohol, in particular ethanol or isopropanol. The compositions according to the invention may additionally contain further organic solvents, for example methoxybutanol, benzyl alcohol, ethyl diglycol or 1,2-propylene glycol. Preference is given to all water-soluble organic solvents.

In a preferred embodiment the oxidizing agent preparation is formulated as a powder or as a tablet. The term tablets also includes pressed powders according to the invention understand. In the context of this embodiment Percarbamide, percarbonate and perborate are particularly preferred Oxidant.

In the case, that the oxidizing agent preparation is formulated as a tablet is, it has proved to be particularly preferred if they continue at least one dissolution accelerator contains. The term dissolution accelerator includes gas-evolving components, preformed and trapped gases, Disintegrants and their mixtures.

In one embodiment of the present invention, gas-evolving components are used as the dissolution accelerator. Upon contact with water, these components react with each other to form gases in-situ, which create a pressure in the tablet that disintegrates the tablet into smaller particles. An example of such a system are specific combinations of suitable acids with bases. Preference is given to mono-, di- or trihydric acids having a pK _a value of 1.0 to 6.9. Preferred acids are citric, malic, maleic, malonic, itaconic, tartaric, oxalic, glutaric, glutamic, lactic, fumaric, glycolic and mixtures thereof. Particularly preferred is citric acid. It may be very particularly preferable to use the citric acid in particulate form, the particles having a diameter below 1000 μm, in particular smaller than 700 μm, very particularly preferably smaller than 400 μm. Further alternative suitable acids are the homopolymers or copolymers of acrylic acid, maleic acid, methacrylic acid or itaconic acid having a molecular weight of 2,000 to 200,000. Particularly preferred are homopolymers of acrylic acid and copolymers of acrylic acid and maleic acid.

Sodium or potassium salts of the above bases are particularly preferred. These gas-evolving components are preferably contained in the tablets according to the invention in an amount of at least 10% by weight, in particular of at least 20% by weight.

In a further embodiment of the present invention, the gas is preformed or trapped so that upon onset of dissolution of the molded article, gas evolution begins and further dissolution is accelerated. Examples of suitable gases are air, carbon dioxide, N ₂ O, oxygen and / or other non-toxic, non-combustible gases.

In a third, particularly preferred embodiment of the present invention Invention are used as a dissolution accelerator Disintegration aids, so-called shaped body disintegrating agents, incorporated into the moldings, to shorten the disintegration times. Under mold explosives or decay accelerators are according to Römpp (9th edition, Bd. 6, p. 4440) and Voigt "textbook pharmaceutical technology "(6. Edition, 1987, pp. 182-184) Understood excipients for the rapid disintegration of moldings in water or gastric juice and for ensure the release of the pharmaceuticals in a resorbable form.

These Substances that are also referred to as "explosives" due to their effect increase when water enters their volume (swelling). Swelling disintegration aids are for example, synthetic polymers such as polyvinylpyrrolidone (PVP) or natural Polymers or modified natural substances such as cellulose and starch and their derivatives, alginates or casein derivatives.

Disintegrating agents based on cellulose are used as preferred disintegrants in the context of the present invention, so that preferred tablets comprise such cellulose-based disintegrants in amounts of from 0.5 to 50% by weight, preferably from 3 to 30% by weight, based on the total tablet contain. Pure cellulose has the formal gross composition (C ₆ H ₁₀ O ₅ ) _n and is formally a β-1,4-polyacetal of cellobiose, which in turn is composed of two molecules of glucose. Suitable celluloses consist of about 500 to 5000 glucose units and therefore have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrating agents which can be used in the context of the present invention are also cellulose derivatives obtainable by polymer-analogous reactions of cellulose. Such chemically modified celluloses include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. Celluloses in which the hydroxy groups have been replaced by functional groups which are not bonded via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali metal celluloses, carboxymethylcellulose (CMC), cellulose esters and ethers, and aminocelluloses. The cellulose derivatives mentioned are preferably not used as the sole cellulosic disintegrating agent but are used in admixture with cellulose. The content of these mixtures of cellulose derivatives is preferably below 50% by weight, particularly preferably below 20% by weight, based on the cellulose-based disintegrating agent. It is particularly preferred to use cellulose-based disintegrating agent which is free of cellulose derivatives.

The cellulose used as a disintegration aid is preferably not used in finely divided form, but converted into a coarser form, for example granulated or compacted, before it is added to the premixes to be tabletted. The particle sizes of such disintegrating agents are usually above 200 .mu.m, preferably at least 90 wt .-% between 300 and 1600 .mu.m and in particular at least 90 wt .-% between 400 and 1200 microns. The disintegration auxiliaries according to the invention are available commercially for example under the name of Arbocel ^® from Rettenmaier. A preferred disintegration assistants, for example, Arbocel ^® TF-30-HG.

As a further disintegrating agent based on cellulose or as a component of this component, microcrystalline cellulose can be used. This microcrystalline cellulose is obtained by partial hydrolysis of celluloses under conditions which attack and completely dissolve only the amorphous regions (about 30% of the total cellulose mass) of the celluloses, leaving the crystalline regions (about 70%) intact. Subsequent deaggregation of the microfine celluloses produced by the hydrolysis yields the microcrystalline celluloses which have primary particle sizes of about 5 μm and can be compacted, for example, into granules having an average particle size of 200 μm. Suitable microcrystalline cellulose is available commercially for example under the trade name Avicel ^®.

The accelerated resolution the molded body can also be achieved by Pre-granulation of the other components of the tablet achieved become.

One third essential aspect of the present invention is the nature the application device.

A advantageous design of the actual application device provides that the porous order body having continuous pores to achieve capillary action. The capillary properties of the application body, with the application liquid wickedly connected, ensure a reliable transport the application fluid from the container and a metered application of the application liquid by coating on the fibers. According to one further developed variant of the application device, the order body preferably a fibrous, sponge, foam, felt or sintered material type Material structure on. This material structure causes the desired capillary action of the order body, so that, for example, an unwanted leakage or drops of the application liquid from the application body omitted.

alternative to a substantially block-shaped Design of the porous applicator body This can also be several pin-shaped projections exhibit. This enlarges the effective surface of the order body and thus improves the application of the application liquid. Consequently, by means of the swipe movement of the application body over the keratinic fibers, especially the hair, quantitatively as well qualitatively a better coloring result guaranteed.

Another useful embodiment of the application device is achieved in that the application head has a plurality of possibly detachably arranged, comb teeth. These comb teeth are in particular arranged adjacent to the application body. The brushing motion of the entire application head during the application initially provides, by means of the comb teeth, for a disentanglement of the fibers or the hair and thus, above all, for a uniform application of the application liquid. Basically, the detachable arrangement of the comb teeth on the application head allows a more versatile use of the application device. It also proves to be advantageous for such an arrangement when the comb teeth protrude from the porous applicator body. A preferred embodiment of the application device is to arrange the comb teeth of the application head in a circle around the application body. Regardless of the respective coating movement direction, the fibers or hair are first unraveled during use in each case before the actual application of the application liquid takes place.

Farther it is essential to the invention that the actual application liquid only immediately before use by mixing the preparation the oxidizing agent with the preparation containing the dye precursors, will be produced.

The resulting application liquid is in the container just prior to use 2 the device according to the invention, which with the application head 3 connected is. For the container 2 a variety of design options is conceivable. For example, this container can be ergonomically adapted in its shape to the application process in order to facilitate the handling of the application device for the user.

The container 2 can be carried out both as a separate application container, in which the finished mixture is filled before the start of the application. Similarly, it is also conceivable that the container 2 serves as a container application as well as before application as a mixing container. Mixing container and application container are identical in this variant and form the container 2 , For both embodiments, a variety of ways will be described below to design such mixing container constructive.

Around a mixture of the preparation of the oxidizing agent with the preparation containing the dye products, there are a variety of ways some of which are listed here by way of example.

So it is possible, the user of one embodiment of the present invention to provide three or more containers in the hand. The first container contains while the oxidizing agent, the second container, the dye composition and the third container serves as a mixing container. Additional additional reservoir are possible. To prepare the mixture is from the two reservoirs desired amount into the mixing container given, this closed and, for example, by shaking the mixing vessel the two components mixed together. The mixing process can be accelerated by the fact that installations in the mixing tank at shake a turbulent flow (high Reynolds numbers) and thus improve the mixing process and accelerate. For the case that one or both components are chunky or granulated It may be advantageous to internals in the mixing tank to provide such that a mechanical action on a destruction of the granules or the component pieces aims. This is for example by projecting into the mixing container Spikes or barb-like ones Elements achieved. Also internals in the form of stirrers achieve a similar Result.

A another embodiment in the context of the present invention, it is one or more of the reservoir one through a liquid soluble Provide material. This soluble reservoir be in the mixing container given and there by the respective solvent, preferably one Component of the mixture to be prepared, dissolved. This embodiment has for the user the advantage of being during the preparation of the overall preparation never in contact with individual items packed in the storage containers Components comes. To the dissolution process additionally To accelerate, it may be advantageous, even here mechanical To use internals, which comminution of the described reservoir and to achieve a concomitant increase in the speed of the dissolution process. advantageously, are such soluble reservoir designed as a foil bag.

A further variant for producing mixtures according to the invention is the provision of at least two separate containers for storing the respective component, wherein at least one of the containers simultaneously acts as a mixing container. For such embodiments, all the above examples of the variant with at least three containers are also within the scope of the present invention conceivable.

Either with two storage containers, one of which additionally as a mixing container serves as well as in the variant with at least three containers (ie a separate mixing container) It may be advantageous to Umfüllhilfen to ensure that when transferring from the storage containers in the mixing tank / combined Stock mixing vessel no single component spilled becomes. Such Umfüllhilfen are for example extended Ausgießrohre, which allow the nesting of reservoir and mixing container and means for fixing the storage container to the mixing container during the Tapping operation. Such fixing means are, for example snap snap-in connections, Screw connections or bayonet locks.

Around the decanting still further, it may be advantageous to provide funds the pressure equalization between the two containers during the Umfüllvorgangs provide. Such means are, for example, within the opening of a reservoir arranged pipes, which can act as a snorkel. Also Disposable valves in the reservoir for pressure equalization are for Such functionalities are conceivable.

Also helpful for the user is when the storage containers are provided with a closure, which only on a trigger command opens. Thus, the user can ensure that the transfer process does not start until reservoir and mixing tanks in the for the mixing process is in the right position. A design option such closures is for example a tear-off film, which by an increased Internal pressure in the reservoir ruptures and thus the transfer process starts. The internal pressure in the reservoir, for example, by Pumping means or be increased by simply squeezing.

Also mechanical destruction such films by mechanical aids, for example Thorns, or by the contained component itself, for example with tablets, is conceivable.

For example It is also conceivable, the reservoir for granules, powder or chunky goods as a blister pack perform and additionally To provide aids that allow these blisters above the opening of the mixing vessel to place. The user of such mixing systems pushes the in the blister contained component simply through the sealing film through into the mixing container.

Next the variants with three and more containers, or two or more containers It is also conceivable to provide only a single container, both as a storage container as well as a mixing container serves. Such containers have to due to the lack of storage stability of the individual components in Mix with a possibility be equipped for separation of the two components during storage. Such a separation can for example by a partition be generated, which forms two separate chambers. The mixture in such a system is created by the destruction of the Partition or by the arrangement of a valve in this partition. At destructible partitions It may be useful to either destroy this destructibility increase to achieve the internal pressure or by mechanical means of outside of the container directly or indirectly. An embodiment of such mixing containers may for example be a reservoir whose destructible partition by attached to the applicator head, projecting into the container, mechanical Means destructible is. The destruction finds in such a case by screwing or placing the Applicator head in the application position instead. Also separate Devices to destroy the partition are self-evident conceivable in the context of the present invention.

Next a destructible one Partition, it may also be advantageous to use a solid partition to provide a one-way valve. Such a one-way valve could, for example by an increase the internal pressure in one of the two chambers open and thus the component from the one chamber into the other chamber. The increase of Internal pressure can be due to the flexible design of the overall container and its squeezing be achieved by the hand of the user. Also additional Pumping means are quite conceivable.

In addition to the design of a mixing device with a single container and different chambers separated by partitions, which serve as a reservoir, it may be advantageous to provide an empty mixing chamber in addition to the storage chambers before the start of the mixing process. In such an embodiment is located between the storage chambers and the mixing chamber, an element for transferring the components from the individual storage chambers in the mixing chamber. Such elements Kings nen, as already described above embodiments, destructible walls, but also one-way valves in the direction of the mixing chamber.

The Devices for mixing the oxidizing agent shown above with the dye component and possible other components are natural only examples and restrict the present application is not. Also are combinations of all Above shown mixing devices in the present Invention conceivable.

Furthermore, it has proven to be particularly preferred if the resulting application liquid is formulated thin liquid. Application fluids which, after mixing with the oxidizing agent preparation, have a viscosity of 0 to 2000 mPas (measured at 22 ° C. in a Brookfield viscometer with spindle 4 and a speed of 4 rpm), have proved to be particularly preferred. A viscosity of 0 to 100 mPas, measured under the conditions mentioned, is particularly preferred according to the invention.

Next the invention essential Oxidation dye precursors may be the application fluid contain additional components that contribute to the coloring.

In a first embodiment the present invention, the application liquid therefore contain at least one natural analog dye precursor. Preferred precursors of naturally-analogous dyes are those indoles and indolines containing at least one hydroxy or amino group, preferably as a substituent on the six-membered ring. These groups can bear further substituents, for. B. in the form of an etherification or Esterification of the hydroxy group or alkylation of the amino group. In a second preferred embodiment, the colorants contain at least one indole and / or indoline derivative.

Examples

1 application device

Further inventive features also arise from the single drawing, which in perspective Representation of a generic application device shows and in more detail below is explained.

In the 1 shown application device 1 is designed to use a liquid hair dye. In principle, such an application device 1 but also generally to Anwen serve any application liquid for keratinic fibers, wherein the application liquid is applied by stroking the fibers. The application device 1 owns a container 2 , which receives the hair dye or the application liquid and stored until use. For this purpose, it may be useful to provide an absorbent storage element in the interior of the container, which is designed, for example, as a fibrous or sponge-shaped, in order to receive the hair dye or the application liquid.

The container 2 has two separate areas inside. In the first, larger area, the application liquid is prepared before the application. In the second, smaller area, the powdery oxidizing agent preparation is formulated before the application. Immediately before the application, the partition wall between the two areas is pierced by an externally actuated mandrel, so that there is a mixing of the two separately assembled components. In this embodiment, the container is used 2 thus the separate packaging, the mixture of the components and also as a storage container during use.

At an open container end is an application head 3 attached by means of which hair dye is applied to hair. The application head 3 essentially comprises a porous applicator body 31 and several comb teeth 33 which in turn is advantageous to at least one comb element 34 are connected in one piece. It shows 1 the application device 1 in ready-to-use operating position, ie with open application head 3 , Outside of the application times becomes the application head 3 covered by a cap, not shown, for example, at a thread 4 on the container 2 is attached. This will be the application head 3 sealed against the environment, so that drying of the liquid hair dye is effectively prevented.

In detail, the order body 31 with the liquid hair dye or the application liquid in conjunction to promote the liquid in the manner of a wick by capillary action from the container and to provide for applying to the hair. For this purpose, the porous coating body 31 a material structure with continuous pores to achieve the corresponding capillary action. The application body 31 consists in particular of a fibrous, sponge, foam, felt or sintered material-like material. The advantage of such a designed application body 31 consists not only in the reliable promotion of the hair dye but also in the high fluid absorption capacity. Namely, the high liquid absorption capability prevents unwanted leakage or dripping of the hair dye from the application device 1 , Geometric is the application body 31 preferably block-shaped (not shown) or with a plurality of pin-shaped projections 32 designed. Especially the version with several pin-shaped projections 32 increases the effective surface of the application body 31 so that when coloring the hair better staining results are achieved.

The also on the application head 3 immediately adjacent to the application body 31 trained comb teeth 33 serve to disentangle the hair during application of the application device 1 , This disentanglement of the hair causes a more even application of color to the hair. In particular, the individual comb teeth 33 to at least one comb element 34 connected in one piece to simplify handling and manufacturing in general. Furthermore, it makes sense the comb teeth 33 or comb elements 34 detachable at the application head 3 to attach, depending on the particular application, an application without comb teeth 33 or comb elements 34 permit. Generally the comb teeth stand 33 in the longitudinal direction of the application device 1 opposite the applicator body 31 especially in hair applications contact of the scalp with the applicator body 31 or to prevent the application liquid.

According to a further embodiment not shown, the comb teeth 33 circular around the application body 31 lying around at the application head 3 arranged. This will hair during application of the application device 1 regardless of the respective brushing direction, first unraveled before the actual application of the hair dye takes place. This gives improved staining results.
