Abstract

The present invention relates to a foil applicator for, especially, selectively highlighting keratin fibers, especially human hair, and to methods for producing targeted highlight effects on the hair.

Description

"Blondierfolien"

The present application relates to a film-like applicator for particularly selective color brightening of keratinic fibers, in particular human hair, as well as the method for producing targeted whitening effects on the human hair with such film applicators.

The change in the external appearance, in particular the change in the hair color of the main hair, represents a constant fashionable need in society. In addition to the coloring of the hair stands in particular the lightening of hair in the special focus of the user. For this reason, lightening agents are widely used, which are used either in the barber area or by the home application. When hair coloring - especially in the hair coloring by the home application - several problems arise. On the one hand, natural color nuances are completely covered, making it difficult to realize multitonal colorations. On the other hand, the selective lightening of individual parts of hair, such as fiber bundles, strands and vertices, is difficult to achieve without suitable aids. Often, however, the use of such suitable aids as applicators or brushes requires much experience and skill.

In order to give the hair a more natural appearance, undyed or dyed hairs are usually partially decolorized by targeted application of oxidizing agents. Selected parts of hair ("highlights") to which the oxidizing agent preparation is applied bleach, resulting in a multitonal hair color The application of the oxidizing agent preparation is carried out with a brush or a brush, the hair to be treated optionally with aluminum foil or a so-called "Strähnchenhaube" are selected.

The problem with this approach is that for the preparation of the actual whitening preparation usually first a bleaching powder is mixed with an oxidizing agent and then strands and films must be wetted. In addition, the need for application mixture is often difficult to estimate, so that subsequently has to be remixed or excess mixture must be discarded.

In the prior art, in particular W01993 / 010687A1 was therefore proposed to use so-called Strähnchenfolien or Strähnchenpapiere to create highlights. These are flexible substrates, which are impregnated with an activator comprising ammonia or ammonium salts, and optionally colorants and foaming agents. The impregnated substrates are before use with a hydrogen peroxide-containing Oxidizer treated to make the actual whitening preparation, and wound for use around the brightening strand.

The mixing on the film has some disadvantages for the user. First, it must be ensured that all films are treated with the same amount of oxidizing agent. On the other hand, after the mixing of the oxidizing agent preparation, the time in which the application can be carried out on the strand is limited. However, different formulation compositions and / or varying periods of use may result in undesirable and inconsistent brightening results. Therefore, there continues to be a need for applicator forms that are easy to apply, especially for inexperienced users, for the selective brightening of hair lots, in particular for producing so-called highlights or highlights.

Finally, the sole use of hydrogen peroxide is often not sufficient to achieve a satisfactory whitening result, especially on dark hair. To improve the Aufhellergebnisses Blondiermitteln are often added so-called bleach booster. Particularly suitable as bleach boosters are peroxo salts, in particular peroxodisulfates. Due to their salt form, however, these substances can only be conditionally absorbed on a substrate or so impregnated a substrate without the solid peroxo salts crumble when folding the film and thus Blondierkraft is lost. There is also the danger that these salts will detach when wrapping the tress with the film and thus lead to significant Blondiermittelgradienten within the wrap.

It is therefore the object of the present application to provide Blondiermittel in an applicator, which are easy to use on the one hand. On the other hand, these bleaching agents should enable uniform and improved whitening results, even on dark hair. The brightening agent should be applied to a flexible substrate so that the agent does not detach when folding, rolling or otherwise deforming the substrate. Finally, should be avoided by this brightening cumbersome, subsequent preparation of missing application mixture or discarding excess mixture.

It has now been found that for the targeted and selective use of lightening agents, a special applicator in film form can be advantageously used if the applicator is a film to which a nonwoven-form carrier material has been applied, into which a peroxodisulfate salt has been incorporated has been.

This form of film applicator differs from the prior art in that a significantly improved lightening performance can be achieved. The applied non-woven carrier material allows the separation-free embedding of the peroxodisulfate salts below Maintaining the flexibility of the film and its structure guarantees a simple penetration of liquid into the substrate and thus the triggering of the bleach booster.

A first subject of the present invention is therefore a film applicator for the selective lightening of keratinic fibers, comprising

 (I) as a first layer, a sheet-shaped substrate (A) and

 (ii) as a second layer, a cosmetic bleaching preparation (B), which is applied to the leaf-shaped substrate (A) and contains at least one solid peroxodisulfate salt,

which is characterized in that the bleaching preparation (B) is embedded in a fleece-shaped carrier material.

The terms "film applicator", "highlight film" and "applicator" are used synonymously below.

The applicator according to the invention comprises a flexible substrate. The flexible substrate may take any shape and be made of any material or blend of materials that is flexible. "Flexible" in the sense of the present invention are substrates that are designed in terms of shape and materials so that they can be deformed by manual force, wherein a reversible deformation is preferred.The flexible substrates according to the invention are sheet-shaped or layered "Layered" in the sense of the present invention means that the spatial extent of the substrate along one spatial direction is significantly smaller than along the other two spatial directions, wherein the smallest spatial extent of the substrate in the present invention as "height" or "thickness" is denoted, while the corresponding extent of the substrate in the space directions orthogonal thereto are referred to as "width" and "length." These spatial directions span the planar dimensions of the layer differently, in the context of the present invention, the smaller spatial extent is referred to as "width", the larger than "length".

In the case of preferred substrates according to the invention, the width to height ratio is 10: 1 to 100,000: 1, preferably 50: 1 to 50,000: 1, and in particular 100: 1 to 1000: 1. Particularly preferred sheet-like substrates according to the invention are characterized in that their height is 1 to 1000 μιη, preferably 2.5 to 500 μιη and in particular 4 to 250 μιη. The length and width of preferred sheet-shaped substrates are preferably in the range between 1 and 50 cm, more preferably between 2 and 40 cm, more preferably between 3 and 35 cm and in particular between 4 and 30 cm. A preferred embodiment of the film applicator according to the invention is characterized in that the sheet-shaped substrate (A) has a thickness of 0.5 μm to 1 mm, preferably from 1 μm to 0.5 mm, more preferably from 1.5 μm to 0.1 mm and in particular from 20 μιη to 0.1 mm.

In view of a stable shaping in the brightening process and taking into account the fact that the sheet-shaped substrate (A) should be stable around a strand of hair without further mechanical aids, the use of aluminum foils is particularly preferred. For this purpose, in particular laminates are suitable in which the individual layers are glued together.

Film applicators preferred according to the invention are characterized in that the sheet-shaped substrate (A) is a film of aluminum.

On the leaf-shaped substrate, a cosmetic Blondierzubereitung (B) is applied, which is embedded in a non-woven carrier material.

According to the invention, a fleece or a so-called "nonwoven" is understood to mean a static fiber accumulation which, depending on the production method, leads to a differently densified substance A nonwoven whose density ensures good water entry and exit is preferred.

As the fiber material of the nonwoven different materials are suitable. For example, natural fibers such as pulp or cotton fibers, synthetic fibers such as polyesters, polyamides, polypropylene or polyethylene, or bicomponent fibers combining natural and synthetic materials such as pulp in combination with polyethylene are suitable.

Since the nonwoven support materials should be as chemically inert as possible under the oxidative, usually strongly alkaline conditions of use of the bleaching, those fibers are particularly suitable which have the appropriate stability. In this case, in particular nonwoven support materials made of polypropylene fibers, furthermore polyethylene, polyesters, viscose and acrylic fibers and polyamide fibers are preferred. Nonwoven support materials made of polypropylene fibers are particularly preferred.

The fiber materials can be produced by different methods, such as the known wet-laid, dry-laid, melt-blown, spun-laid or air-laid technologies. The web formation takes place from the optionally roughened (carded) fibers by compaction with the aid of mechanical needling (needled nonwoven), spunlacing (water-jet densification) or spunbonding (thermal, UV or IR densification, possibly with bonding to certain aqueous dispersions, such as polyacrylates, polyvinyl acetates, polybutadienes, latex and butadiene-styrene copolymers).

Such nonwovens are known, inter alia, from cleaning wipes or tissue wipes, but also from other areas, such as liquid or gas filter technology.

It has been proven to provide the nonwoven support hydrophilic so that the absorption of water during use is improved and accelerated, so that a faster and more complete utilization of peroxodisulfate salts is possible. In the context of this invention, equipment is understood as meaning a chemical and / or physical change of the carrier material which imparts to the latter certain properties of use, in this case improved water absorption. The support materials are preferably equipped with anionic surfactants. At the same time, this equipment is accompanied by better wetting of the hair by the ready-to-use preparation.

With regard to the optionally hydrated Si0 ₂ compounds, the present invention is in principle not limited. Preference is given to silicic acids, their oligomers and polymers and their salts. Preferred salts are the alkaline earth metal salts and alkali metal salts, especially the potassium and sodium salts. The sodium salts are preferred.

A further embodiment of the present invention is therefore a film applicator, which is characterized in that the bleaching preparation (B) additionally contains at least silicic acid, its oligo- or polymers, and / or one of their alkali metal or alkaline earth metal salts.

Usable polymers are nonionic polymers, for example vinylpyrrolidinone / vinyl acrylate copolymers, polyvinylpyrrolidinone or vinylpyrrolidinone / vinyl acetate copolymers, zwitterionic and amphoteric polymers, for example acrylamidopropyltrimethylammonium chloride / acrylate copolymers, anionic polymers such as polyacrylic acids or crosslinked polyacrylic acids, natural or derived from natural thickeners Thickening agents such as agar-agar, guar gum, alginic acid, xanthan gum, gum arabic, karaya gum, locust bean gum, linseed gums, dextrans, cellulose derivatives, starch fractions and derivatives such as amylose, amylopectin and dextrins, or fully synthetic hydrocolloids like polyvinyl alcohol.

It has been found that water-soluble polymers can be used particularly advantageously. Such Blondierzubereitungen be particularly well detached from the carrier material in the wrapped hair strands and can be particularly well distributed between the hair fibers. This leads to a uniform whitening result. Particularly suitable polymers according to the invention are therefore cellulose, cellulose ethers, such as methylcellulose, hydroxypropylcellulose, Carboxymethylcellulose, polyelectrolytes such as alginic acid, xanthan gum, gum arabic, or modified natural thickening agents, such as reaction products of guar gum with chloroacetic acid, with ethylene oxide or with propylene oxide, or polyvinyl alcohol.

In the decolorization of hair, especially with dark starting color, there may be undesirable color shifts. This is because it determines natural hair color by melanins in the cortex of the hair fiber, the ratio of the two pigment classes, Eumelanine with brownish-black tones and Pheomelanine with reddish orange tones, determines the actual hair color. In the Blondierprozess the natural melanin dyes are destroyed by oxidative action and thus achieved a decolorization of the fibers. However, because of the different oxidative destruction rate of the different melanin pigment classes, hair is not uniformly decolorized. In darker fibers with high melanin content usually a certain proportion of dyes remains, which is often reflected in yellowish to reddish nuances. Therefore, especially when bleaching darker hair, there is a color shift towards warm tones.

Usually, such color shifts toward warm tones are undesirable to the user. Therefore, this color shift is usually counteracted by a tint with the corresponding complementary color according to the theory of colors. The aim is a silvery-cool impression of the bleaching result. The expert speaks in this context of a matting. Depending on the original hair color, an adapted toning agent mixture must be used to compensate for redder color shifts due to greenish toners or yellowish color shifts through more violet toners.

Suitable toning agents are in particular direct dyes, in particular those which are sufficiently stable under the oxidative and strongly alkaline conditions of a bleaching.

In a further embodiment, therefore, the bleaching preparation (B) additionally contains a combination of at least one blue direct dye and one red direct dye, wherein the weight ratio between the sum of all blue direct dyes and the sum of all red direct dyes is greater than or equal to 1 has. This makes it possible to avoid unwanted color shifts in the direction of pink / rose nuances.

Preferred agents are therefore characterized by the weight ratio between the sum of all blue direct dyes and the sum of all red direct dyes. colorant has a value of 1 to 100, preferably from 1, 5 to 10 and particularly preferably from 2 to 4.

In principle, there are no limits to the choice of substantive dyes. Direct dyes are usually subdivided into anionic, cationic and nonionic substantive dyes. Substantive dyes which can be used according to the invention are nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones or indophenols, if these substantive dyes have a sufficient stability to the harsh conditions of the bleaching process.

For the purposes of the present invention, the pH values are pH values which were measured at a temperature of 22 ° C. In order to adjust the pH, those skilled in the art are familiar with common acidifying and alkalizing agents. The alkalizing agents which can be used for adjusting the pH are typically selected from inorganic salts, in particular the alkali metals and alkaline earth metals, organic alkalizing agents, in particular amines, basic amino acids and alkanolamines, and ammonia. Acidifying agents which are preferred according to the invention are pleasure acids, such as, for example, citric acid, acetic acid, malic acid or tartaric acid, and also dilute mineral acids.

However, it has been found in the context of the investigations on the present invention that preferred bleaching preparations (B) according to the invention are characterized in that they additionally contain an inorganic, solid alkalizing agent. This alkalizing agent, when in contact with water on the hair tress, at least partially dissolves, thus setting the alkaline pH required for bleaching operations. The inorganic alkalizing agent of the present invention is preferably selected from the group consisting of sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, sodium silicate, potassium silicate, sodium carbonate and potassium carbonate. The compositions according to the invention preferably contain the alkalizing agents in amounts of from 0.2 to 25% by weight, in particular from 0.5 to 10% by weight.

For this purpose, the bleaching preparation of the film applicator according to the invention is mixed with an aqueous oxidizing agent preparation (OX) either immediately before separating the hair strand to be lightened or after separation together with the hair strand to be lightened. This is done either by spraying by means of conventional spray bottles or by brushing with the help of a brush or brush. Due to the penetration of water into the water-permeable carrier material of the second applicator layer, the bleaching preparation (B) is dissolved and forms the ready-to-use lightening agent together with the oxidizing agent preparation (OX). Subsequently, the strand to be treated is wrapped in the applicator film, wherein the outside of the wrapping is completely formed by the sheet-shaped substrate, so that adjacent hair parts do not come into contact with the Blondierzubereitung. After the desired exposure time, the film applicator is removed and the treated hair area rinsed thoroughly.

The oxidizing agent preparation (OX) contains in a cosmetic carrier as the oxidizing agent at least hydrogen peroxide. Hydrogen peroxide is preferred even as an aqueous solution used. Hydrogen peroxide can also be used in the form of a solid addition compound of hydrogen peroxide to inorganic or organic compounds such as sodium percarbamide, polyvinylpyrrolidinone n H ₂ 0 ₂ (n is a positive integer greater than 0), urea peroxide and melamine peroxide.

The choice of these other substances will be made by those skilled in the art according to the desired properties of the agents. Regarding further optional components as well as the quantities used these components are expressly based on the specialist manuals known to those skilled in the art, eg. B. Kh.

In addition to the ability to apply hydrogen peroxide on the oxidizer preparation (OX) on the film applicator and so with the Blondierzubereitung (B) provide the ready lightening agent, there is also the possibility of hydrogen peroxide in solid form already present on the film applicator and by contacting with water or a aqueous preparation to generate the ready-brightening agent. Hydrogen peroxide in solid form is to be understood according to the invention addition products of hydrogen peroxide to solid compounds.

Hydrogen peroxide can form adducts with many inorganic and organic compounds. These include addition products of urea (urea-hydrogen peroxide addition compound, UHP, hydroperite, perhydrolurea, hydrogen peroxide-carbamide, percarbamide), melamine (melamine peroxide) and polyvinylpyrrolidinone (PVP-n H ₂ 0 ₂ ) and percarbonates, especially sodium percarbonate and Magnesium percarbonate, and perborates, especially sodium perborate.

In the course of investigations on the present invention, it has been found that it is expedient for reasons of stability to initially spatially separate the bleaching preparation (B) from the hydrogen peroxide addition products, since even small traces of moisture can lead to instabilities and undesired decompositions. Therefore, it is advantageous according to the invention to cover the film applicator with a further layer which comprises a solid oxidizing agent preparation (OX1). For separation from the bleaching preparation (B), it is particularly advantageous if between the oxidizing agent preparation (0X1) and the bleaching preparation (B) an additional separating layer is incorporated, which enables a spatial separation of the two preparations and thus the direct contact of the solid preparations with each other prevented. On the other hand, it is necessary for the release layer to be permeable to water so that the ready-to-use lightening agent is formed after the addition of water or a water-containing preparation of bleaching preparation (B) and solid oxidizing agent preparation (0X1).

A further embodiment of the present application is therefore a film applicator of the first subject of the invention in the form of a multilayer applicator, which is characterized in that the applicator additionally

 (iii) a water-permeable barrier layer applied to layer (ii) and

(iv) a solid oxidizing agent formulation (0X1) applied to the barrier layer (iii), containing as oxidizing agent at least one solid addition product of hydrogen peroxide to organic or inorganic compounds. The solid oxidizing agent preparation (OX1) of layer (iv) contains at least one solid addition product of hydrogen peroxide to organic or inorganic compounds. Hydrogen peroxide can form adducts with many inorganic and organic compounds. These include addition products of urea (urea-hydrogen peroxide addition compound, UHP, hydroperite, perhydrolurea, hydrogen peroxide-carbamide, percarbamide), melamine (melamine peroxide) and polyvinylpyrrolidinone (PVP-n H ₂ 0 ₂ ) and percarbonates, in particular sodium percarbonate and magnesium percarbonate, and perborates, especially sodium perborate.

In a preferred embodiment, the oxidizing agent preparation (OX1) contains a solid addition product of hydrogen peroxide to organic or inorganic compounds, which is selected from addition products of urea, melamine and polyvinylpyrrolidinone.

The oxidizing agent preparation (OX1) contains the solid addition product of hydrogen peroxide to organic or inorganic compounds in an amount of from 0.1 to 60% by weight, preferably from 1 to 50% by weight and more preferably from 2 to 30% by weight , each calculated as 100% H ₂ 0 ₂ and based on the total weight of the solid oxidant preparation (OX1).

In one embodiment of the present invention, the solid oxidizer preparation (OX1) is also embedded in a nonwoven carrier material. In principle, the same fleece-shaped carrier materials may be used as the nonwoven carrier materials of the second layer (ii) described above. Also preferred are carrier materials which are inert to the oxidative environment of the ready-to-use whitening preparation. Fleece-shaped carrier materials made of polypropylene are particularly preferred.

Likewise, the support materials are preferably hydrophilic equipped to promote penetration and storage of water in this layer (iv). This accelerates the dissolution of the solid oxidizing agent, facilitates mixing and thus shortens the contact time and improves the wetting of the hair to be treated.

The solid oxidizing agent preparation (OX1) may contain, in addition to the oxidizing agent itself, further, preferably solid, ingredients. Such other active substances, auxiliaries and additives which can be used according to the invention are the substances described above, such as, for example, other surface-active compounds, complexing agents, anionic, cationic or nonionic, natural or synthetic thickeners, structural and consistency agents, care substances such as protein hydrolysates, care oils; other fats and waxes; Swelling and penetrating substances; Opacifiers and pearlescing agents.

The layer (iv) comprising the oxidizing agent preparation (0X1) preferably has the same dimensions in terms of length and width as the layer (ii). In order to match the proportions of the respective preparation to one another, it is preferable to achieve this tuning by means of different layer thicknesses.

An embodiment of the present invention is characterized in that the solid oxidizing agent preparation (0X1) of the layer (iv) has a layer thickness of from 5 μm to 200 μm, preferably from 10 μm to 150 μm, particularly preferably from 15 μm to 120 μm and in particular from 20 μιη has up to 100 μιη.

For separating blonding preparation (B) and solid oxidizing agent preparation (OX1), the film applicator advantageously contains a separating or blocking layer (iii). This barrier layer is sandwiched between layers (ii) and (iv). It has at least the areal extent of the layer (ii).

Preferably, the layers (ii), (iii) and (iv) each have the same length and width and are superimposed without lateral overlap.

The separating layer (iii) is permeable to water so that, on wetting the layer (iv) and triggering the bleaching preparation, penetration of water into the bleaching preparation of the layer (ii) is made possible. At the same time, the release layer should prevent premature reaction between the constituents of layers (ii) and (iv) by direct contact, especially in the presence of atmospheric moisture.

For this purpose, the release layer may have a lattice-like or fabric-like structure or even a fleece-like structure, which each have suitable pores or openings, which allow the passage of water and aqueous preparations. The water permeability can be influenced by the weave, the thread density and / or the weight per unit area. Suitable materials of the release layer include cellulose, viscose, pulp, polyethylene, polyethylene terephthalate, polypropylene, polyester, polylactate and mixtures thereof. Preferred materials of such a release layer (iii) are polypropylene.

A further embodiment of a water-permeable separating layer (iii) consists in producing the separating layer (iii) from a water-soluble compound. In particular, polymers which are swellable, abradable and / or soluble in water are suitable for this purpose. The term "soluble in water" is understood to mean complete hydration and solution arises. The term "swellable in water" means that on contact with water, water molecules penetrate into the layer, which lead to changes in volume and shape and possibly form a gel Contact with water breaks down. This results in smaller fragments that can be further removed or washed away with water. However, complete solubility in water is not necessary for abradability. The release layer (iii) is preferably present in this embodiment as a film. Preferred materials of the release layer (iii) are cellulose, inulins, cellulose derivatives, in particular hydroxyalkylcelluloses and carboxyalkylcelluloses, as well as polyvinyl alcohols and polyvinyl acetate-polyvinyl alcohol copolymers.

An embodiment of the present invention is characterized in that the water-permeable separating layer (iii) has a layer thickness of 0.1 μm to 100 μm, preferably from 0.5 μm to 50 μm, and in particular from 1 μm to 50 μm.

The release layer (iii) and the oxidizer preparation layer (iv) are intimately bonded to the blonding preparation layer (ii), for example, by bonding and / or welding, preferably by spot welding.

To avoid premature reactions of the exposed layer of the film applicator according to the invention with moisture, in particular atmospheric moisture during storage, it is advantageous to cover this layer with a water-impermeable film.

A further embodiment of the present invention is therefore a film applicator of the first subject of the invention, characterized in that the applicator comprises as additional layer (v) a peelable, water-impermeable film through which the uncovered, air-exposed surface of the bleaching preparation layer (ii) or the oxidizing agent preparation layer (iv) is completely covered.

In a preferred embodiment, the layer (v) as the peelable film has the same areal dimensions as the sheet-shaped substrate of the layer (i). Preferably, the water-impermeable film of layer (v) is bonded to the uncoated edge of the sheet substrate by welding. Here, the welded connection should be designed so that the film of the layer (v) manually without much effort from the layer (i) and without detachment of the other drug layer or layers can be deducted. This can be achieved by the surface properties of the layers and by welding and is known to the person skilled in the art.

Polyethylene, polypropylene and polyethylene terephthalate and polylactide (polylactic acid) are particularly suitable as water-impermeable film materials of layer (v). Preferably, the film (v) has a layer thickness of 0.01 [im to 20 [im, preferably from 0.05 [im to 5 [im.

The water-impermeable film is peeled off manually immediately prior to use, thus exposing the reactive bleaching preparation and / or oxidizing agent preparation of the film applicator.

The film applicators according to the invention are used for the selective brightening and bleaching of keratinic fibers.

A further subject of the present invention is therefore a process for lightening keratinic fibers, which is characterized in that a film applicator comprises at least two layers

 (I) as a first layer, a sheet-shaped substrate and

 (ii) as a second layer a bleaching preparation (B) applied to the sheet-like substrate and containing at least one solid peroxodisulfate salt

 and embedded in a non-woven carrier material,

treated with an oxidizing agent preparation (OX) containing in a cosmetic carrier at least hydrogen peroxide on the side of the bleaching preparation,

Immediately afterwards at least one bundle of keratinic fibers on the prepared so

Slide applicator applied and wrapped in the film applicator,

is left in the film applicator for an exposure time of 10 to 60 minutes,

then the foil is removed and the bundle of keratinic fibers is rinsed out.

The bundle of keratin-containing fibers to be treated is preferably a bundle or a strand of human hair which has been selected from the remaining main hair and separated. The bundle of keratin-containing fibers to be treated is separated from the remaining fibers before treatment by means of a comb or other suitable means.

Depending on the size of the film applicator, two or more hair bundles can also be wrapped, wrapped or wrapped in a film applicator at the same time. In this case, only certain parts of the hair bundles, such as tips, partial lengths or the entire hair fiber lengths to the approach to the scalp, can be taken.

If the film applicator comprises a protective layer in the form of a peelable, water-impermeable layer (v), it is removed immediately before use. The wrapping, wrapping or packaging of the fiber bundle takes place in such a way that the leaf-shaped substrate (A) the layer (i) forms the outside of the package, while the bleaching preparation (B) of the layer (ii) can come into contact with the selected fiber bundle.

The treatment with the oxidation preparation (OX) takes place immediately before the packaging of the fiber bundle in the applicator. For this purpose, depending on the viscosity, the oxidizing agent preparation can be applied with a brush, with a spray bottle or by means of a spray bottle in the form of an aerosol or fine mist before impacting directly onto the film applicator or onto the selected fiber bundle, which has been underlaid with the film applicator not yet wrapped.

Depending on the needs and wishes of the user, individual or several different strands can be wrapped around the entire hair. As a result, punctual, accumulated or evenly distributed reflexes and highlights on the hair can be generated. Preferably, to achieve uniform brightening results, several strands of the main hair are smeared in film applicators according to the invention.

The exposure time is 10 to 60 minutes, preferably 30 to 45 minutes. The exposure phase can take place at room temperature or at elevated temperatures of 40 to 45 ° C. However, the application temperature is preferably room temperature. Depending on the action time and temperature, different levels of brightening results can be achieved, with higher temperatures and / or longer exposure times leading to a stronger brightening.

After the exposure time, the film applicators are removed, the treated fiber bundles are rinsed with water and optionally treated with commercial shampoos and Contioniermitteln.

With regard to further preferred embodiments of the method according to the invention, what has been said about the film applicators according to the invention applies mutatis mutandis.

In the case of multilayer film applicators which comprise a solid oxidizing agent preparation (OX1) in addition to the bleaching preparation (B), activation with water is already sufficient. A third object of the present invention is therefore a process for whitening keratinic fibers, which is characterized in that a multilayer film applicator comprising

 (I) as a first layer, a sheet-shaped substrate and

 (ii) as a second layer, a bleaching preparation applied to the sheet-like substrate, which contains at least one solid peroxodisulfate salt, and is embedded in a fleece-shaped carrier material,

(iii) a water-permeable barrier layer applied to layer (ii) and (iv) treating a solid oxidizing agent preparation (0X1) applied to the barrier layer (iii), containing as oxidizing agent at least one solid addition product of hydrogen peroxide to organic or inorganic compounds, with water on the side of the oxidizing agent preparation (0X1),

Immediately thereafter, at least one bundle of keratinic fibers is placed on the foil applicator prepared in this way and wrapped in the foil applicator,

is left in the film applicator for an exposure time of 10 to 60 minutes,

then the foil is removed and the bundle of keratinic fibers is rinsed out.

For use, the bleaching preparation and the oxidizing agent preparation are moistened with water on the film immediately prior to use.

In an alternative embodiment, one or more of the bleach applicator and oxidizer formulation of the present invention may be wrapped around a wet bundle of keratinic fibers, such as a wet strand of human hair. It may be irrelevant whether the strand of hair was separated from the wet hair and is still sufficiently moistened, or whether the strand of hair was isolated from the dry hair and moistened immediately before wrapping in the film applicator. For lightening especially longer hair, however, it is useful to isolate a bundle of keratinous fibers or a strand from the still dry hair, to moisten this bundle or strand well, and to wrap this moistened bundle in the film applicator according to the invention for lightening. For moistening the tress is especially a spray bottle.

With regard to further preferred embodiments of the method according to the invention of the third subject matter of the invention, mutatis mutandis, the statements made with respect to the preceding subjects of the invention apply.

The use of these film applicators in combination or timely sequence with other color and shape-changing agents, such as oxidative brighteners and / or colorants, is also possible and can be used by the skilled person or user according to his needs and wishes accordingly. In particular, evenly dyed hair or a naturally very homogeneous hair color natural, loosening color reflections and highlights can be achieved in this way. On the other hand, with strong lightening so sharp contrasts and accents within the hairstyle are possible.
