Description

B e s c h r e i b u n g Description
Mittel zur Färbung und Entfernung von FasernFiber dyeing and removing preparations
Gegenstand der vorliegenden Erfindung ist ein Mittel zur Entfärbung von Keratinfasern (insbesondere menschlichen Haaren), ein Verfahren zur Entfärbung von Keratinfasern unter Verwendung dieses Mittels sowie ein Mehrkomponenten-Kit zur nicht-oxidativen Färbung und späteren Entfärbung von Fasern, insbesondere von menschlichen Haaren, der sowohl ein Mittel zur Erzeugung einer nicht-oxidativen Färbung auf der Faser als auch ein Mittel zur Entfärbung der Färbung enthält.The present invention relates to an agent for decolorizing keratin fibers (in particular human hair), a process for decolorizing keratin fibers using this agent and a multi-component kit for non-oxidative coloring and subsequent decolorization of fibers, in particular human hair, which both contains a means for producing a non-oxidative color on the fiber as well as a means for decoloring the color.
Direktziehende Farbstoffe, insbesondere Nitrofarbstoffe, sind in nicht- oxidativen Färbemitteln (sogenannten Tönungsmitteln) weit verbreitet. Sie können aufgrund ihrer geringen Größe in das Haar eindringen und es - zumindestens in den äußeren Bereichen - direkt anfärben. Derartige Tönungen sind sehr haarschonend und überstehen in der Regel mehrere Haarwäschen.Direct dyes, especially nitro dyes, are widely used in non-oxidative dyes (so-called tinting agents). Due to their small size, they can penetrate the hair and dye it directly - at least in the outer areas. Such tints are very gentle on the hair and usually withstand several washes.
Eine teilweise Entfärbung dieser Tönungen ist deshalb durch mehrmaliges Haarewaschen zwar möglich, eine gezielte und vollständige sofortige Entfernung der Haarfarbe ist auf diesem Wege jedoch nicht möglich. Soll eine besondere Haarfarbe nur für einen kurzen Zeitraum getragen werden, ist daher die Entfernung der Haarfarbe unter milden und schonenden Bedingungen ein bisher ungelöstes Problem.A partial decolorization of these tints is therefore possible by washing the hair several times, but targeted and complete immediate removal of the hair color is not possible in this way. If a special hair color is only to be worn for a short period of time, the removal of the hair color under mild and gentle conditions is an unsolved problem.
ERSATZBLÄΓT (REGEL 26) Aus der DE-A-20 24 799 ist zwar bereits ein alkalisches (pH=7,5-11 ,5) Mittel zum Herauslösen von Farbstoffen aus menschlichem Haar bekannt, das aus einem Zweiphasen-Flüssigkeitssystem für den Farbstoff aus Wasser und einem organischen Lösungsmittel besteht. Dieses Mittel hat jedoch den Nachteil, daß es wegen seiner Zweiphasigkeit in der Praxis schwer anwendbar ist, weil sichergestellt werden muß, daß beide Phasen gleichmäßig mit allen Teilen des zu entfärbenden Haares in Berührung kommen. Hieraus ergibt sich, daß dieses Mittel in seiner Entfärbewirkung schwächer und nicht immer zuverlässig ist. Außerdem ist es nicht für alle Haarfarbstoffe, sondern vor allem zum Herauslösen saurer Farbstoffe geeignet.SPARE BLADE (RULE 26) From DE-A-20 24 799, an alkaline (pH = 7.5-11.5) agent for removing dyes from human hair is already known, which consists of a two-phase liquid system for the dye from water and an organic solvent consists. However, this agent has the disadvantage that it is difficult to apply in practice because of its two-phase nature, because it must be ensured that both phases come into contact with all parts of the hair to be decolored evenly. It follows from this that this decolorizing agent is weaker and not always reliable. In addition, it is not suitable for all hair dyes, but especially for removing acid dyes.
Die Entfernung der Haarfarbe unter milden und schonenden Bedingungen ist daher ein bisher ungelöstes Problem. Erfindungsgemäß wird diese Aufgabe durch den Einsatz eines geeigneten sauren Entfärbemittels gelöst.The removal of the hair color under mild and gentle conditions is therefore an as yet unsolved problem. According to the invention, this object is achieved by using a suitable acid decolorizing agent.

Die direktziehenden Farbstoffe werden in dem Färbemittel in einer Gesamtmenge von etwa 0,01 bis 10 Gewichtsprozent, vorzugsweise 0,1 bis 5 Gewichtsprozent, eingesetzt.The substantive dyes are used in the colorant in a total amount of about 0.01 to 10 percent by weight, preferably 0.1 to 5 percent by weight.
Das Färbemittel kann beispielsweise in Form einer Lösung, insbesondere einer wäßrigen oder wäßrig-alkoholischen Lösung vorliegen. Die besonders bevorzugten Zubereitungsformen sind jedoch eine Creme, ein Gel, ein Aerosolschaum oder eine Emulsion. Ihre Zusammensetzung stellt eine Mischung der Farbstoffkomponenten mit den für solche Zubereitungen üblichen Zusätzen dar.The colorant can, for example, be in the form of a solution, in particular an aqueous or aqueous-alcoholic solution. However, the particularly preferred preparation forms are a cream, a gel, an aerosol foam or an emulsion. Your composition represents a mixture of the dye components with the usual additives for such preparations.
Übliche Zusätze in Lösungen, Cremes, Emulsionen, Aerosolschäumen oder Gelen sind zum Beispiel Lösungsmittel wie Wasser, niedere aliphatische Alkohole, beispielsweise Ethanol, n-Propanol und Isopropanol oder Glykole wie Glycerin und 1 ,2-Propandiol, weiterhin Netzmittel oder Emulgatoren aus den Klassen der anionischen, kationischen, amphoteren oder nichtionogenen oberflächenaktiven Substanzen wie Fettalkoholsulfate, oxethylierte Fettalkoholsulfate, Alkylsulfonate, Alkylbenzolsulfonate, Alkyltrimethylammoniumsalze, Alkylbetaine, oxethylierte Fettalkohle, oxethylierte Nonylphenole, Fettsäurealkanolamide, oxethylierte Fettalkohole, oxethylierte Nonylphenole, Fettsäurealkanolamide, oxethylierte Fettsäureester, ferner Verdicker wie höhere Fettalkohole, Stärke oder Cellulosederivate, Parfüme, Haarvorbehandlungsmittel, Konditionierer, Haarquellmittel, Konservierungsstoffe, weiterhin Vaseline, Paraffinöl und Fettsäuren sowie außerdem Pflegestoffe wie kationische Harze, Lanolinderivate, Cholestehn, Pantothensäure und Betain. Die erwähnten Bestandteile werden in den für solche Zwecke üblichen Mengen verwendet, zum Beispiel die Netzmittel und Emulgatoren in Konzentrationen von etwa 0,5 bis 30 Gewichtsprozent (bezogen auf die Farbträgermasse), die Verdicker in einer Menge von etwa 0,1 bis 25 Gewichtsprozent (bezogen auf die Farbträgermasse) und die Pflegestoffe in einer Konzentration von etwa 0,1 bis 5,0 Gewichtsprozent (bezogen auf die Farbträgermasse).Usual additives in solutions, creams, emulsions, aerosol foams or gels are, for example, solvents such as water, lower aliphatic alcohols, for example ethanol, n-propanol and isopropanol or glycols such as glycerol and 1,2-propanediol, and also wetting agents or emulsifiers from the classes of anionic, cationic, amphoteric or non-ionic surface-active substances such as fatty alcohol sulfates, ethoxylated fatty alcohol sulfates, alkyl sulfonates, alkylbenzenesulfonates, alkyltrimethylammonium salts, alkylbetaines, oxyethylated fatty alcohols, oxyethylated nonylphenols, fatty acid alkanolamides, oxethylated fatty alcohols, fatty alcohols, fatty alcohol alcohols, fatty alcohol alcohols, starch fatty acids, fatty alcohol alcohols, oxyethyl fatty alcohol alcohols, starch fatty acids, fatty acid alcohol fatty acids, fatty acid alcohol fatty acids, starch fatty acids, fatty acid alcohol fatty acids, starch fatty alcohol alcohols, oxyethylated fatty alcohol fatty alcohols, fatty acid alcohol fatty acids, starch alcohols, oxyethylated fatty alcohol fatty alcohols, starch alcohols, oxyethylated fatty alcohol fatty alcohols, starch alcohols, oxyethylated fatty alcohol alcohols, starch fatty acids, fatty acid alcohol fatty acids, starch alcohols, oxyethylated fatty alcohol fatty alcohols, fatty acid alcohol starches, furthermore Cellulose derivatives, perfumes, hair pretreatment agents, conditioners, hair swelling agents, preservatives, petroleum jelly, paraffin oil and fatty acids as well as care products such as cationic resins, lanolinders derivatives, cholesterol, pantothenic acid and betaine. The constituents mentioned are used in the amounts customary for such purposes, for example the wetting agents and emulsifiers in concentrations of about 0.5 to 30 percent by weight (based on the colorant), the thickeners in an amount of about 0.1 to 25 percent by weight ( based on the colorant) and the care substances in a concentration of about 0.1 to 5.0 percent by weight (based on the colorant).
Der pH-Wert des gebrauchsfertigen Haarfärbemittels beträgt in der Regel 3 bis 10,5, vorzugsweise 5 bis 9. Zur Einstellung des geeigneten pH-Wertes können alkalisierende Mittel wie Alkanolamine, Alkylamine, Alkalihydroxide oder Ammoniumhydroxid und Alkalicarbonate oder Ammoniumcarbonate, oder Säuren wie Milchsäure, Essigsäure, Weinsäure, Phosphorsäure, Salzsäure, Zitronensäure, Ascorbinsäure und Borsäure, eingesetzt werden.The pH of the ready-to-use hair dye is usually 3 to 10.5, preferably 5 to 9. Alkalizing agents such as alkanolamines, alkylamines, alkali metal hydroxides or ammonium hydroxide and alkali metal carbonates or ammonium carbonates, or acids such as lactic acid, acetic acid, tartaric acid, phosphoric acid, hydrochloric acid, citric acid, ascorbic acid and boric acid, can be used to adjust the suitable pH.
Das Färbemittel wird auf das Haar aufgetragen. Je nach gewünschter Farbtiefe läßt man diese Mischung 5 bis 60 Minuten, vorzugsweise 15 bis 30 Minuten, bei einer Temperatur von 20 bis 50 Grad Celsius, insbesondere bei 30 bis 40 Grad Celsius einwirken. Anschließend wird das Haar mit Wasser gespült und gegebenenfalls mit einem Shampoo gewaschen.The colorant is applied to the hair. Depending on the desired depth of color, this mixture is allowed to act for 5 to 60 minutes, preferably 15 to 30 minutes, at a temperature of 20 to 50 degrees Celsius, in particular at 30 to 40 degrees Celsius. The hair is then rinsed with water and, if necessary, washed with a shampoo.
Die so erhaltene Färbung kann mit dem erfindungsgemäßen Entfärbemittel entfernt werden. Hierzu wird das gefärbte Haar mit dem Entfärbemittel behandelt. Die Einwirkungszeit des Entfärbemittels beträgt je nach zu entfärbender Färbung und Temperatur (etwa 20 bis 50 Grad Celsius) 5 bis 60 Minuten, insbesondere 15 bis 45 Minuten, wobei durch Wärmezufuhr der Entfärbeprozeß beschleunigt werden kann. Nach Beendigung der Einwirkungszeit des Entfärbemittels wird das Haar mit Wasser gespült, gegebenenfalls mit einem Shampoo gewaschen, und sodann getrocknet.The coloring obtained in this way can be removed using the decolorizing agent according to the invention. For this, the colored hair is treated with the decolorizing agent. The exposure time of the decolorizing agent is 5 to 60 minutes, in particular 15 to 45 minutes, depending on the color and temperature to be decolorized (about 20 to 50 degrees Celsius), the decolorization process being accelerated by the application of heat. After the exposure time of the decolorizing agent has ended, the hair is rinsed with water, optionally washed with a shampoo, and then dried.
Die Anwendung des erfindungsgemäßen Entfärbemittels ist natürlich nicht auf die Entfärbung der mit der Komponente (I) des erfindungsgemäßen Mehrkomponenten-Kits erzeugten Färbungen beschränkt. Vielmehr kann die erfindungsgemäße Entfärbezubereitung in der vorstehend beschriebenen Verfahrensweise ganz allgemein zur Entfärbung von mit direktziehenden Farbstoffen erhaltenen Färbungen eingesetzt werden, auch wenn diese nicht mit Hilfe des erfindungsgemäßen Färbemittels der Komponente (I) , sondern auf einem ganz anderen und unabhängigen Weg erzeugt wurden. Darüber hinaus eignet sich die erfindungsgemäße Entfärbezubereitung auch zur Entfärbung von anderen natürlichen oder synthetischen Fasern wie zum Beispiel Baumwolle, Wolle, Seide, Viskose, Nylon, Celluloseacetat, sofern diese mit direktziehenden Farbstoffen gefärbt worden sind, und ist nicht auf die Entfärbung von Keratinfasern wie menschlichen Haaren beschränkt.The use of the decolorizing agent according to the invention is of course not restricted to the decolorization of the colorations produced with component (I) of the multicomponent kit according to the invention. Rather, the decolorization preparation according to the invention in the above described procedure can be used in general for decolorization of dyeings obtained with substantive dyes, even if these were not produced using the colorant of component (I) according to the invention, but in a completely different and independent way. In addition, the decolorization preparation according to the invention is also suitable for decolorizing other natural or synthetic fibers such as cotton, wool, silk, viscose, nylon, cellulose acetate, provided that these have been dyed with substantive dyes, and is not designed to decolorize keratin fibers such as human Hair limited.

Die in den vorliegenden Beispielen ermittelten L*a*b*-Farbmesswerte wurden mit einem Farbmessgerät der Firma Minolta, Typ Chromameter II, ermittelt. Hierbei steht der L-Wert für die Helligkeit (das heißt je geringer der L-Wert ist, umso größer ist die Farbintensität), während der a-Wert ein Maß für den Rotanteil ist (das heißt je größer der a-Wert ist, umso größer ist der Rotanteil). Der b-Wert ist ein Maß für den Blauanteil der Farbe, wobei der Blauanteil umso größer ist, je negativer der b-Wert ist.The L * a * b * color measurement values determined in the present examples were determined using a color measuring device from Minolta, type Chromameter II. Here, the L-value stands for the brightness (i.e. the lower the L-value, the greater the color intensity), while the a-value is a measure of the red component (i.e. the larger the a-value, the greater the red component is larger). The b-value is a measure of the blue component of the color, the more negative the b-value, the greater the blue component.
