Description

  • Die vorliegende Erfindung betrifft Mittel zum Färben und/oder Aufhellen keratinischer Fasern, dh Mittel zur Anwendung auf Keratinfasern, insbesondere menschlichen Haaren, und deren Verwendung. The present invention relates to agents for dyeing and / or lightening keratin fibers, ie agents for use on keratin fibers, especially human hair, and its use.
  • Die Veränderung von Form und Farbe der Haare stellt einen wichtigen Bereich der modernen Kosmetik dar. Dadurch kann das Erscheinungsbild der Haare sowohl aktuellen Modeströmungen als auch den individuellen Wünschen der einzelnen Person angepaßt werden. The change of shape and color of hair is an important area of ​​modern cosmetics. Thus, the appearance of the hair can be adapted to both current fashion trends and to the individual needs of each person. Dabei können Dauerwell- und andere die Haarform verändernde Verfahren nahezu unabhängig vom Typ der zu behandelnden Haare eingesetzt werden. Here, perm and other hair shape can changing process is nearly independent of the used hair to be treated type. Dagegen sind Färbe- und Blondierverfahren auf bestimmte Ausgangshaarfarben begrenzt. In contrast, dyeing and blonding are restricted to certain output hair colors. So eignen sich für aufhellende Verfahren, die sogenannten Blondierverfahren, im wesentlichen nur dunkelblonde oder hellere Haare. So are suitable for whitening method, called blonding, essentially only dark blonde or light colored hair. Die Grundlagen der Blondierverfahren sind dem Fachmann bekannt und können in einschlägigen Monographien, zB von Kh. Schrader, Grundlagen und Rezepturen der Kosmetika, 2. Auflage, 1989, Dr. The basics of blonding are known in the art and can be used in relevant monographs, eg Kh. Schrader, bases and Formulations of Cosmetics, 2nd edition, 1989, Dr. Alfred Hüthig Verlag, Heidelberg, oder W. Umbach (Hrg.), Kosmetik, 2. Auflage, 1995, Georg Thieme Verlag, Stuttgart, New York, nachgelesen werden. Alfred Hüthig Verlag, Heidelberg, or W. Umbach (ed.), Cosmetics, 2nd edition, 1995, Georg Thieme Verlag, Stuttgart, New York, be found.
  • Gleichzeitig besteht aber auch vielfach der Wunsch, die Haarfarbe zu ändern und zusammen mit der Haarfärbung auch eine Aufhellung des zu färbenden Haares, die sich auch als erhöhter Glanz bemerkbar macht, zu erreichen. At the same time, there is also often a desire to change the hair color and to achieve together with the hair coloring and lightening of the hair to be dyed, which manifests itself as higher gloss.
  • Konventionelle Haarfärbemittel bestehen in der Regel aus mindestens einer Entwickler- und mindestens einer Kupplersubstanz und enthalten ggf. noch direktziehende Farbstoffe als Nuanceure. Conventional hair dyes are generally of at least one developing and at least one coupling substance and optionally also contain direct dyes as shading agents. Kuppler- und Entwicklerkomponenten werden auch als Oxidationsfarbstoffvorprodukte bezeichnet. Coupler and developer components are also referred to as oxidation dye precursors.
  • Vor ihrer Anwendung auf menschliches Haar werden Haarfärbe- und/oder -aufhellungsmittel in fester oder pastöser Form mit verdünnter wäßriger Wasserstoffperoxid-Lösung vermischt. Before its application to human hair hair coloring and / or lightening agents are mixed in solid or pasty form with dilute aqueous hydrogen peroxide solution. Diese Mischung wird dann auf das Haar aufgebracht und nach einer bestimmten Einwirkzeit wieder ausgespült. This mixture is then applied to the hair and rinsed out again after a certain contact time. Die Einwirkungsdauer auf dem Haar zur Erzielung einer vollständigen Ausfärbung bzw. Aufhellung liegt zwischen etwa 30 und 40 Minuten. The period of action on the hair to achieve complete dyeing or whitening is between about 30 and 40 minutes. Es ist naheliegend, daß bei den Benutzern dieser Haarfarben oder Blondiermittel ein Bedürfnis besteht, diese Einwirkungszeit zu verringern. It is obvious that when the users of the hair color or hair bleaching is a need to reduce this exposure time.
  • Weder die pastenförmigen noch die pulverförmigen Färbe- und/oder Blondiermittel, die heute auf dem Markt sind, können als optimal angesehen werden. Neither the pasty nor the powdery coloring and / or bleaching that are on the market today can be considered optimal. Während die Färbe- und/oder Blondierwirkung auf dem Haar als befriedigend bezeichnet werden kann, bestehen doch noch eine Reihe von Nachteilen und Problemen sowohl bei Herstellung als auch bei der Handhabung dieser Mittel. While the dyeing and / or bleaching can be referred to on the hair as satisfactory, but there are still a number of disadvantages and problems both in production and in the use of these funds.
  • Die für die Färbung und/oder Aufhellung von Keratinmaterialien verwendeten Systeme enthalten als Lösungsmittel nahezu ausschließlich Wasser oder Gemische von Wasser mit niedermolekularen Alkoholen wie beispielsweise Ethanol oder Isopropanol. The systems used for dyeing and / or lightening keratin materials contain as the solvent almost exclusively water or mixtures of water with low molecular weight alcohols such as ethanol or isopropanol. Für die Wahl solcher Lösungsmittel spielen zum einen physiologische Gesichtspunkte eine Rolle, zum anderen ist eine Anfärbung im Haarinneren nur bei einem geeigneten Transportmedium sowie eine Reaktion in reaktionsfähigen Systemen nur bei geeignetem Reaktionsmedium möglich. For the election of such solvents a physiological aspects play a role for, and secondly to dye the hair inside is only possible if a suitable transport medium and a reaction in reactive systems only suitable reaction medium. Allerdings hat der Einsatz dieser Lösungsmittel auch Nachteile. However, the use of these solvents has disadvantages. So unterliegen Farbstoffe und deren Vorprodukte bei Lagerung in wäßrigen oder wäßrig-alkoholischen Systemen der Solvolyse oder neigen zur Sedimentation. So subject dyes and their precursors when stored in aqueous or aqueous-alcoholic systems solvolysis or tend to sediment. Diese Nachteile können prinzipiell durch Lagerung in Pulverform und Anmischen der Applikationsform durch die Anwenderin überwunden werden, allerdings läßt dann oft die für ein einheitliches gutes Ergebnis notwendige Dispergierung und Sedinmentationsstabilität zu wünschen übrig. These disadvantages can be overcome by storing in powder form and mixing of the application form by The woman in principle, but then often leaves necessary for a consistent good result dispersion and Sedinmentationsstabilität to be desired. Aus diesen Gründen bietet sich eine stabile feinteilige Dispergierung der Inhaltstoffe in inerten Flüssigkeiten an. For these reasons, a stable fine dispersion of ingredients offers in inert liquids. Leider sind einige der in Haarfärbemitteln und/oder Blondierpasten eingesetzten Strukturgeber substantiv zu Haar, so daß sie nach der kosmetischen Anwendung nur schwer vom Haar zu entfernen sind. Unfortunately, some of the texturing agent used in hair dye and / or Blondierpasten are substantive to hair, so that they are difficult to remove after the cosmetic treatment of the hair. Dies führt zumeist zu einer unangenehmen „Beschwerung des Haares", die ua einen schlechteren Halt der Frisur bewirkt. This usually leads to an unpleasant "weigh down the hair," which causes, among other things poorer hold of the hairstyle.
  • Der vorliegenden Erfindung lag die Aufgabe zugrunde, die genannten Nachteile zu überwinden. The present invention was based on the object to overcome the disadvantages mentioned. Dabei sollten Mittel zum Färben und/oder Aufhellen keratinischer Fasern bereitgestellt werden, die sedimentationsstabil sind und in denen die Inhaltsstoffe bei Lagerung nicht durch Solvolyse oder chemische Reaktionen beeinträchtigt werden. In this case, agent for dyeing and / or lightening keratin fibers should be provided which are stable to sedimentation, and in which the ingredients upon storage are not affected by solvolysis or chemical reactions.
  • Zusätzlich sollten sich Komponenten einarbeiten lassen, die beim Vermischen mit Wasser Hydratationsenergie freisetzen und aufgrund der damit verbundenen Wärmeentwicklung zu einem verbesserten Farbaufzug oder einer verbesserten Aufhellwirkung führen, wie beispielsweise Calciumchlorid, Magnesiumsulfat, Zeolithe, usw.. In addition, should the components can be incorporated which release hydration when mixed with water, and due to the associated heat generation in an improved color elevator or an improved whitening effect, such as calcium chloride, magnesium sulfate, zeolites, etc ..
  • Es wurde nun überraschenderweise gefunden, daß sich Mittel zum Färben und/oder Aufhellen keratinischer Fasern mit verbessertem Sedimentationsverhalten, sehr guter Lagerfähigkeit und weiteren vorteilhaften Eigenschaften herstellen lassen, wenn diese Mittel wasserarm bzw. -frei formuliert werden und bestimmte Substanzen aus der Gruppe der ionischen Flüssigkeiten enthalten. It has now been found, surprisingly, that agent for dyeing and / or lightening keratin fibers with improved sedimentation, very possible to produce good storage stability and other advantageous properties when these agents are formulated wasserarm or -free and certain substances from the group of ionic liquids contain.
