A-8/98 Haarfärbemittel A-8/98 Hair dyes
Die vorliegende Erfindung betrifft Haarfärbemittel auf Basis einer wäßrigen Emulsion, enthaltend mindestens ein Oxidationsfarbstoff-Vorprodukt, insbesondere ein solches in Form einer wäßrigen Emulsion, mit verbesserter Viskositätsstabilität.The present invention relates to hair dyes based on an aqueous emulsion, containing at least one oxidation dye precursor, in particular one in the form of an aqueous emulsion, with improved viscosity stability.
Permanente Haarfärbemittel auf Basis von Oxidationsfarbstoffen erfreuen sich einer weiten Verbreitung. Ihre Anwendung erfolgt in der Regel dergestalt, daß eine flüssige , zumeist als wäßrige Emulsion vorliegende, mindestens ein Oxidationsfarbstoff-Vorprodukt, im allgemeinen mindestens eine Entwickler- und mindestens eine Kupplersubstanz, enthaltende Zusammensetzung unmittelbar vor der Anwendung mit einer Peroxid enthaltenden Zusammensetzung vermischt, und die Mischung auf das Haar aufgebracht wird.Permanent hair dyes based on oxidation dyes are very popular. They are generally used in such a way that a liquid composition, usually in the form of an aqueous emulsion, containing at least one oxidation dye precursor, generally at least one developer and at least one coupler substance, is mixed with a composition containing peroxide immediately before use, and the mixture is applied to the hair.
Dabei ist die Einhaltung gewisser Viskositätsverhältnisse zweckmäßig. Es hat sich jedoch gezeigt, daß diese Emulsionen häufig thixotrope Eigenschaften aufweisen, d.h., bei der Lagerung in der Dose oder Tube ihre Viskosität erhöhen, was dann bei der Applikation und der Vermischung mit der Peroxid-Zusammensetzung Probleme bereitet.It is advisable to maintain certain viscosity ratios. However, it has been shown that these emulsions often have thixotropic properties, i.e. their viscosity increases when stored in the can or tube, which then causes problems when applying and mixing with the peroxide composition.
Die Erfindung geht daher von der Aufgabenstellung aus, diese Probleme zu vermeiden und Haarfärbeemulsionen mit stabiler Viskosität zur Verfugung zu stellen.The invention is therefore based on the task of avoiding these problems and providing hair dye emulsions with stable viscosity.
Erfindungsgemäß wurde festgestellt, daß wäßrige Haarfarbe-Emulsionen, die mindestens ein Oxidationsfarbstoff-Vorprodukt enthalten, dann viskositätsstabil sind, wenn sie ein Gemisch aus 0,5 bis 5 Gew.-% mindestens eines Ethandiol- und/oder l^-Propandiol-Cn-Cao-Fettsäurediesters und 0,5 bis 5 Gew.-% mindestens eines Cio-C2o-Alkylamidobetains, jeweils berechnet auf die Gesamtzusammensetzung der Emulsion, enthalten.According to the invention, it was found that aqueous hair color emulsions containing at least one oxidation dye precursor are viscosity-stable if they contain a mixture of 0.5 to 5% by weight of at least one ethanediol and/or 1^-propanediol Cn-Cao fatty acid diester and 0.5 to 5% by weight of at least one Cio-C2o-alkylamidobetaine, in each case calculated based on the total composition of the emulsion.
Gemäß einer bevorzugten Ausführungsform der Erfindung werden als Ethandiol- bzw. 1,2-Propandiolfettsäurediester die Stearate eingesetzt, doch ist auch die Verwendung der Dilaurate, Dimyristate, Dipalmitate oder Dioleate sowie von Mischestern oder Estergemischen möglich.According to a preferred embodiment of the invention, stearates are used as ethanediol or 1,2-propanediol fatty acid diesters, but the use of dilaurates, dimyristates, dipalmitates or dioleates as well as mixed esters or ester mixtures is also possible.
Die bevorzugte Menge liegt bei etwa 1 bis 2,5, insbesondere bei etwa 2 Gew.-%, berechnet auf die Gesamtzusammensetzung.The preferred amount is about 1 to 2.5, especially about 2 wt.%, calculated on the total composition.
AIs Cio-C2o-Alkylamidopropylbetain wird vorzugsweise Kokosmidopropylbetain in einer Menge von etwa 1 bis 2,5, insbesondere etwa 2 Gew.-%, berechnet auf die Gesamtzusammensetzung, eingesetzt.Cocomidopropylbetaine is preferably used as C10-C20-alkylamidopropylbetaine in an amount of about 1 to 2.5, in particular about 2% by weight, calculated on the total composition.
Das bevorzugte Gewichtsverhältnis beider Komponenten liegt bei 1:3 bis 3:1, insbesondere etwa 1:1.The preferred weight ratio of both components is 1:3 to 3:1, in particular about 1:1.
Gemäß einer weiteren bevorzugten Ausfuhrungsform der Erfindung sind in der Haarfarbe-Emulsion noch 0,5 bis 5, vorzugsweise etwa 1 bis 2,5, insbesondere etwa 2 Gew.-%, berechnet auf die Gesamtzusammensetzung, mindestens eines Cö-Cis-Fettsäuretriglycerids vorhanden.According to a further preferred embodiment of the invention, 0.5 to 5, preferably about 1 to 2.5, in particular about 2% by weight, calculated on the total composition, of at least one C6-C8 fatty acid triglyceride are present in the hair color emulsion.
Als solches wird Caprinsäuretriglycerid bevorzugt, jedoch sind grundsätzlich auch andere Triglyceride verwendbar, z.B., jene von Caprylsäure, Laurinsäure, Myristinsäure oder Palmitinsäure sowie solche von Mischsäuren, z.B. Kokosölfettsäüren.Capric acid triglyceride is preferred as such, but in principle other triglycerides can also be used, e.g. those of caprylic acid, lauric acid, myristic acid or palmitic acid as well as those of mixed acids, e.g. coconut oil fatty acids.
Die sonstigen möglichen Bestandteile der erfindungsgemäßen Haarfärbemittel sind an sich bekannt.The other possible components of the hair dyes according to the invention are known per se.
Diese können üblicherweise weitere Emulgatoren und Tenside, Lösungsvermittler, Verdickungsmittel, haarkonditionierende Substanzen wie Eiweißhydrolysate und synthetische Polymere, Stabilisatoren, Verdünnungsmittel, etc. enthalten.These can usually contain other emulsifiers and surfactants, solubilizers, thickeners, hair conditioning substances such as protein hydrolysates and synthetic polymers, stabilizers, diluents, etc.
Ausführliche Angaben über die Zusammensetzung und Herstellung von Haarfärbemitteln finden sich beispielsweise in der Monographie von K. Schrader, Grundlagen und Rezepturen der Kosmetika (1989, 2. Auflage, Dr. A. Hüthig Verlag), S. 782-815, auf die hier ausdrücklich Bezug genommen wird.Detailed information on the composition and production of hair dyes can be found, for example, in the monograph by K. Schrader, Fundamentals and Recipes of Cosmetics (1989, 2nd edition, Dr. A. Hüthig Verlag), pp. 782-815, to which explicit reference is made here.
Die Anwendung der Oxidationsfarbstoff-Vorprodukte enthaltenden Haarfärbemittel erfolgt durch Vermischen mit Peroxiden, insbesondere Wasserstoffperoxidlösung oder -lotion, unmittelbar vor der Applikation auf das Haar.The application of hair dyes containing oxidation dye precursors is carried out by mixing with peroxides, in particular hydrogen peroxide solution or lotion, immediately before application to the hair.

Die auf das Haar aufzubringende, gebrauchsfertige Färbemischung weist dabei vorzugsweise einen alkalischen pH-Wert im Bereich von 7,5 bis 9,5 auf, jedoch sind auch neutrale und schwach saure Endprodukte geeignet, z.B. im Bereich von etwa 5,5 bis etwa 7,5.The ready-to-use dye mixture to be applied to the hair preferably has an alkaline pH value in the range of 7.5 to 9.5, but neutral and slightly acidic end products are also suitable, e.g. in the range of about 5.5 to about 7.5.
Aus dem älteren deutschen Patent Nr. 197 01 422.4 sind Haarfärbemittel in einer Grundlage bekannt, die 0,25 bis 5 Gew.-% mindestens eines ethoxylierten Cio-C2o-Fettsäurealkanolamids enthalten.From the older German patent no. 197 01 422.4, hair dyes in a base are known which contain 0.25 to 5% by weight of at least one ethoxylated Cio-C2o fatty acid alkanolamide.
Die Mitverwendung solcher ethoxylierten Cio-C20-Fettsäurealkanolamide in der erfindungsgemäßen Zusammensetzung ist vom Schutzumfang ausdrücklich ausgenommen.The use of such ethoxylated C10-C20 fatty acid alkanolamides in the composition according to the invention is expressly excluded from the scope of protection.
Im folgenden wird anhand der Ausfuhrungsbeispiele die Wirkung der erfindungsgemäßen Zusammensetzungen beschrieben.The effect of the compositions according to the invention is described below using the examples.
