Description

Verfahren zur Verbesserung strukturgeschädigter Haare Haare, die wiederholt einer Kaitwellenbehandlung, Blondierung oder verschiedenartigen Färbeverfahren unterworfen werden, zeigen häufig Erscheinungen wie Haarspitzaufspaltung (Trichoptilosis), geraden Haarbruch (Trichoclasie), Haarknötchenbildung (Trichorrhexis nodosa), Störungen der natürlichen Entfettungsfunktionen sowie Abspreizung der Haaroberhäutchen (Epidermicula), wodurch der natürliche Glanz verschwindet und die Haare stumpf und matt werden.Method for improving structurally damaged hair Hair that repeats subjected to a wave treatment, bleaching or various coloring processes often show symptoms such as hair tip splitting (trichoptilosis), straight Hair breakage (trichoclasia), hair knot formation (trichorrhexis nodosa), disorders the natural degreasing functions as well as splaying of the hair cuticles (epidermicula), whereby the natural shine disappears and the hair becomes dull and dull.

Um die Lichtreflexion solcher geschädigten Haare durch Glättung der Oberfläche zu verbessern, wurden bisher verschiedene Verfahren angewandt. Spülungen mit verdünnter Gerbsäurelösung wurden vorgenommen oder die Haare wurden mit Milch- oder Zitronensäure enthaltenden Präparaten in Gegenwart von oberflächenaktiven Stoffen behandelt. Dabei ist die oberflächenglättende Wirkung solcher adstringierender Substanzen besonders dann groß, wenn diese auf der Haaroberfläche haftenbleiben. To reduce the light reflection of such damaged hair by straightening the Various methods have heretofore been used to improve the surface. Douches with diluted tannic acid solution were made or the hair was treated with milk or preparations containing citric acid in the presence of surfactants treated. The surface-smoothing effect of such astringent substances is here especially when they stick to the surface of the hair.

Gegenstand der Erfindung ist ein Verfahren zur Verbesserung strukturgeschädigter Haare, bei dem die stumpfen, unansehnlichen Haare dauerhaft in ihrer Oberfläche geglättet und gefestigt werden. The invention relates to a method for improving structurally damaged Hair in which the dull, unsightly hair is permanently on its surface be smoothed and strengthened.

Dies wird erfindungsgemäß dadurch erreicht, daß die Haare mit der Lösung einer Maleinsäure bzw. ihrer Substitutionsprodukte, beispielsweise Methyl-, Athyl-, Propyl- oder Methyl-Propyl-Maleins äure behandelt werden. Sie werden vorzugsweise in wäßriger Lösung und in einer Konzentration von 0,3 bis 40/0, insbesondere 2,5 O/o, eingesetzt. This is achieved according to the invention in that the hair with the Solution of a maleic acid or its substitution products, for example methyl, Ethyl, propyl or methyl propyl maleic acid are treated. You will preferably in aqueous solution and in a concentration of 0.3 to 40/0, in particular 2.5 O / o, inserted.

Als wesentlichen Fortschritt gegenüber den bekannten Verfahren wird bei der Behandlung mit den angegebenen ungesättigten Verbindungen ein festes, substantielles Aufziehen auf die Haarrindenschicht erzielt und damit eine dauerhafte Glättung der Oberfläche erreicht. Die besonders feste Haftung der erfindungsgemäß verwendeten Verbindungen auf den Haaren deutet darauf hin, daß über reine Adsorptionskräfte hinaus chemische Bindungen durch Reaktion der C-C-Doppelbindungen mit den Amino-und Hydroxylgruppen der Hornsubstanzen entstanden sind. As a significant advance over the known method is when treated with the unsaturated compounds specified, a solid, substantial one Pulling up on the hair bark layer is achieved and thus a permanent smoothing of the Surface reached. The particularly strong adhesion of those used according to the invention Compounds on the hair suggests that they are purely adsorptive In addition, chemical bonds through reaction of the C-C double bonds with the amino and Hydroxyl groups of the horny substances have arisen.

Weiterhin wirken die erfindungsgemäßen Verbindungen als ungesättigte Verbindungen der für die Haaroberfläche schädlichen Nachoxydation nach einer Blondierung entgegen, indem sie mit den in den Haaren verbliebenen Peroxyden zu Oxysäuren bzw. Peroxysäuren reagieren, die wie die olefinischen Verbindungen eine adstringierende Wirkung zeigen und damit dem gleichen gewünschten Zweck der Oberflächenglättung dienen. The compounds according to the invention also act as unsaturated Compounds of post-oxidation, which is harmful to the hair surface, after bleaching by reacting with the peroxides remaining in the hair to form oxyacids or Peroxy acids react, which like the olefinic compounds have an astringent Show effect and thus the same desired purpose of surface smoothing to serve.

Die nach dem neuen Verfahren behandelten Haare können in feuchtem Zustand leicht und ohne abzubrechen durchgekämmt werden. The hair treated according to the new method can be damp Can be combed through easily and without breaking off.

Günstig für die Benetzung der Haare mit der Behandlungslösung ist ein Zusatz einer oberflächenaktiven Substanz, beispielsweise Laurylpyridiniumchlorid. Is beneficial for wetting the hair with the treatment solution an addition of a surfactant such as lauryl pyridinium chloride.

Um das Aufziehen der ungesättigten Säuren auf die Hornsubstanzen zu erleichtern, können der zur Behandlung verwendeten Lösung Puffersubstanzen zugesetzt werden, beispielsweise Glykokoll, wodurch ein pH-Wert von 1,9 bis 4,0, vorzugsweise 2,5, aufrechterhalten wird. About the absorption of the unsaturated acids on the horny substances To facilitate the treatment, buffer substances can be added to the solution used for the treatment be, for example glycocoll, creating a pH of 1.9 to 4.0, preferably 2.5, is maintained.

Darüber hinaus zeigen die Zusätze von Glycerindi-oder -monostearat durch Emulsionsbildung einen günstigen Einfluß auf die Wirkung der Behandlungslösung. In addition, the additions of glycerol di- or monostearate show a favorable influence on the action of the treatment solution by emulsification.

Ein Zusatz von Zuckersubstanzen, beispielsweise Rohrzucker, Milchzucker oder deren Derivaten, verbessert die mechanischen Eigenschaften der Haare nach der Behandlung. An addition of sugar substances, for example cane sugar, milk sugar or their derivatives, improves the mechanical properties of the hair after Treatment.

Die vorliegende Erfindung führt zu einer erstaunlichen Strukturverbesserung der Haaroberfläche, wobei durch die unkomplizierte Anwendung preiswerter Substanzen auch ein wirtschaftlicher Fortschritt erzielt wird. The present invention leads to an astonishing structural improvement the hair surface, whereby by the uncomplicated application of inexpensive substances economic progress is also achieved.

Die Erfindung wird im folgenden durch einige Ausführungsbeispiele erläutert, bei denen als ungesättigte mehrbasige Carbonsäuren Maleinsäuren verwendet sind. The invention is illustrated in the following by means of some exemplary embodiments explained in which maleic acids are used as unsaturated polybasic carboxylic acids are.

Beispiel 1 2,5 g Methylmaleinsäure, 0,5 g Laurylpyridiniumchlorid, 0,5 g Glykokoll, 0,4 g Glycerinmonostearat, 1,0 g Milchzucker werden mit Wasser auf 100 g aufgefüllt. Die zu behandelnden Haare werden mit der Mischung massiert und unter Verbleiben der Lösung im Haar bei 400 C unter einer Haube getrocknet. Example 1 2.5 g methyl maleic acid, 0.5 g lauryl pyridinium chloride, 0.5 g glycocolla, 0.4 g glycerol monostearate, 1.0 g lactose are mixed with water made up to 100 g. The hair to be treated is massaged with the mixture and dried under a hood at 400 ° C. while the solution remained in the hair.

Beispiel 2 2,5 g Äthylmaleinsäure, 0,2 g Laurylpyridiniumchlorid, 0,4 g Glykokoll, 0,4 g Glycerindistearat und 1,0 g Milchzucker werden mit Wasser auf 100 g aufgefüllt und wie unter Beispiel 1 verwendet. Example 2 2.5 g of ethyl maleic acid, 0.2 g of laurylpyridinium chloride, 0.4 g of glycocolla, 0.4 g of glycerol distearate and 1.0 g of lactose are mixed with water made up to 100 g and used as in Example 1.

Beispiel 3 2,0 g Methylmaleinsäure, 1,0 g quartäre Ammoniumverbindung, 0,8 g Glykokoll, 0,5 g Glycerinmono- bzw. -distearat und 0,5 g Rohrzucker werden mit Wasser auf 100 g aufgefüllt und wie unter Beispiel 1 verwendet. Example 3 2.0 g of methyl maleic acid, 1.0 g of quaternary ammonium compound, 0.8 g glycocolla, 0.5 g glycerol mono- or distearate and 0.5 g cane sugar Made up to 100 g with water and used as in Example 1.
