Abstract

The invention pertains to a hair dyeing process that uses a two-component hair dye consisting of components (A) and (B) which are packaged separately but combined in one sales unit, component (A) comprising vegetable matter with soluble dyestuff content in a water-insoluble but at least partially water-permeable packet and component (B) comprising at least one thickener for aqueous media. The water-permeably packed component (A) is introduced into a predetermined quantity of an aqueous medium until the dye has dissolved; then the thickener (B) is added to the dye solution. The ready-to-use dye preparation thus obtained is applied directly to the hair and rinsed out after a period of setting.

Description

'Zwei omponenten-Naturhaarfärbemitte1" 'Two component natural hair dye1 "
Die Erfindung betrifft ein neues Verfahren zur Färbung von Haaren unter Verwendung von natürlichen Haarfärbemitteln, vorzugsweise von färbenden Pflanzenteilen und ein für dieses Verfahren geeignetes Haarfärbemittel, bestehend aus einer Verkaufseinheit aus zwei ge¬ trennt verpackten Komponenten, von denen eine färbende Pflanzenteile und die andere ein Verdickungsmittel umfaßt.The invention relates to a new process for coloring hair using natural hair colorants, preferably coloring plant parts, and a hair colorant suitable for this process, consisting of a sales unit consisting of two separately packaged components, one of which coloring plant parts and the other a thickener includes.
Pflanzliche Haarfärbemittel sind zur temporären Haarfärbung seit langem bekannt. Üblicherweise werden dafür gepulverte Pflanzenteile von stark färbenden Pflanzen wie z.B. Henna oder Indigo-Blätter ver¬ wendet, die mit Wasser und ggf. Füllstoffen und Verdickungsmitteln zu Färbepasten angerührt werden, die auf das Haar aufgetragen wer¬ den.Herbal hair dyes have long been known for temporary hair coloring. Powdered parts of plants from strongly coloring plants such as e.g. Henna or indigo leaves are used, which are mixed with water and, if appropriate, fillers and thickeners to give coloring pastes which are applied to the hair.
Dieses altbekannte Kataplasma-Verfahren weist den Nachteil auf, daß die Farbstoffpulver sehr fein vermählen sein müssen, um auf dem Haar eine gleichmäßige Färbung zu erzeugen. Außerdem verbleiben wasserun¬ lösliche Bestandteile auf dem Haar, die nur schwer vollständig aus¬ zuwaschen sind. Eine feine Vermahlung der Farbstoffe hat auch den Nachteil, daß bei der Herstellung und Verarbeitung eine unerwünschte Staubentwicklung stattfindet. Es ist auch schon versucht worden, Naturfarbstoffe aus den Pflanzen¬ teilen zu extrahieren und die Extrakte in Färbezubereitungen einzu¬ arbeiten. Solche aus der Pflanze isolierten Farbstoffe sind aber sehr instabil gegenüber den Einflüssen von Sauerstoff und Licht und eignen sich daher nicht zur Herstellung lagerfähiger Zubereitungen.This well-known cataplasma process has the disadvantage that the dye powders have to be ground very finely in order to produce a uniform color on the hair. In addition, water-insoluble constituents remain on the hair which are difficult to wash out completely. Fine grinding of the dyes also has the disadvantage that undesirable dust development occurs during manufacture and processing. Attempts have also already been made to extract natural dyes from the plant parts and to incorporate the extracts into coloring preparations. Such dyes isolated from the plant are very unstable with respect to the effects of oxygen and light and are therefore not suitable for the production of storable preparations.
Es wurde daher nach einem Haarfärbeverfahren gesucht, das die Nach¬ teile der bekannten Naturhaarfärbeverfahren vermeidet.A hair dyeing process was therefore sought which avoids the disadvantages of the known natural hair dyeing processes.
Gegenstand der Erfindung ist ein Zweikomponenten-Naturhaarfärbemit¬ tel, bestehend aus einer Verkaufseinheit mit zwei getrennt verpack¬ ten Komponenten (A) und (B), wobei die KomponenteThe invention relates to a two-component natural hair dye consisting of a sales unit with two separately packaged components (A) and (B), the component
(A) Pflanzenteile, die in wäßrigem Medium lösliche Farbstoffe abge¬ ben, in einer wasserunlöslichen Verpackung umfaßt, deren Wandung wenigstens teilweise aus porösem, für Wasser und gelöste Farb¬ stoffe durchlässigem Material besteht, und die Komponente(A) parts of plants which give off dyes soluble in aqueous medium, in a water-insoluble packaging, the wall of which at least partially consists of porous material which is permeable to water and dissolved dyes, and the component
(B) wenigstens ein separat verpacktes Verdickungsmittel für wäßrige Medien umfaßt.(B) comprises at least one separately packaged aqueous media thickener.
Das erfindungsgemäße Verfahren zur Färbung der Haare unter Verwen¬ dung der vorgenannten Zweikomponenten-Haarfärbemittel zeichnet sich dadurch aus, daß man Pflanzenteile, die in wäßrigem Medium lösliche Farbstoffe abgeben, in einer wasserunlöslichen Verpackung, deren Wandung wenigstens teilweise aus porösem, für Wasser und gelöste Farbstoffe durchlässigem Material besteht (Komponente A) in eine vorgegebene Menge eines wäßrigen Mediums einbringt und, gegebenen¬ falls unter Bewegung, darin solange beläßt, bis die gewünschte Farb¬ stoffmenge herausgelöst ist, dann der wäßrigen Farbstofflösung ein wasserlösliches Verdickungsmittel (Komponente B) in einer Menge zu¬ setzt, die dieser eine für die Aufbringung auf das Haar geeignete Viskosität verleiht, und schießlich die verdickte Farbstofflösung auf das Haar aufbringt und nach einer Einwirkungszeit das. gefärbte Haar mit Wasser spült. Durch dieses erfindungsgemäße Verfahren wird erreicht, daß keine unlöslichen Pflanzenteile auf das Haar gelangen und daß die Färbung mit einem frisch bereiteten Farbstoffextrakt erfolgt, der noch kei¬ nen oxidativen Abbau und keine photochemische Zersetzung erlitten hat.The process according to the invention for coloring the hair using the abovementioned two-component hair colorants is distinguished by the fact that parts of the plant which give off dyes which are soluble in an aqueous medium are in a water-insoluble packaging, the walls of which are at least partially made of porous dyes for water and dissolved dyes permeable material consists (component A) in a predetermined amount of an aqueous medium and, if necessary with agitation, remains in it until the desired amount of dye is dissolved, then the aqueous dye solution contains a water-soluble thickener (component B) in an amount zu¬ sets, which gives this a suitable for application to the hair viscosity, and finally applies the thickened dye solution to the hair and rinses the colored hair with water after an exposure time. This process according to the invention ensures that no insoluble parts of the plant get onto the hair and that the dyeing is carried out using a freshly prepared dye extract which has not yet suffered from oxidative degradation and has not undergone photochemical decomposition.
Erfindungsgemäß eignen sich alle stark färbenden Pflanzen oder Pflanzenteile zur Herstellung der Komponente (A) des Zweikomponen¬ ten-Naturhaarfärbemittels. Als Beispiele solcher Pflanzen oder Pflanzenteile seien genannt:According to the invention, all strongly coloring plants or parts of plants are suitable for producing component (A) of the two-component natural hair dye.

Zahlreiche weitere Pflanzen eignen sich als Farbstoffträger zur Her¬ stellung der erfindungsgemäßen Haarfärbemittel. Zusätzlich zu den zerkleinerten Pflanzenteilen können auch andere Farbstoffträger ent¬ halten sein, z.B. Cochenille, Torf oder andere färbende Naturstoffe.Numerous other plants are suitable as dye carriers for the preparation of the hair colorants according to the invention. In addition to the shredded parts of plants can also contain other dye carriers, for example cochineal, peat or other coloring natural substances.
Bevorzugt liegen die Pflanzenteile der Komponente (A) in Form ge¬ trockneter Pulver von Henna, Indigo, Cassia, Schwarztee, Kamillen¬ blüten, Rote Beete, Holunderbeeren, Faulbaumrinde, Blauholz, Rot¬ holz, Curcuma, Salbei oder Rhabarberwurzel vor.The plant parts of component (A) are preferably in the form of dried powders of henna, indigo, cassia, black tea, chamomile flowers, beetroot, elderberries, rot tree bark, blue wood, redwood, curcuma, sage or rhubarb root.
Die zu verwendenden Pflanzen oder Pflanzenteile brauchen nur grob zerkleinert werden, es eignen sich aber auch fein vermahlene Pulver. Ein Stauben kann bei der Anwendung nicht auftreten, da die Pflan¬ zenteile in der Verpackung bleiben. Bevorzugt eignen sich Pflanzen¬ teile, die eine Teilchengröße von 1 μm bis 1 mm aufweisen. Feinere Pulver sind wegen der großen Oberfläche weniger lagerstabil, gröbere Pflanzenteile benötigen eine längere Zeit zum Herauslösen des Farb¬ stoffs.The plants or parts of plants to be used only need to be roughly crushed, but finely ground powders are also suitable. Dusting cannot occur during use because the plant parts remain in the packaging. Plant parts which have a particle size of 1 μm to 1 mm are preferred. Due to the large surface area, finer powders are less stable in storage, coarser parts of plants take a longer time to remove the dye.
Als wasserunlösliche Verpackung eignet sich an sich jedes wasser¬ feste Verpackungsmaterial, gleichgültig ob steif oder flexibel, ob aus wasserfestem Papier, Kunststoff oder Textil. Wichtig ist jedoch, daß die Wandung wenigstens teilweise aus porösem Material besteht. Bevorzugt ist die Verpackung der Komponente (A) ein flexibler Beutel aus einem wasserfesten, aber feinporigen Papier (z.B. Heißfilterpa¬ pier), Vliesstoff oder Textilgewebe. Geeignete Papierbeutel sind z.B. für die Bereitung von Tee (sog. Teebeutel) bekannt.Any water-resistant packaging material is suitable as water-insoluble packaging, irrespective of whether it is rigid or flexible, whether made of water-resistant paper, plastic or textile. However, it is important that the wall consists at least partially of porous material. The packaging of component (A) is preferably a flexible bag made of a waterproof but fine-pored paper (e.g. hot filter paper), nonwoven fabric or textile fabric. Suitable paper bags are e.g. known for the preparation of tea (so-called tea bags).
Bezüglich der Porengröße ist zu beachten, daß ungelöstes Pflanzen¬ material nicht durch die Poren hindurchtreten kann, daher sollte die Porengröße in jedem Falle geringer sein als die Teilchengröße des Feinanteils der verwendeten Pflanzenteile. Für die gelösten Farb¬ stoffe sollte das Verpackungsmaterial hingegen leicht durchlässig sein, damit der Vorgang des Herauslösens der Farbstoffe möglichst rasch ablaufen kann.With regard to the pore size, it should be noted that undissolved plant material cannot pass through the pores, so the pore size should in any case be smaller than the particle size of the fine fraction of the plant parts used. In contrast, the packaging material should be slightly permeable to the dissolved dyes be so that the process of removing the dyes can proceed as quickly as possible.
Außer den mehr oder weniger zerkleinerten Pflanzenteilen können in der wasserunlöslichen Verpackung der Komponente (A) noch weitere wasserlösliche Hilfsmittel enthalten sein, die den Vorgang des Her¬ auslösens der Farbstoffe, die Ausbildung brillanter Färbungen, den Farbaufzug auf die Keratinfaser oder die Stabilität der Färbelösung und des Farbstoffes auf dem Haar verbessern. Solche Hilfsmittel kön¬ nen z.B. pH-Stellmittel oder Puffersubstanzen sein, die der Farb¬ stofflösung den pH-Wert verleihen, bei dem der Farbstoff am inten¬ sivsten ist. Geeignete Produkte sind vor allem z.B. Fruchtsäuren, wie z.B. Citronensäure oder Weinsäure und deren Salze.In addition to the more or less shredded plant parts, the water-insoluble packaging of component (A) may also contain other water-soluble auxiliaries which relate to the process of leaching out the dyes, the formation of brilliant dyeings, the dyeing onto the keratin fiber or the stability of the dyeing solution and improve the dye on the hair. Such aids can e.g. pH adjusting agents or buffer substances which give the dye solution the pH at which the dye is most intensive. Suitable products are primarily e.g. Fruit acids, e.g. Citric acid or tartaric acid and its salts.
Weitere geeignete Hilfsmittel, die mit den Pflanzenteilen der Kom¬ ponente (A) verpackt sein können, sind z.B. wasserlösliche Antioxi- dantien, z.B. Ascorbinsäure, wasserlösliche hydrotrope Stoffe oder Salze wie z.B. Harnstoff, Proteinhydrolysate, Arnmoniumsulfat oder A moniumlactat und oberflächenaktive Stoffe, z.B. pulverförmige Netzmittel wie z.B. Saponine oder synthetische Tenside.Other suitable auxiliaries that can be packed with the plant parts of component (A) are e.g. water soluble antioxidants, e.g. Ascorbic acid, water-soluble hydrotropes or salts such as e.g. Urea, protein hydrolyzates, ammonium sulfate or ammonium lactate and surfactants, e.g. powdery wetting agents such as Saponins or synthetic surfactants.
Die zweite, separat verpackte Komponente (B) enthält wenigstens ein wasserlösliches Verdickungsmittel. Dabei kann sowohl ein festes wie ein flüssiges Verdickungsmittel eingesetzt werden. An die Verpackung der Komponente (B) sind keine besonderen Anforderungen zu stellen außer der, daß sie das jeweilige Verdickungsmittel hinreichend ein¬ schließen soll. Wenn als Verdickungsmittel z.B. eine wäßrige oder sonstige flüssige Zubereitung gewählt wird, so muß die Verpackung wasserdicht und ggf. gegenüber enthaltenen Lösungsmitteln stabil sein.The second, separately packaged component (B) contains at least one water-soluble thickener. Both a solid and a liquid thickener can be used. No particular requirements are to be placed on the packaging of component (B) except that it should sufficiently include the respective thickener. If as a thickener e.g. If an aqueous or other liquid preparation is selected, the packaging must be watertight and, if necessary, stable against the solvents it contains.
Als Verdickungsmittel (B) kann an sich jedes zur Verdickung. wäßriger Medien geeignete und physiologisch verträgliche Verdickungsmittel verwendet werden. Geeignet sind sowohl wasserunlösliche Quellmittel wie z.B. Schichtsilikate oder kolloidale Verdickungskieselsäuren als auch wasserlösliche organische Hydrocolloide, z.B. Naturgu me und Biopolymere sowie synthetische wasserlösliche Polymere.As a thickener (B), any thickener can be used. aqueous media suitable and physiologically compatible thickeners be used. Both water-insoluble swelling agents such as layered silicates or colloidal thickening silicas are suitable, as are water-soluble organic hydrocolloids, for example natural rubber and biopolymers, and synthetic water-soluble polymers.
Weiterhin eignen sich auch z.B. emulgierfähige Fettkomponenten oder Emulsionskonzentrate, die durch Einrühren in die wäßrige Farbstoff¬ lösung diese in eine dickflüssige Emulsion überführen.Furthermore, e.g. emulsifiable fat components or emulsion concentrates, which are converted into a viscous emulsion by stirring into the aqueous dye solution.
Bevorzugt geeignete Verdickungsmittel zur Ausführung der vorliegen¬ den Erfindung sind jedoch die organischen Naturprodukte aus der Gruppe Guarmehl, Johannisbrotkernmehl, Gummi arabicum, Alginate, wasserlösliche Stärke, Pektin, Gelatine oder Biopolymere wie z.B. Xanthan-Gum.Preferred suitable thickeners for carrying out the present invention are, however, the organic natural products from the group of guar flour, locust bean gum, gum arabic, alginates, water-soluble starch, pectin, gelatin or biopolymers such as e.g. Xanthan gum.
Weitere geeignete Naturstoffderivate sind z.B. die wasserlöslichen Cellulose-, Stärke- oder Guar-Derivate, z.B. Methylcellulose, Hydro- xyethylcellulose, Carboxymethylcellulose, Carboxyethylstärke, Hy- droxypropylguar u.a.Other suitable natural product derivatives are e.g. the water-soluble cellulose, starch or guar derivatives, e.g. Methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, carboxyethyl starch, hydroxypropyl guar and others.
Zur Herstellung der gebrauchsfertigen Haarfärbezubereitung aus den Komponenten (A) und (B) sind diese bevorzugt in einer Verkaufsein¬ heit zusammengefaßt. Dabei sind die Mengen der Komponente (A) und (B) so aufeinander abgestimmt, daß mit einer vorgegebenen Wasser¬ menge sowohl die gewünschte Farbstoffkonzentration zur Haaranfärbung als auch die geeignete Viskosität der Färbelösung zur Aufbringung auf das Haar, z.B. mit einem Färbepinsel erreicht wird.To produce the ready-to-use hair dye preparation from components (A) and (B), these are preferably combined in one sales unit. The amounts of components (A) and (B) are matched to one another in such a way that, with a given amount of water, both the desired dye concentration for hair coloring and the suitable viscosity of the coloring solution for application to the hair, e.g. is achieved with a coloring brush.
Die Konzentration des Farbstoffs in der Färbelösung und damit die Intensität der Haarfärbung kann aber auch vom Anwender noch dadurch gesteuert werden, daß er durch eine kürzere Lösezeit die Menge des gelösten Farbstoffes begrenzt. Die Menge des Verdickungsmittels in der separat verpackten Komponen¬ te (B) sollte so bemessen sein, daß die nach Gebrauchsanweisung ge¬ fertigte gebrauchsfertige Haarfärbezubereitung eine Viskosität im Bereich von 5 bis 50 Pa»s (20°C) (gemessen bei einer Scherspannung (D) von 3 see"1, z.B. im Haake Rotationsviskosimeter Type RV12/MV1) aufweist. Bevorzugt sind weiterhin solche Verdickungsmittel, die zusätzlich zur genannten Viskosität eine gewisse Thixotropie erzeu¬ gen, die eine Haftung der aufgebrachten Färbezubereitung am Haar begünstigt und das Herablaufen des Färbemittels und eine unerwünsch¬ te Hautanfärbung verhindert.The concentration of the dye in the coloring solution and thus the intensity of the hair coloring can also be controlled by the user by limiting the amount of dissolved dye by a shorter dissolving time. Te The amount of thickener in the separately packaged Komponen¬ (B) should be such that the ge according to instructions ready Haarfärbezubereitung produced a viscosity in the range of 5 to 50 Pa »s (20 ° C) (measured at a shear stress ( D) of 3 see " 1 , for example in the Haake rotation viscometer type RV12 / MV1). Preferred furthermore are those thickeners which, in addition to the viscosity mentioned, produce a certain thixotropy which promotes adhesion of the dye preparation applied to the hair and the running down of the Colorant and an undesirable skin staining prevented.
Zusätzlich zu dem Verdickungsmittel können auch weitere Hilfsmittel der Komponente B zugegeben werden, die z.B. die Auflösbarkeit des Verdickungsmittels erleichtern oder die Theologischen Eigenschaften der gebrauchsfertigen Haarfärbezubereitung günstig beeinflussen. Schließlich können auch Duftstoffe, Deodorantien, haarkosmetische Wirkstoffe und Konservierungsmittel zugesetzt werden.In addition to the thickener, other auxiliaries of component B can also be added, e.g. facilitate the dissolvability of the thickener or favorably influence the theological properties of the ready-to-use hair dye preparation. Finally, fragrances, deodorants, hair cosmetic agents and preservatives can also be added.
Es sollte im allgemeinen ausreichen, auf 10 bis 20 g des Pflanzen¬ materials 50 bis 100 g Wasser und 0,5 bis 5 g eines wasserlöslichen Hydrocolloids zur Herstellung einer gebrauchsfertigen Haarfärbezu¬ bereitung vorzusehen.In general, it should be sufficient to provide 50 to 100 g of water and 0.5 to 5 g of a water-soluble hydrocolloid per 10 to 20 g of the plant material for the production of a ready-to-use hair dye preparation.
Zur Herstellung der gebrauchsfertigen Zubereitung wird die Verpa¬ ckung mit den Pflanzenteilen (Komponente A) bevorzugt mit siedend heißem Wasser übergössen, damit die Farbstoffe möglichst rasch und vollständig gelöst werden. Dann bewegt man entweder die Lösung oder den Farbstoffbehälter, damit der Lösevorgang weiter gefördert wird. Wenn man eine möglichst tiefe Färbung erzielen will, läßt man den Farbstoffbehälter bis zum Abkühlen auf Raumtemperatur (20°C) in der Lösung. Man kann aber durch vorzeitiges Entfernen des Farbstoffbe¬ hälters den Extraktionsvorgang der Farbstoffe begrenzen und auf die¬ se Weise eine schwächere Färbung erzielen. Das Verdickungsmittel wird bevorzugt erst nach Abkühlung der Färbe¬ lösung zugesetzt, da es in der heißen Lösung leicht zur Bildung schwer auflösbarer Gel-Klumpen kommt.To produce the ready-to-use preparation, the packaging with the plant parts (component A) is preferably poured with boiling hot water so that the dyes are dissolved as quickly and completely as possible. Then either the solution or the dye container is moved so that the dissolving process is further promoted. If you want to achieve the deepest possible color, leave the dye container in the solution until it cools to room temperature (20 ° C). However, by prematurely removing the dye container, the extraction process of the dyes can be limited and a weaker coloring can be achieved in this way. The thickening agent is preferably added only after the dyeing solution has cooled, since gel clumps which are difficult to dissolve easily form in the hot solution.
Nach Zugabe des Verdickungs ittels muß die Färbezubereitung durch Rühren homogenisiert werden, bis das Verdickungsmittel vollständig verteilt oder gelöst ist und die gewünschte Endviskosität erreicht ist.After the thickener has been added, the coloring preparation must be homogenized by stirring until the thickener has been completely distributed or dissolved and the desired final viscosity has been reached.
Die Aufbringung der gebrauchsfertigen Zubereitung auf das Haar er¬ folgt nach der für die Haarfärbung üblichen Methode, bevorzugt mit einem Pinsel. Man läßt das aufgetragene Präparat dann solange ein¬ wirken, bis der Farbstoff auf das Haar aufgezogen ist. Da die Fär¬ bezubereitung keine unverträglichen Komponenten, z.B. keine unlös¬ lichen Rückstände mehr enthält, kann man die Einwirkungsdauer be¬ liebig lang ausdehnen und z.B. die Zubereitung über Nacht einwirken lassen.The ready-to-use preparation is applied to the hair by the method customary for hair coloring, preferably using a brush. The applied preparation is then left to act until the dye is applied to the hair. Since the dyeing preparation contains no incompatible components, e.g. no longer contains insoluble residues, you can extend the exposure time as long as you like and e.g. let the preparation take effect overnight.
Üblicherweise sollte aber eine Einwirkungszeit von 10 bis 60 Minuten ausreichend sein, um eine gute Färbung zu erzielen.Usually, however, an exposure time of 10 to 60 minutes should be sufficient to achieve a good color.
Die folgenden Beispiele sollen den Gegenstand der Erfindung näher beschreiben: The following examples are intended to describe the subject matter of the invention in more detail:

Jeweils 4 Teebeutel (20 g Pflanzenpulver) wurden mit 100 ml kochend¬ heißem Wasser in einem Becherglas Übergossen und 30 Minuten darin belassen. Dabei nahm das Wasser einen tiefen Farbton an.In each case 4 tea bags (20 g plant powder) were poured with 100 ml of boiling water in a beaker and left for 30 minutes. The water took on a deep color.
Dann wurden die Beutel aus der Lösung entfernt und die inzwischen auf 20°C abgekühlten Farbstofflösungen durch Zugabe von je 2,0 g Guarkernmehl und Verrühren in gebrauchsfertige Färbegele überführt.The bags were then removed from the solution and the dye solutions, which had meanwhile cooled to 20 ° C., were converted into ready-to-use coloring gels by adding 2.0 g of guar gum each time and stirring.
Die Färbegele wurden auf lichtblonde Haarsträhnchen mit Hilfe eines Färbepinsels aufgetragen. Nach einer Einwirkungszeit von 45 Minuten bei 20°C wurden die gefärbten Haarsträhnchen mit Wasser abgespült und getrocknet.The coloring gels were applied to light blonde hair with the help of a coloring brush. After an exposure time of 45 minutes at 20 ° C., the colored hair tresses were rinsed off with water and dried.
Dabei wurden die folgenden Färbungen erhalten: Rezeptur 1 kräftiges Rotorange Rezeptur 2 helles rötliches Braun Rezeptur 3 weizenblond Rezeptur 4 goldblond. The following colorations were obtained: Recipe 1 strong red-orange recipe 2 light reddish brown recipe 3 wheat blonde recipe 4 golden blonde.
