Description
Verfahren zum Erweichen von geformten, schwefelhaltigen Skleroproteinen, wie z. B. von Haaren. Die Skleroproteine haben im Tierreich die Rolle von Gerüststoffen und sind in Nasser und Salzlösungen unlöslich. Man rechnet zu ihnen vor allem das Keratin, d. h. die Substanz der Haare, Federn, Nägel usw., ferner das Gerüsteiweiss der Sehnen und anderer elasti scher Gewebe, das Kollagen der Knochen, Knorpel, Bindegewebe usw.
Es wurde nun gefunden, dass man derartige geformte Skleroproteine, soweit sie schwefel haltig sind, dadurch erweichen kann, dass man sie mit Lösungen von Thioharnstoffen behan delt. Der Thioharnstoff kann gegebenenfalls auch an einer Aminogruppe substituiert sein. Geeignete Substituenten sind z. B. die 3llethyl- gruppe, die Äthylgruppe, die Propylgruppe u. a. m. Jedoch dürfen diese Gruppen die Verbindungen nicht .unlöslich machen.
Auch sollen sie, da das wirksame Prinzip der Ver bindungen die -S-Gruppe ist, kein zu hohes Molekulargewicht aufweisen, da sonst der Schwefelgehalt der Verbindungen zu gering wird.
Je nach den Temperatur- und Konzentra tionsbedingungen, den p..-Verhältnissen und dem angestrebten Zweck muss die Behandlung der geformten, seliwefelhaltigen Skleroproteine kürzere oder längere Zeit erfolgen. Es ist im all gemeinen nicht notwendig, hohe Temperaturen anzuwenden. Z. B. erweichen Haare bereits bei Temperaturen von 25-40o in durchaus trag baren Zeiträumen, z. B, bei einer Konzen- tration der Lösungen von etwa 5-15'/o in 1/z Stunde bis 2 Stunden.
Durch Einwirkung der Thioharnstoffe wer den in den Skleroproteinen vorhandene disul- fidartige Schwefelbindungen unter Bildung von -SH-Gruppen aufgespalten. Diese Wir kung wird sehr gefördert, wenn die Lösungen ausserdem alkalisch reagierende Stoffe enthal ten.
Es ist daher vorteilhaft, den Lösungen alkalisch reagierende Salze, wie Trinatrium- phosphat, Soda, Borax, Metaborat oder Ätzal- kalien, wie Ätznatron, Ammoniak und dgl. zu zusetzen. Die Thioharristoffe werden im all gemeinen in wässrigen Lösungen angewandt; jedoch- ist es mitunter auch angebracht, Alko hole, wie Äthyl-, Propylalkohol oder andere wasserlösliche Lösungsmittel mit zu verwenden.
Die Produkte können in fester Form oder als gebrauchsfertige Lösungen in den Handel gebracht werden. Ausser den erwähnten alka lischen Zusatzstoffen können die Lösungen auch noch andere Zusätze enthalten, wie z. B. Duftstoffe, Netz- und Emulgiermittel usw. Man kann auch weitere Reduktionsmittel, wie Hydroxylamin, zufügen.
Die Wirkung der Thioharnstoff e kann durch eine nachträgliche Behandlung mit oxydieren den Mitteln wieder aufgehoben werden. Solche oxydierenden Mittel sind z. B. V@Tasserstoffsuper- oxyd und seine Derivate, wie Perverbindungen, und Anlagerungsverbindungen an Harnstoff und dgl. mehr, ferner Bromate und dgl. Durch diese Reoxydation werden wieder Disulfidbindungen hergestellt.
Man kann die gebildeten -SH-Gruppen aber auch mit andern reaktionsfähigen Verbindungen umsetzen, z. B. mit alkylierenden Mitteln.
Das Verfahren gemäss vorliegender Erfin dung lässt sich auf vielfache Weise anwenden. So kann man z. B. den mit den Thioharn- Stoffen behandelten, geformten schwefelhaltigen Skleroproteinen, die dadurch ihre Elastizität verloren haben, eine andere Form geben und danach die erweichende Wirkung durch Reoxy- dation wieder aufheben. Die Skleroproteine bleiben dann unter Wiedergewinnung ihrer elastischen Eigenschaften in dem verformten Zustand. In dieser Weise lässt sich das Ver fahren z.
B. zur Herstellung von Dauerwellen in lebendem oder totem Haar auf kaltem Wege, oder auch zum Glätten von naturkrausem Haar, z. B. bei Negern, ausnutzen. Eine andere An- wendungsmöglichkeit ist das Entfernen von Haaren und dergleichen.
Nach der Behandlung wird im allgemeinen mit - Wasser gewaschen, um die wasserlös lichen Verbindungen, wie überschüssige Reak tionsteilnehmer, Zusätze und dergleichen zu entfernen. Beispiel: 15 Gewichtsteile Thioharnstoff werden unter Zusatz von 3 g Ätznatron und 4 g Te- tranatriumpyrophosphat in 100 cm3 Wasser aufgelöst.
Der Lösung werden 0,2g Alkyl- benzolsulfonat zugesetzt. (p" der Lösung 11,8.) Zur Anfertigung einer kalten Dauerwelle wird das lebende menschliche Haar auf etwa 50-60 Holzwickel von Bleistiftstärke aufge wickelt und danach mit der vorgenannten Lösung durchfeuchtet. Zur Stauung der Kör perwärme wird um das Haar ein trockenes Tuch gelegt. Nach etwa 30-40 Minuten wird die Erweichung des Keratins durch mehr maliges Behandeln des Haares mit verdünnter Wasserstoffsuperoxydlösung aufgehoben und dadurch das Haar in der Wellenform fixiert.
Nach einer gründlichen Kopfwäsche nach vor herigem Entfernen der Holzwickel ist das Haar bleibend in Form einer Krause gewellt.
Process for softening formed, sulfur-containing scleroproteins, such as e.g. B. of hair. In the animal kingdom, the scleroproteins play the role of builders and are insoluble in water and salt solutions. They include mainly keratin, i. H. the substance of the hair, feathers, nails, etc., also the structural protein of the tendons and other elastic tissues, the collagen of the bones, cartilage, connective tissue, etc.
It has now been found that such shaped scleroproteins, insofar as they contain sulfur, can be softened by treating them with solutions of thioureas. The thiourea can optionally also be substituted on an amino group. Suitable substituents are e.g. B. the 3llethyl- group, the ethyl group, the propyl group u. a. m. However, these groups must not make the compounds .insoluble.
Also, since the effective principle of the compounds is the -S group, they should not have a molecular weight that is too high, otherwise the sulfur content of the compounds will be too low.
Depending on the temperature and concentration conditions, the p .. conditions and the intended purpose, the treatment of the formed, seliulfur-containing scleroproteins must be carried out for a shorter or longer period of time. It is generally not necessary to use high temperatures. For example, hair already softens at temperatures of 25-40o in quite acceptable periods of time, e.g. B, with a concentration of the solutions of about 5-15% in 1/2 hour to 2 hours.
The action of the thioureas breaks down the disulfide-like sulfur bonds present in the scleroproteins with the formation of -SH groups. This effect is greatly enhanced if the solutions also contain substances with an alkaline reaction.
It is therefore advantageous to add alkaline salts, such as trisodium phosphate, soda, borax, metaborate, or caustic alkalis, such as caustic soda, ammonia and the like, to the solutions. The thioharristics are generally used in aqueous solutions; However, it is sometimes also appropriate to use alcohols such as ethyl, propyl alcohol or other water-soluble solvents.
The products can be marketed in solid form or as ready-to-use solutions. In addition to the alka-metallic additives mentioned, the solutions can also contain other additives, such as. B. fragrances, wetting and emulsifying agents, etc. You can also add other reducing agents, such as hydroxylamine.
The effect of the thioureas can be reversed by subsequent treatment with oxidizing agents. Such oxidizing agents are e.g. B. V @ hydrogen superoxide and its derivatives, such as per compounds, and addition compounds to urea and the like. Furthermore, bromates and the like. This reoxidation re-establishes disulphide bonds.
You can also implement the formed -SH groups with other reactive compounds, for. B. with alkylating agents.
The method according to the present invention can be used in many ways. So you can z. For example, the formed sulfur-containing scleroproteins treated with the thioures, which have lost their elasticity as a result, are given a different shape and then reverse the softening effect by reoxidation. The scleroproteins then remain in the deformed state while regaining their elastic properties. In this way, the process can go z.
B. for the production of permanent waves in living or dead hair by cold means, or for straightening naturally frizzy hair, z. B. in negroes. Another possible application is removing hair and the like.
After the treatment, washing is generally carried out with - water in order to remove the water-soluble compounds, such as excess reactants, additives and the like. Example: 15 parts by weight of thiourea are dissolved in 100 cm3 of water with the addition of 3 g of caustic soda and 4 g of tetrasodium pyrophosphate.
0.2 g of alkyl benzenesulfonate are added to the solution. (p "of the solution 11.8.) To make a cold permanent wave, the living human hair is wound on about 50-60 wooden coils of pencil thickness and then moistened with the aforementioned solution. A dry cloth is placed around the hair to accumulate body heat After about 30-40 minutes, the softening of the keratin is reversed by treating the hair several times with diluted hydrogen peroxide solution and thereby fixing the hair in the wave shape.
After a thorough head wash after removing the wooden wrap, the hair is permanently wavy in the form of a frizze.
