Description
Verfahren zur Änderung der Struktur von schwefelhaltigen Skleroproteinen Die Skieroproteine haben im Tierreich die Rolle von Geräststoffen und sind in Wasser und Salzlösungen unlöslich. Man rechnet zu ihnen vor allem das Keratin, d. h. die Substanz der Haare, Wolle, Federn, Nägel usw., ferner das Gerüsteiweiß der Sehnen und anderer elastischer Gewebe, Seidenfibroin, das Kollagen der Knochen, Knorpel, Bindegewebe usw. Es wurde nun, gefunden, daß man derartige Skleroproteine, soweit sie schwefelhaltig sind, dadurch in ihrer Struktur verändern kann, daß man sie mit Lösungen von Xanthogenaten behandelt. Geeignete Verbindungen sind z. B. die Natrium- oder Kaliumsalze der Methylxanthogensäure, der Äthylxanthogensäure, der P ropylxanthogensäure u. a. m.Process for changing the structure of sulfur-containing scleroproteins the In the animal kingdom, skieroproteins play the role of basic substances and are found in water and saline solutions insoluble. They include mainly keratin, i. H. the Substance of hair, wool, feathers, nails, etc., also the skeletal protein of the tendons and other elastic tissues, silk fibroin, the collagen of bones, cartilage, Connective tissue, etc. It has now been found that such scleroproteins can be used as far as They contain sulfur and can change their structure by using them with Treated solutions of xanthates. Suitable compounds are e.g. B. the sodium or potassium salts of methylxanthogenic acid, ethylxanthogenic acid, propylxanthogenic acid i.a. m.
Die Xanthogenate werden im allgemeinen in wäßrigen Lösungen angewandt; jedoch ist es mitunter auch angebracht, alkohole, wie Methyl-, Äthyl-, Propylalkohol od. dgl. Lösungsmittel, mitzuverwenden. The xanthates are generally used in aqueous solutions; however, it is sometimes also appropriate to use alcohols such as methyl, ethyl or propyl alcohol Od. Like. Solvents to be used.
Je nach den Temperatur- und Konzentrationsbedingungen, den pH-Verhältnissen und dem angestrebten Zweck muß die Behandlung der schwefelhaltigen Skleroproteine kürzere oder längere Zeit erfolgen. Es ist im allgemeinen nicht notwendig, hohe Temperaturen anzuwenden. Zum Beispiel erweichen Haare bereits bei Temperaturen von 25 bis 400 in durchaus tragbaren Zeiträumen; z. B. bei einer Konzentration der Lösungen von etwa 5 bis Ig'O/o in 1/2 bis 2 Stunden. Depending on the temperature and concentration conditions, the pH conditions and the intended purpose must be the treatment of sulfur-containing scleroproteins take place for a shorter or longer period of time. It is generally not necessary to be high Temperatures to apply. For example, hair already soften at temperatures of 25 to 400 within a reasonable period of time; z. B. at a concentration of the solutions from about 5 to Ig'O / o in 1/2 to 2 hours.
Durch Einwirkung der Xanthogenate werden in denSkleroproteinen vorhandene disulfidartigeSchwefelbindungen unter Bildung von -SH-Gruppen aufgespalten. Diese Wirkung wird im allgemeinen gefördert, werm die Lösungen außerdem alkalisch reagierende Stoffe enthalten. Es ist daher vorteilhaft, den Lösungen alkalisch reagierende Salze, wie Trinatriumphosphat, Soda, Borax, Metaborat, oder Ätzalkalien, wie Ätznatron, Ammoniak u. dgl., zuzusetzen. The action of xanthates becomes present in the scleroproteins disulfide-like sulfur bonds split to form -SH groups. These Effect will in general promoted, whom the solutions as well contain alkaline substances. It is therefore advantageous to make the solutions alkaline reactive salts such as trisodium phosphate, soda, borax, metaborate, or caustic alkalis, such as caustic soda, ammonia and the like. To be added.
Außer den erwähnten alkalischen Zusatzstoffen können die Erzeugnisse auch noch andere Zusätze enthalten, wie z. B. Duftstoffe, Netz- und Emulgiermittel usiw. Man kann auch Reduktionsmittel, wie Hydroxylamin, zufügen, um ein;e vorzeitige Oxydation der Mercaptogruppe durch den Luftsauerstoff zu verhindern. In addition to the alkaline additives mentioned, the products also contain other additives, such as B. Fragrances, wetting agents and emulsifiers usiw. One can also add reducing agents, such as hydroxylamine, to prevent premature To prevent oxidation of the mercapto group by the oxygen in the air.
Die Wirkung der Xanthogenate kann durch eine nachträgliche Behandlung mit oxydierenden Mitteln wieder aufgehoben werden. Solche oxydierenden Mittel sind z. B. Wasserstoffsuperoxyd und seine Derivate, wie Perverbindungen und Anlagerungs verbindungen an Harnstoff u. dgl. m., ferner Bromate u. dgl. Durch diese Reoxydation werden wieder Disulfidbindungen hergestellt. Man kann die gebildeten-SH-Gruppen aber auch mit anderen reaktionsfähigen Verbindungen umsetzen, z. B. mit alkylierenden Mitteln, wie Alkylendibromiden, ferner mit Aldehyden, wie Formaldehyd oder Glyoxal. The effect of the xanthates can be achieved by subsequent treatment be lifted again with oxidizing agents. Such oxidizing agents are z. B. hydrogen peroxide and its derivatives, such as per compounds and addition compounds of urea and the like, also bromates and the like through this reoxidation disulfide bonds are established again. One can use the educated-SH groups but also implement with other reactive compounds, e.g. B. with alkylating Agents such as alkylenedibromides, also with aldehydes such as formaldehyde or glyoxal.
Die Erfindung läßt sich vielfach ausnutzen. So kann man z. B. die mit den Xanthogenaten behandelten schwefelhaltigen Skleroproteine, die dadurch ihre Elastizität verloren haben, verformen und danach die erweichende Wirkung durch Reoxydation oder Reaktion mit Aldehyden oder Alkylendihalogeniden wieder aufheben. Die Skleroproteine bleiben dann unter Wiedergewinnung ihrer elastischen Eigenschaften in dem verformten Zustand. Man kann sich dieser Eigenschaften z.B. zur Herstellung von Dauerwellen in lebende oder totem Haar auf kaltem Wege oder auch zum Glätten von naturkrausem Haar, z. B. bei Negern, bedienen. The invention can be exploited in many ways. So you can z. B. the sulfur-containing scleroproteins treated with the xanthates, which thereby reduce their Have lost elasticity, deform and then the softening effect through reoxidation or cancel the reaction with aldehydes or alkylene dihalides. The scleroproteins then remain in the deformed while regaining their elastic properties State. One can use these properties e.g. for the production of permanent waves in living or dead hair by cold means or for straightening naturally frizzy hair Hair, e.g. B. in negroes, use.
Eine andere Anwendungsmöglichkeit ist das Entfernen von Haaren u. dgl. Schließlich läßt sich durch Behandlung der erweichten Skleroproteine mit Aldehyden, wie Formaldehyd oder Alkylendihalogeniden, auch die Beständigkeit gegen chemische Einflüsse, z. B. die Alkalifestigkeit von Wolle, ganz erheblich steigern. Auch lassen sich in die behandelten Proteine vielfach Farbstoffe, Mottenschutzmittel u. dgl. besser einbauen.Another application is hair removal and the like. Like. Finally, by treating the softened scleroproteins with aldehydes, like formaldehyde or alkylene dihalides, also the resistance to chemical Influences, e.g. B. increase the alkali resistance of wool quite considerably. Let too The treated proteins often contain dyes, moth repellants and the like. better fit.
Nach der Behandlung wird im allgemeinen mit Wasser gewaschen, um die wasserlöslichen Verbindungen, wie überschüssige Reaktionsteilnehmer, Zusätze u. dgl.> zu entfernen. After the treatment, washing is generally carried out with water the water-soluble compounds, such as excess reactants, additives and the like> to remove.
Beispial 20 Gewichtsteile Natrium-äthylxantho,,oienat werden unter Zusatz von 5 com Ammoniak in 100 ccm Wasser aufgelöst. Der Lösung werden 0,2 g Alkylbenzolsulfonat zugesetzt. Beispial 20 parts by weight of sodium ethyl xanthate, oienate are under Addition of 5 com ammonia dissolved in 100 cc of water. 0.2 g of alkylbenzenesulfonate are added to the solution added.
Zur Anfertigung einer kalten Dauerwelle wird das lebende menschliche Haar auf etwa 50 bis 60 Holzwickel von Bleistiftstärke aufgewickelt und danach mit der vorgenannten Lösung durchfeuchtet. The living human is used to create a cold perm Hair wound on about 50 to 60 pencil-size wooden rolls and then with the aforementioned solution soaked.
Zur Stauung der Körperwärme wird um das Haar ein trockenes Tuch gelegt. Nach etwa 30 bis 40 Minuten wird die Erweichung des Keratins durch mehrmaliges Behandeln des Haares mit verdünnter Wasserstoffsuperoxydlösung aufgehoben und dadurch das Haar in der Wellenform fixiert.A dry cloth is placed around the hair to retain body heat. After about 30 to 40 minutes, the softening of the keratin is achieved through repeated treatments of the hair with diluted hydrogen peroxide solution and thereby the Hair fixed in the wave shape.
Nach einer gründlichen Kopfwäsche nach vorherigem Entfernen der Holzwickel ist das Haar bleibend in Form einer Krause gewellt.After a thorough head wash after removing the wooden wrap the hair is permanently wavy in the form of a frizze.
