Description
Reduktionsmittel, insbesondere Mercaptoverbindungen enthaltende Haarbehandlungsmittel Substituierte Mercaptane, wie z. B. die Thioglykotsäure, üben in alkalischen Medien schon bei gewöhnlichen bis schwach erhöhten Temperaturen, z. B. bei Körpertemperatur, eine reduzierende Wirkung auf die Haarsubstanz aus. Die aus Aden Cystinniolekiileti stammenden @Disulfidbindungen des Keratins werden dabei zum Teil zu Mercaptogruppen reduziert, so daß das Haar seine elastischen Eigenschaften verliert. Es kann in diesem Zustande verformt werden. Nach anschließender Reoxvdation der so gebildeten Mercaptogruppen des Keratinmolekiils durch oxydierende ,Mittel, wie z. B. Wasserstoffsuperoxyd, Bromat .u. dgl., gewinnt das Haar unter Beibehaltung der neuen Form seine elastischen Eigenschaften wieder. Man macht bekanntlich von dieser Eigenschaft der substituierten Mercaptane Gehrauch zur Herstellung von Dauerwellen in menschlichem Haar auf kaltem Wege.Reducing agents, in particular hair treatment agents containing mercapto compounds Substituted mercaptans, such as. B. thioglycotic acid, practice in alkaline media even at normal to slightly elevated temperatures, e.g. B. at body temperature, a reducing effect on the hair substance. Those from Aden Cystinniolekiileti @Disulphide bonds of the keratin originating from this sometimes become mercapto groups reduced so that the hair loses its elastic properties. It can be in be deformed in this state. After subsequent reoxidation of the so formed Mercapto groups of the keratin molecule by oxidizing agents, such as. B. hydrogen peroxide, Bromate u. Like., the hair gains its elasticity while maintaining the new shape Properties again. It is well known that this property is considered to be substituted Mercaptane Gehra also used to make permanent waves in human hair on cold Ways.
Die verwendeten Mercaptoverbindungen greifen neben den Haaren aber auch die Haut, mit der die Lösungen in Berührung kommen, an. Dieses hält sich im allgemelinen, zumal bei einer nur einmaligen Behandlung, in durchaus erträglichen Grenzen. Mitunter wird jedoch von empfindlichen Personen über Brennen und Jucken der Kopfhaut geklagt. Bei Personen, die des öfteren und längere Zeit mit den Lösungen der substituierten Mercaptaue in Berührung kommen, z. .B. bei Friseuren, kann jedoch die Einwirkung der Dauerwellflüssigkeiten so weit gehen, @daß die Haut der Hände, besonders an den empfindlichen Stellen zwischen den Fingern, weiter geschädigt ;wird, so daß selbst das Auftreten kleiner Wundstellen beobachtet wurde. 'Man hat bisher diese Schädigungen als unvermeidlich angesehen, obwohl sie natürlich die allgemeine Anwendung der Präparate beeinträchtigen. Auch bei anderen zur Behandlung der Haare dienenden Erzeugnissen, die Reduktionsmittel wie z. B. Hydroxylamin enthalten, sind ähnliche Beobachtungen gemacht worden.The mercapto compounds used work alongside the hair, however the skin with which the solutions come into contact. This stays in general lines, especially in the case of only a one-time treatment, in quite tolerable ones Limits. Sometimes, however, sensitive people experience burning and itching the scalp sued. For people who often and for a long time with the solutions the substituted mercaptaue come into contact, e.g. .B. at hairdressers, however the effect of the permanent wave fluids go so far that the skin of the hands, especially in the sensitive areas between the fingers, further damaged; so that even small sores are observed became. 'Up to now, this damage has been considered inevitable, although it is natural affect the general use of the preparations. Also with others for treatment hair products containing reducing agents such as B. contain hydroxylamine, similar observations have been made.
Es wurde nun gefunden, @daß .der Angriff von Reduktionsmitteln, insbesondere solchen, die .Mercaptogruppen enthalten, auf die Haut in weitem Maße unterbunden werden kann, wenn sie lösliche Aluminiumverbindungen enthalten. Soweit die Mercaptoverbindungen saure Gruppen, wie Carboxylgruppen oder Sulfonsäuregruppen enthalten, kann man die wasserlöslichen Aluminiumsalze dieser Verbindungen einsetzen. Fluch ein Zusatz von Aluminiumsalzen, wie Aluminiumsulfat. Aluminiumacetat u. dgl., genügt oft, zumal dann, wenn die Präparate @in schwach saurem Medium angewandt werden sollen. Im allgemeinen werden die Präparate zur Behandlung des menschlichen Haares aber in alkalischen Medien angewandt, und zwar _arbeitet man vorzugsweise bei einem PH von 9 bis 9,5, was man durch den -Zusatz schwacher alkalischer Stoffe, insbesondere .von Ammoniak, erreicht. Da durch das verwendete Alkali Aluminiumhydroxyd ausgefällt wird, :i,st es in solchen Fällen zweckmäßig, Aluminiumsalze anzuwenden, die auch in den benutzten alkalischen Medien löslich sind, z. B. Aluminiumtartrat. Den .gleichen Effekt kann man natürlich auch dadurch erreichen, daß man den benutzten Mischungen Verbindungen zugibt, die mit den Aluminiumsalzen Verbindungen geben, die in alkalischen Medien löslich sind, z. B. Weinsäure, Citronensäure oder andere organische Verbindungen mit Oxygruppen.It has now been found that the attack by reducing agents, in particular those that contain mercapto groups are largely suppressed on the skin if they contain soluble aluminum compounds. So much for the mercapto compounds acidic groups, such as carboxyl groups or sulfonic acid groups, can be used use water-soluble aluminum salts of these compounds. Curse an addition of Aluminum salts such as aluminum sulfate. Aluminum acetate and the like are often sufficient, especially when the preparations are to be used in a weakly acidic medium. In general However, the preparations for the treatment of human hair are alkaline Media applied, namely _working preferably at a pH of 9 to 9.5, what can be achieved by adding weak alkaline substances, especially ammonia, achieved. Since aluminum hydroxide is precipitated by the alkali used: i, st In such cases it is advisable to use aluminum salts which are also used in the alkaline media are soluble, e.g. B. aluminum tartrate. Can have the same effect can of course also be achieved by adding compounds to the mixtures used admits, which give compounds with the aluminum salts in alkaline media are soluble, e.g. B. tartaric acid, citric acid or other organic compounds with oxy groups.
Der notwendige Gehalt an Aluminiumverbindungen beträgt im allgemeinen wenigstens aoo/o der reduzierenden Substanzen, kann aber auch ohne Beeinflussung der haarerweichenden Wirkung auf ein Vielfaches dieser !Menge gesteigert werden.The necessary content of aluminum compounds is generally at least aoo / o of the reducing substances, but can also be used without influencing them the hair-softening effect can be increased to a multiple of this! amount.
Die Herstellung der neuen Präparate ist sehr einfach. Man kann z. B. den Lösungen der reduzierenden Stoffe Lösungen der entsprechenden Aluminiumverbindungen zusetzen. Man kann aber auch die Präparate leicht @in feste Form bringen. So kann man z. B. feste Aluminiumsalze von Mercaptocarbon- oder Mercaptosulfonsäuren herstellen. Man kann aber auch so verfahren, daß man die festen Mercaptoverbindungen, wie die, Alkalisalze der Thioglykolsäure, der Mercaptobutansulfonsäure, mit festen Aluminiumsalzen, ,gegebenenfalls unter Zusatz lösender Stoffe, wie Sei,gnettesalz, mischt und erst bei der Anwendung aus diesen Salzmischungen die gewünschten Lösungen herstellt.The manufacture of the new preparations is very simple. You can z. B. the solutions of the reducing substances solutions of the corresponding aluminum compounds to add. But one can also easily bring the preparations into solid form. So can one z. B. produce solid aluminum salts of mercaptocarboxylic or mercaptosulfonic acids. But you can also proceed in such a way that the solid mercapto compounds, such as the Alkali salts of thioglycolic acid, mercaptobutanesulfonic acid, with solid aluminum salts, , if necessary with the addition of dissolving substances such as Sei, gnettesalz, mixes and first using these salt mixtures to produce the desired solutions.
Den Präparaten kann man wie üblich Duftstoffe, Netzmittel, Farbstoffe
u. dgl. zumischen oder den wäßrigen Lösungen Lösungsmittel, wie Alkohole,
