Description
Mittel zur Haarverformung im sauren Medium Zusatz zur Patentanmeldung C 11091 IVa/30h (Auslegeschrift1009 76S) In der Hauptpatentanmeldung C 11091 IVa/30h wird ein Mittel zur Haarverformung im sauren Medium beschrieben, welches aus einer wäßrigen Lösung eines Sulfhydrylcarbonsäureesters besteht, der mindestens eine hydrophile Gruppe enthält, wobei diese Lösung auf einen p-Wert zwischen 4,0 und 7,0 eingestellt ist. Agent for shaping hair in an acidic medium. Addition to patent application C 11091 IVa / 30h (Auslegeschrift1009 76S) In the main patent application C 11091 IVa / 30h a means for hair shaping in the acidic medium is described, which consists of a aqueous solution of a sulfhydryl carboxylic acid ester, which has at least one hydrophilic Group, this solution being adjusted to a p-value between 4.0 and 7.0 is.
Überraschenderweise wurde weiterhin durch zahlreiche Versuche gefunden, daß die verformende Wirkung der Merkaptocarbonsäuremonoester im gesamten sauren Bereich weitgehend vom pH-Wert unabhängig ist. Es ist also ohne wesentliche Beeinträchtigung der haarverformenden Wirkung möglich, den Merkaptocarbonsäuremonoester im sauren pH-Bereich von etwa 1 an nach höheren Werten mit Erfolg anzuwenden. Die Versuche ergaben ferner, daß selbst nach Zugabe starker Säuren, z. B. bei einem pH-Wert von etwa 1, die Haarverformung durchaus befriedigend verläuft. Man wird natürlich aus Gründen physiologischer Verträglichkeit und Unbedenklichkeit des Präparates selten einen so niedrigen pH-Wert wählen, sondern sich mit einem etwas höheren p-Wert, z. B. von 2 an, begnügen. Surprisingly, it was also found through numerous experiments that the deforming effect of the mercaptocarboxylic acid monoester throughout the acidic Range is largely independent of the pH value. So it is without any significant impairment the hair-shaping effect possible, the mercaptocarboxylic acid monoester in the acidic Use the pH range from about 1 to higher values with success. The trials also showed that even after the addition of strong acids, e.g. B. at a pH of about 1, the hair deformation is quite satisfactory. You will of course be out Rarely for reasons of physiological tolerance and harmlessness of the preparation choose such a low pH value, but with a slightly higher p-value, z. B. from 2 on, be satisfied.
Man kann bei der Herstellung des erfindungsgemäßen Mittels von einem völlig säurefreien Monoester einer Merkaptocarbonsäure ausgehen, dessen Lösung durch Zufügen von Säuren oder Salzen auf einen beliebigen p-Wert zwischen 1 und 7, und zwar aus physiologischen Gründen z. B. zwischen 2 und 7, eingestellt wird.You can in the preparation of the agent according to the invention from one run out completely acid-free monoester of a mercaptocarboxylic acid, dissolve it through Adding acids or salts to any p-value between 1 and 7, and although for physiological reasons z. B. between 2 and 7 is set.
