Description

Verfahren zur Herstellung eines alkalisch bis neutral reagierenden Haarfärbemittels aus schwerlöslichen aromatischen Diaminen für das lebende menschliche Haar Eine Reihe der als Haarfärbemittel für das menschliche lebende Haar bekannten aromatischen Diamine besitzt nur eine geringe Wasserlöslichkeit. Um sie in wäßriger Lösung zu halten, ist ein beträchtlicher Zusatz einwertiger Alkohole oder von Aceton erforderlich. So ist z. B. das p-Amidodiphenylamin nur in 50°lOiger alkoholischer Lösung löslich.Process for the production of an alkaline to neutral reaction Hair dye made from sparingly soluble aromatic diamines for the living human Hair A range of those known as hair dyes for human living hair aromatic diamine has only a low solubility in water. To them in more watery Holding solution is a substantial addition of monohydric alcohols or acetone necessary. So is z. B. the p-amidodiphenylamine only in 50 ° lOiger alcoholic Solution soluble.

Wird diese mit Wasser verdünnt, so fällt die Base wieder aus. Ähnlich verhält es sich mit dem pp'-Diamidodiphenylamin und anderen Basen. Es war daher nicht möglich, wasserreiche, haltbare Lösungen dieser Basen herzustellen.If this is diluted with water, the base precipitates out again. Similar it is the same with pp'-diamidodiphenylamine and other bases. It was therefore not possible to produce water-rich, durable solutions of these bases.

Es wurde nun gefunden, daß man solche haltbane wäßrige Lösungen schwerlöslicher aromatischer Diamine erzielen kann, wenn man ihnen Kondensationsprodukte aus abgebautem Eiweiß vom Typ Lysalbin bzw. Protalginsäure mit höheren Fettsäuren in Form ihrer wasserlöslichen Alkalisalze allein oder im Gemisch mit anderen organischen Lösungsmitteln zusetzt. It has now been found that such permanent aqueous solutions are more sparingly soluble aromatic diamines can be obtained if they are degraded condensation products Protein of the lysalbine or protalgic acid type with higher fatty acids in their form water-soluble alkali salts alone or in a mixture with other organic solvents clogs.

Beispiel 6 g pp'-Diamidodiphenyla'min werden in IOO ccm Acetin (wasserlöslich) gelöst, 50 ccm Kondensationsprodukt aus abgebautem Eiweiß vom Typ Lysalbin- bzw. Protalbinsäure mit höheren Fettsäuren in Form ihrer Wasser löslichen Alkalisalze und darauf IOO ccm destilliertes Wasser zugesetzt. Example 6 g of pp'-diamidodiphenyla'min are dissolved in 100 ccm of acetin (water-soluble) dissolved, 50 ccm condensation product from degraded protein of the lysalbine or Protalbic acid with higher fatty acids in the form of their water-soluble alkali salts and then 100 cc of distilled water was added.

Die so erhaltene Lösung läßt sich beliebig mit Wasser verdünnen, ohne daß die Base wieder ausfällt. The solution obtained in this way can be diluted with water as desired, without the base precipitating again.
