Abstract
Abstract Translated from German Haarfärbemittel auf Basis von Oxidationsfarbstoffen enthalten neben üblichen Kupplersubstanzen als Entwicklerkomponente hydroxyalkylierte Alkylamino-p-phenylendiamine der allgemeinen Formel (1) oder deren Salze. n = 2 - 4; R 1 , R 2 = H, Mono- oder Polyhydroxyalkyl-(C 2-6 ), wobei mindestens einer der Reste R 1 , R 2 ein Mono- oder Polyhydroxyalkylrest ist. Hair colorants based on oxidation dyes contain, in addition to conventional coupler substances, hydroxyalkylated alkylamino-p-phenylenediamines of the general formula (1) or salts thereof as developer components. n = 2-4; R 1 , R 2 = H, mono- or polyhydroxyalkyl- (C 2-6 ), at least one of the radicals R 1 , R 2 being a mono- or polyhydroxyalkyl radical. Eine bevorzugte Verbindung ist N-(p-Aminophenyl)-N',N'-bis-(ß-hydroxyethyl)-1,3-diaminopropan. A preferred compound is N- (p-aminophenyl) -N ', N'-bis- (β-hydroxyethyl) -1,3-diaminopropane. Die Anwendungskonzentration der Entwickler/Kuppler-Kombination beträgt 0,2-5 (1-3) Gew.-%. The application concentration of the developer / coupler combination is 0.2-5 (1-3)% by weight.
