Abstract

Abstract Translated from German Flüssige Zubereitungen für Oxidationshaarfärbemittel, die Seifen, wasserlösliche kationische Polymere sowie Haarfarbstoff-Vorpro­dukte in einem wäßrigen oder wäßrig-alkoholischen Träger enthal­ten, können durch Amine der Struktur (C) in denen R¹ eine Alkyl-Gruppe mit 8 bis 22 C-Atomen, R² Wasserstoff oder eine Alkyl-Gruppe mit 8 bis 22 C-Atomen, R³ Wasserstoff und, falls r = q = 0 ist, eine Alkylgruppe mit 1 bis 4 Kohlenstoffatomen darstellt und m, n, o, p, q und r 0 oder Zahlen bis 6 sind, stabilisiert werden. Liquid preparations for oxidation hair colorants, which contain soaps, water-soluble cationic polymers and hair dye precursors in an aqueous or aqueous-alcoholic carrier, can be obtained by amines of structure (C) in which R¹ is an alkyl group with 8 to 22 carbon atoms, R² is hydrogen or an alkyl group with 8 to 22 carbon atoms, R³ represents hydrogen and, if r = q = 0, represents an alkyl group with 1 to 4 carbon atoms and m, n, o, p, q and r are 0 or numbers up to 6, be stabilized.
