Abstract (en)
1. A liquid detergent containing a) from 5 to 18 % by weight of an alkyl polyglycol ether corresponding to the following formula see diagramm : EP0044003,P5,F1 in which R**1 is a straight-chain alkyl group and from 20 to 75 % by weight of R**2, based on the alcohol on which the alkyl polyglycol ether is based, is a C1 -C4 alkyl group and the remainder is hydrogen, the total number of carbon atoms in R**1 and R**2 amounting to between 11 and 15, and n has a value of from 5 to 9, n being selected in such a way that the ethylene oxide content of the alkyl polyglycol ether amounts to between 50 and 65 % by weight, b) from 5 to 18 % by weight of an alkyl polyglycol ether corresponding to formula I, in which R**1 is a straight-chain alkyl group and R**2 is either hydrogen of from 20 to 75 % by weight of R**2, based on the alcohol on which the alkyl polyglycol ether is based, is a C1 -C4 alkyl group and the remainder is hydrogen, the total number of carbon atoms in R**1 and R**2 amounting to between 6 and 10, and n has a value of from 3 to 8, n being selected in such a way that the ethylene oxide content of the alkyl polyglycol ether amounts to between 55 and 70 % by weight, c) from 1 to 10 % by weight and preferably from 2 to 6 % by weight of a fabric-softening quaternary ammonium salt selected from the derivatives of ammonia and/or imidazoline preferably containing 2 long-chain aliphatic radicals in the molecule, the weight ratio of a) to b) preferably amounting to between 2:1 and 1:2, characterized in that it additionally contains d) up to 50 % by weight, based on the quantity of components a) and b), of a cationic starch ether containing ammonium groups, the quantitative ratio of c) to d) preferably amounting to between 3:1 and 1:3.
Abstract (de)
Das auf zwei verschiedenen nichtionischen Tensiden, von denen eines ein ethoxylierter Oxoalkohol (C13-C15) mit 55 - 65 Gew.-% Ethylenoxid und das andere ein ethoxylierter Oxo- oder Fettalkohol (C9-C12) mit 60 - 70 Gew.-% Ethyloxid ist, und wäscheweichmachenden quartären Ammoniumverbindungen basierende flüssige Waschmittel enthält kationische Stärkeether als Verfärbungsinhibitoren. Die eingesetzten kationischen Stärkeether werden durch Umsetzung von Stärke mit 2,3-Epoxypropyltrimethylammoniumsalzen erhalten. Verwendbar ist z.B. das Kartoffelstärkederivat Empresol N (Fa. Emsland-Stärke GmbH) mit tertiären und quartären N-Atomen und gleichmäßig über die ganze Stärkekette verteilter kationischer Ladung.
