Abstract (en)

[origin: WO2005118767A1] The present invention refers to a paste-like, thixotropic, alkaline detergent or cleaning concentrate comprising a) at least one first component selected from one or more compounds represented by the general formula (I): R<1>-(OC2H4)n-(OC3H6)m-OH wherein R<1> represents an unbranched or branched alkyl or alkenyl group having 4 to 8, preferably 5 to 7, carbon atoms, and wherein the sum of the average degree of ethoxylation n and propoxylation m ranges from 1 to 9, preferably from 3 to 7, with one of n and m optionally being 0, and b) at least one second component selected from one or more compounds repre­sented by the general formula (II): R<2>-(OC2H4)0-(OC3H6)p-OH wherein R<2>represents an unbranched or branched alkyl or alkenyl group having 9 to 22, preferably 10 to 16, carbon atoms, and wherein the sum of the average degree of ethoxylation o and propoxylation p is between 1 and 9, preferably between 3 and 7, with one of o or p optionally being 0, the cleaning concentrate exhibiting at 25°C a viscosity of from 80 000 mPas to 250 000 mPas at 5 revolutions per minute and a viscosity of from 20 000 mPas to 80 000 mPas at 50 revolutions per minute, each measured using a Brookfield rotational viscometer (spindle no. 7) under otherwise identical conditions. Moreover, it deals with a stable parent lye containing said concentrate and a method for washing textiles comprising one step in which a parent lye is prepared by diluting said concentrate and in 30 which the waste water accumulated during the whole washing process or parts thereof may be purified using a membrane filtration unit.
