Abstract

Low foaming, liquid, aqueous washing agent concentrate comprising PA0 (a) 5 to 12 weight % of a linear sodium alkyl benzene sulfonate with 10-13 carbon atoms in the alkyl chain and/or of a linear secondary sodium alkane sulfonate with 14-18 carbon atoms: PA0 (b) 2 to 6 weight % of a linear sodium alkyl polyglycol ether sulfate with 10-16 carbon atoms in the alkyl chain and 1-3 ethylene glycol ether groups; PA0 (c) 2 to 6 weight % of a sodium or potassium soap of mainly saturated fatty acids with 12-18 carbon atoms, 50-90 weight % of which have 16-18 carbon atoms; PA0 (d) 15 to 28 weight % of a mixture of ethoxylated alcohols, consisting of (i) 30-50 weight % of linear primary ethoxylated alcohols with 16-18 carbon atoms and 8-12 glycol ether groups and (ii) 30-50 weight % of linear primary ethoxylated alcohols with 16-18 carbon atoms and 3-7 glycol ether groups, both of said ethoxylated alcohols having a ratio of saturated to mono-unsaturated hydrocarbon residues of 1:4 to 4:1, and (iii) 10-30 weight % of linear and/or 2-methyl substituted primary saturated ethoxylated alcohols with 10-15 carbon atoms and 4-9 glycol ether groups; PA0 (e) 2 to 7 weight % of a fatty acid diethanolami…
