  • Patent number: 4153570
    Abstract: Low foaming, liquid, aqueous washing agent concentrate comprising(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:(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;(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;(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

  • Patent number: 3931033
    Abstract: Liquid foam-regulated washing and cleansing agent compositions containing non-ionic surface-active compounds and organic water-miscible solvents of the following composition:A. 30 to 60 percent by weight of a combination of two ethoxylated alcohols having from 12 to 20 carbon atoms,B. 2 to 6 percent by weight of an alkali metal soap of fatty acids with substantially 12 to 18 carbon atoms,C. 0.1 to 1 percent by weight of a water-soluble organic sequestering agent for heavy metal ions,D. 20 to 35 percent by weight of a water-miscible organic solvent combination of an aliphatic ether alcohol with 5 to 8 carbon atoms and an alkanediol with 2 to 6 carbon atoms, optionally with up to 3 percent by weight of ethanol or isopropyl alcohol, andE. at least 8 percent by weight up to the balance of 100 percent by weight, of water; as well as the method of washing solid articles utilizing the said compositions.
