  • 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.
