Abstract (en)

[origin: US4832863A] A detergent composition which is distinguished by high detergency with respect to soil containing mineral oil and by low foaming both in the wash cycle and in the rinse cycle of automatic washing machines comprising (A) from 0.5 to 2% by weight C9-C13 alkyl benezenesulfonate, (B) from 10 to 15% by weight of a fatty alcohol or oxo alcohol containing 2 to 4 ethylene oxide groups, (C) from 4 to 8% by weight of a fatty alcohol or oxo alcohol containing 6 to 8 ethylene oxide groups, the alcohols in (C) and (D) containing 12 to 15 carbon atoms, (E) from 0 to 2% by weight of a saturated or mono-unsaturated C16-C18 alcohol containing 3 to 7 ethylene oxide groups, (E) from 5 to 20% by weight finely-divided crystalline zeolite, (F) from 40 to 60% by weight anhydrous sodium carbonate, (G) from 2 to 7% by weight sodium silicate and (H) from 0.5 to 2% by weight of a polymeric soil redeposition inhibitor.
