Abstract:
A highly aqueous, heavy duty liquid laundry detergent composition which provides cost effective stain and soil removal performance when used in fabric laundering operations and which is of acceptable viscosity for use in home fabric laundering operations, said composition characterized by:(A) from 2% to 5% by weight of the composition of an anionic surfactant component which is free of aromatic-based anionic surfactants and which comprises alkyl polyethoxylate sulfates wherein the alkyl group contains from 8 to carbon atoms and polyethoxylate chain contains from 1 to 20 ethylene oxide moieties;(B) from 0.2% to 10% by weight of the composition of a nonionic surfactant component which is free of aromatic-based nonionic surfactants and which comprises:i) from 0.1% to 8% by weight of the composition of fatty alcohol ethoxylates of the formula R.sup.1 (OC.sub.2 H.sub.4).sub.n OH wherein R.sup.1 is a C.sub.8 -C.sub.16 alkyl group and n is from 1 to 16; andii) from 0.1% to 1.0% by weight of the composition of a surfactant amine having the formula: ##STR12##wherein R.sub.1 is a C.sub.6 -C.sub.12 alkyl group n is from 2 to 4, X is a bridging group which is selected from NH, CONH, COO, or O or X can be absent; and R.sub.3 and R.sub.4 are individually selected from H, C.sub.1 -C.sub.4 alkyl, or (CH.sub.2 --CH.sub.2 --O(R.sub.5)) wherein R.sub.5 is H or methyl;(C) from 0.1% to 3% by weight of the composition of a viscosity-enhancing agent component selected from the group consisting of alkali metal and alkaline earth metal chlorides and formates, polyacrylic compositions having a molecular weight of from 500,000 to 1,000,000 and mixtures thereof; and(D) from 86% to 94% by weight of the composition of an aqueous, non-surface active liquid carrier which comprises no more than 3% by weight of the composition of liquids other than water.
