Abstract:
A microemulsion cleaning composition comprising:(a) 0.1 to 10 wt. % of an ethoxylated/propoxylated nonionic surfactant;(b) 0.1 wt. % to 20 wt. % of an anionic surfactant selected from the group consisting of alkyl benzene sulfonated surfactants, alkene sulfonated surfactants and sulfated surfactants;(c) 0 to 10 wt. % of a mixture of: ##STR10##wherein w equals one, and B is selected from the group consisting of hydrogen and a group represented by: ##STR11##wherein R is selected from the group consisting of alkyl group having 6 to 22 carbon atoms, and alkenyl groups having 6 to 22 carbon atoms, wherein at least one of the B groups is represented by said ##STR12##R' is selected from the group consisting of hydrogen and methyl groups; x, y and z have a value between 0 and 60, provided that (x+y+z) equals 2 to 100, wherein in Formula (I) the weight ratio of monoester/diester/triester is 40 to 90/5 to 35/1 to 20, wherein the weight ratio of Formula (I) and Formula (II) is a value between 3 and 0.02;(d) 0.1% to 15% of a glycol ether cosurfactant;(e) 0.05% to 2% of a fatty acid;(f) 0.1 to 10 wt. % of a water insoluble hydrocarbon, essential oil or a perfume; and(g) the balance being water, wherein the composition does not contain a grease release agent characterized by the formula: ##STR13##wherein R.sub.1 is a methyl group and R.sub.2, R.sub.3 and R.sub.4 are independently selected from the group consisting of methyl, ethyl, and CH.sub.2 CH.sub.2 Y, wherein Y is selected from the group consisting of Cl, Br, CO.sub.2 H, (CH.sub.2 O).sub.n OH wherein n=1 to 10, OH, CH.sub.2 CH.sub.9 OH and x is selected from the group consisting of Cl, Br, methosulfate ##STR14##and HCO.sub.3.sup.- and the composition does not contain a grease release agent which is an ethoxylated maleic anhydride-alpha-olefin copolymer having a comblike structure with both hydrophobic and hydrophilic chains and is depicted by the formula: ##STR15##wherein n is about 5 to about 14, x is about 7 to 19, and y is of such a value as to provide a molecular weight about 10,000 to about 30,000.
