Detergent composition containing semi-polar nonionic detergent alkaline earth metal anionic detergent and amino alkylbetaine detergent

A detergent composition especially effective in removing greasy soils wherein the organic detergent portion of said composition consists essentially of a mixture of:

• (a) from about 1/2% to about 6% of a semi-polar organic nonionic detergent comprising water-soluble amine oxides having one alkyl or hydroxy alkyl moiety of 8 to 28 carbon atoms and two alkyl moieties selected from the group consisting of alkyl groups and hydroxy alkyl groups of 1 to 3 carbon atoms;
• (b) from about 10% to about 50% of an alkaline earth metal salt of an anionic detergent selected from the group consisting of (1) linear alkyl benzene sulfonates having 9 to 15 carbon atoms in the alkyl group, (2) alkyl sulfates having 8 to 22 carbon atoms, (3) alkyl ether sulfates having 8 to 22 carbon atoms in the alkyl group and 1 to 30 ethylene oxide units, and (4) mixtures thereof;
• (c) from about 1/2% to about 6% of an acylamidoalkylbetaine of the formula:
• ##STR2## wherein R is an alkyl group containing from about 7 to about 21 carbon atoms, R.sup.1 is hydrogen or an alkyl group containing from 1 to about 6 carbon atoms, R.sup.2 is an alkylene group containing from 1 to about 10 carbon atoms, each R.sup.3 is an alkyl or hydroxy group containing from 1 to about 6 carbon atoms or an ethoxylated hydroxy group containing from about 1 to about 10 ethylene oxide units, and R.sup.4 is an alkylene group containing from 1 to about 6 carbon atoms.
