Abstract
A detergent composition containing a semi-polar nonionic detergent and an alkaline earth metal salt of an anionic detergent in a ratio of from 1:100 to 1:2. The composition is especially useful for the removal of greasy soils.
Claims20
A detergent composition especially effective in removing greasy soils consisting essentially of a mixture of:
- (a) a water-soluble amine oxide 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) a magnesium 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, (4) olefin sulfonates having 8 to 22 carbon atoms, (5) alkyl ether sulfates having 8 to 22 carbon atoms in the alkyl group and 1 to 30 ethylene oxide units, (6) alkyl glyceryl ether sulfonates having 8 to 22 carbon atoms in the alkyl group and (7) mixtures thereof in a weight ratio of amide oxide to anionic detergent of from 1:100 to 1:2;
- and
- (c) the balance selected from the group consisting of water, mixtures of water and C.sub.1 -C.sub.5 alkanols, and inert filler salts.

A liquid detergent composition consisting essentially of:
- (a) from 2% to 6% of a water-soluble amine oxide having one alkyl moiety of 8 to 16 carbon atoms and two alkyl moieties of 1 to 3 carbon atoms;
- (b) from 10% to 30c/0 of a magnesium alkyl sulfate having 12 to 16 carbon atoms;
- (c) from 0% to 20% of a magnesium alkyl ether sulfate derived from an alcohol having 12 to 16 carbon atoms ethoxylated with 1 to 12 moles of ethylene oxide;
- (d) from 0% to 7% mono-, di-, or triethanolamine, or mixtures thereof;
- (e) from 0% to 15% mono-, di-, or triethanolammonium sulfate, or mixtures thereof;
- and
- (f) the balance water or mixtures of water and C.sub.1 -C.sub.5 alkanol.
