Process for the preparation of said compositions.
Claims11
A light duty liquid detergent composition consisting essentially of
- a. from about 5% to about 35% of an anionic surfactant having the formula
- [R--(Y).sub.n --(O).sub.n SO.sub.2 M]
- r--(y).sub.n --(O).sub.n SO.sub.3 M
- wherein R is an alkyl group containing from 8 to about 24 carbon atoms which can be either straight or branched chain, saturated or unsaturated and attached either at the terminal position, a secondary position, or random attachment or mixtures thereof;
- Y is a group selected from the group consisting of (OC.sub.2 H.sub.4).sub.x wherein x is a number from 1 to 30;
- (O--CH.sub.2 --CHOH--CH.sub.2).sub.m wherein m is a number from 1 to 3;
- or a benzene ring;
- each n is either 0 or 1;
- and M is selected from the group consisting essentially of sodium;
- potassium;
- mono-, di-, or tri-alkanolammonium wherein the alkanol groups contain from 2 to 4 carbon atoms;
- mono-, di- or tri-alkylammonium wherein the alkyl groups contain from 2 to 4 carbon atoms;
- ammonium;
- magnesium;
- calcium;
- or mixtures thereof;
- b. from 0% to about 15% of a suds boosting ingredient selected from the group consisting of amine oxide surfactants and amide surfactants;
- c. from 0.5% to about 10% of a detergency boosting ingredient selected from the group consisting of compounds having the formula ##STR9## wherein R.sup.10 is an alkyl group containing from about 14 to about 20 carbon atoms, wherein R.sup.11 is an alkylene group containing 2 or 3 carbon atoms, wherein n.sup.2 is 0 or 1, wherein n.sup.3 is a number from 0 to about 20, wherein n.sup.4 is 0 or 1, wherein M is a cation selected from the group consisting of hydrogen;
- sodium;
- potassium;
- ammonium;
- mono-, di-, and tri-alkanolammonium;
- mono-, di-, and tri-, alkylammonium;
- magnesium;
- calcium;
- and mixtures thereof, R.sup.10 being a random alkyl group when n.sup.2, n.sup.3 and n.sup.4 are 0;
- d. from 0% to heavy metal chelating amounts of citric acid salt;
- and,
- e. water, the pH of the composition being above 7 and less than about 10 and said composition being free of effective amounts of detergency builders.
