Claims
- 1. A homogeneous aqueous liquid laundering and cleaning detergent composition, essentially free from inorganic builder salt consisting essentially of:
- (a) from about 20 to about 40 wt. % of a mixture of nonionic surfactants of the formula:
- RO--[CH.sub.2 --CH(CH.sub.3)--O].sub.m --(CH.sub.2 --CH.sub.2 --O).sub.n --H (I)
- wherein R is a C.sub.10 -C.sub.20 aliphatic hydrocarbon group which is linear or methylated in the 2-position and can be saturated or unsaturated, or R represents a mixture of such groups; m is a number from 1 to 5; n is a number from 3 to 20; n>m; and wherein the mixture of nonionic surfactants is composed of the following components:
- (i) from about 5 to about 9 parts by weight of at least one compound of the above Formula I wherein n=3 to 9,
- (ii) from about 1 to about 5 parts by weight of at least one compound of the above Formula I wherein n=10 to 20, and
- (iii) from 0 to about 6 parts by weight of a compound of the above Formula I wherein m=1 to 3 and n=9 to 11;
- (b) from about 2 to about 25 wt. % based on fatty acid of at least one sodium, potassium monoalkanolamine, dialkanolamine or trialkanolamine soap of a C.sub.10 -C.sub.20 saturated or monounsaturated fatty acid;
- (c) from about 0.001 to about 2 wt. % of at least one proteolytic enzyme; and
- (d) from about 5 to about 25 wt. % of at least one monohydroxy or polyhydroxy alcohol having 2 to 4 carbon atoms;
- wherein (a) and (b) taken together constitute from about 30 to about 50 wt. % of the detergent composition, and wherein a 1% aqueous solution of the detergent composition has a pH value in the range of from about 6.5 to about 9.
- 2. A detergent composition in accordance with claim 1 wherein (a) and (b) taken together constitute from about 35 to about 45 wt. % of the detergent composition.
- 3. A detergent composition in accordance with claim 1 wherein there is present in (a) from about 6 to about 8 parts by weight of component (i) wherein m=1 to 3, and n=4 to 8; and from about 2 to about 4 parts by weight of component (ii) wherein m=1 to 4, and n=12 to 16.
- 4. A detergent composition in accordance with claim 1 wherein in (a) the R group in Formula I is a mixture of groups which are from 25 to 100 wt. % monounsaturated and from 0 to 75 wt. % saturated, and which contain from 12 to 18 carbon atoms.
- 5. A detergent composition in accordance with claim 1 wherein (b) is from about 5 to about 20 wt. % of a sodium or triethanolamine soap of fatty acids which comprise from about 40 to 100 wt. % oleyl groups and from 0 to about 60 wt. % saturated linear fatty acids having from 12 to 18 carbon atoms.
- 6. A detergent composition in accordance with claim 1 wherein (d) is a mixture of 1,2-propylene glycol, and at least one of ethanol and isopropanol, wherein the weight ratio of monohydroxy alcohol to 1,2-propylene glycol is from about 5:1 to about 1:5.
- 7. A detergent composition in accordance with claim 1 wherein from about 0.5 to about 10 wt. % of free alkanolamine is also present therein.
- 8. A detergent composition in accordance with claim 1 wherein from about 0.1 to about 3 wt. %, based on free acid, of at least one water-soluble salt of a polycarboxylic acid or of a polyphosphonic acid is also present therein.
- 9. A detergent composition in accordance with claim 8 wherein the water-soluble salt of a polycarboxylic acid is a water-soluble salt of citric acid, and is present in from about 0.5 to about 3 wt. %.
- 10. A detergent composition in accordance with claim 8 wherein the water-soluble salt of a polyphosphonic acid is a water-soluble salt of an aminoalkane polyphosphonic acid.
