Abstract

A liquid hard surface detergent composition comprising a liquid mixed alkoxylate fatty alcohol non-ionic surfactant comprising a greater number of the lower higher alkoxylate group than the higher alkoxylate group in the molecule and a builder. The compositions provide good shine/anti-spotting characteristics on hard surfaces and are especially suitable for use as automatic dishwashing compositions.

First claim

What is claimed is:

1. A composition comprising:
a liquid mixed alkoxylate fatty alcohol non-ionic surfactant comprising at least one lower alkoxylate group and at least one higher alkoxylate group, wherein there is a greater number of moles of the lower alkoxylate group than of the higher alkoxylate group in the molecule, wherein the liquid mixed alkoxylate fatty alcohol non-ionic surfactant has the formula:
R1-[EO] n -[PO] m -[BO] p -Bu q

wherein:
R1 is an alkyl group of between C8 and C20;
EO is ethylene oxide;
PO is propylene oxide;
BO is butylene oxide;
Bu is butylene;
n is an integer from 6 to 10;
m is an integer from 3 to 5;
p is 0;
q is 0; and

a builder,
wherein the composition is a liquid hard surface detergent composition.

2. The composition according to claim 1 , wherein the composition is a liquid automatic dishwashing detergent composition.

3. The composition according to claim 1 , wherein the composition is a gel.

4. The composition according to claim 1 , wherein the liquid mixed alkoxylate fatty alcohol nonionic surfactant comprises 4 moles of PO and 8 moles of EO in the molecule.

5. The composition according to claim 1 , wherein the composition comprises at least 2 wt % of the liquid mixed alkoxylate fatty alcohol non-ionic surfactant.

6. The composition according to claim 1 , wherein the liquid mixed alkoxylate fatty alcohol nonionic surfactant is derived from a linear chain fatty alcohol having 12-18 carbon atoms.

7. The composition according to claim 1 , wherein the liquid mixed alkoxylate fatty alcohol nonionic surfactant has at least 10 moles of alkylene oxide per mole of alcohol.

8. The composition according to claim 1 , wherein the liquid mixed alkoxylate fatty alcohol nonionic surfactant comprises 4 or 5 moles of PO and 7 or 8 moles of EO.

9. The composition according to claim 1 , wherein the builder is selected from the group consisting of phosphate-containing builders, polycarboxylic acids and their salts, and amino acid based builders.

10. The composition according to claim 9 , wherein the builder is selected from the group consisting of tripolyphosphates, citrates, MGDA and GLDA and salts or derivatives and mixtures thereof.

11. The composition according to claim 1 , wherein the composition comprises at least 10 wt % of the builder.

12. The composition according to claim 1 , wherein the composition further comprises a polymer.

13. The composition according to claim 12 , wherein the polymer is a sulphonated polymer.

14. The composition according to claim 13 , wherein the sulphonated polymer comprises monomers of a carboxylic acid or a salt thereof and a sulphonated monomer.

15. The composition according to claim 1 , wherein the composition further comprises an additional non-ionic surfactant.

16. The composition according to claim 1 , wherein any solvent included in the composition is present in an amount of no more than 10 wt %.

17. The composition according to claim 1 , wherein the composition is prepared at a temperature in the range of from 25-80° C.

18. The composition according to claim 1 , wherein the composition is in the form of a unit dose and is enveloped in a water soluble or water dispersible package.

19. The composition according to claim 18 , wherein the water soluble or water dispersible package has a plurality of compartments.

20. The composition according to claim 18 , wherein the water soluble or water dispersible package comprises polymeric packaging material.
