Abstract

The need for a cleaning product comprising a spray dispenser and a cleaning composition, which provides improved polymeric grease cleaning and suds mileage, and hence reduced time to clean the dishes, is met by a cleaning product comprising a spray dispenser and a cleaning composition, the composition is housed in the spray dispenser and wherein the cleaning composition comprises anionic surfactant and alkyl glucamide surfactant.

First claim

What is claimed is:

1. A cleaning product comprising a spray dispenser and a cleaning composition, wherein:
the cleaning composition is housed in the spray dispenser;
the cleaning composition comprises from about 5% to about 25% by weight of the cleaning composition of a surfactant system; and
the surfactant system comprises:
a. an anionic surfactant;
b. an alkyl glucamide surfactant, wherein the alkyl glucamide surfactant has the formula:

wherein in formula (I):
R1 is a linear or branched, saturated or unsaturated alkyl chain comprising from 8 to 18 carbon atoms; and
R2 is an alkyl group having from 1 to 4 carbon atoms;
wherein the anionic surfactant and alkyl glucamide surfactant are present at a weight ratio of greater than about 1:1; and
the cleaning composition has a Newtonian viscosity of from 1 to 50 mPa·s.

2. The cleaning product according to claim 1 , wherein the cleaning composition comprises from about 7% to about 20% by weight thereof of the surfactant system.

3. The cleaning product according to claim 1 , wherein the cleaning composition comprises the anionic surfactant at a level of from about 2.0 to about 12% by weight of the composition.

4. The cleaning product according to claim 1 , wherein in the surfactant system of the cleaning composition, the anionic surfactant comprises: alkyl sulphated anionic surfactant selected from the group consisting of: alkyl sulphate, alkyl alkoxy sulphate, and mixtures thereof.

5. The cleaning product according to claim 4 , wherein the alkyl sulphated anionic surfactant has an average degree of alkoxylation, of no more than about 5.0.

6. The cleaning product according to claim 5 , wherein the alkyl sulphated anionic surfactant has an average degree of alkoxylation, of from about 1.0 to about 5.0.

7. The cleaning product according to claim 1 , wherein the cleaning composition comprises the alkyl glucamide at a level of from about 0.5% to about 5.0% by weight of the cleaning composition.

8. The cleaning product according to claim 7 , wherein the cleaning composition comprises the alkyl glucamide at a level of from about 1.0% to about 4.0% by weight of the cleaning composition.

9. The cleaning product according to claim 1 , wherein in the alkyl glucamide surfactant, R1 is a C8-C14 alkyl chain.

10. The cleaning product according to claim 9 , wherein in the alkyl glucamide surfactant, R1 is a C12-C14 alkyl chain.

11. The cleaning product according to claim 1 , wherein the anionic surfactant and alkyl glucamide surfactant are present at a weight ratio of from greater than about 1:1 to about 10:1.

12. The cleaning product according to claim 1 , wherein the surfactant system comprises a further nonionic surfactant at a level of from about 1.0% to about 10% by weight of the composition.

13. The cleaning product according to claim 12 , wherein the further nonionic surfactant is an alkyl ethoxylate surfactant.

14. The cleaning product according to claim 13 , wherein the alkyl ethoxylate surfactant has an average alkyl chain length of C10 or below, and a number average degree of ethoxylation of from about 1 to about 10.

15. The cleaning product according to claim 1 , wherein the surfactant system comprises less than about 0.5% by weight of the cleaning composition of an amphoteric surfactant, zwitterionic surfactant, and mixtures thereof.

16. The cleaning product according to claim 15 , wherein the surfactant system is free of amphoteric and zwitterionic surfactant.

17. The cleaning product according to claim 1 , wherein the composition comprises organic solvent at a level of from about 0.1% to about 10% by weight of the composition.

18. The composition according to claim 17 , wherein the organic solvent is selected from the group consisting of: glycol ether solvents, alcohol solvents, ester solvents, and mixtures thereof.

19. The cleaning product according to claim 1 , wherein the composition is free of enzymes.

20. A method of cleaning dishware using the cleaning product according to claim 1 , comprising the steps of:
a) optionally pre-wetting the dishware;
b) spraying the cleaning composition onto the dishware;
c) optionally scrubbing the dishware; and
d) rinsing the dishware.
