Abstract

The invention relates to an automatic dishwashing detergent composition that is formulated to provide effective cleaning at low temperatures.

First claim

The invention claimed is:

1. A detergent composition comprising:
at least one low temperature emulsifying surfactant present between 0.0001 and 1% by weight of the composition;
an oxidation catalyst present between 0.005 and 1% by weight of the composition; and
at least one enzyme present between 0.01 to 5% by weight of the composition;
wherein at least one low temperature emulsifying surfactant is selected from the following formula:
R—CO—NMe-CH 2 —CH 2 —SO 3 —X

wherein R is a saturated or unsaturated, straight or branched, alkyl chain of between 6 and 18 carbons;
wherein X is a positively charged counter ion; and
wherein the detergent composition is an automatic dishwashing detergent composition suitable for low temperature cleaning at less than or equal to 50° C.

2. The detergent composition according to claim 1 , wherein at least one low temperature emulsifying surfactant is sodium methyl cocoyl taurate.

3. The detergent composition according to claim 1 , wherein the composition comprises a second low temperature emulsifying surfactant comprising C 13 -13EO-butylene oxide.

4. The detergent composition according to claim 1 , wherein at least one low temperature emulsifying surfactant is present between 0.005 and 1% by weight of the composition.

5. The detergent composition according to claim 1 , wherein the composition is in the form selected from the group consisting of a compressed tablet, powder, liquid, PVOH gel pack and rigid PVOH capsule.

6. The detergent composition according to claim 1 , wherein the detergent composition is an automatic dishwashing detergent composition suitable for low temperature cleaning at less than or equal to 45° C.

7. The automatic detergent composition according to claim 6 , wherein at least one low temperature emulsifying surfactant is present between 0.0005 and 0.05% by weight of the composition.
