Automatic dishwashing compositions having a detergent granule
The invention relates to detergent compositions comprising granular non-phosphate builder. The granules comprise an amino acid based builder, preferably MGDA, and s silicate. The composition is housed in a rigid PVOH capsule.
1. A method of automatic dishwashing in an automatic dishwashing machine, comprising:
providing a monodose automatic dishwashing detergent composition housed within a rigid polyvinyl alcohol capsule having one or more compartments; and
washing at least one aluminum-comprising article in an automatic dishwashing machine using the monodose automatic dishwashing detergent composition, wherein corrosion of the aluminum by the monodose automatic dishwashing detergent composition is inhibited;
wherein the monodose automatic dishwashing detergent composition consists of:
at least one non-ionic surfactant;
sodium citrate;
a bleaching compound;
a source of alkalinity;
a binder;
enzymes;
a dye;
an antifoam agent;
a fragrance;
a bleach activator;
a bleach catalyst;
a sulfonated polymer; and
at least one granule comprising, within the same granule, silicate together with methylglycine diacetic acid;
wherein the granule comprises 70-90% by weight methylglycine diacetic acid and 5-11% by weight of silicate,
wherein the total amount of builder present in the monodose automatic dishwashing detergent composition is up to 60% by weight, and
wherein the bleaching compound is a percarbonate bleach.
2. The method according to claim 1 , wherein the at least one granule comprises at least one further ingredient.
3. The method according to claim 1 , wherein the rigid polyvinyl alcohol capsule is selected from the group consisting of a thermoformed structure, a vacuum formed structure, an injection moulded structure, and a combination thereof.
4. The method according to claim 1 , wherein the at least one granule further comprises:
0-15% by weight of optional ingredients.
5. The method according to claim 1 , wherein the at least one granule has a diameter of 0.01 mm to 5 mm.
6. The method according to claim 1 , wherein the composition comprises a plurality of the granules.
7. The method according to claim 1 , wherein
the at least one non-ionic surfactant is present in an amount of 2% to 10% by weight based on the total weight of the detergent composition;
the sulfonated polymer is present in an amount of 0.1 to 10 wt % by weight based on the total weight of the detergent composition;
the antifoam agent is present in an amount of less than 0.5 wt % by weight based on the total weight of the detergent composition;
and the binder is present in an amount of about 4 wt % by weight based on the total weight of the detergent composition.
8. A method of automatic dishwashing in an automatic dishwashing machine, comprising:
providing a monodose automatic dishwashing detergent composition housed within a rigid polyvinyl alcohol capsule having one or more compartments; and
washing at least one aluminum-comprising article in an automatic dishwashing machine using the monodose automatic dishwashing detergent composition, wherein corrosion of the aluminum by the monodose automatic dishwashing detergent composition is inhibited; and
wherein the monodose automatic dishwashing detergent composition consists of:
at least one granule consisting of, within the same granule, methylglycine diacetic acid (MGDA), silicate and water;
percarbonate bleach;
at least one co-builder;
a source of alkalinity;
a binder;
enzymes;
a dye;
an antifoam agent;
a fragrance;
at least one non-ionic surfactant; and
a sulfonated polymer,
wherein the MGDA is present in the at least one granule in an amount of 70-90% by weight and the silicate is present in the at least one granule in an amount of 5-11% by weight, with the balance being water, and
wherein the total amount of builder present in the monodose automatic dishwashing detergent composition is up to 60% by weight.
9. The method according to claim 8 , wherein
the at least one non-ionic surfactant is present in an amount of 2% to 10% by weight based on the total weight of the detergent composition;
the sulfonated polymer is present in an amount of 0.1 to 10 wt % by weight based on the total weight of the detergent composition;
the antifoam agent is present in an amount of less than 0.5 wt % by weight based on the total weight of the detergent composition;
and the binder is present in an amount of about 4 wt % by weight based on the total weight of the detergent composition.
