12. The automatic dishwashing detergent composition according to claim 11 , wherein said water-soluble pouch is a multi-compartment pouch having a plurality of films forming a plurality of compartments.
13. The automatic dishwashing detergent composition according to claim 12 , wherein the pouch comprises two side-by-side compartments superposed onto another compartment wherein at least two different compartments contain two different compositions.
14. The automatic dishwashing detergent composition according to claim 11 , wherein at least two different compartments contain an anti-redeposition agent.
15. The automatic dishwashing detergent composition according to claim 11 , wherein one compartment contains a composition in solid form and another compartment contains a composition in liquid form.
16. A method of dishwashing in an automatic dishwashing machine comprising the step of placing a composition according to claim 1 into the product dispenser and releasing it during the main-wash cycle.
17. A method of preventing grit formation in automatic dishwashing comprising practicing the method of claim 16 .
18. A method of dishwashing in an automatic dishwashing machine using a detergent composition according to claim 1 comprising the steps of:
