Process for producing a multi-phase detergent tablet

1. A process for the manufacture of a detergent tablet, wherein said process comprises the steps of:

forming a first body which includes a recess therein;

forming a second body by compaction or injection molding;

providing a gel comprising a non-aqueous liquid diluent into the recess of the pre-formed, first body;

providing the pre-formed, second body to the gel wherein at least 20% of the volume of the second body is beneath the upper surface of the gel; and

allowing or causing the gel to solidify wherein the second body is only partially submerged in the solidified gel, and,

only partially wrapping the tablet with foil wrapper before the gel is solidified.

2. A process according to claim 1 , wherein the recess of the first body has a mouth, the area of which is at least 50% larger than the largest diameter of the second body.

3. A process according to claim 1 , wherein the recess in the first body has its deepest point in the centre.

4. A process according to claim 1 , wherein the recess in the first body is impregnated, coated or foiled.

5. A process according to claim 1 , wherein the second body is a compressed pill.

6. A process according to claim 1 , wherein the gel forms a barrier layer between the first body and the second body.

7. A process according to claim 1 , wherein said non-aqueous liquid diluent comprises from 10% wt. to 60% wt. of said gel.

8. A process according to claim 7 , wherein said non-aqueous liquid diluent comprises from 20% wt. to 50% wt. of said gel.

9. A process according to claim 1 , wherein said non-aqueous liquid diluent and said organic or polymeric gelling additive are present in a respective weight ratios from 99:1 to 1.1.

10. A process according to claim 9 , wherein said non-aqueous liquid diluent and said organic or polymeric gelling additive are present in a respective weight ratios from 19:1 to 4:1.
