Abstract

In a process for dosing detergent compositions, which either are in the form of pastes or gels, or render such compositions when they are brought into contact with water, into a washing machine, the detergent composition is transported from a container for holding the composition to the washing machine via a conduit, whereafter said conduit is purged by means of a pressurized gas, preferably steam or air.

Claims

1. A process for dosing detergent compositions which are rendered in the form of paste or gels upon contact with water comprising:

(a) transporting a detergent composition which is rendered in the form of paste or gel upon contact with water from a container for holding the detergent composition to a washing machine via a conduit; and

(b) purging the conduit by means of a pressurized gas to clean the conduit while preventing blockages by the detergent composition.

2. A process according to claim 1, wherein the pressurized gas is steam or air.

3. A process according to claim 1, wherein the transporting step comprises pumping the detergent composition though the conduit.

4. A process according to claim 1, wherein the conduit has an end positioned below a water level inside a washing machine.

5. A process according to claim 4, wherein the conduit end is equipped with one or more nozzles.
