Abstract
A detergent tablet having at least one phase in the form of a solid foam having gas-filled cells delimited by solid partitions, and the tablet or the at least one phase comprises 40% to 90% by weight of one or more water-soluble polymers. A process for the production of detergent tablets by foaming a solution, melt, emulsion, or suspension comprising at least one active ingredient with a gaseous medium, and solidifying the resulting foam.
