Abstract

A process for producing detergent tablets containing more than 10% by weight of anionic surfactant wherein the detergent tablets contain detergent components which are at least partly in hydrated form and the anionic surfactant is present in the form of one or more compounds containing up to 95% by weight of surfactants, by exposing a mixture of the detergent components and the anionic surfactant to microwaves in the frequency range from 3 to 300,000 MHz.
