Abstract: A method of manufacturing an automatic dishwashing detergent product, said product being provided as a discrete dosage unit and comprising a continuous, non-aqueous gel phase, comprises manufacturing the gel phase by a method comprising free radical polymerisation of monomer(s) in a non-aqueous reaction mixture to form a polymeric builder. The reaction mixture comprises: at least one non-ionic surfactant which is an optionally end-capped alcohol alkoxylate; and one or more monomers comprising acrylic acid, and optionally one or more further α,β-ethylenically unsaturated acids, wherein no more than 0.1 wt % of the total amount of the monomer(s) are crosslinking monomer(s). An automatic dishwashing detergent product provided as a discrete dosage unit, may comprise a continuous, non-aqueous gel phase comprising at least 10 wt % non-ionic surfactant and at least 20 wt % polymeric builder. The gel phase may be provided in a water soluble container.
