Abstract: A method for manufacturing an automatic dishwashing composition in the form of a non-aqueous gel, the method comprising: (i) combining one or more non-ionic surfactants, a polar non-aqueous solvent and a rheology modifier to form a non-aqueous gel, the non-aqueous gel having a pH of less than 7 when measured as a dilution of 1 part in 100 parts of water by weight, wherein the rheology modifier is an alkali-swellable emulsion polymer or a hydrophobically-modified alkali-swellable emulsion polymer; and (ii) adding to the non-aqueous gel one or more active agents selected from the group consisting of builders, surfactants, polymers, enzymes, bleaching agents, bleach activators, bleach catalysts and corrosion inhibitors to form the automatic dishwashing composition.
