A wafer, readily soluble in the mouth to form a refreshing and antiseptic mouthwash, comprising a dried, aqueous emulsion of a sweetener, a flavouring agent, a bactericide which is safe for internal use and a watersoluble stabilizer which is edible and physiologically innoxuous, may be prepared by adding the stabilizer to an aqueous solution of sweetener, flavouring agent, preservative and bactericide while stirring vigorously until the resulting emulsion attains a viscosity of 700 to 1500 cps at 20‹C, casting the emulsion on a non-sticky surface and drying at 80‹ to 105‹C, to a moisture content of 5-15% by weight. The wafer may comprise 0.5 to 30% by weight of sweetener e.g. Na or Ca cyclamate, and/or saccharin; 5 to 50% by weight of flavouring agent e.g. oil of peppermint, anise, cloves, lemon, orange, cinnamon, menthol or eucalyptus; 0.01 to 0.25% by weight of a preservative such as benzoic acid, a benzoate, sorbic acid and/or a sorbate, 0.02 to 0.04% by weight of the bactericide e.g. an n-alkyl (C 12 , C 14 , C 16 ) dimethylbenzylammonium chloride, cetyl pyridinium chloride and/or hexyl resorcinol and 10 to 85% by weight of the stabilizer e.g. methyl cellulose, an alkali metal carboxymethyl cellulose, and/or an alginate.
