Abstract An improved concentrate for pre-loaded dispenser cups whose contents are diluted with water prior to use wherein the concentrate includes a non-volatile, water miscible liquid or powdered solid wetting agent. Glycerine is a suitable liquid wetting agent. Polyethylene glycol 20M is a suitable powdered solid wetting agent. The concentrate may be placed in the cup either as a slurry of solids in a liquid, as a powdered solid, or as a powdered solid adhered to a layer of gelatin contained in the cup.
