Abstract

The application is directed to a nonaqueous liquid automatic dishwasher detergent composition with improved anti-filming and anti-spotting properties and to a method of using the detergent composition. The detergent composition comprises a nonaqueous organic carrier liquid, silica, alumina or titanium dioxide anti-filming agent, a water soluble polyacylate anti-spotting agent, inorganic builder salts, bleach compound and detergent. The compositions provide reduced filming and spotting on dishware, glassware, china and the like, particularly in hard water. The nonaqueous liquid automatic dishwasher detergent compositions are stable in storage and are readily dispersible in water.
