  • Patent number: 5783540
    Abstract: A solid detergent composition and a method of using the composition in a machine dishwasher is described. The product contains a first layer having an oxygen bleaching system, a buffering system of a builder, and an enzyme. The first layer dissolves to deliver a pH of about 8.5 to about 11 in the wash water. A second layer includes an effective amount of an acidity agent selected from an inorganic acid, an organic acid and mixtures thereof, a continuous medium having a melting point in the range of from about 55.degree. C. to about 70.degree. C. and an anti-scaling agent. The second layer dissolves in wash water to deliver a pH of from about 6.5 to about 9.
