  • Patent number: 5900395
    Abstract: A solid detergent composition useful for machine dishwashing is described. The product contains a first layer having an oxygen bleach system, a buffering system, 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 and a continuous medium having a melting point in the range of from about 35.degree. C. to about 50.degree. C. The material may be a paraffin wax, a natural wax, a polyvinyl ether, fatty acids and mixtures thereof. The second layer dissolves in wash water to deliver a pH of from about 6.5 to about 9. The release order of the functional ingredients allows for a high level of peracid species generation in the initial wash stages followed by optimum bleaching throughout the wash.
