Abstract
New solid detergent compositions and methods of forming and using those compositions are provided. The compositions for forming the solid detergents comprise a copolymer, scale inhibiting agent, and non-phosphate builder dispersed or dissolved in a solvent system. Advantageously, the inventive solid detergents provide dramatically improved cleaning performance and drying time without the use of a separate rinse additive. The detergents are especially suited to commercial dishmachine processes. The solid detergents are also in the form of a solid, homogeneous, self-sustaining body for improved handling and use.
