Solid dishmachine detergent not requiring a separate rinse additive

摘要

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.

主权项

1. A method of removing soils from a substrate surface comprising:
providing a substrate having a surface with soils thereon; dissolving or dispersing a solid detergent composition in water to form a wash solution, said detergent composition being in the form of a homogeneous, self-sustaining body formed by mixing ingredients with a solvent system, and allowing the mixture to harden to form said homogeneous, self-sustaining body, said ingredients comprising:
a copolymer of a quarternary ammonium compound and a comonomer selected from the group consisting of acids, acrylamides, and combinations thereof;a scale inhibiting agent; anda non-phosphate builder; and said homogeneous, self-sustaining body comprising a moisture content of from about 2 to about 40% by weight, based on the total weight of the self-sustaining body taken as 100% by weight; contacting said substrate surface with said wash solution; removing the soils from said substrate surface; and rinsing said substrate without the use of a rinse additive.
