Tablet binding compositions

Abstract

Provided are tablet binding compositions for binding cleaning and/or disinfecting formulation components into tablets. The tablet binding compositions are suitable replacements for traditional tablet binder compounds, such as boric acid or zeolites. The tablet binding compositions provided herein can produce tablets of increased hardness at lower compression forces and, when dissolved, yield solutions of increased clarity compared to some traditional binder compounds. Also provided are processes for preparing the tablet binding compositions and methods for formation of tablets containing the tablet binding compositions.
