Abstract
A solid rinse aid composition and methods of making and using the same are described. Applicants have surprisingly found that the crystal modifier sodium xylene sulfonate (short chain alkyl benzene or alkyl naphthalene sulfonates) at higher percentage can act as a solidification agent. The solid rinse aid composition generally includes a short chain alkyl benzene or alkyl naphthalene sulfonates solidification agent and an effective amount of a surfactant which can include a sheeting agent component, defoamer component and/or association disruption agent. The solid rinse aid composition may be phosphate-free, aminocarboxylate-free, and GRAS if desired.
