Abstract
The present invention is a solid rinse aid composition and methods of making and using the same. The solid rinse aid composition generally includes sodium sulfate and urea as solidification agents and an effective amount of an alcohol ethoxylate compound sheeting agent component and an effective amount of defoamer component. The solid rinse aid composition may also incorporate a preservative system including sodium bisulfate. The solid rinse aid composition may be phosphate-free, aminocarboxylate-free, and GRAS if desired.
Claims20
A solid rinse aid composition comprising:
- sodium sulfate;
- urea;
- water;
- a sheeting agent comprising one or more alcohol ethoxylates;
- a defoamer component comprising a polymer compound including one or more ethylene oxide groups;
- sodium bisulfate;
- and sorbic acid and benzoic acid;
- wherein the total amount of sodium bisulfate and sorbic acid and benzoic acid is sufficient to provide a use solution having a pH less than 4.0 when the solid rinse aid composition is diluted at 10-500 parts of the solid rinse aid composition per million parts of aqueous diluent and a combined amount of sodium sulfate and urea is sufficient for solidification of the rinse aid composition.
