Abstract
Solid rinse aid compositions and methods of making and using the same are disclosed. Solid rinse aid compositions include in a single concentrate composition a pyrithione preservative system to replace conventional preservatives in the isothiazolinone family, such as chloromethylisothiazolinone. Beneficially, the pyrithione preservative systems eliminate the need for any personal protective equipment to handle the solid rinse aid compositions. Methods of making and use using the rinse aids are also disclosed.
