Abstract
A rinse aid composition and methods of making and using the same. A rinse aid composition may generally include an effective amount of a sheeting agent component, and an effective amount of a defoamer component. The sheeting agent component may include one or more alcohol ethoxylate compounds that include an alkyl group that includes 12 or fewer carbon atoms. The defoamer component may include an ethylene oxide containing surfactant configured for reducing the stability of foam that may be created by the one or more alcohol ethoxylate compounds of the sheeting agent in an aqueous solution.
