Solid fast draining/drying rinse aid for high total dissolved solid water conditions
First Claim
1. A method for rinsing ware which comprises plasticware in a warewashing application comprising:
- (a) providing a solid rinse aid composition which comprisesfrom about 65 wt % to about 85 wt % of one or more short chain alkyl benzene sulfonates and/or alkyl naphthalene sulfonates, wherein said one or more short chain alkyl benzene sulfonates have between 7 and 10 carbon atoms, and wherein said alkyl naphthalene sulfonates have between 10 and 18 carbon atoms and solidifies the rinse aid composition;
a surfactant system comprising at least three surfactants including one or more association disruption agents, from about 15 wt % to about 30 wt % of a sheeting agent; and
a defoamer;
(b) contacting the rinse aid composition with water to form a use solution; and
(c) applying the use solution to the ware which comprises plasticware to provide effective sheeting action to said ware.

Abstract
The present invention is a solid rinse aid composition and methods of making and using the same. 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 an 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.
