Rinse-aid formulation

Abstract

A stable aqueous rinse aid dispersion includes a low foaming nonionic surfactant present in a range of from about 2% to about 80% by weight of the rinse aid dispersion, a hydrotrope present in a range of from about 0.5% to about 20% by weight of the rinse aid dispersion, and a partially neutralized poly(meth)acrylic acid polymer present in a range of from about 0.1% to about 15% by weight of the rinse aid dispersion, wherein the polymer is at least 75% non-neutralized. The poly(meth)acrylic acid polymer has an average molecular weight in a range of from about 1000 to about 50,000. The rinse aid dispersion has a pH in a range of from about 2 to about 6. The stable aqueous rinse aid dispersion is essentially free of a high molecular weight compatibilizing polymer.
