Abstract

A rinse aid composition and a rinse aid concentrate which comprises an aqueous solution of a low foam surfactant, a solubilizing system for the low foam surfactant, and an anionic dispersing agent. This rinse aid controls foam, improves water solubility, reduces surface tension which improves sheeting action that reduces spotting, streaking and filming of the articles washed, provides an appropriate cloud point, and reduces drying time.
