Abstract
Surfactant systems and compositions incorporating the same are disclosed for use as rinse aids on plastics and other wares. The surfactant systems and compositions include both liquid and solid formulations, along with methods of use for treating plastics and other wares. The surfactant systems and compositions provide synergistic combinations allowing lower actives in composition formulations of the plastic-compatible surfactant systems providing good sheeting, wetting and drying properties.
