Abstract
A rinse aid composition for use on plasticware is herein described which requires lower concentration of conventional hydrocarbon surfactants, exhibits adequate sheeting on the plasticware and acceptable drying time which prior rinse aids have failed to provide without special handling. The compositions described contain hydrocarbon surfactants and a polyether or polybetaine polysiloxane copolymer surfactant alone or in combination with a fluorinated hydrocarbon surfactant. The composition may be formulated as a solid or liquid suitable for dilution to form an aqueous rinse used to contact the plasticware in a warewashing machine.
