Patent ID: 7008918

Claim:
A rinse agent composition comprising: (a) sheeting agent comprising nonionic block copolymer surfactant in an amount for promoting draining of sheets of water from a surface, wherein the nonionic block copolymer comprises ethylene oxide and propylene oxide units; and (b) humectant comprising glycerine or propylene glycol, wherein the humectant comprises a material that contains greater than 5 wt. % water when the humectant is equilibrated at 50% relative humidity and room temperature; wherein the sheeting agent and the humectant are different and the weight ratio of the total amount of humectant in the rinse agent composition to the total amount of sheeting agent in the rinse agent composition is greater than 1:2, and wherein the rinse agent composition, when provided as an aqueous rinse containing an active materials concentration of 10 parts per million to 500 parts per million, reduces water solids filming in the presence of rinse water containing in excess of 200 parts per million total dissolved solids compared to an aqueous rinse not containing the humectant.
