摘要：Ethylene oxide/propylene oxide block copolymers having high cloud points,when compared to conventional rinse agent materials, have surprisingly been found to beuseful in the manufacture of effective low foaming rinse aids. The rinse aids are preparedby combining the high cloud point copolymer with an effective defoamer and a watermiscible diluent. The rinse aid composition can achieve adequate rinsing at commonaqueous rinse temperatures at a concentration of the block copolymer in water less than500 parts of the block copolymer per million parts of water. A liquid rinse agentconcentrate can take the form of a low viscosity liquid, a thickened pourable or semi-pourable aqueous liquids. A solid rinse agent concentrate can be a cast solid materialpackaged within a soluble or disposable wrapper or capsule or other water solublepackage. The rinse aids can be dispersed in a variety of ways by dilution with water to anaqueous final rinse composition. The uniqueness of the invention relates to the fact thatall components are not expected to be active as sheeting agents and are approved asfood additives thereby eliminating any health concerns associated with residual depositsof the composition on cleaned ware.
