Abstract
A rinse agent composition is provided. The rinse agent composition includes a sheeting agent for promoting draining of sheets of water from a surface, and a humectant. The humectant is a component which retains at least 5 wt. % water when the humectant has been contained at an equilibrium of 50% relative humidity and room temperature. The sheeting agent and humectant are preferably provided at a ratio of between about 5:1 and about 1:3. A method for rinsing a substrate surface in the presence of high solids containing water is provided. High solids containing water is generally considered to be water having a total dissolved solids content in excess of 200 ppm.
Claims14
A rinse agent composition comprising:
- (a) sheeting agent comprising nonionic block copolymers having ethylene oxide and propylene oxide units for promoting draining of sheets of water from a surface;
- and
- (b) humectant comprising at least one of alkyl polyglycoside, polybetaine polysiloxane, and mixtures thereof;
- 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 1:3, and wherein the rinse agent composition provides a use solution exhibiting reduced water solids filming.
