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.
Claims26
A rinse agent composition comprising:
- (a) sheeting agent for promoting draining of sheets of water from a surface;
- (b) humectant;
- wherein the sheeting agent and the humectant are different and the weight ratio of the humectant to the sheeting agent is greater than 1:3.
A method for rinsing a substrate surface in the presence of high solids containing water, the method comprising:
- (a) applying an aqueous rinse agent composition to a substrate surface, said aqueous rinse agent composition comprising:
- (i) sheeting agent for promoting draining of sheets of water from a surface;
- and
- (ii) humectant;
- wherein the sheeting agent and the humectant are different and the weight ratio of humectant to sheeting agent is greater than about 1:3.
