Abstract
A non-Newtonian concentrate composition includes a sensitizer or irritant, a surfactant, an anti-mist component and optionally a stability component. Example sensitizers and irritants include, but are not limited to, acids, quaternary compounds, and amines, and example anti-mist components include, but are not limited to, polyethylene oxide and polyacrylamide.
Claims50
A non-Newtonian aqueous concentrate composition comprising:
- at least one acid;
- at least one surfactant;
- and
- at least one anti-mist component selected from the group consisting of polyethylene oxide, polyacrylamide and polyacrylate, wherein the composition is a non-Newtonian having a viscosity of less than about 40 centipoise.
A method of forming a use solution, the method comprising:
- mixing water with a concentrate aqueous composition to create the use solution, the concentrate aqueous composition comprising:
- at least one surfactant;
- and
- at least one anti-mist component selected from the group consisting of polyethylene oxide and polyacrylamide, wherein the concentrate aqueous composition is mixed with sufficient water to form a use solution having between about 0.002% and about 0.006% by weight anti-mist component.
A method of forming a use solution, the method comprising:
- mixing water with a concentrate aqueous composition to create the use solution, the concentrate aqueous composition comprising:
- at least one surfactant;
- and
- a polyacrylate, wherein the concentrate aqueous composition is mixed with sufficient water to form a use solution having between about 0.2% and about 5% by weight polyacrylate.
A method of using a sprayable composition, the method comprising:
- dispensing an aqueous sprayable composition as droplets having a mean size of greater than 50 microns using a low velocity sprayer, the aqueous sprayable composition comprising at least one surfactant and at least one surfactant and between about 0.002% and about 0.006% by weight of an anti-mist component selected from the group consisting of polyethylene oxide, polyacrylamide and combinations thereof.
A method of using a sprayable composition, the method comprising:
- dispensing an aqueous sprayable composition as droplets having a mean size of greater than about 50 microns using a low velocity sprayer, the aqueous sprayable composition comprising at least one surfactant and between about 0.2% and about 5.0% by weight of a polyacrylate.
