Abstract
A composition and method for the protection of an exposed body of water comprising 5-95 wt % silicone polymer; greater than zero percent to 90 wt % carrier material; and greater than zero −20 wt % surfactant. The method includes the steps of adding the composition to the surface of the water and allowing the composition to form a liquid film across the surface of the water. The film is effective for reducing evaporation of water from the surface.

1-16. (canceled)
A non aqueous composition for the protection of a body of water comprising:
- greater than 70 to 95 wt % silicone polymer;
- greater than zero to less than 20 wt % carrier material, wherein the carrier material is mineral oil or vegetable oil;
- greater than zero to 20 wt % surfactant;
- wherein a substantially continuous protective film is formed across a surface of the body of water when the composition is applied to the surface at a rate of 0.3 to 90 g/m2 and said protective film of said composition floats upon the body of water, lasts four weeks, reduces evaporation of water about 80% to about 90% from the body of water, and has a surface tension of 21 dynes.

A non aqueous composition for the protection of a body of water consisting of:
- 70 to 95 wt % dimethylsiloxane;
- 5 to 10 wt % vegetable oil;
- 0.5 to 10 wt % surfactant;
- wherein said composition has a surface tension of 21 dynes and a viscosity of 1000 centistokes at 25° C.;
- wherein a substantially continuous protective film is formed across a surface of the body of water when the composition is applied to the surface at a rate of 0.3 to 90 g/m2 and said protective film of said composition floats upon the body of water, and lasts four weeks;
- and,
- wherein said protective film of said composition reduces evaporation of water about 80% to about 90% from the body of water.
