Magnesium chloride and potassium sulfate deicer
View Patent ↗Deicing compositions comprising magnesium chloride and potassium sulfate are provided. The compositions are pet friendly and have less of a detrimental impact on the environment and vegetation than prior art compositions. Methods of reducing or preventing the build-up of ice or snow on various surfaces are also provided.
1. A deicing composition consisting essentially of magnesium chloride and potassium sulfate, wherein the weight ratio of magnesium chloride to potassium sulfate is from about 50:50 to about 95:5.
2. The composition of claim 1 , wherein said composition is a blend of discrete pieces of magnesium chloride and potassium sulfate.
3. The composition of claim 2 , said pieces being selected from the group consisting of pellets, cubes, granules, flakes, powder, crystals, and mixtures thereof.
4. The composition of claim 1 , wherein said magnesium chloride comprises magnesium chloride hexahydrate.
5. The composition of claim 1 , wherein said potassium sulfate comprises agricultural grade potassium sulfate granules or pellets.
6. The composition of claim 1 , said composition having a moisture content of from about 0% to about 5% by weight, based upon the total weight of the composition taken as 100% by weight.
7. A method of melting or preventing the build-up of ice or snow on a surface, said method comprising applying a composition consisting essentially of magnesium chloride and potassium sulfate to said surface.
8. The method of claim 7 , wherein said composition is a blend of discrete pieces of magnesium chloride and potassium sulfate.
9. The method of claim 7 , said applying comprises dispersing said composition substantially uniformly over said surface.
10. The method of claim 7 , wherein said surface is selected from the group consisting of a roadway, driveway, walkway, sidewalk, patio, porch, parking lot, and other paved surfaces.
11. The method of claim 7 , wherein said composition is applied at a level of from about 10 to about 100 grams of composition per square yard of said surface.
12. A method of melting or preventing the build-up of ice or snow on a surface, said method comprising applying a composition comprising magnesium chloride and potassium sulfate to said surface, said composition being substantially free of magnesium sulfate, calcium chloride, sodium chloride, glycerol-containing by-products, and alcohols.
13. The method of claim 12 , said applying comprises dispersing said composition substantially uniformly over said surface.
14. The method of claim 12 , wherein said surface is selected from the group consisting of a roadway, driveway, walkway, sidewalk, patio, porch, parking lot, and other paved surfaces.
15. The method of claim 12 , wherein said composition is applied at a level of from about 10 to about 100 grams of composition per square yard of said surface.
16. A deicing composition consisting essentially of magnesium chloride and potassium sulfate, said composition having a moisture content of from about 0% to about 5% by weight, based upon the total weight of the composition taken as 100% by weight.
