Abstract

A de-icing and anti-icing composition in the form of an aqueous solution which includes a low molecular weight carbohydrate, a inorganic freezing point depressant in the form of a chloride salt, and a thickener. The molecular weight of the carbohydrate is from about 180 to 500, with a preferred range of about 180 to 1000.

Claims

1. A de-icing and anti-icing composition comprising an aqueous solution which contains a low molecular weight carbohydrate and a chloride salt in which the constituents are present in the following concentration:

2. The composition of claim 1 in which the chloride salt is at least one selected from the group consisting of sodium chloride, magnesium chloride and calcium chloride.

3. The composition of claim 1 which further includes a colorant to provide visual aid in applying the composition to a surface.

4. A de-icing and anti-icing composition comprising an aqueous solution which contains a low molecular weight carbohydrate, a chloride salt, and a thickener in which the constituents are present in the following concentration:

5. The composition of claim 4 in which the chloride salt is at least one selected from the group consisting of sodium chloride, magnesium chloride and calcium chloride.

6. The composition of claim 4 which further includes a colorant to provide visual aid in applying the composition to a surface.

7. A de-icing and anti-icing composition comprising an aqueous solution which contains a low molecular weight carbohydrate and a chloride salt in which the constituents are present in the following concentration:

8. A de-icing and anti-icing composition comprising an aqueous solution which contains a low molecular weight carbohydrate, a chloride salt, and a thickener in which the constituents are present in the following concentration:
