Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 58 words
A de-icing and anti-icing composition comprising an aqueous solution which contains mixtures of sugars and a chloride salt in which the constituents are present in the following concentration: Weight % Sugars 3 to 60 Chloride Salt 5 to 35 Water Balance and wherein the molecular weight of each of the sugars is in the range of about 180-1638.
Claim 2
Dependent Claim 58 words
A de-icing and anti-icing composition comprising an aqueous solution which contains mixtures of sugars and a chloride salt in which the constituents are present in the following concentration: Weight % Sugars 3 to 60 Chloride Salt 5 to 35 Water Balance and wherein the molecular weight of each of the sugars is in the range of about 180-1638.
Claim 3
Dependent Claim 27 words
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.
Claim 4
Dependent Claim 21 words
The composition of claim 1 which further includes a colorant to provide visual aid in applying the composition to a surface.
Claim 5
Dependent Claim 21 words
The composition of claim 1 in which the composition has a viscosity of about 0.1 to 3 poises at 25° C.
Claim 6
Dependent Claim 64 words
