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
