Abstract
A de-icing and anti-icing composition in the form of an aqueous solution which includes a carbohydrate, a freezing point depressant and an anti-corrosion agent in the form of phytic acid and its salts.
Claims8
A method for reducing the buildup of snow and ice on an outdoor surface, comprising:
- applying to the outdoor surface a composition comprising:
- an aqueous solution which contains a low molecular weight carbohydrate, a chloride salt and phytic acid and its salts in which the constituents are present in the following concentration:
- Weight % Carbohydrate 3 to 60 Chloride Salt 5 to 35 Phytic Acid and its salts 0.5 to 5.0 Water Balance
- and where said carbohydrate has a molecular weight in the range of about 180 to 1500, and is at least one selected from the group consisting of glucose, fructose and higher saccharides based on glucose and/or fructose and mixtures thereof.

A method for reducing the buildup of snow and ice on an outdoor surface, comprising:
- applying to the outdoor surface a composition comprising:
- an aqueous solution which contains a low molecular weight carbohydrate, a chloride salt, phytic acid and its salts, and a thickener in which the constituents are present in the following concentration:
- Weight % Carbohydrate 3 to 60 Chloride Salt 5 to 35 Phytic Acid and its salts 0.5 to 5.0 Thickener 0.15 to 10 Water Balance
- and where the carbohydrate has a molecular weight of about 180 to 1500, and is at least one selected from the group consisting of glucose, fructose and higher saccharides based on glucose and/or fructose and mixtures thereof, and where the thickener is selected from the group consisting of high molecular weight cellulose derivatives and carbohydrates in the range of about 60,000 to 1,000,000 for cellulose derivatives and 10,000 to 50,000 for carbohydrates, with said composition having a viscosity in the range of about 0.1 to 3 poises at 25° C.
