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