Abstract
Abstract A novel chloride salt based de-icing composition comprising a corrosion inhibitor of a de-sugared sugar beet molasses. The corrosion inhibited de-icing compound comprises from 5 to 25 percent by weight of de-sugared molasses compared with the weight percent of the chloride salt in the de-icing composition.
