Abstract
A deicing composition comprising saccharinic acid, lignosulfonate and an alkali metal or alkaline earth metal chloride selected from among sodium chloride, magnesium chloride, calcium chloride and mixtures thereof, the ratio of said saccharinic acid, lignosulfonate and chloride being from about 0.05:0.95:15 to about 0.75:2.25:1. The composition has a pH value of from about 5.0 to 9.5. The saccharinic acid contemplated for use in the composition is isosaccharinic or metasaccharinic acid, or mixtures thereof. The saccharinic acid may be conveniently derived from the alkali treatment of monosaccharides and oligosaccharides inherently contained in spent sulfite liquor by heating at a temperature of 50.degree. C. to 150.degree. C., preferably at 80.degree. C. to 100.degree. C.
