The present application relates to a deicing composition, specifically to a chlorine-free deicing composition, comprising at least two active ingredients selected from glycerol, a glycol-type compound and a salt of an organic acid. The deicing compositions of the present invention contain no chlorine-containing material, are relatively less corrosive to concrete and carbon steels, and have no toxic effect on plants. Moreover, the deicing compositions of the present invention have high deicing efficiency, which is, according to the Chinese national standard GB/T23851-2009, up to 200% of the efficiency of sodium chloride or more. In addition, the deicing compositions of the present invention maintain a long-lasting deicing effect (e.g., a deicing effect for up to 3 hours).

Environmentally friendly chlorine-free deicing composition
