Abstract
Deicing and anti-icing compositions comprising a succinate salt and at least one freezing point depressant selected from the group consisting of monohydric alcohols, polyhydric alcohols, monomethyl or monoethyl ethers of polyhydric alcohols, and mixtures thereof. The compositions have enhanced ice-melting capacity compared to the ice-melting capacity of the succinate salt or the alcohol alone, particularly at temperatures below about −10° C. The compositions are particularly useful as a windshield deicer/washer. Particular embodiments of the compositions are environmentally friendly.
