ABSTRACT:
The invention relates to a deicing or anti-icing composition comprising at least 0.01 to 0.5% wt of at least one alkali metal salt of polyaspartic or polyglutamic acids or a mixture thereof, having a total molecular weight of 5,000 to 50,000 g/mole as a flame retardant. The invention also relates to a method for deicing or preventing the formation of ice on a substrate by applying a composition to the substrate, wherein the composition comprises a flame retardant comprising alkali metal salts of polyaspartic or polyglutamic acids, or a mixture thereof, having a total molecular weight of between 5,000 and 50,000 g/mole, in proportions of 0.01 to 0.5 wt % in relation to the deicing or anti-icing composition. A method of making a deicing or anti-icing composition having a reduced electrochemical activity is also disclosed.
