Disclosed is a deicing composition comprising (i) a deicing agent selected from the group consisting of sodium chloride, calcium magnesium acetate, calcium chloride, magnesium chloride, potassium chloride, potassium acetate, sodium acetate, sodium formate, potassium formate, (ii) a lignin derivative, and (iii) molasses. The deicing composition remains effective over a longer period of time, so that the deicing agent can be applied less frequently and the damage to especially highly porous road surfaces will be reduced. Also disclosed is a process for preparing the deicing composition and to a process for deicing a surface using the deicing composition. In certain embodiments the lignin derivative is lignosulphonate. In certain embodiments the molasses is selected from the group consisting of molasses derived from corn (syrup), sugar beet, sugar cane, and grapes. |
