Disclosed is an ethylene glycol based deicing/anti-icing composition which contains a thickener comprising a polyacrylic acid having a molecular weight of from about 90,000 to 100,000 and a wetting agent from the group consisting of nonylphenol ethoxylates, alkarylsulfonates, polyoxyethylene phosphates and tetrafunctional block copolymers of EO/PO on an ethylene diamine backbone and demonstrates improvement in anti-icing ability as measured by holdover time while not adversely effecting aerodynamic performance or Newtonian rheology of the deicer measured by passing the minimum requirements of the AMS test for Type I fluids.
