ABSTRACT:
A concentrated deicing and anti-icing composition which is diluted and is primarily used for aircraft surfaces being a mixture including a deicing and anti-icing base compound being propylene glycol and/or ethylene glycol in the overall range of 78.0% to 95.0% by weight of the deicing and anti-icing composition. A diluent is included in the form of water for use as a carrier fluid of the glycol in the overall range of 5.0% to 22.0% by weight of the deicing and anti-icing composition. A first nonionic surfactant agent is included having an HLB in the overall range of 4 to 17; and used in a weight proportion where the overall range is 1 ppm to 0.5% by weight of the deicing and anti-icing composition. A second nonionic surfactant agent is included having an HLB in the overall range of 5 to 18; and used in a weight proportion where the overall range is 1 ppm to 0.5% by weight of the deicing and anti-icing composition. The second nonionic surfactant agent has an HLB at least two (2) units higher than the first nonionic surfactant agent. An emulsifier is included in the form of a polycarboxylate compound being in the overall range of 1 ppm to 0.5% by weight of the deicing and anti-icing composition. A pH control agent maintains the pH of the deicing and anti-icing composition between a 6 and 10 value; and used in a weight proportion where the overall range is 1 ppm to 1.0% by weight of the deicing and anti-icing composition.
