ABSTRACT:
A nontoxic deicing/anti-icing fluid includes a biobased freezing point depressant, a surfactant, an antioxidant, and water. The fluid has an LD50greater than about 10,000 mg/L. Another deicing/anti-icing fluid includes a biobased freezing point depressant, a vinylpyrrolidone polymer having a molecular weight between about 10,000 and about 700,000, and water. Another deicing/anti-icing fluid includes a biobased freezing point depressant, a nonionic surfactant selected from the polyoxyalkylene ethers, an antioxidant, and water. Another deicing/anti-icing fluid includes a biobased freezing point depressant, a surfactant, a food grade material that functions as an antioxidant, and water. A further deicing/anti-icing fluid includes a biobased freezing point depressant, a material that functions as both a buffer and a freezing point depressant, and water.
