A nontoxic deicing/anti-icing fluid includes a biobased freezing point depressant, a surfactant, an antioxidant, and water. The fluid has an LDgreater 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.

Biobased deicing/anti-icing fluids

A nontoxic deicing/anti-icing fluid includes a freezing point depressant selected from short chain polyols having 3 to 5 carbons atoms, and mixtures thereof, a wetting agent, an antioxidant/preservative, and water. The fluid has an LDgreater than about 10,000 mg/L. Another deicing/anti-icing fluid includes the freezing point depressant, a vinylpyrrolidone polymer having a molecular weight between about 10,000 and about 700,000, and water. A runway deicing fluid includes glycerol, a buffer, an antioxidant/preservative, and water. Another deicing/anti-icing fluid includes a freezing point depressant having hydrophobic character, a wetting agent comprising an organophosphorus compound capable of producing an organic wettable surface, and water.

Deicing/anti-icing fluids

In a process for producing a deicing/anti-icing fluid, a byproduct stream is obtained from a process that produces monoalkyl esters of long chain fatty acids. The stream includes water, glycerol, and an alkali-containing compound. The stream is converted to a deicing/anti-icing fluid by adding an acid to the stream to neutralize the alkali-containing compound to produce an alkali salt that functions as a supplemental freezing point depressant.
