Abstract
forest fire retardant composition contains a retardant compound that includes a magnesium halide salt, a corrosion inhibitor, and a thickening agent. The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. The halide salt may be magnesium chloride. The magnesium chloride hydrate has a formula MgCl2(H2O)x wherein x is at least one of x = 1, 2, 4, 6, 8, or 12. The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.
