The fire-retardant composition of U.S. Pat. No. 3,983,040 is improved to a surprising extent by the addition thereto of from about 10% to about 40% by weight of ammonium sulfate. In producing the improved composition, the patented composition is first made by reacting a pulverized borate ore selected from the group consisting of calcium, sodium, magnesium, and potassium borates and mixtures thereof, with sulfuric acid and water for a time sufficient to produce a substantially dry reaction product containing a boric acid constituent and a sulfate constituent. After drying, the reaction product is pulverized and the ammonium sulfate, also in pulverized condition, is intimately mixed therewith, or the two may be pulverized together to produce the final improved product. Cellulosic material is rendered fire-retardant by application of the product thereto.

An improved fire-retardant composition of matter for cellulosic material, comprising a mixture containing, as the principal ingredient, a reaction product of sulfuric acid and a borate ore, the latter being selected from the group consisting of calcium, sodium, magnesium, and potassium borates and mixtures thereof, said reaction product containing boric acid and a significant quantity of one or more sulfates selected from the group consisting of calcium, sodium,magnesium, and potassium sulfates; and, as a relatively minor ingredient, an effective amount of ammonium sulfate to render the composition substantially at least as effective a fire-retardant for cellulosic materials as is solely boric acid.
