Abstract
The present invention provides fire-retardant compositions for treatment of wood products comprising a guanidine phosphate compound and a boron compound, such as boric acid. The present invention also provides a method for using the compositions for preparing a fire-retardant cellulosic material, such as wood, comprising the step of applying a fire-retardant composition comprising an aqueous solution of guanidine phosphate and a boron-containing compound to a cellulosic material, thereby rendering the cellulosic material fire retardant. The present invention also provides a method of preparing a fire-retardant composition comprising mixing a guanidine phosphate and a boron-containing compound.
