1. A fire retardant composition having a mold inhibitor, which comprises a mixture of a substantially neutral ammonium phosphate
salt in combination with an active hydrogen-containing nitrogenous organic compound spumific, and with a hydroxyl-containing
carbonific, and further with the mold inhibitor, wherein:
the substantially neutral ammonium phosphate salt has a pH about from 6 to 7½;
the hydroxyl-containing carbonific includes a polysaccharide resin other than starch; and
the fire retardant composition as a final product, when present as an aqueous solution, has a pH about from 6 to 7;
the mold inhibitor includes a quaternary organic ammonium halide in an amount sufficient in the final product to provide for
kill, control, or prevention of growth of Stachybotrys Chartarum when the final product is applied to a surface of a flammable wood substrate and dried to leave a residue therein and/or thereon;
and
the final product, when applied to the surface of the flammable wood substrate, can penetrate and, once dried, also leave
a see-through film on the surface of the substrate.
