A stabilized hydroxylammonium nitrate or hydroxylamine-containing composition comprising said hydroxylammonium nitrate or hydroxylamine and a pyridine or pyridone salt, or an acid thereof, said pyridine or pyridone salt, or acid thereof, being present in said composition in an amount of between about 0.0001% and about 2%, based upon the weight of said composition, wherein said pyridine or pyridone salt is the sodium salt of 2-hydroxypyridine-N-oxide. A stabilized hydroxylammonium nitrate or hydroxylamine-containing composition comprising said hydroxylammonium nitrate or hydroxylamine and a pyridine or pyridone salt, or an acid thereof, said pyridine or pyridone salt, or acid thereof, being present in said composition in an amount of between about 0.0001% and about 2%, based upon the weight of said composition, wherein said pyridine or pyridone salt is represented by the structural formula: [Figure] wherein X is a moiety selected from the group consisting of SH, OH and NH2, n is an integer of 1 or 2, and R is hydrogen or a lower alkyl or lower alkoxy group having from one to six carbons. A stabilized hydroxylammonium nitrate or hydroxylamine-containing composition comprising said hydroxylammonium nitrate or hydroxylamine and a pyridine or pyridone salt, or an acid thereof, said pyridine or pyridone salt, or acid thereof, being present in said composition in an amount of between about 0.0001% and about 2%, based upon the weight of said composition, wherein said pyridine or pyridone salt is represented by the structural formula: [Figure] wherein R′is a moiety selected from the group consisting of hydrogen and a lower alkyl group having from one to six carbons. A stabilized hydroxylammonium nitrate or hydroxylamine-containing composition comprising said hydroxylammonium nitrate or hydroxylamine and a pyridine or pyridone salt, or an acid thereof, said pyridine or pyridone salt, or acid thereof, being present in said composition in an amount of between about 0.0001% and about 2%, based upon the weight of said composition, wherein said pyridine or pyridone salt is represented by the structural formula: [Figure] wherein R″is a moiety selected from the group consisting of hydrogen and a lower alkyl group having from one to six carbons, and R′″is a lower alkyl or lower alkoxy group having from one to six carbons. A stabilized hydroxylammonium nitrate or hydroxylamine-containing composition comprising said hydroxylammonium nitrate or hydroxylamine and a pyridine or pyridone salt, or an acid thereof, said pyridine or pyridone salt, or acid thereof, being present in said composition in an amount of between about 0.0001% and about 2%, based upon the weight of said composition, wherein said pyridine or pyridone salt is selected from the group consisting of: zinc pyrithione, copper pyrithione, manganese pyrithione, nickel pyrithione, cobalt pyrithione, bismuth pyrithione, zirconium pyrithione, 1-hydroxy-6-substituted pyridiones having a 6-ring substituent selected from the group consisting of -O-R and -S-R, wherein O is oxygen, S is sulfur, and R is a substituted or unsubstituted hydrocarbon radical having between 1 and 20 carbon atoms, and combinations thereof.
