The present invention relates to a stabilized isothiazolone composition and a method of stabilization of isothiazolone, more particularly, to a stabilized isothiazolone solution comprising (a) isothiazolone composition represented by formula (1), (b) sulfuric acid, and (c) solvent. Wherein, R1 and R2, which are the same or different, respectively represent a hydrogen atom; a halogen atom; or C1-C4 alkyl group; or R1 and R2 together form a cyclic allyl group; R3 represents C1-C10 alkyl group which is substituted or unsubstituted with a hydrogen atom, a halogen atom or hydroxy group; C2-C10 alkenyl group which is substituted or unsubstituted with a halogen atom; C2-C10 alkynyl group which is substituted or unsubstituted with a halogen atom; a halogen atom; C1-C10 alkyl group; or aralkyl group which is substituted or unsubstituted with C2-C9 alkoxy group.
