A method of protecting 3-isothiazolones of the formula: (see formula I) wherein Y is (C1-C18)alkyl or (C3-C12cycloalkyl each optionally substituted with one or more of hydroxy, halo, cyano, alkylamino, dialkylamino, arylamino, carboxy, carbalkoxy, alkoxy, aryloxy, alkylthio, arylthio, haloalkoxy, cycloalkylamino, carbamoxy, or isothiazolonyl; an unsubstituted or halo-substituted (C2-C8) alkenyl or alkynyl; a (C7-C10)aralkyl optionally substituted with one or more of halogen, (C1C4)alkyl or (C1-C4) alkoxy; or an aryl optionally substituted with one or more of halogen, nitro, (C1-C4)alkyl, (C1-C4)alkyl-acylamino, carb(C1-C4)alkoxy or sulfamyl; and R and R1 is each independently H, halogen (C1-C4) alkyl, or (C4-C8) cycloalkyl, or are joined together to form a phenyl; comprising incorporating therewith an effective amount of a sulpher-containing compound, or salt thereof, capable of reversibly forming an adduct with said isothiazolone.
