STABILIZED ISOTHIAZOLONE COMPOSITION

摘要

PURPOSE:To provide the subject composition having an excellent stabilization effect for the prevention of the decomposition thereof and capable of being stably stored over a long period by adding an alkylene carbonate or its mixture with polypropylene glycol as a stabilizer to an isothiazolone compound. CONSTITUTION:A stabilized isothiazolone composition comprises an isothiazolone compound (especially 5-chloro-2-methyl-4-isothiazoline-3-one or 2-methyl-4- isothiazoline-3-one) and an alkylene carbonate preferably in a weight ratio of approximately 1/(1-9). Also, a stabilized isothiazolone composition comprises the isothiazolone compound and a preferably 1:0-1:9 weight ratio mixture of the alkylene carbonate and a polyalkylene glycol preferably in a weight ratio of approximately 1/(1-9). The composition can be readily and effectively applied to all uses because of containing no poisonous substance.
