PURPOSE: A synergistic combination of selectively microbicidal compositions is provided to strengthen a microbicidal effect.CONSTITUTION: A synergistic microbicidal composition contains: a mixture of 5-chloro-2-methyl-4-isothiazoline-3-one and 2-methyl-4-isothiazoline-3-one and a synergistic mixture of caprylic acid, glycerol monolaurate, glyceryl monodicarylate, glyceryl caprate, propylene glycol caprylate, propylene glycol monoraurate, or lauric arginate compounds. A synergistic microbicidal composition contains: 2-methyl-4-isothiazoline-3-one and a synergistic mixture of caprylic acid, glycerol monolaurate, glyceryl monodicarylate, glyceryl caprate, propylene glycol caprylate, propylene glycol monoraurate, or lauric arginate compounds. A synergistic microbicidal composition contains 1,2-benzisothiazoline-3-one and a synergistic mixture of caprylic acid, glycerol monolaurate, glyceryl monodicarylate, glyceryl caprate, propylene glycol caprylate, propylene glycol monoraurate, or lauric arginate compounds.COPYRIGHT KIPO 2012본 발명은 제 2 살미생물제 또는 제제 성분 또는 원료와 배합된 선택 살미생물제의 상승적 배합물에 관한 것이다. 이 배합물은 개별 성분들의 조합으로부터 예측되는 것보다 뛰어난 효능을 나타낸다. 상기 배합물은 (a) 5-클로로-2-메틸-4-이소티아졸린-3-온 + 2-메틸-4-이소티아졸린-3-온 (b) 메틸-4-이소티아졸린-3-온 또는 (c) 1,2-벤즈이소티아졸린-3-온과 하나 이상의 기타 각종 화합물의 혼합물을 포함한다.
