PURPOSE:To provide an agent having aging stability by adding a propanol derivative to a system containing 1,2-benzisothiazolin-3-one and an isothiazolone derivative known as a bacteria-proofing and mildew-proofing agent for industrial use. CONSTITUTION:A liquid bacteria-proofing and mildew-proofing agent containing a bacteria-proofing and mildew-proofing component stabilized to aging is produced by adding a propanol derivative of formula III (R1 to R3 are H, halogen, alkyl, OH, cyano, thiol, nitro, carboxyl, amino or sulfone) (e.g. n-propanol or isopropanol) to a liquid preparation containing an isothiazolone derivative of formula I (X is H or halogen; Y is lower alkyl) or its complex (e.g. 5-chloro-2- methyl-4-isothiazolin-3-one) together with 1,2-benzisothiazolin-3-one of formula II or its salt. |
