PURPOSE:To provide the title low toxic agent having excellent moldproof effects on a wide variety of molds, comprising a combination of a specific quaternary ammonium compound with methyl 2-benzimidazolyl carbamate. CONSTITUTION:The objective moldproof agent which comprises a combination of (A) a quaternary ammonium compound of formula I (R1 to R4 are each chain hydrocarbon; one or two of them being of >=8C; X is halogen) (e.g. dioctyl dimethylammonium chloride, didecyl dimethylammonium chloride) with (B) methyl 2-benzimixazolyl carbamate of formula II. The weight ratio of A/B is (10:1) to (1:10), pref. (5:1) to (1:5). The level of the present agent at ca.1-1000 ppm gives a favorable mold proof effect. |
