The invention relates to compounds from the groups of (A) electrophiles, (B) nucleophiles, (C) alkylating agents, (D) antioxidants and (E) oxidizing agents as odor preventatives for reducing so-called ghost odor which is induced by 2-methyl-4-isothiazolin-3-one and/or octyl-4-isothiazolin-3-one. The invention further relates to biocide compositions which comprise 2-methyl-4-isothiazolin-3-one and/or octyl-4-isothiazolin-3-one and also one or more odor preventatives, and to the use of odor preventatives for preventing ghost odor.
Biocide Compositions Comprising 3-Methylisothiazolin-3-One And A Haloalkyl Sulphone
The invention relates to a biocide composition comprising, as active microbicidal components, 2-methylisothiazolin-3-one and also one or more haloalkyl sulphones, said composition being outstandingly suitable as an industrial preservative for protecting industrial products. The invention further relates to the use of haloalkyl sulphones as an additive for reducing “emissions” from compositions containing 2-methylisothiazolin-3-one.
