An aqueous isothiazolone formulation useful for antiseptic or antifungal treatment of various synthetic polymeric emulsions, which comprises (a) a specific isothiazolone compound, (b) water or an aqueous solvent and (c) a specific nitrobromo or cyanobromo compound.

Aqueous isothiazolone formulation

A microbicidal/microbistatic synergistic composition for industrial use comprising a specific nitrobromopropane derivative and 4,5-dichloro-1,2-dithiol-3-one and an industrial method of killing or inhibiting the growth of microorganisms using the same compounds, which are useful of microbicidal/microbistatic treatment in various industrial media.

Microbicidal/microbiostatic composition for industrial use

A water-soluble antiseptic or antifungal composition containing 2-(thiocyanomethylthio)benzothiazole as the active ingredient, a polyoxyalkylene styrylphenyl ether phosphoric acid ester, or alkali metal salt thereof as a surfactant and an organic solvent. The composition forms a clear solution which is stable for long periods of time and which can be diluted with water.

Water-soluble antiseptic or antifungal composition

A microbicidal/microbistatic synergistic composition for industrial use comprising a specific nitrobromopropane derivative and 2,2-dibromo-3-nitrilopropionamide and an industrial method of killing or inhibiting the growth of microorganisms using the same compounds, which are useful for microbicidal/microbistatic treatment in various industrial media.

Microbicidal/microbistatic composition

A composition comprising 2-(thiocyanomethylthio)benzothiazole and 3-iodo-2-propinyl-N-butylcarbamate. The composition can be useful as a microbicidal preservative to prevent deterioration of raw materials such as dyes, pastes, lumber, leather, textiles and pulp caused by microorganisms.

Microbicidal preservative composition

A composition comprising a quaternary ammonium compound and 2-(thiocyanomethylthio)benzothiazole. The composition can be useful as a microbicide and preservative for preventing the deterioration of various types of industrial raw materials and products by inhibiting the growth of microorganisms.

Quaternary ammonium and benzothiazole microbicidal preservative

An easily dispersible polymer composition which comprises a powder of a water soluble polymer having floculating property and a sodium sulfate hydrate, and optionally a magnesium sulfate hydrate and a hydroscopic agent and which shows a high degree of granularity and free-fluidity.
