Abstract

The invention relates to a liquid preparation containing 1,2-benzoisothiazoline-3-one (BIT) and amines and optionally containing additional solvents and common additives, and containing as amine one or more amines having the general formula ##STR1## wherein R represents a straight-chained or branched alkyl or alkylene radical having 10 to 14 C atoms; n+m has a value of 4 to 12 and neither n nor m can be zero. The liquid composition, in an amount of at least 0.05 to 0.3% (by weight), can be used in products which contain water or can be diluted with water such as dispersions of synthetic materials, emulsion paints, adhesives, paper-coating materials, textile softening agents, sizing agents, surfactants, detergents, cleaning and polishing agents, spinning baths, coolants or metal working fluids, leather auxiliaries, and silicone and bitumen emulsions, as agent against material destruction caused by microbes.
