General description

1,2-Benzisothiazol-3(2H)-one can be synthesized by reacting 2-mercaptobenzoic acid with diphenyl phosphoryl azide.^[1]

Benzisothiazolinone (BIT) is a widely used biocide and belongs to the group of isothiazolinones.

Detailed description

Usage

Benzisothiazolinone has a microbicide and a fungicide mode of action. It is widely used as a preservative, for example in:

·         emulsion paints, caulks, varnishes, adhesives, inks, and photographic processing solutions

·         home cleaning and car care products; laundry detergents, stain removers and fabric softeners;

·         industrial settings, for example in textile spin-finish solutions, leather processing solutions, preservation of fresh animal hides and skins

·         agriculture in pesticide formulations

·         gas and oil drilling in muds and packer fluids preservation.^[2]:iv

In paints, it is commonly used alone or as a mixture with methylisothiazolinone. Typical concentrations in products are 200–400 ppmdepending on the application area and the combination with other biocides. According to a study in Switzerland, 19% of the paints, varnishes and coatings contained BIT in 2000. The fraction in adhesives, sealants, plasters and fillers was shown at that time as 25%.^[3]A later study in 2014 shows a dramatic rise in usage, to 95.8% of house paints.
