BENZISOTHIAZOLINONE (BIT)

1,2-Benzisothiazol-3(2H)-one, also known as benzisothiazolone or proxel, belongs to the class of organic compounds known as benzothiazoles. These are organic compounds containing
 a benzene fused to a thiazole ring (a five-membered ring with four carbon atoms, one nitrogen atom and one sulfur atom). 1, 2-Benzisothiazol-3(2H)-one exists as a solid, slightly
 soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 1, 2-benzisothiazol-3(2H)-one is primarily located in the cytoplasm.
 1, 2-Benzisothiazol-3(2H)-one is a potentially toxic compound.

Benzo[d]isothiazol-3-one is an organic heterobicyclic compound based on a fused 1,2-thiazole and benzene bicyclic ring skeleton, with the S atom positioned adjacent to one of the positions of ring fusion. 
It has a role as a disinfectant, a platelet aggregation inhibitor, an environmental contaminant, a xenobiotic, a drug allergen and a sensitiser. It is an organonitrogen heterocyclic 
compound and an organic heterobicyclic compound.


Benzisothiazolinone has a microbicide and a fungicide mode of action. It is used as a preservative in emulsion paints, varnishes, adhesives, washing agents, fuels and in the papermaking
 process. In paints, it is commonly used as a mixture with methylisothiazolinone. Typical concentrations in products are 200–400 ppm depending 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 25%

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


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.
In paints, it is commonly used alone or as a mixture with methylisothiazolinone. Typical concentrations in products are 200–400 ppm depending 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%. A later study in 2014 shows a dramatic rise in usage, to 95.8% of house paints.

Given sufficient dose and duration, dermal exposure can produce skin sensitization and allergic contact dermatitis,and is classified as an irritant for skin and eyes.
Benzisothiazolinone has also been linked with Systemic Contact Dermatitis via airborne contact.
