Benzisothiazolinone (BIT) is an organic chemical that is characterized by high antimicrobial activity. These properties predispose BIT to use in many industries as a preservative and biocide. Interestingly, this substance is effective against a wide range of microorganisms, including bacteria, yeasts and moulds, making it a very versatile ingredient in many types of products. In addition to its main name, BIT is also known by the names 1,2-benzisothiazol-3(2H)-one, 1,2-benzoisothiazolin-3-one, Benzoisothiazolin-3-one, IPX, Proxan, Proxel, Proxel PL, Nipakid BIT, Mergal BIT.
Benzisothiazolinone finds application in many products where it acts as a preservative and prevents the growth of undesirable microorganisms. It is commonly used in industrial and household cleaners, soaps, shampoos, air conditioners, or in the manufacture of paper and adhesives. Another important sector where BIT is used is the construction industry. It is a component of many paints, sealants, adhesive tapes, concrete mixes and other products. However, despite its usefulness, BIT has come under considerable criticism due to potential health risks. It can cause skin, eye and respiratory irritation with prolonged or repeated exposure. The substance is also included in the list of substances that can cause an allergic reaction.
