Benzisothiazolinone is used in several cleaning products, including green cleaningones, such as laundry detergents, air fresheners, fabric softeners, stain removers, dish detergents, stainless steel cleaners, etc. It is used at a rate of 0.10% to 0.30% (by weight) when added to laundry and household cleaning products according to the EPA in the 2005 document, Registration Eligibility Decision (RED) for Benzisothiazoline-3-one. Also, it is important to point out that it is often used in many cleaning products in conjunction with methylisothiazolinone, a synthetic preservative with some health concerns.

Environmental Effects
This chemical quickly biodegrades and there is "minimal environmental exposure" according to the EPA in its 2005 review of the chemical. However, the EPA also notes that there is evidence for benzisothiazolinone being toxic to aquatic life when it is used in oil-recovery fluids. So, clearly some applications for this chemical really shouldn't be allowed.
