Isothiazolinones are synthetic preservatives used in a range of products including cleaning, laundry and personal care. They are known as sensitizers^iv, which have been linked to allergic contact dermatitis^v. Because of these health concerns, the European Parliament and the Council on Cosmetic Products have proposed to restrict isothiazolinone use to rinse-off products only^vi ( i.e. products such as body and hand washes, and not leave-on products such as moisturisers).
