Methylisothiazolinone (MI) belongs to a compound group ‘Isothiazolinones’. Though it is a widely used substance to preserve the products, the use of Methylisothiazolinone is controversial in this cosmetic industry because of the increasing trend of allergic reactions with the use of cosmetics containing MI. It might be commonly found in different varieties of cosmetics products including shaving and after-shave products, lotions, shampoo and shower gel, nail product, suntan preparations, make-up cosmetics etc.
