MI Free is a resource for information about allergy to the preservative methylisothiazolinone (MI) and its relatives, such as methylchloroisothiazolinone (MCI), which are found widely in cosmetics, toiletries, household cleaning products and other domestic products such as paints.
Increasing numbers of consumers worldwide are developing serious and debilitating allergies to these ‘isothiazolinone’ preservatives, and the epidemic shows little sign of slowing down.
Those with allergy to MI often struggle to find what they need – such as lists of safe products, how to obtain a medical diagnosis or help with their problem, and information on the labelling of isothiazolinone preservatives on consumer products. This site aims to answer those questions.
