The Scientific Committee on Consumer Safety (SCCS) has concluded that current clinical data indicates that the concentration of 100 ppm of Methylisothiazolinone in cosmetic products is not safe for the consumer.
Methylisothiazolinone [CAS# 2682-20-4] a.k.a MIT
For leave-on cosmetic products (including ‘wet wipes’), no safe concentrations of Methylisothiazolinone have been adequately demonstrated. The SCCS concluded that it is important to address the increased incidence of allergies induced by Methylisothiazolinone and this substance should be banned in leave-on products. As a result, Annex V (list of preservatives allowed in cosmetic products) to the CPR has been amended accordingly, replacing entry 57.
From 12th February 2017 only products compliant with the regulations may be placed on the market.
