Amendments to the list of allowed preservatives in Europe – Methylchloroisothiazolinone (and) Methylisothiazolinone, Methylisothiazolinone

The European Commission Regulation (EU) No. 1003/ 2014 of September 2014 amended Annex V of the EU Cosmetics Regulation with respect to the use of methylisothiazolinone and of the mixture methylisothiazolinone (and) methylchloroisothiazolinone in cosmetic products commercialized in Europe.

The mixture methylchloroisothiazolinone (and) methylisothiazoline has been banned from leave-on products, to reduce the skin sensitisation/ allergy incidents.The Scientific Committee for Consumer Safety has, however, concluded that the previously-approved maximum concentration of 0.0015% of a mixture in the ratio 3:1 of methylchloroisothiazolinone (and) methylisothiazolinone) is still safe for use in all rinse-off cosmetics.



The maximum allowed concentration of methylisothiazolinone remains 0.01%, nonetheless it has been established that the use of methylchloroisothiazolinone (and) methylisothiazolinone is incompatible with the use of methylisothiazolinone alone in the same products as it would affect the 3:1 ration agreed upon precedently



The deadline for making available on the market new compliant products was the 16th of July 2015, while those already marketed can still be sold until the 16th of April 2016.
