A harmonised classification for MIT (methylisothiazolinone)
The adopted classification
The 13th Adaptation to Technical and Scientific Progress (ATP) n�2018/1480 has come into force and is mandatory since 1st May 2020. This harmonised classification was published in the CLP regulation update and has serious impacts on industries. This classification is applicable since June 2017. Among the impacted substances is methylisothiazolinone, or MIT, whose harmonised classification is as follows:

Implications for business
This means that if you have products requiring SDSs (Safety Data Sheets) and labels that comply with the CLP, regulation, you must update them with this new classification. During this update you must check the hazard classification of the product and the labelling elements.
This new hazard classification has an important impact on the hazard category - Skin sensitiser - H317. It defines an SCL (Specific Concentration Limit) for this hazard at 0.0015% or 15 ppm (parts per million). This results in a CEL of 0.0015% or 15 ppm (parts per million):
- If the MIT is at a concentration greater than or equal to 15 ppm, your product is classified as a skin sensitiser and must be labelled accordingly
- If the MIT is at a concentration between 1.5 ppm and 15 ppm (one tenth of the specific concentration limit) then the additional phrase EUH208 is mandatory on the label and in the SDS. In addition, if your product is not classified as hazardous, the phrase EUH210 also applies. The SDS must then be made available upon request.
Finally, as a result of this harmonised classification, an M factor of 10 has been defined (multiplication factor to increase the weight of toxic substances in the classification of mixtures). This has an impact on the hazard category "Dangerous for the aquatic environment - Chronic hazard": if the MIT is at a concentration superior or equal to 0.025 % or 250 ppm the product will be classified as dangerous for the environment. Your labels and SDSs will need to be updated accordingly.
This new harmonised classification may therefore have an impact on your SDSs and labels. EcoMundo can assist you in updating all your documents and in assessing the impact of this new classification on your products, if necessary.
Context: the uses of MIT
2-Methylisothiazol-3(2H)-one also known as methylisothiazolinone (MIT) CAS No: 2682-20-4 or EC No: 220-239-6 is a preservative used in paints, coatings, detergents or even cosmetics.
Its biocidal properties make it a very effective preservative. On the other hand, many studies have revealed that this preservative is allergenic even in very small quantities. That is why a harmonised classification specific to this substance has been proposed and accepted.
