What is it  used for ?
MIT is used to protect products from contamination by potentially pathogenic microbes (fungi and bacteria). Its use allows to ensure the product is safe for consumers.
What is MIT  ?
Methylisothiazolinone or MIT is a preservative used in many consumer goods including cosmetic products, to preserve product quality and ensure consumer safety by preventing the growth of microbes.
To identify it in our products, take a look at the ingredients list on packaging. It can be found under the name METHYLISOTHIAZOLINONE.
Where does it  come from ?
MIT is a synthetic ingredient.
Why and how  do we use it ?
Since 2017, we no longer sell leave-on products containing MIT.
We have decided to go beyond the regulation and to completely phase out MIT of our products, including rinse-off products.
Why is it  questioned ?
Following the controversy over parabens, MIT has been used increasingly as a preservative of cosmetic products. It was then accused of causing allergies and eczema.
- MIT can induce allergies for some people, when it stays in prolonged contact with the skin, such as when using leave-on products (i.e. products that do not rinse with water).
- Since the beginning of the 2000s with the increase of the presence of MIT in products, in particular leave-on cosmetic products, but also in several other types of consumer goods, cases of allergies to MIT have multiplied.
- For cosmetic products, this risk of allergy has only been confirmed for certain leave-on products that are not meant to be rinsed after use. As a result, a European regulation from July 2016 banned the use of MIT in leave-on products. Moreover, as early as 2013, the European Cosmetics Industry Association (Cosmetics Europe) had anticipated by asking its members to voluntarily cease the use of MIT in leave-on products.
- The use of MIT is limited to a concentration of 0.0015% in rinse-off products.
