Preservatives used in coatings and adhesives have traditionally been combination products based on, among other substances, the effective and active substance MIT (Methylisothiazolinone). MIT has also been used in cosmetics, which has contributed to a large group of people being sensibilised to contact with MIT, even in small dosages.
After several incidents with severe allergic reactions related to paints, the legislation on MIT is being revised. Most likely, the outcome of this will be that MIT in large concentrations in consumer products will no longer be allowed by 2020 and onwards.
In collaboration with Lonza, Brenntag can advise and help you identify functioning preservatives that are usable in the long term. One alternative is the new product from Lonza called Proxel Spektra. The products is based on a combination of BIT, Sodium Pyrothione and a unique stabilizer and reduces the risk of yellowing/discolouring as well as increasing the effectiveness of the active substances.
