To prevent mould infestation, preservatives are used in wall paints, such as emulsion paints. Isothiazolinones like 2-methyl-4-isothiazolin3-on (MIT) and 5-chloro-2-methyl-4-isothiazolin (CIT) are often used for this purpose.
The law permits the use of preservatives in emulsion paints to a certain extent. However, preservatives such as isothiazolinones can cause allergic reactions such as skin eczema in sensitised people. MIT and CIT are among the most common contact allergens as they can lead to severe skin and mucous membrane irritations.
Safety and quality are crucial for consumer confidence in a product and consequently for its market success. Our experts at WESSLING quickly and reliably analyse wall paints for preservatives using state-of-the-art technology in our laboratories. In addition, our test chamber analyses enable our experts to make precise statements about the emission behaviour of the wall paints within a short period of time.
