Description of key information

On the basis of experimental data, supported by QSAR data, the MDI category members are not considered readily biodegradable. The limited degradation may be a result of the low predicted water solubilities of the category members reducing the concentration and bioavailable fraction for degradation by micro-organisms. MDI category members only occur in a grease base and, in realistic use scenarios, the formulated greases are specifically designed to minimise leaching of the thickener. As such, exposure to the isolated thickener is not expected to occur and biodegradation processes in water, sediment or soil are not considered to be relevant environmental fate processes.
