Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

MDI substances only occur in a base oil grease and, in realistic use scenarios, the formulated greases are specifically designed to minimise leaching of the thickener. The isolated thickeners are estimated to have water solubilities of less than 0.01 mg/L, vapour pressures of less than 10 E-10 Pa and high log octanol-water partition coefficients. On the basis of the physical-chemical properties and bioaccessibility studies, MDI substances are expected to reside within the grease base oil matrix. As such, MDI substances are not expected to partition to water, soil or air and hence are not anticipated to be accessible in the environment.
