Description of key information
No experimental bioaccumulation data are available for MDI category substances. Tier 1 BCF screening calculations have been performed using the QSAR BCFBAF v2.01 (US EPA 2010). Representative components of the three substance being registered at >10 tpa have predicted BCF values <2000 L/kg w.w, indicating that these substances are not bioaccumulative.
Additionally, MDI category substances only occur in a grease base and, in realistic use scenarios, the formulated greases are specifically designed to minimise leaching of the thickener. The isolated thickeners are estimated to have a water solubility of less than 0.01 mg/L and have high log octanol-water partition coefficients. On this basis, MDI category substances are expected to reside within the grease base oil matrix and hence are not anticipated to be bioaccessible.
Key value for chemical safety assessment
