Key value for chemical safety assessment

Additional information

Concerning the bioaccumulation potential of 2,2'-dimethyl-4,4'-methylenebis(cyclohexylamin) a valid study was performed by NITE Japan (2002) according to OECD 305C (replaced); OECD 305-I (2012), with Cyprinus carpio as test species and using a flow-through procedure. This study was selected as key study. After 60 days, a max. BCF of < 60 was measured, indicating that the substance will not significantly bioaccumulate in organisms.

The experimental result is supported by calculated data (BASF SE, 2015). The BCF was calculated to be 15.29 L/kg; the substance is within the applicability domain of the estimation model (BCFBAF v3.01, submodel according to Meylan et al. 1997/1999; EPISuite v4.11).
