Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The bioconcentration potential of the reaction mass constituents in BADGE MXDA adduct have been assessed using a QSAR algorithm as described by Dimitrov et al (2005) and implemented in OASIS CATALOGIC. The QSAR modell fullfills the OECD criteria for regulatory acceptance. The model estimates steady state whole fish bioconcentration factor (BCF) based on a maximum BCF and mitigating factors that reduce the BCF.

Structural analogues identified from the training set have been processed parallel to the unknown. The unknowns are within the parametric domain of the model however within less than 50% of the structural domain as defined by first neighbour atom centred fragments.


Assuming that the prediction falls within the range of accurate predictions as defined by the developer the following BCF are calculated for the reaction mass BAGE MXDA adduct constituents:




log BCFcalc

[(mg/kg w.w.) /(mg/L)]



BAGE MXDA adduct constituents



0.68 ± 0.75


Based on a decision rule published by Dimitrov et al (2005), the reaction mass of BADGE MXDA are not bioaccumulative with high confidence.
