Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bioaccumulation Estimates (BCFBAF v3.01):

Log BCF from regression-based method = 1.850 (BCF = 70.79 L/kg wet-wt)

Log Biotransformation Half-life (HL) = 1.4797 days (HL = 30.18 days)

Bio Half-life normalised to 10 g fish at 15 °C

Log BCF Arnot-Gobas method (upper trophic) = 1.622 (BCF = 41.91 L/kg wet-wt)

Log BAF Arnot-Gobas method (upper trophic) = 4.484 (BAF = 3.046e+004 L/kg wet-wt)

log Kow used: 9.13 (estimated)

Conclusions:
BCFBAF v3.01 was used for the bioaccumulation calculation. The log BCF was 1.622. The BCF was determined to be 41.91 based on the Arnot-Gobas method (upper trophic). This indicates a low potential for the test substances to bioaccumulate.

log Kow used: 10.60 (estimated)

Validity criteria fulfilled:
not applicable
Conclusions:
BCFBAF v3.01 was used for the bioaccumulation calculation. The log BCF is 0.622. The BCF was determined to be 4.191 based on the Arnot-Gobas method (upper trophic). This indicates a low potential for the test substances to bioaccumulate.

Description of key information

No study on bioaccumulation is available with the substance. Therefore, the bioaccumulation profile of substance was calculated using BCFBAF v3.01. The log BCF was 0.622-1.622.  The BCF was determined to be 4.19-41.91 based on the  Arnot-Gobas method (upper trophic). This indicates a low potential for the test substances to bioaccumulate.

Key value for chemical safety assessment

Additional information

The bioaccumulation profile of substance was calculated using EPIWIN (BCFBAF v3.01). Based on these calculations, the substance has a low potential to bioaccumulate.
