Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
bioaccumulation in aquatic species: fish
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Description of key information

The log Kow of 4.7 of the substance would indicate that bioaccumulation should be determined. But hydrolysis results show that half-lives are < 12h at test conditions. Hence, the likelihood of bioaccumulation is greatly reduced (REACH guidance document R.7c, section R.7.10.3.4, p. 26) focus should lie on hydrolysis products instead of the parent substance. Log Kow value of the hydrolysis product is 2.44 and therefore a BCF study can be waived.

Key value for chemical safety assessment
