Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bioaccumulation: aquatic/sediment: low potential for bioaccumulation

Key value for chemical safety assessment

Additional information

The substance hydrolyses rapidly in contact with water to substances which have low log Kow values (< 3) and thus have low potential for bioaccumulation, and the requirement for testing is waived. The parent substance itself also has a log Kow value < 3.


 


This conclusion is supported by BCF values of ≤ 3.5 (nominal concentration 5 mg/L) and ≤ 34 (nominal concentration 0.5 mg/L)  in common carp (Cyprinus carpio) determined in a study conducted similar to an appropriate test protocol, and in compliance with GLP. The study is considered to be reliable with restrictions; the restrictions are that the use of a dispersant is not considered to be necessary for the test substance. The study report is only available in Japanese, and therefore limited details are available.
