Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ecotoxicological information

Long-term toxicity to aquatic invertebrates

Administrative data

Endpoint:
long-term toxicity to aquatic invertebrates
Type of information:
experimental study planned
Justification for type of information:
No datum for long-term toxicity to aquatic invertebrates is available for the registered substance. In accordance with the Decision of the Board of Appeal in case A-011-2018, the REACh Annex IX, Section 9.1., Column 2 does not allow omitting the need to submit information on long-term toxicity to aquatic invertebrates under Column 1. Therefore, long-term toxicity to aquatic invertebrates testing is a standard information requirement under annex IX of REACh regulation EC 1907/2006. Therefore, an OECD 211 study is proposed and cannot be waived.
