Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Long-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Long-term studies on invertebrates are not available. A long-term test is not required as no unacceptable effects has been detected in the risk assessment (risk characterization ratios <1).
Key value for chemical safety assessment
Additional information
According to column 2 in Annex IX of Regulation (EC) 1907/2006, long-term toxicity tests with aquatic organisms are not needed if the outcome of the chemical safety assessment indicates no unacceptable effects on aquatic organisms. In a first step, the PNEC for the aquatic environment is derived on short-term toxicity.
The risk for the aquatic compartment being exposed to N-butyl-2,2,6,6-tetramethylpiperidin-4-amine (N-butyl TAD) is acceptable as the risk characterization ratios are below 1. Therefore, further tests are not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
