Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
A 21 day NOELR of ≥1 mg/L has been determined for the effects of the test substance on reproduction, growth and mortality of Daphnia magna. The result was obtained in a test conducted on the sample of CTO that showed the highest toxicity in the short-term tests with D. magna.
CTO is a UVCB substance and compositional information has been used in conjunction with validated QSARs to derive long-term No Observed Effect Concentrations (NOECs) for its constituent blocks. Calculation of PNECs for the aquatic compartment will be based on data for the constituent blocks rather than on data for the whole substance. Further testing for long-term toxicity to invertebrates will therefore not contribute to the database that is required to complete the assessment of the substance.

Additional information
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.
