Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
No measured data are available for long-term toxicity of TOS to fish. A data-waiver is considered to be appropriate for this endpoint on the following grounds:
- The results from the short-term tests with Crude Tall Oil (EC number 931-433-1) indicate that fish and invertebrates are similarly susceptible to the substance and algae are less susceptible. Reliable long-term invertebrates test data for Crude Tall Oil (EC number 931-433-1) are available and they show an absence of toxicity at a loading rate of 1 mg/L.
- Calculation of PNECs for the aquatic compartment will be based on data for the blocks of constituents rather than on data for the whole substance.
Testing for long-term toxicity to fish will therefore not contribute to the database that is required to complete the assessment of the substance.
Key value for chemical safety assessment
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.
