Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Information is available from reliable studies for all the required in vitro endpoints. The results of all the studies were in agreement.

Short description of key information:
In vitro:
Gene mutation (Bacterial reverse mutation assay / Ames test): negative with and without activation in all strains tested (OECD TG 471)
Cytogenicity in mammalian cells: negative in cultured human lymphocytes (OECD TG 473)
Mutagenicity in mammalian cells: negative in L5178Y cells (OECD TG 476)

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

The available information for the substance indicates that when tested in vitro, Crude Tall Oil (CAS number 8002 -26 -4) does not induce mutations in bacterial or mammalian cells, nor chromosome aberrations in mammalian cells. There is no justification from in vitro results for testing in vivo. Therefore it is considered that classification for mutagenicity is not required.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
