Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The chemical oxygen demand and biochemical oxygen demand of the Taicros-TMT has been determined in two studies according to national guidelines. However, no elevated oxygen consumption could be measured in the studies.
Biodegradation has also been investigated of the source substance (TMT, CAS 17766 -26 -6)) in a GLP-study using domestic activated sludge as inoculum. This study has been carried out with TMT 15 according to OECD guideline 302 B. Under the test conditions, no biodegradation of the substance was observed. In accordance to the results of the study, which have been considered in an analogous read-across approach, readily biodegradation of the registered test substance is not expected.
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.
