Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Effects of tert-dodecanethiol (tertiododecylmercaptan) on soil macroorganisms was assayed by using the OECD 222 earthworm (Eisenia fetida) reproduction inhibition test. No effects on adult growth were recorded for an exposure duration of 4 weeks. No effects on reproduction (number of offsprings) was observed at the end of exposure period, 56 days, up to 100 mg tertiododecylmercaptan/kg dw. However, no measurements of test substance were made and as the test substance is volatile the OECD Guideline does not recommend the test for such cases. The study cannot be considered valid for these reasons.
The test substance is a synthetic chain tranfert agent consumed in the process and effluents are controlled. It is also volatile so any trace residues of substance which are not eliminated would be rapidly lost to air. Thus it is not considered necessary to perform further terrestrial studies beyond the existing reprotoxicity study on Eisenia.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.
