Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE”, a simulation testing on ultimate degradation in surface water, the study does not need to be performed if the substance is ready biodegradable. Isobutyl alcohol is reagents used in the manufacture of O-isobutyl ethylthiocarbamate.Therefore, the Biodegradation in water of Isobutyl alcohol need to be considered in the assessment of O-isobutyl ethylthiocarbamate . The ready biodegradability of the substance was examined. After 28 days, approximately 74% of the test material was degraded.
The results suggest that Isobutyl alcohol is readily biodegradable and therefore O-isobutyl ethylthiocarbamate will be readily biodegradable and it is not expected to persist in the environment. As O-isobutyl ethylthiocarbamate is ready biodegradable a ready biodegradability study does not need to be conducted.
Therefore testing for Biodegradation in water screening tests does not need to be performed.
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.
