Description of key information
Additional information
From the two available guideline studies (modified Sturm test (OECD 301B) and STP simulation test (OECD 303A)) it can be concluded that CHPTAC is not readily biodegradable. However, the removal rate constant calculated from the STP simulation test (0.065h-1) is close to removal rate for inherently degradable substance (ESR Risk Assessment Report, EC, 2007), according to the criteria set in REACH Technical Guidance Chapter R16.
In other, non-standard tests some removal of CHPTAC has been observed.
The conclusion of the ESR Risk Assessment for CHPTAC was that the substance could be considered "inherently biodegradable not meeting specific criteria".
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.
