Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The toxicity controls in the biodegradation tests proved that the test item was not toxic to the inoculum at concentrations far above the water solubility.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 22 mg/L
Additional information
In the biodegradation studies, the toxicity controls proved that AHTN was not toxic to the inoculum at concentrations far above the water solubility. The NOEC used in the Risk Assessment Report of AHTN was higher (> 30 mg/L), but the reported value here was the lowest concentration used in the biodegradation tests. For the purpose of deriving the PNEC (STP), this value has been taken forward.
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.
