Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A 14-day LC50 value of >1000 mg/kg dry weight and a NOEC of ≥1000 mg/kg dry weight have been determined for the effects of the test substance on mortality of Eisenia foetida.
Further testing for toxicity to terrestrial organisms is not considered necessary because:
- The substance hydrolyses very rapidly and its hydrolysis product has a log KOW <3, therefore, partitioning to the terrestrial compartment is expected to be minimal.
- The short-term toxicity data available with this substance indicates that it is of low short-term toxicity to terrestrial organisms.
- PNECsoil has been calculated from PNECfreshwater on the basis of the equilibrium partitioning method; the risk characterisation ratio (RCR) based on PNECsoil is <1.
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.
