Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is quickly eliminated from both water body and sediment, with hydrolysis to the free acid and further biodegradation of this hydrolysis product (DT50 0.4 and 3.2 days at 12 °C based on data obtained from water/sediment systems from Europe and the US). Anaerobic degradation of the parent substance is also fast (DT50 of 1.3 d in water/sediment system and 0.042 d in soil). Considering the total system, the substance and its metabolites will be degraded in the aquatic environment. The test item’s hydrolysis product, its free acid, is weakly adsorbed to the sediment, but the overall degradation is fast, also demonstrated by the formation of carbon dioxide, especially in aerobic systems, and metabolites in water-sediment systems. An aerobic soil environment will have a significant contribution to the overall degradation of the substance.
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.
