- Endpoint:
- activated sludge respiration inhibition testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
VCA has been found to hydrolyse rapidly (t1/2 < 12 hrs) upon contact with water, to form two main degradation products: Chloroacetic acid (CAS 79-11-8 / EC 201-178-4) and Acetaldehyde (CAS 75-07-0 / EC 200-836-8). An expert assessment on the biodegradability of these degradation products concluded both substances are readily biodegradable based on existing literature.

Description of key information
In accordance with Annex VIII of REACH, the study does not need to be conducted because the substance hydrolyses rapidly on contact with water and the degradation products are found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of sewage treatment plant.

Additional information
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.
