Description of key information
A hydrolysis study was performed on vinyl chloroacetate (VCA) in accordance with the OECD Testing Guideline 111. At pH 4 the half-life of VCA was 3.92 hours, whereas at pH 7 the half-life of the substance was 1.22 hours. A trend was observed indicating that the half-life decreases when the pH increases. Chloroacetic acid (CAS 79-11-8 / EC 201-178-4) and acetaldehyde (CAS 75-07-0 / EC 200-836-8) were identified as the main degradation products of VCA.
Considering that VCA degrades rapidly in water, the environmental fate and behaviour of the substance is expected to be driven by its main degradation products. Therefore the environmental fate and behaviour of VCA was determined using available data on acetaldehyde and chloroacetic acid.
It is not technically possible to determine the partition coefficient of VCA due the substance being hydrotycally instable in water. Therefore the partition coefficient of its degradation products acetaldehyde and chloroacetic acid was considered. The Log Kow of acetaldehyde and chloroacetic acid were found to be 0.63 and 0.22 respectively. These values indicate that these substances are not expected to bioaccumulate and that have a low potential for adsorption.
An assessment of the ready biodegradability of VCA was performed based on the ready biodegradability of its degradation products. Available experimental data on acetaldehyde and chloroacetic acid indicated that both substances were ready biodegradable. It was therefore concluded that VCA is expected to be ready biodegradable.
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.
