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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence Assessment
After 28 days 86.6 % of the test substance had been degraded in a manometric respirometry test (OECD Guideline 301 F). Based on these results, the substance is ready biodegradable and therefore identified as not P/vP.
BioaccumulationAssessment
In the absence of a measured BCF value, the log KOWcan be used as a screening criterion for bioaccumulative potential (i. e. >4.5). As the log KOWof the substance is below 4.5, the B/vB criterion is not met. Therefore the substance is identified as not B/vB.
Toxicity Assessment
The acute effect information for all three trophic levels is much higher than the screening criterion of 0.1 mg/l. It can therefore be expected that vinyl chloride is not toxic towards aquatic organisms. The overall conclusions, based on the present available data, of the preliminary PBT assessment are that the (screening) criteria for PBT/vPvB are not met and that further testing in the scope of the final PBT assessment is not considered to be required.
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.
