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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Name:
- Fatty acids, C18-unsatd., dimers, oligomeric reaction products with 1-chloro-2,3-epoxypropane
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- Fatty acids, C18-unsatd., dimers, oligomeric reaction products with 1-chloro-2,3-epoxypropane
- Reference substance:
- Fatty acids, C18-unsatd., dimers, oligomeric reaction products with 1-chloro-2,3-epoxypropane
- Reference substance:
- Fatty acids, C18-unsatd., dimers, oligomeric reaction products with 1-chloro-2,3-epoxypropane
- Reference substance:
- Fatty acids, C18-unsatd., dimers, oligomeric reaction products with 1-chloro-2,3-epoxypropane
- PBT status:
- further information relevant for the PBT assessment is necessary
- Justification:
Persistence
The test substance is not readily biodegradable therefore therefore on the basis of the screening criteria it must be considered that the substance could possess P or vP properties, although no data are currently available to confirm this conclusion.
Bioaccumulation
Experimentally derived Log Kow was found to be 6.5 therefore on the basis of the screening criteria it must be considered that the substance could possess B or vB properties, although no data are currently available to confirm this conclusion.
Toxicity
For aquatic toxicity long term toxicity data not available. No toxicity was observed at all trophic levels for short term aquatic studies.
No available data for carcinogenicity.
Mutagenicity classification remains inconclusive a testing proposal for an in-vivo study has been included under section 7.6.2.
Adverse effects were seen in the reproductive developmental screening study therefore the test substance is classified Toxic to reproduction Category 1B.
The test substance is not classified for specific target organ toxicity after repeated exposure. Effects were only seen in reproductive organs therefore classified for reproductive toxicity only. Based on the reproductive toxicity classification it can be confirmed the substance is toxic.
Conclusion
The overall PBT assessment cannot be concluded as only the Toxicity data are sufficient to conclude the toxicity criteria. Persistence and Bioaccumulation criteria cannot be concluded based on screening criteria therefore further information is necessary to finalise the PBT status. We will update the dossier as soon further information information becomes available on the Persistence and Bioaccumulation endpoints.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
