Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
On the basis of read across, acute toxicity is not expected at the limit of solubilty.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 1 000 mg/L
Additional information
Experimental data are not available for hexacos-1-ene. In the absence of data for hexacos-1-ene, data have been read across from category members with a lower carbon number.
Drottar and Swigert (1995) tested the toxicity of tetradec-1-ene and Douglas and Halls (1993) tested the toxicity of hexadec-1-ene to Oncorhynchus mykiss in an OECD Guideline 203 test. Due to the low solubility of the test substances test organisms were exposed to water accommodated fractions (WAF) and exposure concentrations were expressed as a loading rate. The test was conducted as a limit test with a single exposure concentration of 1000 mg/l WAF. No mortality was observed at this loading rate, so the 96 hour LL50 was >1000 mg/l WAF.
Based on read across, these results indicate that we would not expect hexacos-1-ene to exhibit acute toxicity to fish at exposure concentrations up to its limit of solubility.
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.
