Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Due to the low solubility of octacos-1-ene experimental data are not available and have not been proposed. Read across from tetradec-1-ene and hexadec-1-ene indicate that effects on invertebrates may be observed. However, the predicted toxicity of octacos-1-ene is above its limit of solubility so toxicity is not expected.
Key value for chemical safety assessment
Additional information
Experimental data are not available for octacos-1 -ene. In the absence of data for octacos-1 -ene, data have been read across from category members with a lower carbon number.
Drottar and Swigert (1995) and Whale and Cheesman (1995) tested the toxicity of tetradec-1-ene and Douglas and Halls (1993) and Whale and Cheesman (1995) tested the toxicity of hexadec-1-ene to aquatic invertebrates in OECD Guideline 202 tests. 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 tests were conducted as limit tests with a single exposure concentration of 1000 mg/l WAF. Effect levels up to 85% were observed after 48 hours.
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.
