Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, toxicity is not expected at the limit of solubilty.

Key value for chemical safety assessment

Additional information

Experimental data are not available for icos-1 -ene. In the absence of data for icos-1 -ene, data have been read across from category members with a lower carbon number.

Thompson and Swigert (1995) and Hudson (1999) tested the toxicity of tetradec-1 -ene and Douglas and Halls (1993) and Hudson (1999) tested the toxicity of hexadec-1 -ene to algae. 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 48 and 72 hour EL50 was >1000mg/l WAF.

These results indicate that icos-1 -ene is not expected to exhibit toxicity to algae at exposure concentrations up to its limit of solubility.
