Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Due to the low solubility of hexacos-1-ene experimental data are not available and have not been proposed. Read across from tetradec-1-ene and hexadec-1-ene indicates that effects on invertebrates may be observed. However, the predicted toxicity of hexacos-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 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) 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. All the tests were conducted as limit tests with a single exposure concentration of 1000 mg/L WAF except for Douglas and Halls (1993) who created a stock solution of 1000 mg/L WAF which they then diluted to give diffenent exposure concentrations.WAF should be prepared by adding the appropriate amount of test substance to the test media, rather than by dilution. Therefore, only the results from the 1000 mg/L WAF are considered valid. Results from all four tests reported effect levels up to 85% were observed after 48 hours.
