Additional information

Short-term toxicity

A 72 h EC50 value of 98 mg/kg dw soil (1.3% organic carbon) has been determined for the effects of decanol (CAS 112 -30 -1) on population numbers of the nematode C. elegans.

No data is currently available with decanol branched and linear (CAS 90342-32-8), however data is available with the closely related substance decanol (CAS 112-30-1). It is possible to validly read-across data between the two substances, as outlined in the overall aquatic toxicity endpoint summary.

The study reflects the lowest reliable value that is available for this endpoint.

Long-term toxicity

In accordance with Column 2 of REACH Annex X, long-term toxicity testing with terrestrial invertebrates (required in Section 9.4.4) is not needed as the chemical safety assessment according to Annex I indicates that this is not necessary.

Moreover, considerable technical difficulties would be expected in the conduct of such a test, due to the very rapid biotic removal of the substance from the test system (based on experience in the long-term aquatic invertebrate study).
