EC number: 273-110-1 | CAS number: 68938-03-4 The complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isononanal. It consists predominantly of C6 olefins and paraffins and C9 alcohols and aldehydes and boiling in the range of approximately 110°C to 202°C (230°F to 396°F).

Additional information
Oxooil LS9 was tested in an acute toxicity test with daphnids (Daphnia magna) under static conditions according to the guideline OECD 202, April 2004 (Acute Immobilisation test for Daphnia). Groups of twenty daphnids (2 replicates of 10 animals) were exposed to Water Accommodated Fractions (WAFs) of the test substance over a range of nominal loading rates of 1.0, 1.8, 3.2, 5.6, 10, 18, 32, 56 and 100 mg/l for 48 hours at a temperature of 21°C to 22ºC under static test conditions. The number of immobilised Daphnia was recorded after 24 and 48 hours. The 48-Hour EC50 for the test material to Daphnia magna was 12 mg/l nominal loading rate WAF, with 95% confidence limits of 11 - 13 mg/l loading rate WAF. The No Observed Effect Concentration was 5.6 mg/l nominal loading rate WAF.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
