Additional information
Since no studies investigating the ready biodegradability of tetradecyl oleate (CAS 22393-85-7) are available for this endpoint, in accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 a read across to the structurally related category member docosyl docosanoate (CAS 17671-27-1) was conducted. The read-across substance is representative to evaluate the biodegradation of dodecyl oleate. Docosyl docosanoate is characterized by a longer fatty acid chain length (C22) and a longer fatty alcohol chain length (C22) and can be used for read-across as a worst case approach since the chain length of the fatty alcohol and the fatty acid are the determining factor for biodegradation.
The study with the read-across substance docosyl docosanoate was performed according to OECD 301C (GLP) under aerobic conditions using a mixture of activated sludge from STP with freshwater from rivers and lakes, marine water and marine sediment as inoculum with a test substance concentration of 100 mg/L (Ministry of Economy, Trade and Industry, Japan, 1992). A biodegradation of 75.3% (BOD) was observed after 28 d. Since the substance reached the pass level for OECD 301C (biodegradation is > 60% after 28 d, no 10-day window required) docosyl docosanoate is readily biodegradable according to the OECD criteria.
Based on the results from one structurally related read-across substance (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) it can be concluded that tetradecyl oleate is readily biodegradable according to the OECD criteria.
