Description of key information

The reaction products of 1-decene, 1-dodecene and 1-octene, hydrogenated has been demonstrated to be readily biodegradable in the OECD 301 test and therefore would be expected to be rapidly biodegraded in the environment including sediment and surface water.   Therefore, sufficient data are available to assess the biodegradability potential of the test substance in sediment and surface water.  The reaction products of 1-decene, 1-dodecene, 1-octene, hydrogenated is expected to be rapidly biodegraded in these compartments under simulated conditions (i.e., wastewater treatment) and is not expected to be persistent. 

Key value for chemical safety assessment

Additional information

In accord with Column 2 of Annex IX, neither biodegradation testing nor simulation testing in sediment or surface water needs to be conducted because the test material is readily biodegradable.   Sufficient data are available to assess the biodegradability potential of the test substance in sediment and surface water.  As pointed out in the REACH guidance document, Chapter R7b, pg. 161-163, the simulation testing in sediment or surface water will provide little additional information since rapid mineralization in the environment is assumed.
