Hydrocarbons, C10-C12, isoalkanes, <2% aromatics, biodegraded to an extent of 31% after 28 days and 41% after 41 days in a test of ready biodegradability. In a subsequent study that used an acclimated inoculum, it biodegraded to an extent of 42% after 28 days and 48% after 41 days. This test substance can be considered inherently biodegradable. These data are used as read-across data to hydrocarbons, C11-C12, isoalkanes, <2% aromatics.

Hydrocarbons, C12-C14, isoalkanes, <2% aromatics biodegraded to an extent of 11% after 28 days in seawater that used the indigenous microorganisms in the seawater sample as a sole source of the inoculum. These data are used as read-across data to hydrocarbons, C11-C12, isoalkanes, <2% aromatics.
