Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

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.
