Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests:

Normal paraffins in the C9 to C14 Aliphatics category (<2% aromatics) are readily biodegradable, exhibiting 77 to 83% biodegradation in 28 days based on oxygen consumption and meeting the 10-day window.

Moreover, "Hydrocarbons, C14-C20, aliphatics (≤2% aromatics)" were found to be readily biodegradable (biodegradation > 60% ThOD) in an OECD 306 ready biodegradability test.

Therefore, the substance Paraffins (petroleum), normal C>10 is considered readily biodegradable and no further biodegradation studies are deemed necessary.
