Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Not readily biodegradable: 51.5%  (CO2 evolution) in 28 days (OECD 301B)

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable, not fulfilling specific criteria

Additional information

One study investigating the ready biodegradability of 1,2-Benzenedicarboxylic acid, di-C16-18-alkyl esters (CAS No. 90193-76-3) is available. The study was conducted according to OECD guideline 301B under GLP conditions using non-adapted activated sludge as inoculum (Desmares-Koopmans, 2010). After 28 days of exposure, the test substance reached a biodegradation of 51.5 % and therefore, does not meet the criterion for ready biodegradability (> 60 % biodegradation on day 28), although it shows moderate biodegradability.
