Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 soil: simulation testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

Further biodegradation testing, including biodegradation simulation testing in soil, is waived, in accordance with Regulation (EC) No.1907/2006, Annexes VIII and IX, Column 2.

Key value for chemical safety assessment

Additional information

According to Regulation (EC) No.1907/2006, Annexes VIII and IX, Column 2, further biodegradation testing, including testing for ultimate biodegradation in soil, need not be conducted if the substance is readily biodegradable, or if direct and indirect exposure to soil is unlikely. The substance was shown to be readily biodegradable. The experimentally-determined Koc for tetrapropenyl succinic anhydride is 825, from read-across based on a grouping of substances (category approach); this value falls within the range of Kocvalues of 500-1000, below which substances are unlikely to adsorb to soil. The chemical safety assessment did not indicate the need to investigate the degradation of the substance; the risk characterisation ratios for sediment are below one. Therefore, in accordance with Annex I, the risks are considered to be controlled. Therefore, simulation testing in soil is not indicated.
