Biodegradation in water: screening tests

The test substance Reaction product of adipic acid and sebacic acid and isotridecan-1 -ol was demonstrated to be readily biodegradable in an OECD 301B-test. In EPISuite-calculations it was also found that the components/isomers of these substances, including the diisotridecyl sebacate, are readily biodegradable. Addionally the read-across substances Diisotridecyl dodecanedioate and bis (2-ethylhexyl) adipate were in OECD-tests readily biodegradable. Therefore it is likely that the reaction product of adipic acid and sebacic acid and isotridecan-1 -ol including the components are readily biodegradable and not persistent.

 

Biodegradation in water and sediment: simulation tests

In accordance with column 2 of REACH Annex IX Nr 9.2.1.2, the study does not need to be conducted as the substance is regarded as readily biodegradable and to be highly insoluble in water (see Sect. 4.8).

 

Biodegradation in soil

In accordance with column 2 of REACH Annex IX Nr 9.2.1.2, the study does not need to be conducted as the substance is regarded as readily biodegradable. Furthermore in the performed exposure assessment the resulting RCRs are well below 0.1 (see CSR). Therefore further testing is

not required.

 

Mode of degradation in actual use

Data for mode of degradation in actual use are not required under REACH.
