Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
In accordance with column 2 of REACH Annex IX, simulation testing is not required since the substance is readily biodegradable.
Data for the mono ester of di-isodecyl phthalate (mono isodecyl phthalate) exhibited a relatively rapid rate of biodegradation in a natural aerobic marine sediment, with a measured half-life of 25 ± 6 hours, based on the results of two replicates.
Key value for chemical safety assessment
Additional information
The mono ester of di-isodecyl phthalate (mono isodecyl phthalate) was found to biodegrade at a relatively rapid rate in a natural aerobic marine sediment, with a measured half-life of 25 ± 6 hours, based on the results of two replicates. The investigators also evaluated the biodegradability of other mono phthalate esters (MPEs) in marine sediment and some MPEs in freshwater sediments and found that, in general, all the MPEs exhibited relatively similar half-lives in marine and freshwater sediment, ranging from 16 to 39 hours. Although the biodegradability of mono isodecyl phthalate was not evaluated in freshwater sediment, based on biodegradation data for other MPEs in both sediments, mono isodecyl phthalate would also be expected to exhibit a half-life in freshwater sediment equivalent to its half-life in marine sediment. Based on these data, the diester (DIDP) is expected to exhibit a half-life in sediment under aerobic conditions similar to the measured half-life of the mono ester.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
