Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 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, the water and sediment simulation test does not need to be conducted as the substance is readily biodegradable.
Key value for chemical safety assessment
Additional information
Because of ready biodegradability of LAS-MIPA in water, no study into biodegradation of LAS-MIPA in a water and sediment simulation test is required.
The biodegradation of LAS-MIPA may be further described by the biodegradation of LAS-Na and MIPA according to the read-across statement in which full dissociation of the LAS-MIPA in water is supported.
No water and sediment simulation study is available for MIPA .
Biodegradation of LAS-Na in sediment is rapid.Mineralization (14CO2 production) was best described by a First Order Model (r2 > 0.99), indicating that parent and metabolites were equally bioavailable to undergo mineralization. The rate constant for mineralization was 0.06 day-1.
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.
