Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
LAS-MIPA is readily biodegradable. No studies on degradation of LAS-MIPA in water-sediment or in soil are available. In accordance with column 2 of REACH Annex IX, the water and sediment simulation test and biodegradation test in soil do not need to be conducted.
LAS-Na and MIPA are also readily biodegradable.
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. For the soil compartment this is relevant for indirect applications via sludge application.
MIPA
For MIPA no studies on degradation in water-sediment or in soil are available.
LAS-Na
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.
Half-life in sludge-amended soil after application of sludge of LAS-Na was >7 -<22 days based on recovered LAS-Na.
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.
