Description of key information
In accordance with column 2 of REACH Annex IX, the soil simulation test does not need to be conducted as the substance is readily biodegradable.
Key value for chemical safety assessment
Additional information
The biodegradation of LAS-TEA may be further described by the biodegradation of LAS-Na and TEA according to the read-across statement in which full dissociation of the LAS-TEA in water is supported. For the soil compartment this is relevant for indirect applications via sludge application.
TEA is shown to biodegrade rapidly in soil, with max. half-life times of 1.8 days.
Further maximum mineralisation half-life was determined in soil of 5.4 days.
Half-life in sludge-amended soil after application of sludge of LAS-Na was >7 -<22 days based on recovered LAS-Na.
