Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Toxicity to soil macroorganisms except arthropods
Administrative data
Link to relevant study record(s)
Description of key information
In accordance with column 2 of REACH Annex IX and X, the toxicity testing on invertebrates study does not need to be conducted as direct and indirect exposure of the soil compartment is unlikely. The reaction product and its constituent substances show a low bioaccumulative (low log Kow ) potential. Hence, a relevant distribution into soil and a considerable exposure of soil macroorganisms is not expected. There are however 4 studies with the major constituent (LAS) of the substance being registered (Marlon ARL).
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 6.2 mg/kg soil dw
Additional information
The 14-day acute toxicity of LAS to earthworms is reported as LC50>1000 and EC10 = 277 mg/kg soil dry weight.
The 21-day chronic toxicity of LAS to annelids is reported as EC10 = 6.2 mg/kg soil dry weight.
The 28-day chronic toxicity of LAS to oligochaetes is reported as EC10 = 46 mg/kg soil dry weight.
The reported EC10 for eleven species of soil dwelling organisms exposed to LAS ranges from 6.2 - 383 mg/kg soil dry weight.
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.
