Description of key information

LC50 (14d) > 1000 mg/kg soil dw. for Eisenia fetida 

Key value for chemical safety assessment

Additional information

As no study on toxicity to soil organisms is available for alcohol ethoxylate ((Z)-9-Octadecen-1-ol ethoxylated, < 2.5 EO, CAS 9004-98-2), a category read-across is prepared to an analog alcohol ethoxylate (C16-18, 10 EO, CAS 61791-28-4). The study was conducted according to OECD guideline 207 under GLP conditions, with the earthworm Eisenia fetida as test organism (BASF, 1990). Up to the highest test concentration of 1000 mg/kg dw. no mortality was observed.
