Description of key information

EC50 (3h) = 140 mg/L for activated sludge 
EC50 (16.9h) > 10 g for Pseudomonas putida

Key value for chemical safety assessment

Additional information

Since no data for 2 -hexyldecan-1-ol ethoxylated (< 2.5 EO) are available, toxicity to microorganisms is assessed on the basis of data from two studies with similar alcohol ethoxylates (C12, 4 EO, CAS 9002-92-0 and C12-14, 6 EO, CAS 68439-50-9).

In a respiration test with domestic activated sludge according to EG-guideline 88/302/EG and GLP (Sasol, 1997), an EC50 (3h) of 140 mg/L was determined. This finding is supported by the result of a test with Pseudomonas putida according to DIN 38412, part 8 and GLP (Sasol, 1996) that revealed an EC50 (16.9 hours) > 10 g/L.
