Description of key information

Fish (no species identified): 30 day Chv = 369mg/l (QSAR model)

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater fish:
369 mg/L

Additional information

According to the conditions for adaptation listed in column 2 in Annex IX under section 9.1 of the regulation, long term aquatic toxicity testing shall be proposed if the chemical safety assessment indicates the need to investigate further the effects on aquatic organisms. In this case, the assessment does not indicate such a need therefore testing for this end point is not required.

QSAR predictions show that 2 -(2 -butoxethoxyethanol) is of low toxicity to fish at chronic levels of exposure with a predicted Chv (equivalent to a NOEC) value of 369mg/l.
