Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Long-term toxicity to fish
Administrative data
Link to relevant study record(s)
Description of key information
Fish (no species identified): 30 day Chv = 369mg/l (QSAR model)
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 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.
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.
