Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The 3 hour EC10 of 3-methoxybutan-1-ol is 155.0 mg/l and the EC20 is 399.3 mg/l. The 3 hour EC50 of 3-methoxybutan-1-ol could not be determined as at the highest nominal concentration of 1000 mg/l less than 50% inhibition was noted after 3 hours incubation. The 3 hour EC50 is therefore higher than 1000 mg/l under the present test conditions.

Key value for chemical safety assessment

Additional information

The study by IBACON (2009) is a 3 hour static ecotoxicity test with activated sludge, following guidelines OECD 209 and EU Method C11. 5 concentrations were tested. It is GLP compliant and is considered reliable and fully adequate for assessment.
