Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The chronic toxicity to aquatic invertebrates was tested in a reproduction test according to OECD 211 using the supporting substance isobutyl acetate (CAS 110 -19 -0). The 21 -d NOEC was determined to be 23 mg/L, the EC50 34 mg/L (CERI, 2000). These values are confirmed by ECOSAR v1.00 (ECT, 2009). The chronic value for n-butyl acetate was estimated to be 26 mg/L.

Chronic toxicity is therefore not expected.

For the justification for read-across from iso-butyl acetate to n-butyl acetate see the documentation in section 13.
