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.
