Additional information

Due to the rapid hydrolysis of the parent compound, the PNEC derivation is based on the results for the hydrolysis product 2 -ethylhexanoic acid (CAS 149 -57 -5).

Conclusion on classification

Following DSD/DPD, the substance is not to be classified as dangerous for the environment since the substance is readily biodegradable and the log Pow is < 3 (no experimentally determined BCF).

Following GHS, the substance is not to be classified as hazardous to the aquatic environment since the substance is readily biodegradable and the log Pow is < 4 (no experimentally determined BCF).

Data from HCl have not been taken into consideration as observed effects are caused by a pH-shift in the test medium.
