Conclusion on classification

Aquatic environment classification:

Diethyl carbonate proved to be readily biodegradable (>81% biodegradation after 28 d).

The lowest acute EC/LC50 value in aquatic tests is the L(E)C50>45 mg/L for fish (calculated).

Due to the fact that diethyl carbonate is proven to be readily biodegradable and because of its low log Kow (1.21-1.33) the substance is not classified as dangerous/hazardous for the environment according to Directive 67/548/EEC and according to the Regulation (EC) 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation):

Lowest reliable L(E)C50 value:                 >45 mg/L fish (calculated)

Ready biodegradable                                yes

log Pow                                                    < 3

Special concern:                                        no


According to 67/548/EEC Annex 1:      not classified


According to GHS:

Physico-chemical hazard:             Flammable liquid 3 (H226)

Hazardous to the environment      not classified, no hazard statement

                                                   Reason for classification:    L(E)C50: > 45 mg/L; readily biodegradable, log Pow<4

Hazardous to the atmospheric environment:

(Hazardous to the ozone layer: This includes substances which are listed in Annex I to Regulation (EC) No 2037/2000 of the European Parliament and of the Council of substances that deplete the ozone layer (1) and its subsequent amendments):

Diethyl carbonate is not listed in Annex I of (EC) No 2037/2000.
