Additional information

Conclusion on classification

Degradation

Biodegradation: readily biodegradable: 60% (O2 consumption) after 28 days (OECD 301C)

Bioaccumulation

Log Kow: 0.03 (OECD 117)

Aquatic toxicity

96 h, LC50 (Pimephales promelas): 185 mg/L (nominal)

48 h, EC50 (Daphnia magna): > 100 mg/L (nominal)

72 h, ErC50 (Pseudokirchnerialla subcapitata): > 100 mg/L (nominal); > 28 mg/L (geometric mean)

72 h, NOEC (Pseudokirchnerialla subcapitata): ≥ 100 mg/L (nominal); ≥ 28 mg/L (geometric mean)

Non-classification according to CLP

Chronic data are not available for 2,2'-[ethane-1,2-diylbis(oxy)]bisethyl diacetate. However, based on the data above,2,2'-[ethane-1,2-diylbis(oxy)]bisethyl diacetate is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute toxicity L(E)C50 values are all > 1 mg/L for fish, aquatic invertebrates and algae. Thus, 2,2'-[ethane-1,2-diylbis(oxy)]bisethyl diacetate does not need to be classified and labeled as environmental hazard according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP).

Non-classification according to DSD/DPD

Based on the data above, 2,2'-[ethane-1,2-diylbis(oxy)]bisethyl diacetate is considered to be rapidly degradable and has low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are all > 1 mg/L for fish, aquatic invertebrates and algae. Thus, 2,2'-[ethane-1,2-diylbis(oxy)]bisethyl diacetate does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
