Conclusion on classification

Classification related key information

Biodegradation in water: Readily biodegradable: 88.4% (ThOD) in 28 days (OECD 301 F)

Log Kow: -0.14


Acute toxicity:

- to fish: LC50 (96h) = 15 mg/L for Danio rerio (OECD 203)

- to aquatic invertebrates: EC50 (48h) > 10 mg/L for Daphnia magna (ISO 634115)

- to algae: ECr50 (72h) = 37 mg/L, for Pseudokirchneriella subcapitata (OECD 201)


Chronic toxicity:

- to fish: not available

- to aquatic invertebrates: not available

- to algae: NOEC (72h) = 20 mg/L for Pseudokirchneriella subcapitata (OECD 201)


Classification justification according to CLP

Based on the data above, sodium ethylparaben is considered rapidly biodegradable. The acute aquatic toxicity LC50 is > 1 mg/L for all trophic levels. No chronic data are available for fish and invertebrates. The NOEC for P. subcapitata is > 1 mg/L. Therefore, sodium ethylparaben does not need to be classified and labelled as environmental hazard according to the Regulation (EC) No. 1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2ndATP).
