Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
