Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: Readily biodegradable: 91.5% (ThOD) in 28 days (OECD 301 F)
Log Kow: 2.8 (average value from seven sources)
Acute toxicity:
- to fish: LC50 (96h) = 6.4 mg/L for Danio rerio (OECD 203)
- to aquatic invertebrates: EC50 (48h) = 15.4 mg/L for Daphnia magna (ISO 634115)
- to algae: ECr50 (72h) = 16 mg/L, for Pseudokirchneriella subcapitata (OECD 201)
Chronic toxicity:
- to fish: NOEC 0.165 mg/L for Danio rerio (OECD 234)
- to aquatic invertebrates: NOEC 0.25 mg/L for Daphnia magna (OECD 211)
- to algae: NOEC (72h) = 2.1 mg/L for Pseudokirchneriella subcapitata (OECD 201)
Classification justification
Based on the data above the substance is considered rapidly biodegradable. The acute aquatic toxicity LC50 is > 1 mg/L for all trophic levels. Chronic data are available for algae and invertebrates. The NOEC for Danio rerio is < 1 mg/L. Therefore, propylparaben has to be classified as H412: Harmfull to aquatic life with long lasting effects (Category 3)
