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: not available

- 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 Daphnia magna is < 1 mg/L. Therefore, propylparaben has to be classified as H412: Harmfull to aquatic life with long lasting effects (Category 3)
