Additional information

Conclusion on classification

Key information for classification:

- Biodegradation in water: Readily biodegradable (OECD 301D)

- Bioaccumulation: BCF <0.5 - 15 L/kg (no significant bioaccumulation potential)

- Aquatic acute toxicity:

Fish: LC50 (96 h) = 15.6 mg/L

Aquatic invertebrates: EC50 (48 h) = 26.6 mg/L

Algae: ECr50 (72 h) = 16.2 mg/L

- Aquatic chronic toxicity:

Fish: No data available

Aquatic invertebrates: No data available

Algae: NOEC (72 h) = 4.6 mg/L (based on the growth rate)

Classification justification according to CLP

Based on the data above, the substance is considered to have low potential for bioaccumulation and is rapidly biodegradable. The acute aquatic toxicity L(E)C50 is > 10 mg/L. Valid chronic toxicity data are only available for algae (NOEC (72 h) > 1 mg/L). Therefore, it can be concluded that the substance does not need to be classified and labelled as environmental hazardous according to the Regulation (EC) No 1272/2008 (CLP) and the Regulation (EU) No 2015/1221 (7th ATP).
