Additional information

Conclusion on classification

Acute toxicity results were as follows:

Daphnia: 24h, 48h, EC50 value: > 100 mg/L (based on test item nominal loading rate)

Algal growth test: 72h EbC50, ErC50, EyC50 value: > 100 mg/L (based on test item nominal loading rate)

Fish: 24h, 48h, 72h and 96h EC50 value: > 100 mg/L (based on test item nominal loading rate)

Microorganisms: The 3-hour EC50: > 1000 mg/L

No chronic toxicity studies are available.

Based on the information above and in addition to the substance being not readily biodegradable and not bioaccumulative the substance is therefore not classified for short-term or long-term hazards to the aquatic environment according to section 4.1.2.6 of Regulation (EC) 1272/2008.
