Additional information

Conclusion on classification

The substance has a log Kow of 1.34, is highly water soluble with 0.772 g/L and is not readily biodegradable. Acute toxicity studies showed most critical effects for acute toxicity to algae with an EC50 = 0.17 mg/L.

In accordance with the criteria set in CLP Regulation, EC No 1272/2008, the substance is classified as:

- Category Acute 1

- Category Chronic 1
