Conclusion on classification

The lowest aquatic toxicity result for Oxooil LS9 is the EC50 of 12 mg/l for Daphnia magna. Since the substance is not readily biodegradable (6% in 28 days), Oxooil LS9 is classified as harmful to aquatic organisms (R52) and may cause long-term adverse effects in the aquatic environment (R53), according to the general classification and labelling requirements for dangerous substances and preparations (Directive 67-548-EEC).

According to the criteria of the EU-GHS classification, labelling and packaging (CLP) regulation (EC) No 1272/2008, Oxooil LS9 is classified for chronic aquatic toxicity, Category 3.
