EC number: 273-110-1 | CAS number: 68938-03-4 The complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isononanal. It consists predominantly of C6 olefins and paraffins and C9 alcohols and aldehydes and boiling in the range of approximately 110°C to 202°C (230°F to 396°F).

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.
