Conclusion on classification
According to Directive 67/548 EC and the results mentioned hereafter, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues is classified R52/53.
* Short term Toxicity to Fish: LC50-96h > 100 mg/L
Based on the results of this study, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues would not be classified as toxic to fish in accordance with the Directive 67/548/EC.
* Short term toxicity to aquatic invertebrates: EC50-48h = 33.67 mg/L
Based on the results of this study, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues is classified as harmful for aquatic invertebrates in accordance with the Directive 67/548/EC.
* Toxicity to aquatic algae: EC50-72h > 100 mg/L
Based on the results of this study, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues would not be classified as toxic to algae in accordance with the Directive 67/548/EC.
* Toxicity to aquatic micro-organisms: EC50-3h > 100 mg/L
Based on the results of this study, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues shows low toxicity to activated sludge.
* Dodecane-12-lactam, manufacturing of, by-products from, distillation residues is not readily biodegradable
According to GHS regulation, these results are conclusive and so show that Dodecane-12-lactam, manufacturing of, by-products from, distillation residuesis classified in the acute category III (Harmful to aquatic life) and chronic category III (Harmful to aquatic life with long lasting effects).
According to CLP, Dodecane-12-lactam, manufacturing of, by-products from, distillation residues is classified in the chronic category III (Harmful to aquatic life with long lasting effects).
