EC number: 295-422-7
CAS number: 92045-41-5
A complex combination of hydrocarbons obtained by the vacuum distillation of used lubricating oil and boiling in the range of approximately 200°C to 360°C (392°F to 680°F).
For one of the substances of the category (CAS 70514-12-4), the short term toxicity to aquatic invertebrates was assessed performing two appropriate tests on Daphnia magna and Artemia floridae. Data support the lack of acute aquatic toxicity. The values found are the following:- Daphnia magna: EL50: 4980-6225 mg/l- Daphnia magna: EC50: 4,65 mg/l- Artemia salina: EL50: > 20000 - 25000 mg/l - Artemia salina: EC50: > 12,8 mg/lFor the other substance of the category (CAS 64742-58-1), the short term toxicity to aquatic invertebrates was assessed to be > 10000 mg/l WAF. The other studies performed according to different methods (and using methylene chloride as solvent) were considered less appropriate for investigating the toxicity to aquatic invertebrates of substance; however, the results of these studies support the lack of acute toxicity to aquatic invertebrates observed in the study selected as key study.Overall, using the read across approach, the substance of interest has not acute aquatic toxicity; however, remarkable differences observed between the nominal and measured effect concentration in Daphnia magna study do not allow a reliable classification of the substance for aquatic chronic toxicity.In light of the uncertainties above discussed a short-term toxicity test on Daphnia magna was performed using the substance of interest (CAS 92045-41-5) at nominal concentration of 100 mg/l WAF. No effect was observed after 48 hours, so the substance has not to be considered as toxic to aquatic invertebrates.
