EC number: 308-714-7 | CAS number: 98219-47-7 A complex combination of hydrocarbons obtained by the treatment and distillation of light steam-cracked petroleum naphtha. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C5 through C6 and boiling in the range of approximately 35°C to 80°C (95°F to 176°F).

Description of key information
Toxicity to algae data are available for 2 streams within this Category. The ErL50 growth rate range was 2.3 mg/L at 72 hours and 2.1 – 2.2 mg/L at 96 hours. A 72 and 96 hour NOELR of 0.18 mg/L was cited.
Key value for chemical safety assessment
Additional information
CAS No 68513-69-9: This study is GLP compliant and follows a standard guideline. It is considered reliable and acceptable for use as a key study. Based on measured concentrations, the EC50 was 2 mg/L at 72 hours and 1.8 mg/L at 96 hours for growth rate, and 1.3 mg/L at 72 and 96 hours for biomass. Based on actual loading rates, the EL50 was 2.3 mg/L at 72 hours and 2.1 mg/L at 96 hours for growth rate, and 1.5 mg/L at 72 hours and 1.4 mg/L at 96 hours for biomass.
CAS No 68513-69-9 and 68921-67-5: This is a GLP compliant, guideline study considered adequate for assessment. After 72 and 96 hours of exposure to Pyrolysis C10+ Fuel Oil (from Pyrolysis Gasoline Distillation) the following conclusions were made. Based on actual loading rates, effects on growth rate (r) gave an EL50 of 2.3 mg/L at 72 hours and 2.2 mg/L at 96 hours and effects on biomass (b) gave an EbL50 of 1.3 mg/L at 72 hours and 1.2 mg/L at 96 hours. Based on measured concentrations, effects on growth rate (r) gave an ErC50 of 1.7 mg/L at 72 hours and an ErC50 of 1.6 mg/L at 96 hours and effects on biomass (b) gave an EbC50 of 0.95 mg/L at 72 hours and an EbC50 of 0.91 mg/L at 96 hours. Effects based on average specific growth rate and area under the growth curves gave a 72 and 96 hour NOELR of 0.18 mg/L and a NOEC 0.12 mg/L.
Although measured concentrations were reported as the test substance is a hydrocarbon stream with various components reporting a measured concentration does not relate to a concentration of the raw stream. The results reported as WAF which better represent the potential toxicity of the test substance have been used instead.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
