EC number: 265-149-8 | CAS number: 64742-47-8 A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 150°C to 290°C (302°F to 554°F).

Additional information
In a static 48 -hour acute daphnid (Daphnia magna) test (OECD 202; KS = 1), 20 animals/dose were exposed to kerosine petroleum, hydrodesulfurised at nominal concentrations of 0, 0.1, 0.3, 1.4, 6.8, and 34 mg/L. The EL50 was 1.4 mg/L with a 95% confidence interval of 1.0 to 2.0 mg/L. The No Observed Effect Loading (NOEL) rate was 0.3 mg/L determined by immobilisation (Exxon, 1995d).
The toxicity for four kerosine products was tested using WAF methodology. In these reliable supporting studies the 48 -hour EL50 (loading rate resulting in 50% immobilization of Daphnia) varied between 1.9 and 89 mg/L. The NOELs for these tests varied between 0.3 and 40 mg/L (Shell 1995, Shell 1994, Exxon 1995e, Exxon 1995f).
