Comments
"TSCA Definition 2008: A complex combination of hydrocarbons from distillation of the products from a thermal cracking process. It consists predominantly of unsaturated hydrocarbons having carbon numbers predominantly in the range of C6 through C12 and boiling in the range of approximately 65.degree.C to 220.degree.C (148.degree.F to 428.degree.F)." [ChemIDplus] Not a skin sensitizer in Buehler test of guinea pigs; No systemic effects observed in females (hydrocarbon nephropathy in males) in 21-day inhalation study of rats at concentrations up to 9,880 mg/m3 for 6hrs/day; Severe skin irritation but no systemic effects observed in 28-day dermal study of rabbits at doses up to 2,000 mg/kg; [IUCLID] An eye and mucous membrane irritant; Inhalation may cause anesthetic and other CNS effects; An aspiration hazard by ingestion (may cause lung injury); Chronic exposure may cause injury to liver, kidney, blood, nervous system, and skin; [Hess MSDS]
