A complex combination of hydrocarbons produced by the distillation of products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly in the range of C11 through C30 and boiling in the range of approximately 205°C to 450°C (401°F to 842°F). It contains a relatively large proportion of tricyclic aromatic hydrocarbons.
an acute dermal toxicity study, groups of young adult, New Zealand White
rabbits (4/sex) were dermally exposed to light catalytically cracked
distillate for 24 hours at a dose of 2000 mg/kg bw that covered 10% of
the body surface area. Animals
were then observed for 14 days.
mortality or systemic toxicity was observed. Dermal irritation
ranged from slight to moderate erythema, desquamation, and
coriaceousness. Moderate to severe oedema was observed, and slight to
marked atonia and fissuring were observed. At
necropsy, no significant gross pathological observations were noted. The
dermal LD50 was determined to be greater than 2000 mg/kg in males and
females which is not classified according to EU criteria.
study received a Klimisch score of 2 and is classified as reliable with
restrictions because it is an acceptable and well documented study
