The oral toxicity of
1,1'-(1,1,2,2-tetramethylethylene)dibenzene was assessed according to
OECD guideline 401 and EU method B.1. The test item was administered to
one group of 3 male and 3 female Wistar rats by oral gavage, at a single
dose of 2000 mg/kg bw. No mortality occurred, no clinical signs were
observed and no macroscopic abnormalities were seen at necropsy. Based
on these observations, the estimated acute oral toxicity LD50 of
1,1'-(1,1,2,2-tetramethylethylene)dibenzene in rats of both sexes
observed for a period of 15 days is greater than 2000 mg/kg bw.
