Acute oral toxicity—LD50 of this toner is over 2,000mg/kg.
Mutagenicity—The result of Ames test is negative.
In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen
(possible human carcinogen). This classification is given to chemicals
for which there is inadequate human evidence, but sufficient animal
evidence on which to base an opinion of carcinogenicity. The
classification is based upon the development of lung tumors in rats
receiving chronic inhalation exposures to free carbon black at levels
that induce particle overload of the lung. Studies performed in animal
models other than rats did not show any association between carbon
black and lung tumors. Moreover, a two-year cancer bioassay using
a typical toner preparation containing carbon black demonstrated
no association between toner exposure and tumor development in
rats.
In a study in rats of chronic inhalation exposure to a typical toner,
a mild to moderate degree of lung fibrosis was observed in 92% of
the rats in the high concentration (16mg/m
a minimal to mild degree of fibrosis was noted in 22% of the animals
in the middle (4mg/m
was reported in the lowest (1mg/m
relevant level to potential human exposures.
