SECTION 11 - TOXICOLOGICAL INFORMATION
This material has been evaluated by Xerox Corporation. The toxicity data
noted below is based on test results of similar toners.
Oral LD50: > 5 g/kg (rats), practically non-toxic
Dermal LD50: > 5 g/kg (rabbits), practically non-toxic
Inhalation LC50: > 5 mg/l (rats; 4 hour exposure), practically non-toxic
Inhalation LD50: > 20 mg/l (rats; calculated for 1 hour exposure), non-toxic per
DOT
Eye Irritation: Non-irritating (rabbits)
Skin sensitization: Non-irritating (rabbits; human patch)
Human Patch: Non-irritating, non-sensitizing
Mutagenicity: No mutagenicity detected in Ames assay
Carcinogens: None present
Additional Information: The results obtained from a Xerox-sponsored Chronic
Toner Inhalation Study demonstrated no lung changes in rats for the lowest
3
(1 mg/m
) exposure level (i.e., the level most relevant to potential human
exposure). A very slight degree of fibrosis was noted in 25 percent of the
3
animals at the middle (4 mg/m
) exposure level, while a slight degree of
3
fibrosis was noted in all the animals at the highest (16 mg/m
) exposure level.
The findings are attributed to lung overloading, a generic response to excessive
