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

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 (1 mg/m3) 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 animals at the middle (4 mg/m3) exposure level, while a slight degree of fibrosis was noted in all the animals at the highest (16 mg/m3) exposure level. The findings are attributed to lung overloading, a generic response to excessive
