1 l.TOXICOLOGICAL INFORMATION Skin Corrosive : Not a corrosiveSkin irritant (rabbit) : Not an irritant*lEye Irritant (rabbit) : Not an irritant*1 (based on toxicity data of the ingredients of print)Skin Sensitization (guinea-pig) : Not a sensitizer*lAcute Toxicity Swallowedlt LD50 (rat) : > 2000 mg/kg (practically non-toxic) *ISkinLl LDSO (rabbit) : Not availableInhalcdtt LCSO (rat) : Not availableChronic Toxicity : The results obtained from a Xerox sponsored. Chronic Toner Inhalation Study, demonstrated no lungchange in rats for the lowest (ling/m3) exposure level (Le. the level most relevant to potential human exposure). A very slightdegree of‘fibrosis was noted in 25% of the animals at the middle (4mg/m3) exposure level. while a slight degree of fibrosis wasnoted in all the animals at the highest (16 mgi’m3) exposure level. These findings are attributed to "lung overloading". a genericresponse to excessive amounts of any dust retained in the lungs for a prolonged period. This study was conducted using aspecial test toner to comply with EPA testing protocol. The test toner was ten times Inore rcspirable than commerciallyavailable Xerox toner, and would not be functionally suitable for Xerox equipment.“ ICarcinogenicity : Carbon Black is classified as “Group 23(possib1y carcinogenic to humans) " by IARC. But weobtained the results from a Chronic Toner Inhalation Study, that commercially available Xerox toner has no evidence ofhuman carcinogens. Any other ingredient is not classified as “Carcinogens ”1"“Mutagenicity: Ames Assay : NegativeReproduction and Development : Not classified as “ Reproductive and Development chemicals*1 This information is based on toxicity data for similar materials and ingredients.
