Other physicochemical hazards

There are no significant hazards expected with intended use. Specific Hazards Dust explosion (like most finely grained organic powders) －1－ Main Symptoms Acute Inhalation Toxicity Exposure to excessive amount of dust may cause physical irritation to respiratory tract. Acute Oral Toxicity Low acute toxicity in animal experiment. Acute Eye Irritation May cause slight transient irritation. Acute Skin Irritation May be non-irritant. Sensitization From test no apparent significant hazards are expected . (Only few cases reported on incidental allergy-related conjunctivitis or dermatitis.)

Potential chronic health

Slight pulmonary fibrosis has been reported in rats upon chronic inhalation exposure to a toner at 4mg/m3 every day for 2 years. No pulmonary change was found at 1mg/m3. These findings show that exposure to excessive amounts of powder may cause damage to lungs. However, normal use and handling of this product as intended, does not result in inhalation of excessive amounts of powder. Carcinogenicity In 1996, the IARC re-evaluated carbon black as a Group 2B carcinogen for which there is inadequate human evidence, but sufficient animal evidence. However, there is a two-year inhalation study for a toner containing carbon black, which demonstrated no association between toner exposure and tumour development in rats even if the amount of carbon black powder is changed. The Classification of The Chemical Product This preparation is not classified as dangerous according to Regulation (EC) No 1272/2008.
