The toxicity data noted below is based on the test result of similar
reprographic materials.
Acute toxicity
Chronic toxicity
Other Toxic Effects
Other information
The IARC (International Agency for Research on Cancer) has listed
carbon black as "possibly carcinogenic to humans".
The classification is based on studies evaluating pure, "free" carbon
black. In contrast, toner is a formulation composed of specially
prepared polymer and a small amount of carbon black (or other
pigment).
In the process of making toner, the small amount of carbon black
becomes encapsulated within a matrix. Regarding extensive testing of
toner, including a chronic bioassay (test for potential carcinogenicity),
exposure to toner did not produce evidence of cancer in exposed
animals. The results were submitted to regulatory agencies and
published extensively.

Ecotoxicity
The environmental impact of this product has not been fully
investigated. However, this preparation is not expected to present
significant adverse environmental effects.
Explosive properties
Fine dust dispersed in air, in
sufficient concentrations, and in
the presence of an ignition source
is a potential dust explosion
hazard.

Incompatible products
None.
Conditions to Avoid
Prevent dust cloud. Fine dust
dispersed in air, in sufficient
concentrations, an ignition
source is and in the presence of a
potential dust explosion hazard.

irritation.
LD50 Oral:
> 5g/kg (rat)
LD50 Dermal:
> 5g/kg (rabbit)

No known effect
Product Information
Chronic Effects
No known effects under normal
use conditions. Repeated or
prolonged inhalation may cause
irritation of the respiratory tract
as can occur with the inhalation
of any non- toxic dust. Minimum
respiratory or eye irritation may
occur as with exposure to large
amounts of any non-toxic dust.
Main symptoms
Overexposure may cause: mild
respiratory irritation similar to
nuisance dust.
Aggravated Medical
Condition
None under normal use
conditions.
