Carcinogenicity:
Ingredient CAS No. Class Description Regulation
Carbon Black 1333-86-4 Grp. 2B: Possible human carc. International Agency for Research on Cancer
Titanium Dioxide 13463-67-7 Grp. 2B: Possible human carc. International Agency for Research on Cancer
Additional Information:
This document covers only the 3M product. For complete assessment, when determining the degree of hazard, the material
being abraded must also be considered.
This product contains titanium dioxide. Cancer of the lungs has been observed in rats that inhaled high levels of titanium
dioxide. No exposure to inhaled titanium dioxide is expected during the normal handling and use of this product. Titanium
dioxide was not detected when air sampling was conducted during simulated use of similar products containing titanium
dioxide. Therefore, the health effects associated with titanium dioxide are not expected during the normal use of this product.
Toxicological Data
If a component is disclosed in section 3 but does not appear in a table below, either no data are available for that endpoint or
the data are not sufficient for classification.
