Q11: Carbon Black and Titanium Dioxide (TiO2) show up as carcinogenic hazards on some of our SDSs, and not on others. In other cases, PolyOne has been advised by the suppliers of certain raw materials (carbon black and titanium dioxide are two prime examples) that the classification of their materials as IARC category 2B carcinogens are based on certain studies involving rats, and due to a toxicological phenomenon known as “rat lung overload,” carcinogenicity seen in such rats is not believed to be extended to humans.
