[Comment] The results of subcutaneous and intramuscular induced carcinogenesis in experimental animals and the results of in vitro and in vivo genotoxicity studies are not relevant to human health and are inappropriate to form the basis of carcinogen classification of the two pigments. [Response] 
The results from animal studies via parenteral administration and in vitro testing, although not exposure routes directly relevant to human exposure, provides insight into the carcinogenic and genotoxic potential of the pigments.
