- Based on inadequate human data and sufficient evidence of carcinogenicity in animals; namely, significantly increased incidences of benign and malignant tumors at multiple sites in one strain of female mice treated orally, dermally, and by inhalation. There is also evidence of mutagenicity in a variety of test systems.
- This may be a synopsis of the full weight-of-evidence narrative.
