Two-year dermal carcinogenicity bioassay of triclosan in B6C3F1 mice.

ABSTRACT: Triclosan is a widely used antimicrobial agent in personal care products, household items, medical devices, and clinical settings. Due to its extensive use, there is potential for humans in all age groups to receive lifetime exposures to triclosan, yet data on the chronic dermal toxicity/carcinogenicity of triclosan are still lacking. We evaluated the toxicity/carcinogenicity of triclosan administered dermally to B6C3F1 mice for 104 weeks. Groups of 48 male and 48 female B6C3F1 mice received dermal applications of 0, 1.25, 2.7, 5.8, or 12.5 mg triclosan/kg body weight (bw)/day in 95% ethanol, 7 days/week for 104 weeks. Vehicle control animals received 95% ethanol only; untreated, naïve control mice did not receive any treatment. There were no significant differences in survival among the g
