Carcinogenesis Studies of Eugenol (CAS No. 97-53-0) in F344/N Rats and B6C3F1 Mice (Feed Studies)

摘要

Carcinogenesis studies of eugenol, a widely used flavor additive and chemical intermediate, were conducted by feeding diets containing 6,000 or 12,500 ppm of eugenol to groups of 50 female F344/N rats and by feeding diets containing 3,000 or 6,000 ppm to groups of 50 male F344/N rats and B6C3F1 mice of each sex for 103 weeks. Groups of 40 rats and 50 mice of each sex served as controls. Dose levels selected for the two year studies were based on thirteen-week (91-day) studies in which dietary concentrations for the six groups ranged from 0 to 12,500 ppm. Other than a -10% difference from controls in body weights in the 12,500 ppm male rats, no chemically related gross or histopathologic effects were observed.
