Carcinogenicity
Administrative data
Description of key information
The test substance was tested for carcinogenicity by oral administration in two experiments in mice and in one experiment in rats [1]. In one experiment in mice, it induced histiocytic sarcomas and lymphomas in both males and females and benign ovarian tumours in females. In an experiment in mice lacking one allele of the p53 tumour suppressor gene, it increased the incidence of lymphomas. This result was confirmed in a separate study reported as an abstract. It induced benign renal tumours in male rats and benign phaeochromocytomas in males and females [2, 3].
