title: [Carcinogenic activity of ethylene oxide and its reaction products 2-chlorethanol, 2-bromoethanol, ethylene glycol and diethylene glycol. II. Testing of 2-chlorethanol and 2-bromoethanol for carcinogenic activity].
abstract: The compounds 2-chloroethanol and 2-bromoethanol were administered once weekly subcutaneously to groups of 100 female NMRI mice, in the case of 2-chloroethanol in 3 dosages (3.0, 1.0 and 0.3 mg, single dosage per mouse) and 2-bromoethanol in 2 dosages (1.0 and 0.3 mg, single dosage per mouse). Tricaprylin was used as solvent. The mean total dosage per mouse was 175.9,76.3 and 23.0 for 2-chloroethanol and 72.7 and 21.0 mg for 2-bromoethanol. In addition, by intragastric treatment of rats with two dosages (single dosage 10.0 and 2.5 mg/kg body weight), 2-chloroethanol was examined for carcinogenicity. The solvent used here was salad-oil. The mean total dosage per rat amounted to 1706 or, respectively, to 434 mg/kg of body weight. No carcinogenic effect could be determined in the case of either of the test substances, 2-chloroethanol and 2-bromoethanol.
