Description of key information

No carcinogenicity study results are available. Nevertheless from the data available on the reaction mass of cerium dioxide and lanthanum oxide and lanthanum fluoride, as well as on the related mono-constituents cerium dioxide or lanthanum oxide, testing for carcinogenicity is not required as all these subtsances are not mutagenic and as no evidence of pre-neoplastic lesions was observed in the repeated dose toxicity study using cerium dioxide.
