Description of key information

No data are available for the carcinogenicity of CTO. However, further testing is not considered necessary because:
• The substance is not classified for mutagenicity; and
• There is no evidence from the repeated dose studies that constituents of CTO are able to induce hyperplasia or pre-neoplastic lesions.
