[Comment] The lack of regulations could lead to unregulated use in foods. [Response] 
The safety of all materials used for packaging foods is controlled under the Food and Drug Regulations, which essentially prohibit the sale of a food in a package that may impart a harmful substance to its contents. For most flavours, including isophorone, there are no provisions in the Food and Drug Regulations that control their addition to foods, although such use must not result in a violation of the Food and Drugs Act. In the case of isophorone, the screening assessment did not identify any health risks for which risk management measures would be required.
