The Canadian government has confirmed its conclusion that four thiols
, three of which are used as food flavouring agents, are not harmful.
The conclusion of the final screening assessment, dated 20 October, makes further regulatory action against the substances under the country's Chemicals Management Plan (CMP) extremely unlikely.
The four substances are:
- dimethyl sulfide;
- benzyl disulfide;
- tert-dodecyl mercaptan; and
- grapefruit mercaptan.
