Synthetic flavoring substances and adjuvants

This is the list of synthetic flavouring substances permitted in the United States, and the carriers and solvents used with them. Like the natural flavour listing, it is the reason a label can say artificial flavour without saying which.

Where it is and isn’t permitted

What it is made from

Individually synthesised compounds, most of which also occur in nature. A synthetic and a natural version of the same compound are chemically identical; the distinction is regulatory and about the route, not the molecule.
