Can 1-Hexadecanol be labeled natural?

Since 1-Hexadecanol is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when 1-Hexadecanol is synthesized. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic 1-Hexadecanol identical-to-natural.

United States
Natural or artificial, by process
European Union and UK
Natural only from natural material
Mercosur and Mexico
Natural or identical-to-natural

How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.

Sources and attribution. The identity and regulatory facts on this page are taken from the FDA Substances Added to Food inventory, a US government record, which lists this substance as CETYL ALCOHOL under CAS 36653-82-4 and carries its FEMA number, its JECFA flavor number and its 21 CFR citations. The inventory is searchable at FDA. FDA records its technical effect as flavoring agent or adjuvant.

A FEMA GRAS conclusion is reached by the Expert Panel of the Flavor and Extract Manufacturers Association of the United States, and the FEMA number names that conclusion. FEMA publishes its own entry for this substance in the FEMA Flavor Library, which is the authoritative record of what the Panel decided and is worth reading alongside this page.
