Can 2,6-Xylenol be labeled natural?
Nature makes 2,6-Xylenol, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial 2,6-Xylenol, same molecule. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic 2,6-Xylenol 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
