Can Undecyl alcohol be labeled natural?
Nature makes undecyl alcohol, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial undecyl alcohol, same molecule. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
