Can 1-Phenyl-3-methyl-3-pentanol be labeled natural?

The process decides for 1-Phenyl-3-methyl-3-pentanol. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic 1-Phenyl-3-methyl-3-pentanol is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
