Can Cinnamyl benzoate be labeled natural?

The process decides for cinnamyl benzoate. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic cinnamyl benzoate is artificial. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic cinnamyl benzoate identical-to-natural.
