Is the vinyl aniline substance found in Clorets chewing gum, which is a Lebanese product, a forbidden alcoholic substance or a permissible amino acid?

The criterion for prohibiting or permitting a substance is whether it is intoxicating or harmful, or if it is derived from something Allah has forbidden to eat, such as pork or carrion. If the substance is free from all reasons for prohibition, then there is no objection to consuming foods that contain it.
