CarmineColorant
Insect-derived (not vegan/vegetarian) and a recognized cause of IgE-mediated allergic reactions, including documented anaphylaxis. The FDA mandated explicit 'carmine'/'cochineal extract' labeling in 2011 specifically because of these reactions. Not toxic to the general population, but a genuine allergen with no health benefit; plant pigments achieve the same color.

Widely used emulsifier derived from soybeans
