Is e131 patentblau v vegan?

E131 patentblau v is the German label term for Patent Blue V, a synthetic food coloring agent classified under European additive code E131. It is a dark blue triphenylmethane dye produced industrially through chemical synthesis using aromatic petroleum derivatives, specifically diethylaniline and benzaldehyde sulfonic acid. Manufacturers add this colorant to achieve a vivid sky-blue shade in processed items such as confectionery, hard candies, flavored syrups, soft drinks, ice pops, and cake decorations, as well as in cosmetic formulations and medical diagnostics.

This additive receives a vegan verdict because it is entirely synthetic and derived from mineral and petrochemical sources. No animal tissues, fluids, or animal-derived processing aids are used at any stage of its synthesis or refinement. Because its manufacturing pathway does not involve animal inputs or animal byproducts, foods containing E131 patentblau v are suitable for vegan diets.
