Is ci77510 vegan?

CI 77510 is the Color Index designation for ferric ferrocyanide, an inorganic dark blue pigment commonly known as Prussian blue. It is manufactured industrially through chemical synthesis by reacting soluble iron salts, such as ferrous sulfate, with sodium or potassium ferrocyanide, followed by an oxidation step to yield a water-insoluble mineral powder. This colorant is predominantly listed on the ingredient labels of cosmetics and personal care items like eye makeup, bath products, and soaps, though it can also be found in food contact materials and industrial dyes.

CI 77510 is vegan because it is derived exclusively from synthetic mineral compounds. The production process relies entirely on inorganic mineral salts and chemical reagents, with no animal tissues, animal byproducts, or animal-derived processing aids used at any stage of manufacturing. Because it contains no animal-derived components, CI 77510 is suitable for a vegan lifestyle.
