Synthetic dye

Plain-language explanation

E133, known as Brilliant Blue FCF, is a synthetic triarylmethane dye used to give foods and beverages a bright blue color. It is produced entirely through chemical synthesis from petroleum-derived precursors, meaning it does not come from any animal source. Because it is an artificial chemical with no animal or alcohol involvement, it is universally considered halal by major certification bodies including JAKIM, MUI, MUIS, ESMA, and HFA. Its halal status is straightforward and does not depend on the source, as the manufacturing process is consistently synthetic. Muslims can safely consume products containing this ingredient without concern for its halal compliance.
