Popular questions

Is yellow 6 harmful?
At approved food-use levels, Yellow 6 (Sunset Yellow FCF/E110) is considered safe by regulators such as the FDA, EFSA, and JECFA. A small number of people may have hypersensitivity reactions, and the EU requires a warning about possible effects on activity and attention in children.
What is yellow 6 made of?
It’s a synthetic, petroleum‑derived azo dye—the disodium salt of a sulfonated naphthalene azo compound—and is sometimes used in an insoluble aluminum “lake” form.
Is yellow 6 bad?
For most people it isn’t considered harmful at typical dietary intakes, which are well below regulatory acceptable daily intakes. Those with sensitivities (e.g., to azo dyes or aspirin) or concerned about children’s behavior may choose to limit it.
What does yellow 6 do to your body?
It provides color only and has no nutritional function; most is not absorbed and is excreted, though gut bacteria can metabolize small amounts. In susceptible individuals it can trigger allergic‑like reactions, and some children may show small, transient changes in activity or attention.
Does yellow 6 cause cancer?
Current evidence does not show that Yellow 6 causes cancer at permitted food-use levels, and regulators have not found it to be carcinogenic within established limits. Potential trace contaminants are strictly controlled to minimize any cancer risk.
