What it is
Yellow 6, also known as Sunset Yellow FCF, is a synthetic yellow azo dye. Titanium dioxide is a white mineral pigment. Both are used to add color to foods.
Why it's used
Yellow 6 provides a yellow to orange color, while titanium dioxide provides a bright white color. They are often used together or separately in baked goods, candies, beverages, and dessert toppings to make products visually appealing.
Health notes
Yellow 6 is an FDA-approved color additive. Titanium dioxide is also FDA-approved for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 6. Some studies have suggested a link between certain artificial food dyes, including Yellow 6, and hyperactivity in children, but the evidence is mixed. The WHO/IARC has not classified Yellow 6. EFSA has evaluated titanium dioxide and did not set a numeric limit (ADI not specified).
Allergen info
Not a major allergen. Yellow 6 and titanium dioxide are not derived from the 9 FDA major allergens. They do not contain gluten.
