FD&C Yellow No.6 Color Index 15985

FD&C Yellow No. 6 is a synthetic food coloring, also known as Sunset Yellow FCF. It is an azo dye, meaning it is produced through chemical synthesis from petroleum-based raw materials. It provides an orange-yellow color to foods.

Manufacturers add FD&C Yellow No. 6 to give an orange-yellow color to a variety of foods and beverages. It is commonly found in products like snack foods, soft drinks, desserts, and candies to enhance their visual appeal.

FD&C Yellow No. 6 is an FDA-approved color additive for use in food. JECFA has evaluated it and set an acceptable daily intake. EFSA has also evaluated its safety. Some studies have suggested a possible link between synthetic food dyes, including Yellow No. 6, and hyperactivity in some children, though evidence remains mixed and not all studies have found a consistent link. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including FD&C Yellow No. 6, from food products.
