Red Dye No. 3 is a synthetic dye commonly used to color food, cosmetics, and pharmaceuticals. It is known for its bright red hue and is often found in products like candies, beverages, and baked goods. The dye is made from petroleum-based chemicals and is classified as a color additive. In the United States, Red Dye No. 3 was approved by the Food and Drug Administration (FDA) for use in food products. However, concerns about its safety have led to restrictions on its use in certain applications, particularly in cosmetics, due to potential health risks.
