Is Allura-red-Ac used in cosmetics products?

This dye is widely used to enhance the color of cosmetics such as foundation, eye shadow, lipstick, and other forms of lipstick. It has been determined to be safe for use around the eyes and is occasionally used in eyeliner and mascara. Because this color is primarily generated from petroleum, it is not commonly seen in natural or sensitive skin products. Non-comedogenic cosmetics, on the other hand, can contain this component because it has not been proven to clog pores.
