Red dye 40 (Allura Red AC)

Allura Red AC, or red dye 40, is a synthetic dye commonly found in processed foods, produce, and makeup products. This specific dye, despite common misconceptions, is synthetic and is not made of bugs. Instead, red dye 40 is made from ingredients derived from petroleum or crude oil. Red dye 40's chemical formula is C18H14N2Na2O8S2 with a melting point of 0 degrees Celsius and a boiling point of 100 degrees Celsius (when mixed with water). Red dye 40 is something that people come in contact with every day. To make foods look more appealing the dye is added, even in produce! Certain makeups will also use red dye 40 to achieve a vibrant red color. So, next time you eat an apple, dive into your favorite bag of chips, or put on your bright red lipstick, ask yourself if it could contain red dye 40 (the answer is probably yes).
