Acid Red 80

Description:
Acid Red 80, also known as Allura Red AC, is a synthetic azo dye commonly used in food, cosmetics, and pharmaceuticals for its vibrant red color. It is characterized by its solubility in water, which makes it suitable for various applications, particularly in aqueous solutions. The dye exhibits good stability under normal conditions, although it can be sensitive to light and heat, which may affect its color intensity over time. Acid Red 80 has a molecular formula that reflects its complex structure, featuring azo (-N=N-) linkages that contribute to its color properties. It is important to note that while Acid Red 80 is approved for use in many countries, it is subject to regulatory scrutiny due to potential allergic reactions in sensitive individuals. Additionally, its use is limited in certain applications due to health and safety considerations. Overall, Acid Red 80 is valued for its bright hue and versatility, but its application must be managed with awareness of safety guidelines and regulations.
