CAS 1390-65-4: Carmine
Description:Carmine, with the CAS number 1390-65-4, is a natural red dye derived from the cochineal insect, specifically from the carminic acid extracted from the female cochineal. It is known for its vibrant red color and is widely used in food, cosmetics, and textiles. Carmine is classified as a color additive and is often labeled as E120 in the European Union. Its chemical structure is characterized by the presence of a chromophore that absorbs specific wavelengths of light, resulting in its distinctive hue. Carmine is water-soluble, which allows it to be easily incorporated into various products. However, it is important to note that some individuals may have allergic reactions to carmine, leading to its regulation in certain applications. Additionally, carmine is considered a vegan-unfriendly product due to its insect origin, prompting the search for synthetic alternatives in various industries. Overall, carmine is valued for its intense color and stability, making it a popular choice in many formulations.
