What is CI 15880 used for?
CI 15880 is a cosmetic colorant that imparts a vibrant red color or pink hues to formulations - making it a popular choice in products like lipsticks, blushes, nail polishes, and eyeshadows. Its strong pigmentation allows for effective coloring even at low concentrations. Additionally, CI 15880 is employed in some skincare products to provide a slight tint. Due to its stability and resistance to fading, it is favored in both water-based and oil-based formulations. Overall, this ingredient is used to provide a red color and enhance the visual appeal of a wide range of beauty products.
Origin
CI 15880 is synthesized through a diazotization reaction, where an aromatic amine is converted into a diazo compound. This compound undergoes a coupling reaction with another aromatic compound to form the azo dye. The process involves precise control of temperature and pH to ensure high purity and color intensity. Once synthesized, the dye is purified and processed into a fine powder for use in cosmetics.

Safety Profile
CI 15880 is generally considered safe for external use at low concentrations. However, it has a potential for toxicity and skin irritation, necessitating the need for patch tests. It is important to note that in the U.S., this ingredient has not been approved for use in products applied to the lips or around the eyes. Proper manufacturing, regulations, and low concentrations make CI 15880 safer for use. Additionally, this colorant is not environmentally friendly as it is not easily biodegradable and can persist in the environment for long durations.
