CI 73015, also known as Brilliant Blue FCF or Indigo Carmine, is a synthetic blue dye used extensively in cosmetics, skincare, and personal care products. This water-soluble colorant provides a vibrant blue shade and is often used in conjunction with other dyes to achieve various hues. In its pure form, CI 73015 appears as a fine, bright blue powder and is considered safe for use. With the chemical formula C37H34N2Na2O9S3, this ingredient is highly soluble in water making it easy to incorporate into water based formulations. It is commonly found in decorative cosmetics like eyeshadows and mascaras and is also added to shampoos, conditioners, and cleansers to enhance the visual of these products.

Origin
CI 73015 is synthesized through a multi-step chemical process. It begins with aromatic compounds, such as benzene derivatives, that undergo sulfonation, ethylation, and other chemical reactions to form the final dye structure. This process includes adding functional groups that enhance the color and water solubility. Once synthesized, the dye is purified, filtered, and dried.
