CI 13015
What is CI 13015?
CI 13015 is a synthetic organic colorant classified under the Colour Index as an acid azo dye, chemically structured with a chromophore that enables light absorption in the visible spectrum. Originating from industrial chemical synthesis, it produces a bright yellow shade. In cosmetic formulations, particularly rinse-off products such as shampoos, bath gels, soaps, and some hair colorants, it functions by dissolving in aqueous bases to deliver even color dispersion without sedimentation. This ensures product aesthetics remain stable during storage and use. Its water solubility facilitates integration into emulsions and gels, enhancing visual appeal while maintaining formulation clarity. Regulatory databases like CosIng list it solely as a colorant with no additional functions, emphasizing its role in achieving precise hues across production batches.
