Black 7 Dye
Black 7 Dye, also known as CI 26150 or D&C Black No. 7, is a synthetic black pigment primarily composed of carbon-based aromatic compounds. It is a high-purity, oil-dispersible colorant derived from oxidized aniline and related intermediates. Known for its intense black shade and strong tinting strength, Black 7 Dye is widely used in the cosmetics, personal care, pharmaceutical, and specialty colorant industries.
This dye is chemically stable, lightfast, and compatible with oils, esters, waxes, and synthetic bases, making it suitable for both leave-on and rinse-off formulations. It is particularly favored in products requiring bold color expression, such as eye makeup, hair dyes, and tattoo inks. Surface-treated forms are also available to enhance dispersibility and formulation compatibility.
