Disperse Violet 4, also known by its chemical name 1-amino-4-(methylamino)anthraquinone and identified by the Colour Index number CI 61105, is a synthetic dye primarily used in hair dyeing products. This vibrant violet dye is part of the anthraquinone family, a group of compounds known for their vivid colors and stability.
The history of Disperse Violet 4 in cosmetics dates back to the mid-20th century when synthetic dyes began to replace natural dyes due to their consistency and broader color range. Initially developed for the textile industry, its ability to impart a rich, long-lasting color made it a natural fit for hair dye formulations. Over time, it has become a staple in the cosmetic industry, particularly in products aimed at achieving bold and vibrant hair colors.
The production of Disperse Violet 4 involves a series of chemical reactions starting with anthraquinone, a naturally occurring compound found in some plants and fungi. Through a process of nitration, reduction, and methylation, anthraquinone is transformed into the final dye molecule. This synthetic route ensures a high degree of purity and consistency, which is crucial for cosmetic applications where precise color matching is essential.
