DISPERSE BLUE 1

Description

Disperse Blue 1, also known as CI 64500, is a synthetic anthraquinone dye widely used in the cosmetic and personal care industry, particularly in haircare products. This vibrant blue colorant is prized for its ability to impart a rich, deep blue hue to various hair dye formulations and temporary hair color products.

The dye's molecular structure allows it to penetrate the hair shaft, providing longer-lasting color results compared to surface-level pigments. Disperse Blue 1 is often combined with other dyes to create a range of blue-based shades, from navy to teal. Its stability in various product matrices and resistance to fading make it a popular choice for both professional and at-home hair coloring applications.

While effective as a colorant, it's important to note that Disperse Blue 1 has been associated with skin sensitization in some individuals. As a result, patch testing is recommended before use, especially for those with sensitive skin or a history of allergic reactions to hair dyes. Formulators must adhere to regulatory guidelines regarding concentration limits to ensure product safety and compliance.
