DISPERSE BLUE 7

Description

Disperse Blue 7, also known as CI 62500, is a synthetic blue dye commonly used in haircare formulations. This azine compound belongs to the disperse dye family, characterized by its low water solubility and ability to penetrate hydrophobic fibers. In hair coloring products, Disperse Blue 7 provides vibrant blue hues and is often combined with other dyes to create a range of cool-toned shades.

The dye's molecular structure allows it to penetrate the hair shaft, resulting in longer-lasting color compared to surface-level temporary dyes. It is particularly effective on lighter hair bases, producing intense blue tones. Disperse Blue 7 is frequently used in semi-permanent and demi-permanent hair color formulations, as well as in temporary color sprays and mascaras.

While effective for hair coloring, Disperse Blue 7 requires careful formulation to ensure optimal performance and safety. It is important to note that some individuals may experience skin sensitization or allergic reactions to this dye. As with all hair colorants, patch testing is recommended before use. Formulators should also be aware of regulatory guidelines regarding its concentration in finished products to ensure compliance with safety standards.
