ACID BLACK 52

Description

Acid Black 52, also known as C.I. 15711, is a synthetic dye widely used in the haircare industry. This water-soluble compound belongs to the azo dye family and is characterized by its intense black color. In hair coloring applications, Acid Black 52 provides deep, long-lasting black shades and is particularly effective in semi-permanent and temporary hair dye formulations.

The dye molecules in Acid Black 52 are designed to penetrate the hair shaft, adhering to the cortex without permanently altering the hair's structure. This property makes it an ideal choice for clients seeking temporary or semi-permanent color changes. Acid Black 52 exhibits good color fastness and resistance to fading, ensuring that the black hue remains vibrant for an extended period.

When formulating with Acid Black 52, it's essential to consider its pH sensitivity. The dye performs optimally in slightly acidic environments, typically between pH 4.5 and 6.5. This pH range also aligns well with the natural pH of hair, minimizing potential damage to the hair cuticle during the coloring process. As with all hair dyes, patch tests are recommended to assess individual sensitivity before full application.
