HC YELLOW NO. 14

Description

HC Yellow No. 14 is a synthetic dye primarily used in semi-permanent hair coloring products. This water-soluble compound belongs to the azo dye family and is known for its ability to impart vibrant yellow to golden hues to hair. HC Yellow No. 14 is particularly effective in creating warm blonde shades and enhancing highlights in lighter hair colors.

The dye molecule is designed to penetrate the hair shaft, providing longer-lasting color compared to temporary dyes. It adheres to the hair's cortex without significantly altering the hair's natural structure. HC Yellow No. 14 is often combined with other dyes to achieve a wide range of color outcomes.

In formulations, HC Yellow No. 14 is typically used at concentrations between 0.1% to 2%, depending on the desired intensity of color. It performs optimally in slightly alkaline environments, which helps open the hair cuticle for better dye penetration. This ingredient is compatible with most common hair care ingredients and can be incorporated into various product types, including creams, gels, and liquids.

While generally considered safe for use in hair dyes, some individuals may experience skin sensitization. Patch testing is recommended before use.
