HC ORANGE NO. 2

Description

HC Orange No. 2, also known as 1-(2-Hydroxyethylamino)-4-nitrobenzene, is a synthetic dye widely used in semi-permanent hair coloring products. This orange-red compound is particularly effective in imparting warm, coppery tones to hair. Its molecular structure allows it to penetrate the hair shaft, providing longer-lasting color compared to temporary dyes.

The ingredient is approved for use in hair colorants in various countries, including those in the European Union, with specific concentration limitations. HC Orange No. 2 works by interacting with the keratin proteins in hair, creating a temporary bond that results in color change. It is often combined with other dyes to achieve a broader range of shades.

While generally considered safe when used as directed, some individuals may experience skin sensitization or allergic reactions. Patch testing is recommended before use. The compound's stability in formulations and its ability to provide vibrant results without excessive damage to the hair structure make it a popular choice among haircare formulators. However, as with all hair dyes, prolonged or frequent use may lead to some drying or weakening of the hair shaft over time.
