2-CHLORO-P-PHENYLENEDIAMINE

Description

2-Chloro-p-phenylenediamine is a synthetic organic compound commonly used in hair dye formulations. This para-substituted aromatic diamine serves as a key component in oxidative hair coloring systems, particularly for achieving dark shades and covering gray hair. Its chemical structure allows for efficient coupling with other dye precursors, resulting in the formation of complex color molecules within the hair shaft.

This ingredient is known for its ability to penetrate the hair cuticle and react with hydrogen peroxide to create long-lasting color. It offers superior color fastness and resistance to fading compared to many other hair dye ingredients. 2-Chloro-p-phenylenediamine is often used in combination with other dye precursors to achieve a wide range of hair colors and tones.

While effective for coloring, this compound requires careful handling and formulation due to its potential for skin sensitization. Proper patch testing is recommended before use, and it should be utilized within the concentration limits set by regulatory bodies. In recent years, research has focused on developing safer alternatives with similar efficacy to address concerns regarding skin irritation and allergic reactions associated with this ingredient.
