4-NITRO-M-PHENYLENEDIAMINE

Description

4-Nitro-m-phenylenediamine is a synthetic organic compound commonly used in hair dye formulations. This aromatic diamine serves as a crucial intermediate in the production of oxidative hair colorants. Its chemical structure consists of a benzene ring with an amino group (-NH2) and a nitro group (-NO2) attached.

In hair dye applications, 4-nitro-m-phenylenediamine acts as a precursor molecule, which, when combined with an oxidizing agent, undergoes a series of chemical reactions to form larger, colored molecules. These newly formed pigments become trapped within the hair shaft, providing long-lasting color.

This compound is particularly effective in creating warm brown to reddish-brown shades. It is often used in combination with other dye precursors to achieve a wide range of hair color results. Due to its strong coloring properties, 4-nitro-m-phenylenediamine is typically used in small concentrations within hair dye formulations.

It's important to note that this ingredient may cause allergic reactions in some individuals. As with all hair dye products, a patch test is recommended before use to check for potential sensitivities or adverse reactions.
