4-FLUORO-6-METHYL-M-PHENYLENEDIAMINE SULFATE

Description

4-Fluoro-6-methyl-m-phenylenediamine sulfate is a synthetic hair dye precursor used in permanent hair coloring products. This compound belongs to the family of aromatic diamines and is particularly effective in creating dark hair shades. Its molecular structure allows for efficient penetration into the hair shaft, where it reacts with an oxidizing agent to form larger, colored molecules.

The sulfate form of this compound enhances its solubility in aqueous solutions, making it easier to incorporate into hair dye formulations. It typically works in conjunction with other dye precursors to produce a wide range of color outcomes. The fluorine atom in its structure contributes to the stability of the molecule and can influence the final color tone.

When used in hair dye formulations, 4-fluoro-6-methyl-m-phenylenediamine sulfate undergoes oxidative coupling reactions, resulting in the formation of permanent color within the hair cortex. This process ensures long-lasting color results that resist fading from washing and environmental factors. However, as with many hair dye ingredients, it may cause allergic reactions in some individuals, necessitating patch testing before use.
