5-AMINO-4-FLUORO-2-METHYLPHENOL SULFATE

Description

5-Amino-4-fluoro-2-methylphenol sulfate is a potent hair dye precursor used in professional and at-home hair coloring products. This synthetic compound belongs to the class of para-phenylenediamine (PPD) derivatives, known for their ability to create long-lasting, vibrant hair colors. When combined with an oxidizing agent, typically hydrogen peroxide, it undergoes a chemical reaction that produces melanin-like pigments within the hair shaft.

This ingredient is particularly effective in creating warm brown and red tones, offering excellent gray coverage and color persistence. Its molecular structure allows for better penetration into the hair cortex, resulting in more uniform and intense coloration compared to some traditional dye precursors. The fluorine atom in its structure contributes to enhanced stability and color fastness.

While 5-amino-4-fluoro-2-methylphenol sulfate is generally considered safe when used as directed, it may cause allergic reactions in some individuals. Patch testing is recommended before use, especially for those with sensitive skin or a history of allergic reactions to hair dyes. This compound is typically used in concentrations ranging from 0.1% to 2.0% in final hair color formulations, depending on the desired shade intensity and product type.
