4-AMINO-M-CRESOL

Description

4-Amino-m-cresol is a synthetic organic compound commonly used in hair dye formulations. This aromatic amine serves as a crucial intermediate in the production of oxidative hair colorants, particularly for achieving dark brown to black shades. Its chemical structure consists of an amino group and a methyl group attached to a phenol ring, giving it unique properties suitable for hair coloration.

In hair dye formulations, 4-amino-m-cresol acts as a precursor that undergoes oxidation when mixed with a developer, typically hydrogen peroxide. This reaction produces larger, colored molecules that penetrate the hair shaft and bond with the keratin structure, resulting in long-lasting color. The compound's ability to create intense, deep hues makes it a valuable ingredient in permanent hair color products.

While effective for hair coloration, 4-amino-m-cresol requires careful handling and formulation due to its potential for skin sensitization. Manufacturers must adhere to strict concentration limits and safety guidelines set by regulatory bodies to ensure product safety. Additionally, patch tests are recommended for consumers to check for potential allergic reactions before full application of hair dye products containing this ingredient.
