O-AMINOPHENOL SULFATE

Description

O-Aminophenol Sulfate is a synthetic organic compound widely used in the hair coloring industry. This water-soluble, crystalline substance serves as a crucial precursor in the formation of various hair dyes, particularly those producing dark brown to black shades. Its chemical structure allows for efficient oxidation and coupling reactions, essential processes in permanent hair coloration.

In hair dye formulations, O-Aminophenol Sulfate acts as an intermediate, reacting with other components to create the final color molecules. It contributes to the development of long-lasting, vibrant hues and helps achieve uniform color distribution throughout the hair shaft. This ingredient is often combined with hydrogen peroxide and other color developers to initiate the coloring process.

While effective for hair coloration, O-Aminophenol Sulfate requires careful handling due to its potential for skin and eye irritation. Formulators must adhere to regulatory guidelines regarding its concentration in hair dye products. When used as directed in properly formulated hair colorants, it provides reliable and consistent results. However, patch testing is recommended before use to check for potential allergic reactions.
