P-METHYLAMINOPHENOL SULFATE

Description

P-Methylaminophenol sulfate, also known as Metol, is a potent reducing agent commonly used in hair coloring formulations. This synthetic organic compound plays a crucial role in the oxidative dyeing process, particularly in permanent hair color products. Its molecular structure allows it to effectively penetrate the hair shaft, where it interacts with other colorants and oxidizing agents to produce long-lasting color results.

In hair dye formulations, p-methylaminophenol sulfate functions as a primary intermediate, contributing to the development of various color shades, especially in the brown to black spectrum. It works synergistically with other dye precursors and couplers to create a wide range of color options. The compound's ability to rapidly oxidize in the presence of hydrogen peroxide makes it an efficient choice for achieving desired hair color outcomes.

While effective in hair coloring applications, p-methylaminophenol sulfate requires careful handling due to its potential for skin sensitization. Manufacturers must adhere to strict concentration limits and safety guidelines when incorporating this ingredient into hair dye products. Additionally, patch testing is recommended for consumers to minimize the risk of allergic reactions.
