2-AMINO-5-NITROPHENOL
Description
2-Amino-5-nitrophenol is a synthetic organic compound commonly used in hair dye formulations. This aromatic molecule functions as a direct dye, providing vibrant red to copper tones in hair coloring products. Its chemical structure allows for effective penetration of the hair shaft, resulting in long-lasting color.
The compound is typically used in combination with other dye precursors to achieve a wide range of hair color shades. It is particularly effective in creating warm, reddish hues and enhancing the depth of brown hair colors. 2-Amino-5-nitrophenol is known for its stability and resistance to fading, contributing to the durability of hair dye formulations.
In terms of safety, this ingredient has been extensively studied and is approved for use in hair dyes by regulatory bodies such as the European Commission and the FDA. However, as with many hair dye components, it may cause skin sensitization in some individuals. Proper patch testing is recommended before use.
Formulators often incorporate 2-amino-5-nitrophenol in oxidative and semi-permanent hair color products, typically at concentrations between 0.1% and 3%, depending on the desired color intensity and formulation type.
