2-CHLORO-6-ETHYLAMINO-4-NITROPHENOL

Description

2-Chloro-6-ethylamino-4-nitrophenol is a synthetic hair dye ingredient used in semi-permanent and permanent hair coloring formulations. This compound belongs to the nitrophenol family and is known for its ability to impart red to reddish-brown hues to hair. It is typically used in combination with other dye precursors to achieve a wide range of color results.

The molecule's structure allows it to penetrate the hair shaft and react with oxidizing agents, forming larger color molecules that remain trapped within the hair cuticle. This process ensures long-lasting color results that resist fading through multiple washes. 2-Chloro-6-ethylamino-4-nitrophenol is particularly effective in covering gray hair and providing vibrant, intense color outcomes.

While effective as a hair dye, this ingredient requires careful formulation and application due to its potential for skin sensitization. It is subject to regulations in various countries, with maximum allowed concentrations typically ranging from 2% to 4% in ready-to-use hair dye products. Proper patch testing is recommended before use to minimize the risk of allergic reactions. When used as directed in approved formulations, 2-chloro-6-ethylamino-4-nitrophenol contributes to achieving desired hair color results with reasonable safety.
