2-Amino-6-Chloro-4-Nitrophenol

What is 2-Amino-6-Chloro-4-Nitrophenol?

2-Amino-6-chloro-4-nitrophenol is a synthetic organic compound belonging to the nitroaniline family of colorants. Characterized by its yellow hue, it functions as a direct dye in cosmetics, primarily hair care formulations. Unlike oxidative dyes, it does not require chemical reactions with hydrogen peroxide or ammonia; instead, it adheres physically to the hair cuticle, depositing color molecules that penetrate the shaft for visible tinting. Commonly found in shampoos, conditioners, and gels designed for temporary or semi-permanent hair coloring, it enables vibrant yellow tones, highlights, or subtle shifts without altering the hair's internal structure drastically. Its stability allows for gradual fading with washes, making it suitable for experimental or low-commitment color changes.
