4-AMINO-2-NITROPHENOL

Description

4-Amino-2-nitrophenol is a synthetic organic compound widely used in the hair dye industry. This potent colorant is known for its ability to impart rich, warm tones to hair, particularly in shades of red and brown. The molecule's structure allows it to penetrate the hair shaft effectively, resulting in long-lasting color.

As a semi-permanent dye ingredient, 4-amino-2-nitrophenol does not require a developer to work, making it suitable for gentler coloring processes. It is often combined with other dye molecules to create a wide range of hair color shades. The compound's stability ensures color retention through multiple washes.

While effective for hair coloration, 4-amino-2-nitrophenol is subject to regulatory limits due to potential skin sensitization concerns. It is typically used in concentrations below 3% in finished hair dye products. Manufacturers must adhere to safety guidelines and include appropriate warnings on product labels.

When formulating with 4-amino-2-nitrophenol, it's crucial to consider its solubility properties and potential interactions with other ingredients to ensure optimal performance and safety in hair dye formulations.
