2-NITRO-N-HYDROXYETHYL-P-ANISIDINE

Description

2-Nitro-N-hydroxyethyl-p-anisidine is a synthetic hair dye ingredient primarily used in semi-permanent and demi-permanent hair coloring products. This compound belongs to the class of nitro dyes, known for their ability to impart vibrant, long-lasting color without the need for a developer or oxidizing agent. It typically produces warm, reddish-brown to copper tones in hair.

The molecule's structure allows it to penetrate the hair shaft and bond with the keratin proteins, resulting in color that gradually fades over multiple washes. This characteristic makes it suitable for clients seeking temporary color changes or those wanting to experiment with new shades without long-term commitment. 2-Nitro-N-hydroxyethyl-p-anisidine is often combined with other dye molecules to create a wide range of hues and achieve desired color results.

While effective as a colorant, this ingredient requires careful formulation and usage due to its potential for skin sensitization in some individuals. Professional application and adherence to recommended concentrations are essential to minimize risks. Additionally, patch testing is advised before use to identify any potential allergic reactions.
