3-NITRO-P-HYDROXYETHYLAMINOPHENOL

Description

3-Nitro-p-hydroxyethylaminophenol is a synthetic dye molecule commonly used in hair coloring formulations. This compound belongs to the family of nitro dyes, which are known for their ability to impart vibrant and long-lasting color to hair fibers. Its chemical structure consists of a phenol ring substituted with a nitro group and a hydroxyethylamino group, allowing it to penetrate the hair shaft and bond with keratin proteins.

When applied to hair, 3-nitro-p-hydroxyethylaminophenol typically produces warm reddish-brown to copper tones. It is often combined with other dye molecules to achieve a wide range of color results. This ingredient is particularly effective in covering gray hair due to its strong coloring properties.

Safety assessments have shown that 3-nitro-p-hydroxyethylaminophenol is generally safe for use in hair dye formulations when applied according to manufacturer instructions. However, as with many hair dye ingredients, it may cause allergic reactions in some individuals. Patch testing is recommended before use. Hair care professionals should be aware of its potential for skin staining and take appropriate precautions during application.
