2-AMINO-4-NITROPHENOL SULFATE
Description
2-Amino-4-nitrophenol sulfate is a synthetic dye compound primarily used in hair coloring products. This potent colorant is known for its ability to impart vibrant red and orange hues to hair, making it a crucial ingredient in many semi-permanent and permanent hair dye formulations. The compound's molecular structure allows it to penetrate the hair shaft effectively, resulting in long-lasting color.
In hair dye applications, 2-amino-4-nitrophenol sulfate typically functions as an intermediate dye, meaning it reacts with other color components to produce the desired shade. Its sulfate form enhances water solubility, facilitating easier incorporation into various hair dye formulations. The ingredient is particularly effective in covering gray hair and creating intense, warm tones.
While 2-amino-4-nitrophenol sulfate is widely used in the hair coloring industry, it is important to note that some individuals may experience allergic reactions or skin sensitivity. As with all hair dye ingredients, patch testing is recommended before full application. Additionally, this compound is subject to regulatory limits in many countries due to its potential for skin irritation at high concentrations.
