12226-03-8 Usage
General Description
Reactive Red 2 is a synthetic azo dye commonly used in the textile industry to color cotton, wool, silk, and other natural fibers. It is classified as a reactive dye, meaning it forms a covalent bond with the fibers, resulting in excellent wash and light fastness. However, Reactive Red 2 has been found to be toxic to aquatic organisms and may cause long-term adverse effects in the environment. In addition, exposure to the dye has been linked to skin and eye irritation in humans. Due to these potential health and environmental hazards, there have been efforts to regulate and restrict the use of Reactive Red 2 in various countries.
