C.I. Reactive Yellow 81, with the CAS number 59112-78-6, is a synthetic dye commonly used in textile applications for coloring fabrics, particularly cotton and other cellulose fibers. This dye belongs to the class of reactive dyes, which are characterized by their ability to form covalent bonds with the fiber, resulting in strong and durable coloration. Reactive Yellow 81 exhibits bright yellow hues and is known for its excellent lightfastness and washfastness properties, making it suitable for various dyeing processes. The dye is typically applied in an alkaline medium, which facilitates the reaction between the dye and the fiber. In terms of safety, like many synthetic dyes, it is essential to handle C.I. Reactive Yellow 81 with care, as it may pose health risks if inhaled or ingested, and appropriate safety measures should be taken during its use. Additionally, environmental considerations are important, as the disposal of dye effluents can impact aquatic ecosystems, necessitating proper treatment before release.
