CAS 15792-50-4

Acid Orange 63

Description:

Acid Orange 63, with the CAS number 15792-50-4, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This dye is characterized by its vibrant orange color, which results from the presence of azo functional groups (-N=N-). Acid Orange 63 is water-soluble, making it suitable for use in aqueous dyeing processes. It exhibits good lightfastness and stability under acidic conditions, which is advantageous for its application in acidic dyeing environments. However, like many azo dyes, it may raise environmental and health concerns due to potential degradation products that can be toxic or carcinogenic. Therefore, its use is often regulated in many countries. The dye is typically applied to protein fibers, such as silk and wool, and can also be used in the coloration of paper and plastics. Proper handling and disposal practices are essential to mitigate any environmental impact associated with its use.
