C.I. Mordant Blue 29

Description:
C.I. Mordant Blue 29, with the CAS number 1667-99-8, is a synthetic dye primarily used in textile applications, particularly for dyeing wool and silk. It belongs to the class of mordant dyes, which require a mordant to fix the dye onto the fabric, enhancing color fastness. This dye exhibits a deep blue hue and is characterized by its complex molecular structure, which includes azo groups that contribute to its chromophoric properties. Mordant Blue 29 is known for its good light and wash fastness, making it suitable for various applications in the dyeing industry. Additionally, it has been studied for its environmental impact, as some azo dyes can release harmful amines upon degradation. Safety data indicates that while it is generally considered safe for use in textiles, appropriate handling and disposal measures should be observed to minimize environmental and health risks. Overall, C.I. Mordant Blue 29 is valued for its vibrant color and durability in dyed materials.
