CAS 6473-13-8

Direct Black 22

Description:

Direct Black 22, with the CAS number 6473-13-8, is a synthetic azo dye primarily used in the textile industry for dyeing cotton and other cellulose fibers. This dye is characterized by its deep black color and excellent lightfastness, making it suitable for applications requiring durability. It is soluble in water, allowing for easy application in dyeing processes. However, like many azo dyes, Direct Black 22 may raise environmental and health concerns due to the potential release of aromatic amines upon degradation. Its chemical structure typically includes multiple aromatic rings and functional groups that contribute to its color properties. Safety data sheets indicate that it should be handled with care, as it may cause skin irritation or allergic reactions in some individuals. Regulatory frameworks in various regions may impose restrictions on its use due to environmental considerations, emphasizing the importance of responsible handling and disposal practices in industrial applications.
