CAS 6358-80-1

Acid black 94

Description:

Acid Black 94, with the CAS number 6358-80-1, is a synthetic azo dye primarily used in the textile industry for dyeing wool, silk, and nylon. It is characterized by its dark black color and excellent lightfastness, making it suitable for applications requiring durability. The dye is soluble in water, allowing for easy application in dyeing processes. Acid Black 94 is known for its ability to produce deep shades and is often used in combination with other dyes to achieve specific color effects. However, like many azo dyes, it may raise environmental and health concerns due to the potential release of aromatic amines upon degradation. Safety data sheets recommend handling it with care, as it may cause skin and eye irritation. Regulatory frameworks in various regions may impose restrictions on its use, particularly in consumer products, due to potential toxicity. Overall, Acid Black 94 is valued for its coloring properties but requires careful management to mitigate health and environmental risks.
