Acid Orange 67

Description:

Acid Orange 67, with the CAS number 12220-06-3, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. It is characterized by its vibrant orange color, which results from the presence of azo functional groups (-N=N-). This dye is water-soluble, making it suitable for use in aqueous dyeing processes. Acid Orange 67 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 harmful. Its chemical structure typically includes sulfonic acid groups, enhancing its solubility and affinity for fibers. Safety data sheets indicate that it should be handled with care, as it may cause skin irritation or allergic reactions in sensitive individuals. Overall, Acid Orange 67 is an important dye in the industry, valued for its color properties and versatility, while also necessitating careful handling and consideration of environmental impact.
