Acid Yellow 7

Description:
Acid Yellow 7, also known as Acid Yellow 23 or by its chemical name, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. It is characterized by its bright yellow color and is soluble in water, making it suitable for dyeing processes. The chemical structure of Acid Yellow 7 features an azo group (-N=N-), which is responsible for its vibrant coloration. This dye is often utilized in the food industry as a colorant, although its use is regulated in many countries due to potential health concerns associated with azo dyes. Acid Yellow 7 is known for its stability under normal conditions, but it may degrade when exposed to strong acids or bases. Additionally, it is important to handle this substance with care, as some azo dyes can release aromatic amines, which are considered hazardous. Overall, Acid Yellow 7 is a versatile dye with specific applications, but its safety and regulatory status should always be considered in its use.
