HC Yellow 5

Description:
HC Yellow 5, also known as Acid Yellow 23, is a synthetic azo dye commonly used in various applications, including food, textiles, and cosmetics. It is characterized by its bright yellow color, which results from the presence of azo groups (-N=N-) in its molecular structure. This compound is soluble in water, making it suitable for use in aqueous solutions. HC Yellow 5 is known for its stability under normal conditions, although it can be sensitive to light and heat, which may affect its color intensity over time. As an azo dye, it is subject to regulatory scrutiny due to potential health concerns associated with some azo compounds, including their potential to form carcinogenic amines upon degradation. Therefore, its use is regulated in many countries, particularly in food products. Overall, HC Yellow 5 is valued for its vibrant hue and versatility, but its safety profile necessitates careful consideration in its applications.
