Usage

Uses

Used in Textile Industry:
Acid Yellow 220 is used as a dye for coloring textiles due to its bright yellow color, solubility in water, and good light and wash fastness properties. It provides a vibrant appearance to fabrics and ensures color retention during washing and exposure to light.
However, it is important to note that Acid Yellow 220 is toxic to aquatic organisms and can cause harm if it enters the environment. Therefore, strict regulations and guidelines are in place for the handling and disposal of this dye to minimize its environmental impact.
