General Description

Acid Yellow 220 is a bright yellow dye commonly used in the textile industry. It belongs to the class of synthetic organic dyes known as Azo dyes, which are characterized by a nitrogen double bond. Acid Yellow 220 is soluble in water and has good light and wash fastness properties, making it ideal for dyeing and printing of textiles. However, it is also known to be toxic to aquatic organisms and can cause harm if it enters the environment. As a result, strict regulations and guidelines are in place for the handling and disposal of Acid Yellow 220 to minimize its environmental impact.
