CAS 4680-78-8

Acid Green

Description:

Acid Green, with the CAS number 4680-78-8, is a synthetic dye commonly used in various applications, including textiles, food, and cosmetics. It belongs to the class of acid dyes, which are characterized by their solubility in water and their ability to bond with positively charged substrates, such as proteins and polyamide fibers. Acid Green is known for its vibrant green color and is often utilized in the dyeing of wool, silk, and nylon. The dye exhibits good lightfastness and washfastness, making it suitable for applications where durability is essential. However, like many synthetic dyes, it may pose environmental and health concerns, necessitating careful handling and disposal. Additionally, Acid Green can be subject to regulatory scrutiny due to potential toxicity and allergenic properties. As with all chemical substances, proper safety measures should be observed when working with Acid Green to mitigate any risks associated with exposure.
