C.I. Acid Green 16

Description:

C.I. Acid Green 16, with the CAS number 12768-78-4, is a synthetic dye primarily used in the textile and paper industries. It belongs to the class of acid dyes, which are characterized by their solubility in water and ability to bond with positively charged substrates, such as proteins and polyamide fibers. This dye exhibits a vibrant green color and is known for its good lightfastness and washfastness properties, making it suitable for applications where color retention is essential. C.I. Acid Green 16 is often utilized in the dyeing of wool, silk, and nylon, as well as in various cosmetic formulations. However, like many synthetic dyes, it may pose environmental and health concerns, necessitating careful handling and disposal. Regulatory assessments often evaluate its safety profile, including potential allergenic effects and environmental impact. Overall, C.I. Acid Green 16 is valued for its coloring properties but requires responsible use in industrial applications.
