C.I. Acid Blue 90

Description:
C.I. Acid Blue 90, also known by its chemical name as Disodium 4-amino-5-hydroxy-3-(2-sulfo-4-sulfophenylazo) naphthalene-1,7-disulfonate, is a synthetic dye primarily used in the textile and food industries. It belongs to the azo dye class, characterized by the presence of one or more azo groups (-N=N-), which contribute to its vibrant color. This dye is soluble in water, making it suitable for applications requiring aqueous solutions. C.I. Acid Blue 90 exhibits good lightfastness and stability under various conditions, although its performance can vary depending on the substrate and application method. It is important to note that, like many azo dyes, there are concerns regarding its potential toxicity and environmental impact, leading to regulatory scrutiny in certain regions. Safety data sheets typically recommend handling it with care, as it may cause irritation upon contact with skin or eyes. Overall, C.I. Acid Blue 90 is valued for its coloring properties but must be managed responsibly in industrial applications.
