CAS 1064-48-8

C.I. Acid Black 1

Description:

C.I. Acid Black 1, with the CAS number 1064-48-8, is a synthetic dye primarily used in the textile industry for dyeing wool, silk, and nylon. It belongs to the class of azo dyes, characterized by the presence of one or more azo groups (-N=N-), which contribute to its vibrant coloration. This dye exhibits excellent solubility in water, making it suitable for various dyeing processes. Acid Black 1 is known for its dark black hue and good lightfastness, although its fastness properties can vary depending on the substrate and dyeing conditions. In addition to its application in textiles, it may also be utilized in other industries, such as food and cosmetics, although its use in these areas is subject to regulatory scrutiny due to potential health concerns associated with azo dyes. Safety data indicates that while it may pose some risks, particularly in terms of skin irritation and potential carcinogenicity, proper handling and usage guidelines can mitigate these hazards.
