5399-85-9 Usage
General Description
Sodium p-[(4-amino-1-naphthyl)azo]benzenesulphonate, also known as Sudan I, is an azo dye that is used primarily as a coloring agent. It is a synthetic substance that is commonly used to impart a deep red color to a variety of products, including textiles, plastics, and inks. However, due to its potential carcinogenic properties and links to various health risks, its use has been restricted or banned in many countries. The World Health Organization has classified Sudan I as a Group 3 carcinogen, meaning it is not classifiable as to its carcinogenicity to humans. Additionally, there have been concerns about its potential to cause skin irritation and allergic reactions. Due to these health concerns, efforts have been made to limit the availability and use of products containing Sudan I in order to protect public health and safety.
