Direct Orange 26

Description:

Direct Orange 26, with the CAS number 3626-36-6, is a synthetic azo dye commonly used in the textile industry for dyeing cellulose fibers. It is characterized by its vibrant orange color and is soluble in water, making it suitable for various dyeing processes. The dye is known for its good lightfastness and moderate wash fastness, which are important properties for maintaining color integrity during laundering. Direct Orange 26 is typically applied in a direct dyeing process, where it bonds directly to the fabric without the need for a mordant. However, like many azo dyes, it may raise environmental and health concerns due to the potential release of aromatic amines upon degradation. Safety data sheets recommend handling it with care, as it may cause skin irritation or allergic reactions in some individuals. Overall, Direct Orange 26 is valued for its color properties in industrial applications, but its use is subject to regulatory scrutiny regarding environmental impact and safety.

Direct Orange 26, Technical grade Dye content

CAS: 3626-36-6

Direct Orange 26 is a reactive dye that has been used for wastewater treatment. It is a cationic surfactant and can be used in the presence of other anionic, non-ionic, or cationic detergents. Direct Orange 26 has been shown to have toxicological effects on ganoderma lucidum and bacterial strains. Direct Orange 26 binds to copper ions, forming a complex that produces reactive oxygen species. These reactive oxygen species are responsible for the oxidative damage observed in cellular studies using mammalian cells.
