General Description

Acid Orange 156, also known as C.I. Acid Orange 156, is a synthetic azo dye commonly used in the textile industry to dye natural and synthetic fibers. It is a bright orange to red solid powder with the chemical formula C16H11N3O4S. Acid Orange 156 is water-soluble and is often applied to textiles by immersion or padding. It is known for its high color strength and good light fastness, making it a popular choice for a wide range of applications including clothing, upholstery, and home textiles. However, like many azo dyes, Acid Orange 156 has been found to have potential health and environmental concerns, leading to its regulation and restricted use in some regions.
