Acid Red 18 can be used for dyeing wool, silk, nylon and direct printing of fabrics. Because the dyeing fastness and evenness are poor, the color light is not as bright as acid red G, so wool textiles are less used. Acid Red 18 can also be used to color leather, paper, wood products, plastics, inks, cosmetics, medicine, food, etc.
