Uses

Used in Textile Industry:
3-[[2-[(N-Ethyl-N-phenylamino)sulfonyl]phenyl]azo]-4-hydroxy-1-naphthalenesulfonic acid sodium salt is used as a dye for coloring textiles. Its light fastness, soaping, and perspiration fastness properties make it an ideal choice for fabrics that require durability and resistance to fading.
Used in Cosmetic Industry:
3-[[2-[(N-Ethyl-N-phenylamino)sulfonyl]phenyl]azo]-4-hydroxy-1-naphthalenesulfonic acid sodium salt is used as a colorant in cosmetics, such as lipsticks and blushes, due to its vibrant red-orange hue and stability in various conditions.
Used in Printing Industry:
3-[[2-[(N-Ethyl-N-phenylamino)sulfonyl]phenyl]azo]-4-hydroxy-1-naphthalenesulfonic acid sodium salt is used as an ink additive for printing on various surfaces. Its resistance to oxygen bleaching and seawater makes it suitable for outdoor applications and materials that may come into contact with water.
Used in Plastics and Polymers Industry:
3-[[2-[(N-Ethyl-N-phenylamino)sulfonyl]phenyl]azo]-4-hydroxy-1-naphthalenesulfonic acid sodium salt is used as a colorant in the production of colored plastics and polymers. Its light fastness and stability properties ensure that the color remains vibrant and resistant to fading over time.
