Disperse blue dyes are blue-colored disperse dyes. Disperse dyes are used to color textiles. Disperse blue dyes are used to produce blue and other dark colors. Like other disperse dyes, they are only slightly soluble in water. However, they can be a source of water pollution.

Disperse blue dyes, especially Disperse Blue 106 and Disperse Blue 124, have a higher than usual prevalence of textile dermatitis. This means that people who are allergic to the dyes may develop allergic symptoms (e.g., a rash) when they wear clothes that have been colored with these dyes.

Types

There are hundreds of disperse blue dyes. This table lists only a few. Some disperse dyes are also solvent dyes; for example, Disperse Blue 1 is the same chemical as Solvent Blue 18.

Disperse Blue 106 12223-01-7 Textile allergy, water pollution
Disperse Blue 124 61951-51-7 Textile allergy, water pollution
Disperse Blue 165 Cyano-substituted azo dye
Disperse Blue 183 Cyano-substituted azo dye Water pollution
Disperse Blue 257 Cyano-substituted azo dye
Disperse Blue 291 Water pollution
Disperse Blue 373 Azo dye Water pollution

Uses

Disperse blue dyes are used for dyeing synthetic fibers, such as fabric made from nylon or polyester.

Allergies

Some patch testing kits for allergens include a mix of Disperse Blue 106 and Disperse Blue 124, and other colors can be tested if a textile dye allergy is suspected. Treatment mostly involves not wearing dark-colored synthetic clothing.
