DISPERSE BLUE 1 Usage And Synthesis

Chemical Properties

blue-black crystalline powder

Uses

Disperse blue 1 has been used in hair-color formulations and to color fabrics and plastics. Commercial preparations of disperse blue 1 contain approximately equal amounts of dyestuff and lignosulfonate dispersants. In the mid 1980s, it was reported that semi-permanent hair-color formulations commonly contained disperse blue 1 at concentrations of less than 1% (NTP 1986). Disperse blue 1 is used as a fabric dye for nylon, cellulose acetate and triacetate, polyester, and acrylate fibers and for surface dyeing of thermoplastics, as a solvent dye in cellulose acetate plastics, and to dye fur and sheepskins (NTP 1986, IARC 1990, HSDB 2009). It is also used in some personal-care products, such as hair mousse and toothpaste (HPD 2009).

Uses

Disperse Blue 1 is a textile disperse dye. It is an anthraquinone dye used at low levels in semipermanent hair color formulations. Dyes and metabolites, Environmental Testing.

Definition

ChEBI: Disperse Blue 1 is an anthraquinone.

General Description

Blue-black microcrystalline powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

An amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition DISPERSE BLUE 1 emits toxic fumes of nitrogen oxides.

Fire Hazard

Flash point data for DISPERSE BLUE 1 are not available; however, DISPERSE BLUE 1 is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Carcinogenicity

Disperse blue 1 is reasonably anticipated to be a human carcinogen based on (1) sufficient evidence of carcinogenicity from studies in experimental animals and (2) the fact that it belongs to a welldefined, structurally related class of anthraquinones whose membersare listed in the Report on Carcinogens as reasonably anticipated to be human carcinogens.
