Beschreibung
Disperse orange 3 is an azo dye which can induce
contact dermatitis in workers in the textile industry.
Patch tests are frequently positive (about 30%) in
hairdressers with a hand dermatitis. It is probably an
indicator of contact sensitization to PPD, but disperse
orange 3 can also be found in so me semipermanent
hair dyes.
Chemische Eigenschaften
red to dark brown powder
Verwenden
Disperse orange 3 is used as a dye in acetate, nylon, silk, wool, and cotton; stocking dye.
synthetische
4-Nitrobenzenamine diazo, with aniline base armour sulfonic acid coupling, and sodium hydroxide solution to boil, then a sulfonic acid hydrolysis off base.
Definition
ChEBI: Azobenzene substituted at the phenyl 4-positions by an amino and a nitro group.
Allgemeine Beschreibung
Disperse Orange 3 (DO3) is a monoazo dye, which contains 90% dye content plus dispersing agents and surfactants. It has two aromatic rings with an amino group on one of the rings and the other is substituted with a nitro group. It shows an absorption peak majoring at 415 nm.
Kontakt-Allergie
Disperse Orange 3 is an azo dye that can induce contact
dermatitis in workers in the textile industry. It is
positive in a great majority of PPD-positive people,
because of hydrolysis in the skin into PPD. Disperse
Orange 3 can also be found in some semipermanent
hair dyes.
