Naphthol AS is a coupling agent in cotton dyeing, inducing occupational dermatitis or contact allergy in consumers in contact with cotton-dyed clothing. It has been indirectly reported as a cause of occupational allergy due to its coupling with Diazo Component 51, or as a crosssensitizer or sensitizer associated with Pigment Red 23 in red parts of tattoos. Pigmented contact dermatitis is usual in patients with a high phototype.
