Abstract
Disperse Blue 106 and Disperse Blue 124 seem today often to be responsible for textile contact dermatitis; Menezes Brandao et al. (8) described 9 patients allergic to dark polyester blouses that contained Disperse Blue I 06. Lis boa et al. (9) studied 6 patients with textile contact dermatitis and 4 had positive patch tests to Disperse Blue 106. In another series (10), Disperse Blue 124 was positive in 23 of 41 patients with textile contact dermatitis. Balato et al. (II) also found, among 145 patients suspected of textile contact dermatitis, 12 positive to Disperse Blue 124, the highest number among the dyes tested (II). Massone et al. (I) described 2 cases of multiple azo dye sensitization: in both cases, patch tests to Disperse Blue 124, Disperse Red l and Disperse Orange 3 were positive. Our patient did not react to p-phenylenediamine, as in the cases of Hausen et al. (6). PPD is not always positive in cases of hypersensitivity to azo dyes (12); perhaps a dye mix would be useful to detect textile hypersensitivity (10, 13). A disperse mix containing Disperse Red, 1, Yellow 3, Orange 3 (0.25% each) and Disperse Blue 124 (0.1%) is used by Sertoli et al. (10). Some mixes contain up to 8 dyes, and seem potentially useful for detection of textile dye allergy (13).
