Sensitivity to a flame retardant, Tris(2,3-dibromopropyl)phosphate (Firemaster LVT 23 P).

Tris(2,3-dibromoprophyl) phosphate (TDB P) is marketed under many different trade names as a flame retardant, used in clothing and home furnishings. DTB P is chemically related to tricresylphosphate (TCP) and triphenylphosphate (TPP) used as plasticizers in plastics and lacquers. The International Contact Dermatitis Research Group (ICDRG) in 1976 examined the incidence of sensitization to TDB P and found two positives among 1103 patients. One of these two cases is reported here in detail. It concerns a woman, aged 56, with spectacle frame dermatitis. The spectacle frame did not contain TDB P and sensitization with another phosphate ester is assumed.
