Notes:
A 73-year-old patient, diagnosed as having seborrheic dermatitis, was patch tested with his hair preparations. The hair stick gave a positive reaction. Among its ingredients, D & C Yellow No. 11, from 0.0001% to 0.1%, and perfume showed positive reactions. D & C Yellow No. 11 was found to consist only of quinophthalone by chemical analyses. The concentration of quinophthalone in the hair stick was determined as 9.41 ppm w/w by high-performance liquid chromatography.
