%X A reversed-phase high performance liquid chromatographic method was used to detect 5 dyes including p-phenylenediamine in cosmetrics. A Zorbax C8 column was used and mobile phase was V (triethanolamine):V(water):V(acetonitrile) = 0.95:94.05:5 adjusted to pH 7.7 by phosphoric acid. The wavelength 280 nm was selected. Samples were extracted with 95% ethanol by ultrasonic method. The recoveries were 87%-107% and the relative standard deviations were 2.3%-6.4%.
