Title
Evaluation of skin sensitization potential of nickel, chromium, titanium and zirconium salts using guinea-pigs and mice
Abstract

Contact sensitization capacity of four metal salts, nickel sulphate (NiSO4), potassium dichromate (K2Cr2O7), titanium chloride (TiCl4) and zirconium chloride (ZrCl4), was evaluated using guinea-pigs and mice. In the guinea-pig sensitization tests, we set up an injection concentration to 1% for all chemicals, and changed the challenge concentration. Guinea-pigs were sensitized with NiSO4, K2Cr2O7 and TiCl4. Among the test metal salts, K2Cr2O7 showed the highest sensitization rate and strongest skin reactions. ZrCl4 did not cause any sensitization responses under our experimental conditions. Minimum challenge concentration to cause a skin response was <0.25% for K2Cr2O7, 0.5% for NiSO4 and 2% for TiCl4, respectively. A sensitive mouse lymph node assay (SLNA) also determined NiSO4 and K2Cr2O7 as a sensitizer. In the SLNA, TiCl4 caused mild lymph node responses, but was classified as a non-sensitizer as well as ZrCl4. Considering these results, the order of sensitization potential was K2Cr2O7 > NiSO4 > TiCl4 > ZrCl4. NiSO4- and K2Cr2O7-sensitized animals did not show any reactions to ZrCl4 and TiCl4. No cross-reaction among these metal salts was found.
