抄録

  From May 2015, leather products come in contact with human skin may not be placed on the EU market by REACH regulation if they are shown to contain over 3 ppm of Hexavalent Chromium (Cr VI). For watch strap, a large amount of chromium is contained because of chromium tanning. Even if only Trivalent Chromium is contained when manufacturing the straps, it was already proved that Hexavalent Chromium is generated subsequently by oxidation. Therefore, Hexavalent Chromium (Cr VI) Elimination Agent was developed. This agent restores Hexavalent Chromium to Trivalent Chromium and prevent oxidation of Trivalent Chromium.
