Scope

This standard specifies the methods for the determination of hexavalent chromium in
cosmetics, by diphenylcarbazide spectrophotometry and ion chromatography-
inductively coupled plasma mass spectrometry.
This standard applies to the determination of hexavalent chromium in cosmetics. When
the sample weight is 2 g, the detection limit of diphenylcarbazide spectrophotometry is
0.25 mg/kg, the quantification limit is 0.83 mg/kg; the detection limit of ion
chromatography-inductively coupled plasma mass spectrometry is 0.010 mg/kg, the
quantification limit is 0.033 mg/kg.

Summary	This standard specifies the method for the determination of hexavalent chromium in cosmetics by diphenylcarbazide spectrophotometry and ion chromatography-inductively coupled plasma mass spectrometry. This standard applies to the determination of hexavalent chromium content in cosmetics. When the sample weight is 2g, the detection limit of diphenylcarbazide spectrophotometry is 0.25mg/kg, the limit of quantification is 0.83mg/kg; the detection limit of ion chromatography-inductively coupled plasma mass spectrometry is 0.010mg /kg, the limit of quantification is 0.033 mg / kg.
