- Abstract
To investigate the content of elements in children's cosmetics, a method for the determination of 40 elements in children's cosmetics by super microwave digestion inductively coupled plasma mass spectrometry was established. After validation of the methodology, 75 batches of samples were determined and the results were analyzed. Results show that the methods meet the requirements of cosmetic testing with simple, rapid, accurate and can be used to the determination of elements in children's cosmetics. The determination results of mercury, lead, arsenic and cadmium all conform to the standard. In the determination of nickel, chromium and barium, two batches of barium are 0.88 and 0.62 mg/kg, one batch of nickel is 6.71 mg/kg, and other samples are all less than 0.5 mg/kg. The determination results of titanium element range from 0.2 to 82.5 mg/kg. One batch of silver determination result is 6.83 mg/kg. The 16 rare earth elements are less than 0.1 mg/kg, and the other elements are less than 0.3 mg/kg. It is suggested that in children's cosmetics, the limits of nickel, chromium, barium and their salts should be studied, the health risk of titanium content should be evaluated, and the detection method of silver potassium cyanide should be improved. Rare earth elements and other elements are in good safety condition with low safety risk.
