Analytical Study Using HPLC on the Colorants Regulated by the European Standard EN71 for the Infant Textile Products (Toys and Clothes)

2010Volume 48 Pages 65-69

In the European Standard EN71 on the ‶Safety of Toys‶, 16 kinds of the coloring agents and 9 kinds of the aromatic primary amines for the dyes used in the toys made of textiles are regulated. By adding an artificial saliva, we conducted the dissolution test of the artificial sweat stipulated in ‶the color fastness test to a sweat of JIS (JIS L 0801:2004)‶ that was equivalent to the early test of EN71. According to the final test on 16 kinds of the coloring agents, it is stipulated that a qualitative test and a semi-quantitative determination method should first be performed by the photodiode array detection HPLC (HPLC-DAD). Therefore, we examined this analytical method, and then improved its method. By this improved method, we analyzed the 12 products (20 parts) of the textile products (toys and infant clothes) that were commercially available. As a result, it was found that there were no products matching to the reference products in both the spectrum and retention time, and that any of the regulated coloring agents was not used in the products analyzed.
