22-12-2005

37 Kohl products and 25 henna products were collected. An analysis of basic elements in selected products was carried out. All henna products were analysed for para(p)-phenylendiamin and Lawson, where p-phenylenadiamin is used in oxidatively based hair dyeing products and Lawson is a natural constituent of henna. Lead was found in the majority of kohl products as impurities, the highest concentration was 0,028%. Lead was found in 10 of the 17 henna products analysed in concentrations between 0,5 mg/kg and 2,0 mg/kg. P-phenylendiamin was found in three products and in one product the concentration was 17% (the limit stated in Statutory Order on Cosmetic products is 6%). Lawson was found in 14 out of 25 products analysed with the highest concentration being 0,34%.
