IMEP-35 : determination of total lead in lipsticks : interlaboratory comparison report

The Institute for Reference Materials and Measurements (IRMM) of the Joint Research Centre (JRC), a Directorate-General of the European Commission, operates the International Measurement Evaluation Programme (IMEP). It organises interlaboratory comparisons (ILC's) in support to EU policies. This report presents the results of a proficiency test exercise (PT) focussed on the determination of total lead in lipsticks which was organised in support of the European Council Directive 76/768/EEC (1976). Eighteen participants from thirteen countries registered to the exercise, of which 17 reported results. The percentage of satisfactory z-scores was 75 %. Therefore, the outcome of the exercise shows an overall good performance for European control laboratories assuring compliance towards the European legislation related to cosmetic products.
