DESCRIPTION

21/30387777 DC


This standard 21/30387777 DC BS EN ISO 23674. Cosmetics. Analytical methods. Direct determination of traces of mercury in cosmetics by thermal decomposition. Atomic absorption spectrometry (mercury analyzer) is classified in these ICS categories:
  • 71.100.70 Cosmetics. Toiletries

The aim of this document is to provide a procedure of quantification of mercury traces in cosmetic products that consumers might be exposed to in their usage. This method describes the determination of mercury traces in cosmetics by direct solid analysis with no need of external digestion. Total mercury (both inorganic and organic species) can be quantified either in solid or liquid samples.

This standard has been developed in parallel with another method of determination of traces of mercury in cosmetics: ISO 23821 Cosmetics – Analytical methods – Determination of traces of mercury in cosmetics by atomic absorption spectrometry (AAS) cold vapour technology after pressure digestion [1]. Knowing this, an interlaboratory test using either one or the other method was performed on same tailor-made cosmetic products in order to establish that both methods fulfilled the same requirements (see Annex B).
