Cosmetics - Analytical methods - Measurement of traces of heavy metals in cosmetic finished products using ICP/MS technique (ISO 21392:2021)

This document provides a method for quantification of trace levels of heavy metals in cosmetic products.
This document refers only to chromium, cobalt, nickel, arsenic, cadmium, antimony and lead. The methodology can apply to other elements, however, it is the responsibility of the analyst to demonstrate that it fits that purpose.

Kosmetische Mittel - Untersuchungsverfahren - Messung von Spuren von Schwermetallen in fertigen kosmetischen Mitteln mittels ICP-MS (ISO 21392:2021)

In diesem Dokument wird ein Verfahren zur Quantifizierung von Spurenanteilen von Schwermetallen in kosmetischen Mitteln bereitgestellt.
Dieses Dokument bezieht sich nur auf Chrom, Cobalt, Nickel, Arsen, Cadmium, Antimon und Blei. Das Verfahren kann auf andere Elemente angewendet werden, es liegt jedoch in der Verantwortung des Analytikers nachzuweisen, dass es für diesen Zweck geeignet ist.

Cosmétiques - Méthodes d’analyse - Mesurage des éléments traces métalliques par ICP-MS dans les produits cosmétiques finis (ISO 21392:2021)

Le présent document fournit une méthode de quantification des teneurs en éléments traces métalliques dans les produits cosmétiques.
Le présent document ne traite que du chrome, du cobalt, du nickel, de l’arsenic, du cadmium, de l’antimoine et du plomb. La méthode peut s’appliquer à d’autres éléments, cependant, il incombe à l’analyste de démontrer qu’elle est adaptée aux fins recherchées.

Kozmetika - Analizne metode - Določevanje težkih kovin v sledovih v končnih kozmetičnih izdelkih z masno spektrometrijo z induktivno sklopljeno plazmo (ICP/MS) (ISO 21392:2021)

Ta dokument podaja metodo za količinsko opredelitev težkih kovin v sledovih v kozmetičnih izdelkih.
Navezuje se samo na krom, kobalt, nikelj, arzen, kadmij, antimon in svinec. Metodologijo je mogoče uporabiti tudi za druge elemente, vendar mora analitik dokazati,
da ustreza temu namenu.
