Cosmetics - Analysis of cosmetic products - Quantitative determination of zinc pyrithione, piroctone olamine and climbazole in surfactant containing cosmetic anti-dandruff products

This European Standard specifies an analytical method for the detection and quantitative determination of the following anti-dandruff agents: zinc pyrithione, piroctone olamine and climbazole in surfactant-containing cosmetic products in the concentration range from 0,1 g/100 g to 1,0 g/100 g. NOTE The method is also suitable for the determination of ketoconazole and ciclopirox olamine (q.v. Annex A) in surfactant-containing cosmetic products and it is probably applicable for the determination of the substances in non surfactant-containing cosmetic products. For these purposes, the method has not been validated.

Kosmetische Mittel - Untersuchung von kosmetischen Mitteln - Quantitative Bestimmung von Zinkpyrithion, Pirocton-Olamin und Climbazol in tensidhaltigen kosmetischen Mitteln mit Antischuppenwirkstoffen

Dieser Normentwurf beschreibt ein Analysenverfahren für die Detektion und die quantitative Bestimmung der folgenden Antischuppenwirkstoffe: Zinkpyrithion, Pirocton-Olamin und Climbazol, in tensidhaltigen kosme-tischen Mitteln im Konzentrationsbereich von 0,1 g/100 g bis 1,0 g/100 g.
ANMERKUNG Das Verfahren ist auch für die Bestimmung von Ketoconazol und Ciclopiroxolamin (siehe Anhang A) in tensidhaltigen kosmetischen Mitteln geeignet und es ist wahrscheinlich anwendbar bei der Bestimmung dieser Substanzen in nicht-tensidhaltigen kosmetischen Mitteln. Für diese Zwecke wurde das Verfahren jedoch nicht validiert.

Cosmétiques - Analyse des produits cosmétiques - Détermination quantitative de la pyrithione de zinc, de la piroctone olamine et du climbazole dans les produits cosmétiques antipelliculaires contenant des agents de surface

La présente Norme européenne spécifie une méthode d'analyse pour la détection et la détermination quantitative des agents antipelliculaires suivants : la pyrithione de zinc, la piroctone olamine et le climbazole présents dans des produits cosmétiques contenant des agents de surface, dans une gamme de concentration comprise entre 0,1 g/100 g et 1,0 g/100 g.
NOTE La méthode convient également pour la détermination du ketoconazole et de la ciclopirox olamine (voir l'Annexe A) présents dans des produits cosmétiques contenant des agents de surface et elle est probablement applicable pour la détermination de ces substances dans des produits cosmétiques qui ne contiennent pas d'agent de surface. Toutefois, la méthode n'a pas été validée pour ces applications.

Kozmetika - Analiza kozmetičnih izdelkov - Kvantitativno določevanje cinkovega piritiona, pirokton olamina in klimbazola v kozmetičnih izdelkih proti prhljaju, ki vsebujejo površinsko aktivne snovi

Ta evropski standard podrobno določa analitično metodo za ugotavljanje in kvantitativno določevanje snovi proti prhljaju, kot so cinkov piriton, pirokton olamin in klimbazol v kozmetičnih izdelkih, ki vsebujejo površinsko aktivne snovi v koncentracijah od 0,1 g/100 g do 1,0 g/100 g. OPOMBA Metoda je ustrezna tudi za določanje ketokonazola in ciklopiroks olamina (glej dodatek A) v kozmetičnih izdelkih, ki vsebujejo površinsko aktivne snovi in je verjetno uporabna tudi za določevanje snovi v kozmetičnih izdelkih, ki ne vsebujejo površinsko aktivnih snovi. Metoda za ta namen ni bila potrjena.
