Cosmetics - Analysis of cosmetic products - Screening for UV-filters in cosmetic products and quantitative determination of 10 UV-filters by HPLC.

This European Standard specifies a multi-screening method using reversed-phase HPLC for the detection of UV-filters listed in the cosmetic regulations. The method is applicable for the quantitative determination of 10 UV-filters, which are mainly used in emulsion-based cosmetic products and sunscreen sprays particularly with regard to the maximum concentration listed in the cosmetic regulation.
Other analytical methods for the qualification and quantification of UV-filters may be used if they lead to comparable results.

Kosmetische Mittel - Untersuchung von kosmetischen Mitteln - Screening und quantitative Bestimmung von 10 UV-Filtern in Sonnenschutzmitteln, HPLC-Verfahren

Diese Europäische Norm legt ein Multi-Screening-Verfahren unter Anwendung der Umkehrphasen-HPLC zum Nachweis von in der Kosmetik Verordnung aufgelisteten UV-Filtern fest. Das Verfahren ist auf die quantitative Bestimmung von 10 UV-Filtern anwendbar, die vorwiegend in emulsionsbasierten kosmetischen Produkten und Sonnenschutzsprays eingesetzt werden, insbesondere in Bezug auf die in der Kosmetik Verordnung aufgelistete Höchstkonzentration.
Weitere Analysenverfahren zur qualitativen und quantitativen Bestimmung von UV-Filtern dürfen eingesetzt werden, sofern sie zu vergleichbaren Ergebnissen führen.

Cosmétiques - Analyse des produits cosmétiques - Détection des filtres UV dans les produits cosmétiques et détermination quantitative de 10 filtres UV par CLHP

La présente Norme européenne spécifie une méthode utilisant la chromatographie liquide haute performance (CLHP) en phase inverse pour détecter les filtres UV listés dans la réglementation sur les cosmétiques. La méthode est applicable à la détermination quantitative de 10 filtres UV qui sont principalement utilisés dans les produits cosmétiques à base d'émulsion et les sprays de protection solaire, tout particulièrement dans le respect de la concentration maximale indiquée dans la réglementation sur les cosmétiques.
D'autres méthodes analytiques pour la qualification et la quantification des filtres UV peuvent être utilisées si elles donnent des résultats comparables.

Kozmetika - Analiza kozmetičnih izdelkov - Detekcija UV-filtrov v kozmetičnih izdelkih in kvantitativno določevanje 10 UV-filtrov s tekočinsko kromatografijo visoke ločljivosti (HPLC)

Ta evropski standard določa metodo večkratne detekcije z reverzno fazno tekočinsko kromatografijo visoke ločljivosti (HPLC) za detekcijo UV-filtrov, navedenih v uredbah o kozmetičnih izdelkih. Metoda se uporablja za kvantitativno določevanje 10 UV-filtrov, ki se uporabljajo predvsem v emulzijskih kozmetičnih izdelkih in izdelkih za zaščito pred soncem v obliki razpršila, zlasti glede največje dovoljene koncentracije, ki je navedena v uredbi o kozmetičnih izdelkih. Druge analizne metode za kvalifikacijo in kvantifikacijo UV-filtrov se lahko uporabijo, če zagotavljajo primerljive rezultate.
