L’analyse du spectre d’absorbance d’un produit ou ingr\u00e9dient cosm\u00e9tique, comme les filtres UV, joue un r\u00f4le crucial dans le domaine de la protection solaire. Elle permet d’examiner l’efficacit\u00e9 et le spectre de protection contre les UV (de 290 nm \u00e0 400 nm).<\/p>\n

Cette \u00e9valuation se r\u00e9alise en tra\u00e7ant la courbe d’absorption, soit en appliquant le produit sur un support appropri\u00e9, soit en le diluant directement dans une solution. La mesure est ensuite effectu\u00e9e \u00e0 l’aide d’une technique spectrophotom\u00e9trique.<\/p>\n
