La protection qu’apportent les produits cosm\u00e9tiques contenant des filtres solaires organiques ou inorganiques contre les coups de soleil n’est ni absolue ni permanente. L\u2019un des nombreux facteurs pouvant avoir un effet sur le niveau de protection conf\u00e9r\u00e9 par ces produits est le contact avec l\u2019eau. Les filtres UV contenus dans la formulation peuvent \u00eatre lessiv\u00e9s ou \u00eatre physiquement \u00e9limin\u00e9s par l’action de lavage dans la mer ou la piscine.<\/p>\n

Afin de rendre les produits solaires plus efficaces, les fabricants ont d\u00e9velopp\u00e9 des formulations plus respectueuses de la peau lors de l’immersion dans l’eau. Ces produits ont \u00e9t\u00e9 diversement \u00e9tiquet\u00e9s comme \u00e9tant r\u00e9sistants \u00e0 l\u2019eau ou tr\u00e8s r\u00e9sistants \u00e0 l\u2019eau.<\/p>\n

      La m\u00e9thode de comparaison statistique permet de comparer deux produits de protection solaire en termes de vieillissement, de lot, de benchmarck, etc. Sur la base de tout contr\u00f4le du spectre d\u2019absorbance entre une r\u00e9f\u00e9rence et un produit \u00e0 tester au moyen d\u2019une m\u00e9thode in vitro, deux r\u00e8gles importantes sont respect\u00e9es . Tout d\u2019abord, comparez en m\u00eame temps et dans les m\u00eames conditions les deux produits pour limiter la variabilit\u00e9 des mesures. Deuxi\u00e8mement, une v\u00e9rification en trois \u00e9tapes bas\u00e9e sur les valeurs d\u2019absorbance, y compris la comparaison de la forme des courbes, de la variabilit\u00e9 et de l\u2019intensit\u00e9.<\/p>\n

      Dans cette m\u00e9thode, une \u00e9tape sp\u00e9cifique pour comparer la r\u00e9sistance des deux produits peut \u00eatre ajout\u00e9e telle que la r\u00e9sistance \u00e0 l\u2019eau, la r\u00e9sistance au frottement, etc.<\/p>\n

            R\u00e9sistance \u00e0 <\/span>l'Eau<\/span><\/h1>\n\t\t\t\t<\/div>\n\t\t\t<\/div>La protection qu’apportent les produits cosm\u00e9tiques contenant des filtres solaires organiques ou inorganiques contre les coups de soleil n’est ni absolue ni permanente. L\u2019un des nombreux facteurs pouvant avoir un effet sur le niveau de protection conf\u00e9r\u00e9 par ces produits est le contact avec l\u2019eau. Les filtres UV contenus dans la formulation peuvent \u00eatre lessiv\u00e9s ou \u00eatre physiquement \u00e9limin\u00e9s par l’action de lavage dans la mer ou la piscine. Afin de rendre les produits solaires plus efficaces, les fabricants ont d\u00e9velopp\u00e9 des formulations plus respectueuses de la peau lors de l’immersion dans l’eau. Ces produits ont \u00e9t\u00e9 diversement \u00e9tiquet\u00e9s comme \u00e9tant r\u00e9sistants \u00e0 l\u2019eau ou tr\u00e8s r\u00e9sistants \u00e0 l\u2019eau. Afin de justifier ces all\u00e9gations d’efficacit\u00e9 du produit (r\u00e9sistance \u00e0 l’eau), diff\u00e9rentes m\u00e9thodes ont \u00e9t\u00e9 d\u00e9velopp\u00e9es et publi\u00e9es, tout en sachant qu’elles n\u00e9cessitent la mesure d’un facteur de protection solaire (FPS) avant et\/ou apr\u00e8s une proc\u00e9dure d’immersion dans l’eau.
