ABSTRACT

Atualmente, são utilizadas técnicas in vitro e in vivo para a avaliação do Fator de Proteção Solar (FPS) e do Fator de Proteção de UVA (FPA). O presente trabalho propõe a revisão das técnicas para as avaliações desses fatores in vitro preconizadas por FDA (Food and Drug Administration Agency) e COLIPA (European Cosmetic, Toiletry and Perfumery Association). O enfoque maior foi direcionado à análise espectrofotométrica de soluções diluídas e à espectrofotometria de reflectância com esfera integrada.


Currently, both in vitro and in vivo techniques are used to measure Sun Protection Factor (SPF) and UVA Protection Factor (APF). This paper reviews the in vitro techniques to test these factors, recommended by the FDA (USA Food and Drug Administration) and COLIPA (European Cosmetic, Toiletry and Perfumery Association). The main focus is on the spectrophotometric analysis of dilute solutions and the use of reflectance spectrophotometry with an integrating sphere.
