| Sumario: | Physicochemical parameters, epsilon, lambda, solubility in water and Brij-35, pKª, Ka and photostability for dihydroeuparin, 5-acetyl-2, 3-dihydro-6-hydroxi-2-isopropenyl-benzo (b) furan (from Senecio Graveolens), were obtained and compared to those of o-hidroxyacetophenone. Its sunscreen capabilities, SPF and SSPF, were obtained for both compounds and compared to those of homomenthylsalicylate (homosalate). Results indicate that dihydroeuparin has sunscreen behavior at 270-340 nm zone, with high photostability, high solubility in miscellar system, apparently is a non-toxic substance and shows higher sunscreen capabilities than homosalate |
