Resumen
In this work, the photochemical behavior of β-cyclodextrin (βCD) encapsulated Parsol® 1789 sunscreen under ultraviolet radiation UVA (320- 400 nm) is reported using chemometrics. The photochemical study on the free and βCD included molecule in some solvents was carried out under UVA light and probing by fluorescence and absorption spectroscopies. The chemometric method developed by Lawton and Sylvestre was employed in order to resolve the spectra and the concentration profiles. The results showed that βCD complexation did not increase the Parsol® photochemical stability, regardless of the employed solvents. However, it may reduce the effects related to photoallergy/phototoxicity through inclusion of the photoproducts. 480-481
