This work comprises a study of the adsorption–desorption of three chemical sunscreens on the polymer surface of the latex Aquacoat, which has a high specific surface. The aim was to delay the release of these filters from the silicone excipient containing them and therefore increasing the substantivity, i.e. prolonging the sunscreening effect.
