UV Screening of Ferulic Acid–Zinc Basic Salt Nanohybrid with Controlled Release Rate
Abstract:Ferulic acid (FA), an organic UV absorber and free radical scavenger, was intercalated into an inorganic zinc basic salt (ZBS) matrix to prepare a UV screening material. FA molecules were vertically oriented bilayer in the ZBS lattice with an expansion of ∼22.7 Å along the c-axis. The FA–ZBS nanohybrid exhibited a superior UV-A∼UV-B screening ability and an antioxidant activity that was comparable to that of a pure FA molecule. The in vitro release test showed the biphasic release of the FA molecules from the FA–ZBS nanohybrid that consisted of an initial burst, followed by a slow and sustained release.
