Layered double hydroxides intercalated with dodecylsulfate or dodecylbenzenesulfonate were synthesized
by co-precipitation under alkaline conditions. After characterization by PXRD, FTIR, and TGA/
DTA, the ZnxAl/SUR compounds were reacted with neutral benzophenone, using different procedures.
The products obtained from benzophenone adsolubilization were investigated by PXRD, FTIR, and
DRUV–Vis spectroscopy before and after exposure to UV radiation. In general, the content of adsolubilized
benzophenone was small and depended on the synthetic procedure. The best results were achieved
under microwave irradiation, which furnished 9.09 wt% adsolubilized benzophenone. The products presented
good adsorption in the full UV region, from UVC to UVA, and good stability to UV radiation. They
did not cause skin irritation in tests conducted on rabbits, which makes them good candidates for the
development of a new generation of sunscreens.
