Abstract
In this paper, the synthesis and identification of UV blocking ointments using titanium dioxide/zinc oxide/medicinal plant extracts composite has been studied. These ointments are used to protect the skin against harmful ultraviolet rays that may damage the skin. In this research, five main materials including titanium dioxide, zinc oxide, vitamin E, Aloevera, and sodium lauryl sulfate were used as surfactants and homogenizers. Titanium dioxide nanoparticles were synthesized by ultrasonically assisted sol-gel method, while zinc oxide was synthesized by hydrothermal method at 24 hours. Vitamin E was extracted and used from pharmacy capsules, and Aloevera plant extract was obtained. The results of various analyzes including XRD, SEM, FT-IR, and EDX showed that the studied compounds were successfully synthesized and identified. Titanium dioxide nanometer particles were produced by forming a regular and homogeneous shape. The UV-VIS results also showed that the ointments have peaks associated with light absorption in a certain range, which points to the potential of using them in UV barrier products. Also, FT-IR and EDX spectra provided accurate confirmation of the chemical composition of the samples. This research facilitates improving our understanding of the properties of titanium dioxide and zinc nanoparticles and their applications in the UV barrier industry.
