Abstract:
In this study, a [0001]-plane planar-type ZnO ceramic powder material with a high aspect ratio ranging from 20:1–50:1 is synthesized using the electrolyte collected from zinc air battery power generation. This high aspect ratio may be due to the Zn(OH) 2- 4 anion dissolved in the electrolyte. The obtained planar-type ZnO exhibits excellent formulation stability and applicability, even when formulated as a cosmetic with a single inorganic ingredient. Compared to commercial ZnO or TiO 2 powders, relatively better protection against infrared
and ultraviolet (UV) radiation is realized due to its asymmetric characteristics, with a width of approximately 1 μm and thickness of tens of nm. The synthesized planar-type ZnO is mixed with nanosized ZnO or TiO 2 commercial powders and formulated into various combinations to
achieve a high UV protection rate and heat-blocking effect. In particular, the addition of planar-type ZnO to nanosized TiO 2 powders increases the heat-blocking effect, and improves the applicability and formulation stability of the cosmetic formulation, despite the decrease in
turbidity. Among all the ceramic powder combinations examined in this study, the best UV protection rate and heat-blocking effect are obtained when the synthesized planar-type ZnO is mixed with microsized and nanosized TiO 2 .
