Mineral sunscreens (also known as physical sunscreen or sunblock) contain mineral ingredients — usually zinc oxide or titanium dioxide. These sit on top of the skin, creating a physical barrier that blocks and scatters UV radiation before it penetrates the skin. Chemical sunscreens, on the other...
Physical UV-blocker TiO2 nanocomposites and chemical sunscreen benzophenones (BPs) have been frequently detected in the aquatic environment, their combined fates and potential risk should be concerned. In this study, the typical cosmetic grade UV-blocker TiO2 nanocomposites (labeled as CG-TiO2) and ...

Physical sunblock is often referred to as natural or mineral sunscreen. It sits on top of the skin versus getting rubbed in, so it’s less likely to clog pores. Physical sunscreen remains visible, but does come in a variety of tones, much like your foundation. ...
As a first application, the 3D-FFD device was applied to produce sodium alginate The same device (3D-FFD) was used for nanoprecipitation of Benzophenone-3 (BZ-3), a typical sunscreen agent used in cosmetic products [37,44,45]. As mentioned previously, nanoprecipitation processes occur after ...
