The study of UV protection materials (original) (raw)

2018

Abstract

Most people are aware of how harmful UV radiation is to the skin. The sun’s ultraviolet rays, UVA and UVB, are known to cause skin damage, from freckling and moles to fatal skin cancer. That’s why it is important to apply sunscreen products to your skin, to help you stay sun safe and absorber harmful ultraviolet rays. This research is studied to focus on how to make UV materials to protect UV radiation. The UV absorber additive materials are 4 types; nanoZnO solid powder at size 25-50 nm (ZnO-1), nanoZnO 40%wt in ethanol solution (ZnO-2), nano TiO2 solid powder at size 17-50 nm (TiO2-1) and nano TiO2 solid powder 325 mesh (TiO2-2) respectively, that was mixed in pure baby lotion cream. Three concentration of UV absorber additive materials are 5, 10 and 15 % by weight were compared with pure baby lotion cream. All compositions were tested UV absorbance with UV spectroscopy together with studied micro structure of UV absorber additive materials by Field emission scanning electron micr...
