UV filtering acrylic sheet is used when UV light is not desired, and UV transmitting acrylic is used when UV light is required. C'est le même matériau de base mais diffère par le procédé de fabrication. We proposed therefore that these PMMA-encapsulated UV filters can be used as ingredients for sunscreen products in the future. Many classes of polymers are sensitive to moisture, meaning that when humidity changes, parts may suffer subtle shifts in dimension and other properties. Our results have demonstrated that PMMA-encapsulated UV filters have improved safety, photoprotective ability and photostability. The measurements were performed by C.
