20.500.12556/DKUM-26726 Evaluation of thermosensitive microspheres as potential components for sun-protectors Ocena termowrażliwych mikrosfer jako potencjalnych składników preparatów chroniących przed światłem słonecznym In this study thermosensitive polymeric microspheres obtained in former research were evaluated in vitro for their photoprotective activity. The UVA/UVB ratio was assessed at so called shelf temperature i.e. at 25°C, and at elevated temperature of 45°C. The evaluated polymers absorb higher levels of UV radiation, when heated from 25°C to 45°C. The MS1 polymer may be defined as polymer with high efficiency in the terms of gaining protection against UVAradiation, when heated. The MS2 absorbs both UVA and UVB radiation, and maybe considered, as most protective, when heated to 45°C. The equalized and less strong activity has the polymer MS3 when heated, with lipophilic radical implemented during synthesis. thermosensitive polymers photoprotection UV radiation N-isopropylacrylamide true true false Angleški jezik Angleški jezik Neznano 2012-05-31 14:49:11 2012-05-31 14:49:11 2022-04-15 03:42:25 2024-01-03 03:35:03 2010 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677.017:543 14722582 0370-0747 URN:SI:UM:DK:ZAUMALD8 http://www.polimery.am.wroc.pl/pdf/114.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=35835 Fakulteta za strojništvo 0 0 0
