Abstract: [slo] [eng]
Táto diplomová práca bola zameraná na vývoj organických UV filtrov. Organické UV filtre boli extrahované z prírodných látok a enkapsulované do nanomateriálových nosičov ako sú lipozómy a nanovlákna. Boli stanovované SPF jednotlivých extraktov a pripravených nosičov s extrahovanými látkami. Jednotlivé extrakty aj nosiče boli charakterizované na obsah prírodných látok. Stanovovaná bola aj ich stabilita a cytotoxicita, mikrobiálna aktivita a nezávadnosť. Pripravené materiály sa preukázali ako vhodné nosiče v kozmetickom priemysle. Štúdiu by však bolo vhodné doplňiť ďalšími experimentálnymi metódami pre navýšenie účinných látok a zároveň zvýšenia SPF ochranného faktoru. This diploma thesis is focused on the development of organic UV filters. Organic UV filters were extracted from natural resources and encapsulated into nanomaterial-like delivery systems such as liposomes and nanofibres. SPF of particular extracts and carriers with encapsulated extracts were measured. All of the prepared extracts as well as carriers were characterised for their content of natural substances like phenolic compounds and their antioxidant acitvity, stability, cytotoxicity, micriobial acitivity and their safety were studied too. All of the prepared materials were evaluated as suitable for use in comestic industry. However, in a future, it would be appropriate to add to the study other experimental methods to increase the active substances and at the same time increase the SPF protection factor.
