Preparation of skin masks with the anti-acne effect
Geierová, Kateřina ; Bendová, Agáta (referee) ; Márová, Ivana (advisor)
This bachelor thesis was focused on the preparation and characterization of nanofibers containing active agents with the aim of using these materials in anti-acne facial masks. The nanofibers were prepared from polyhydroxybutyrate solution and gelatin solution by electrospinning method. Among the active ingredients, eugenol and piperine were used to functionalize the nanofibers. In the theoretical part, the types of face masks, the individual active ingredients, the materials for the preparation of nanofibers, their preparation methods and their characterization were characterized. In the practical part, the antioxidant and antimicrobial activity of the active ingredients themselves was investigated. Subsequently, the release rate of selected active ingredients from the prepared nanofibers was monitored in three model environments. The antimicrobial activity of the nanofibers was monitored on three microorganisms, namely Staphylococcus epidermidis, Cutibacterium acnes and Escherichia coli.
