Development and optimization of ointment preparation for burn healing
Müllerová, Kristýna ; Sedláček, Petr (referee) ; Enev, Vojtěch (advisor)
This bachelor's thesis aims to prepare ointments based on an ointment base with the addition of a bioactive component of chlorophyll according to a recipe from an unknow doctor. The basic characteristic of emulsions was performer in the theoretical part, their instability and possible methods of stabilization were described. Furthermore, the reader is acquainted with the bioactive substance of chlorophyll, selected ointments for the healing of burns and wounds and finally with the use in medicine. In the Experimental part, the preparation of emulsion bases of ointment was described. Based on a performed analysis of stability using analytical centrifuge, two ointments bases were selected, to which other components were added – chlorophyll, beeswax, and chamomile extract. The stability of completely prepared ointments was studied at 25 °C and 37 °C, this analysis was performed even after a longer time interval. Using ATR-FTIR spectrometry the present functional groups were identified at prepared ointments, individual components of the ointments base and chlorophyll. Based on the stability measurement of the prepared ointments and rheological measurements (oscillation and rotational measurements), it was evaluated that the best properties were shown by the prepared ointment with an ointment base consisting of 30 wt. % white vaseline and 70 wt. % synderman.
