| الوصف: | The main goal of this thesis was to determine the methodology best suited for the quantification of active substances on cosmetic textiles, before and after their release in washing cycles. Prior to development of methodology for quantifying active substances on cosmetotextiles, it was necessary to synthesise microcapsules. Active substances, α-tocopherol and immortelle essential oil were selected and three different types of microcapsules were synthesised (containing α-tocopherol, immortelle essential oil and mixture of α-tocopherol and immortelle essential oil). The synthesis was optimised and the best amount of active substance and ethyl cellulose, which plays the role of a membrane in the synthesised microcapsules, in rate 1:3, (oil: ethyl cellulose) was selected for further investigations. Both, α-tocopherol and immortelle essential oil are very sensitive to external influences and encapsulation was a logical choice to prevent their decomposition, i.e. premature evaporation during and after the application to textiles. The synthesised microcapsules were analysed gravimetrically and microscopically to determine their morphology and to detect the presence of oil in the microcapsules. Antioxidant analysis was performed and demonstrated using Electron Spin Resonance (ESR) technique. As expected, α-tocopherol showed very strong antioxidant activity, but immortelle essential oil as an active substance showed significant antioxidant potential as well. Microcapsules containing α-tocopherol and the ones containing immortelle essential oil were selected for application to textiles. Cotton fabric was selected as a potential cosmetotextile due to its natural origin, hydrophilic and pleasant characteristics in contact with the skin. Studies were also conducted on other textile materials (e.g. PES/cotton, silk, modal and liocel). Three different applications methods were carried out: impregnation, exhaustion and electrospinning. Exhaustion method has proven to be the most acceptable, as it allowed a uniform binding of ... |
