Sažetak
Immortelle acts as an antibacterial and anti- inflammatory agent for hematomas, scars, eczema, skin infections and allergic reactions healing. Due to those benefits, immortelle essential oil was used as an active ingredient in microcapsule synthesis, while ethyl-cellulose (EC) was chosen for the wall material. Two synthesis techniques were compared: A - stirring method and B - ultrasonic method, with the aim to optimize microencapsulation process. Three different methods were used for the characterization: Dynamic light scattering (DLS) for the microcapsules in dispersed particle form ; Confocal laser scanning microscope (CLSM) for synthesized microcapsules in dry state and Scanning electron microscopy (SEM) for the surface morphology of synthetized microcapsules applied to cellulose substrate (cosmetotextiles). DLS was also used to analyze zeta potential of synthetized microcapsules applied to cellulose substrate. All samples have shown the value of zeta potential within the range -37 and -47 mV, which indicates good stability of microcapsule suspension (i.e. repulsive forces prevail over attractive, thus preventing particles` aggregation) confirming good applicability for cosmetotextiles. Size of synthetized microcapsules proved to have influence on microcapsules effectiveness. In a case that active agent release rate needs to be increased the application of ultrasonic device is recommended for the synthesis, since it is resulting with smaller microcapsules of approx. 15 μm diameter which is considered as smaller size, easier for the application on textiles.
