Abstract
Mikroemulzije su optički izotropni i termodinamički stabilni sustavi vode, ulja i surfaktanata, često u kombinaciji s kosurfantantom koji je potreban za optimalno stvaranje mikroemulzije s manjim radijusom agregata i s većom zakrivljenošću međupovršinskog sloja. Potpuni potencijal mikroemulzijskih sustava tek treba biti realiziran te se očekuje puno inovacija u području mikroemulzijske tehnologije. Imaju brojne prednosti zbog spontanog formiranja, jednostavnosti izrade i proširenja, termodinamičke stabilnosti, mogućnosti poboljšanja solubilizacije lijeka i biodostupnosti. Ovaj rad se bavi mikroemulzijskim sustavima koje sadrže neionske surfaktante Tween 80 i Span 80, izopropil miristat kao uljnu fazu te ultračistu vodu. Iz najpogodnijeg mikroemuzijskog područja su odabrani uzorci koji su analizirani, prazni i sa inkapsuliranom askorbinskom kiselinom, mjerenjem raspodjele veličine mikroemulzijskih agregata, indeksa loma, električne provodnosti i napetosti površine.
Abstract (english)
Microemulsions are optically isotropic and thermodynamically stable systems of water, oil and surfactant, often in combination with a cosurfactant which is required for optimal formation of microemulsion with a smaller aggregate radius and greater curvature of the interfacial layer. The full potential of microemulsion systems has yet to be realized and a lot of innovation in the field of microemulsion technology is expected. They have numerous advantages due to spontaneous formation, ease of manufacturing and scale-up, thermodynamic stability, ability to improve drug solubilization, and bioavailability. This work describes microemulsion systems which contain nonionic surfactants Tween 80 and Span 80, isopropyl myristate as the oil phase and purified water. From the most suitable microemulsion region, samples were selected and analyzed, empty and with encapsulated ascorbic acid, by measuring the size distribution of microemulsion aggregates, refractive index, electrical conductivity, and surface tension.
