Цель работы – исследование влияния параметров синтеза на средний гидродинамический радиус мицелл витамина E (альфа-токоферол ацетат). Проводили многофакторный эксперимент, включающий три входных параметра и уровня варьирования. В качестве выбраны: температура (t), концентрация (С (Е)) ПАВ (Tween 80 или Kolliphor HS 15) С (ПАВ). выходного рассматривали (Rср). рамках исследования E, стабилизирова...

the available minoxidil formulations for topical application suffer with major drawback having less contact time with the scalp which requires repeated application. hence, the present study was aimed to investigate the effect of microemulsions and microemulsion based hydrogel systems (mehs) for increased percutaneous penetration of minoxidil. minoxidil microemulsions were developed by following...

The morphology and corrosion behavior of electrochemically prepared Ag nanostructures (NSs) have been examined in the absence and presence of potassium citrate, polyvinylpyrrolidone (PVP) and polyoxyethylene(20) sorbitan monolaurate (Tween-20). These additives give rise to morphologically distinct Ag NSs. The presence of citrate increases the dissolution of Ag and creates finer nanostructured A...

Abstract The optimum processing conditions for PEDOT:PSS and PEDOT:PSS/Tween 80 cast films were investigated by considering film quality resistivity. thermal stabilities of these materials found to strongly influence the accessible annealing temperatures, especially in presence conductivity-enhancing agent Tween 80. resistivities with without decreased up 85% increases both temperature time unt...

Oil-in-water nanoemulsions were prepared by emulsification and solvent evaporation using whey protein isolate (WPI), lactoferrin and Tween 20 as emulsifiers. Protein-stabilised nanoemulsions showed a decrease in particle size with increasing protein concentration from 0.25% to 1% (w/w) level with Z-average diameter between 70 and 90 nm. However, larger droplets were produced by Tween 20 (120-45...
