this study aims to investigate the capability of forming itraconazole containing niosomes with span 60 and brij 58 as non-ionic surfactants. lower cost and higher stability makes niosomes a more suitable choice in comparison with liposomes.the capability to form vesicles as an itraconazole delivery system and the influence of different factors such as type of surfactant and molar ratio of chole...
niosomes, non-ionic surfactant vesicles (nsvs), are the hydrated lipids composed mainly of different classes of non-ionic surfactants, introduced in the seventies as a cosmetic vehicle. nowadays, niosomes are used as important new drug delivery systems by many research groups and also they are effective immunoadjuvants which some commercial forms are available in the market. these vesicles rece...
A large number of non-ionic surfactants are discharged into water, which cause deterioration of water quality. Non-ionic surfactants have become an indicator of water quality monitoring. This article provides an overview of the classification of non-ionic surfactants, introduces the nature and hazards of fatty alcohol ethoxylates and alkyl phenol ethoxylates, and analyzes determination of non-i...
in this work, the interfacial interfacial polymerization (ip) technique was employed using terephthaloyl chloride (tpc) and p-phenylenediamine (ppd), as reactant monomers, to prepare poly(paraphenylene terephthalamide) thin film composite (tfc) nanofiltration on polyethersulphone (pes) support layer. the effects of six different anionic and non-ionic surfactants, in the aqueous phase on the mor...

the effect of different kinds of surfactants in various concentrations incorporated in an inert matrix, on the release of procainamide hydrochloride, as a cationic model compound, was investigated in this study. sodium lauryl sulfate and sodium stearate as anionic surfactants, cetyl pyridinium chloride and cetyltrimethyl ammonium bromide as cationic and span 60 and tween 80 as non-ionic surfact...
Due to the importance of super-hydrophobic silica aerogel powder as a material in the field of energy saving, its wettability in the presence of various surfactants was investigated. One anionic and two non-ionic surfactants with different molecular structures were used as wetting and dispersing agents. Wetting properties of the aerogel powders were investigated by the contact angle measure...

this paper presents the development of a model for evaluating adsorbable organic halogens’(aox) removal efficiency during wastewater treatment by using the micellar-enhanced ultrafiltration (meuf)technique. surfactants can form larger aggregates (micelles) were prepared into which aoxs dissolve and arethen retained by the membrane. synthetic wastewater samples containing certain concentrations ...
