The relative strength of interaction between anionic (SDS) and nonionic surfactant (octaethoxylated oleyl alcohol, GEN) and homologous series of peptides was determined by reversed-phase thin-layer chromatography (RP-TLC) carried out on alumina layers impregnated with paraffin oil. The relative strength of interaction was calculated and was correlated with the physicochemical parameters of pept...

The structure and interaction parameters of micelles in solutions of anionic surfactant sodium oleate (SO) in deuterated water were studied by small-angle neutron scattering. The effect of addition of polymer, polyethylene glycol (PEG), on micelle solutions was investigated. The dependences of the micelle aggregation number, degree of ionization, axial ratio, average size, charge, inverse scree...

Calcium oxide (CaO) nanoparticles are known to exhibit unique property due to their high adsorption capacity and good catalytic activity. In this work the CaO nanocatalysts were prepared by hydrothermal method using anionic surfactant, sodium dodecyl sulphate (SDS), as a templating agent. The as-synthesized nanocatalysts were further used as substrate for the synthesis of alumina doped calcium ...

Paul Ehrlich, in 1909, initiated the development for targeted delivery when he envisaged a drug delivery mechanism that would target directly to diseased cell. Drug targeting can be defined as the ability to direct a therapeutic agent specifically to desired site of action with little or no interaction with non target tissue 1 . In noisome, the vesicles forming amphiphile is a non-ionic surfact...

Behaviors of nonionic-anionic surfactant sodium fatty Alcohol polyoxyethylene Ether Carboxylate (AEC) at dodecane/water interface influenced by inorganic salts NaCl, CaCl2 and MgCl2 were investigated by interfacial tension methods and molecular dynamics simulation. Contrasted distributions of various salts at interface and in aqueous solutions and resulting lowering the interfacial tension have...

In this report, results from the project, proposed in the original research plan are presented. 10 surfactant systems effective as drag reducing agents (DRA’s) in efficient district cooling, including four commercial cationic surfactants, one commercial and three novel synthesized zwitterionic surfactants, one commercial nonionic surfactant and one zwitterionic(synthesized)/anionic surfactant m...

Host defense roles for the lung collectins, surfactant protein A (SP-A) and surfactant protein D (SP-D), were first suspected in the 1980s when molecular characterization revealed their sequence homology to the acute phase reactant of serum, mannose-binding lectin. Surfactant protein A and SP-D have since been shown to play diverse and important roles in innate immunity and pulmonary homeostasi...

The objective of this study was to investigate the influence of surfactant charge, surfactant carbon chain length, and surfactant content on the physicochemical characteristics (ie, vesicle size, zeta potential, elasticity, and entrapment efficiency), morphology, stability, and in vitro skin permeability of meloxicam (MX)-loaded liposome. Moreover, the mechanism for the liposome-enhanced skin p...

The objective of this paper is to measure the deposition of solid impurity on finished cotton fabric with DMDHEU resin treated during washing cycles of cotton fabric treated with different softeners. Fabrics will be softened with the conventional esterquat and with aminosilicone products having different molecular weights and mixtures of both. The anionic surfactant sodium dodecil benzenesulpho...

In this article, the effect of sodium dodecyl sulfate (SDS) as an anionic surfactant on the thermodynamics, formation rate, formation kinetic, critical micellar concentration (CMC) and stability of methane hydrate was studied. A CMC of SDS and water solution for methane hydrate formation conditions in a batch process was measured at 450 ppm, where CMC was determined by hydrate induction time. I...
