Molecular aggregation of cationic surfactants and aromatic compounds

Aggregation of an anionic azo dye with conventional cationic surfactants in premicellar region: A conductometric study

The interaction of Congo Red CR with a series of Alkyltrimethylamoniumbromide CnTAB, N-hexadecylpyridinium bromide CPB and N-hexadecylpyridinium CPC were investigated using conductometry technique. It was observed that the formation of dye-surfactant ion pairs takes place at surfactant concentration far below the critical micelle concentration of the individual surfactants. Aggregation was refl...

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Interactions of β-lactoglobulin with Cationic Surfactants: Spectroscopy Study

The interactions of β-lactoglobulin AB in the presence of cationic surfactants such as Cetyltrimethylammonium bromide and Cetyltrimethylammonium p-Toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, UV-Vis spectrophotometry and fluorimetry. The conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...

Interactions between Cationic Starch and Anionic Surfactants

Interaction of arginine-based cationic surfactants with lipid membranes. An experimental and molecular simulation study

The effect of two arginine-based cationic surfactants, arginine N-lauroyl amide dihydrochloride and arginine O-lauroyl ester dihydrochloride, upon dipalmitoylphosphatidylcholine liposomes, is addressed in this work. Some aspects concerning the synthesis of these surfactants are also presented in some detail. Differential scanning calorimetry, as well as fluorescence anisotropy using several pro...
