Surfactants are adaptable amphiphilic compounds have an especially distinctive polar hydrophilic head and non-polar tail group. The surfactant is extensively used in each walk of life such as care products, domestic cleaners, pharmaceuticals, oil recovery, food handling, nanotechnologies due to decreasing the interfacial tension,. Micellization anionic surfactants potassium dodecyl sulphate (KD...

Supramolecular property systems composed of alkyltrimethylammonium surfactants and β-cyclodextrin were studied by means of a chemical probe. Solvolysis of 4-methoxybenzenesulfonyl chloride (MBSC) was used in the mixed systems with the aim of being able to determine the concentration of uncomplexed cyclodextrin in equilibrium with the micellar system. The surfactants used enabled us to vary the ...

Amphiphiles are molecules, which have covalently bonded hydrophilic (soluble in water) and hydrophobic (insoluble in water) groups. In aqueous solution such molecules self-assemble into aggregates of various shapes and sizes. Many amphiphiles (e.g., surfactants, block copolymers) form spherical aggregates called micelles above a certain amphiphile concentration, known as the critical micelle co...

We have studied the micellization of surfactants SDS, CTAB and tweens-80 using a series of Ethylene glycol/water and formamide/water mixed solvents using surface tension, viscosity and conductance measurements. The results are compared with those reported in pure water for the same surfactants. The critical micelle concentration (cmc) shifts to lower values upon increasing the ratio of Ethylene...
