The physicochemical properties and contact angle of sodium dodecyl sulfate in water–acetone with and without sodium nitrate (NaNO3)

Study on the association and phase separation behavior of surfactants and promethazine hydrochloride: impact of ammonium electrolytes

“…The aggregate formation of surfactants has been reported to rely on the presence of additives and experimental conditions. 50–52 The hydrophilic and hydrophobic characteristics of the surfactant moiety, the presence of an aqueous additive solution, and environmental factors, such as temperature, affect the CMC value. When the energy produced by the association of the hydrophobic portion of the monomer is adequate to overcome electrostatic repulsion among ionic head groups, the entropy loss that accompanies the aggregation, micellization occurs.…”

“…The micelle development concentration (CMC) is determined from the break point acquired in the κ vs. [surfactant] plots. 49–52…”

Influence of twin-headed gemini micellar system on the study of methionine amino acid with ninhydrin in buffer solution

“…Generally, surfactant molecules can be characterized into four categories: nonionic, anionic, cationic and amphipathic. Their nature depends on the charge of the hydrophilic head group [1][2][3][4][5][6][7][8]. Because of the dual nature of a surfactant system, they differ from other surface-active materials.…”

Association behavior and physico-chemical parameters of a cetylpyridinium bromide and levofloxacin hemihydrate mixture in aqueous and additive media

“…The level of surfactants at which this micellization phenomenon occurs is referred to as the 'critical micelle concentration' (CMC). [18][19][20][21][22][23][24][25] The structure of surfactant molecules is similar to those of biological membranes. When drugs undergo interaction with surfactant molecules, one may nd it amazing to envisage how the mode of interaction takes place with that of biological membranes.…”
