Surface Chemical and Micellar Properties of Binary and Ternary Surfactant Mixtures (Cetyl Pyridinium Chloride, Tween-40, and Brij-56) in an Aqueous Medium

Diffusion Interactions of Some Biologically Important Transition Metal Complexes on Micellar Properties of Sodium Dodecyl Sulphate

“…Table 2 represents the micellization parameters. ΔG°m ic , free energy change of micellization, ΔH°m ic , enthalpy change of micellization and ΔS°m ic , entropy change of micellization calculated according to the equations and with the method of least squares (r 2 = 0.982) mentioned in the literature [24][25][26][27]. The free energy of micellization was calculated using the following equation :…”

Mixed Micellization and Interfacial Properties of Polyoxyethylene Sorbitan Esters with Cetylpyridinium Chloride: A Tensiometric Study

“…Sierra and Svensson [33] investigated the effect of chain length and the nature of the head group on the mixing behavior of pure alkyl glycosides with different surfactants. Although the micellar and interfacial characteristics of binary mixtures of cetylpyridinium chloride (CPC) with polyoxyethylene sorbitan monopalmitate (Polysorbate 40) [22] and polyoxyethylene sorbitan monostearate (Polysorbate 60) [34] have been studied separately, a systematic study of the effect of alkyl chain length of Polysorbates on the micellar and interfacial properties of binary mixtures with CPC is lacking.…”

“…Many theories have been proposed to explain the experimental results [9,[17][18][19][20][21][22][23][24][25]. Mixtures of surfactants of similar structures tend to behave ideally [26][27][28] whereas ionic-nonionic surfactant mixtures deviate from ideality [26][27][28][29].…”

Interaction between cationic and conventional nonionic surfactants in the mixed micelle and monolayer formed in aqueous medium

“…Then, nonideality of mixing has been taken into consideration by applying regular solution theory. Recently, several molecular thermodynamic theories have been developed for predicting the properties and interactions in binary surfactant systems [11][12][13] and analyzed in terms of different formalisms like that of Clint, Rubingh, Rosen, Motomura, Lange, and Clint, [14][15][16][17][18][19][20] to understand their behavior in aqueous solutions which based on phase separation model and assumes ideal mixing of the surfactants in the micellar phase. Rubingh proposed a treatment based on regular solution theory (RST) for nonideal mixed systems which have been extensively used.…”
