Mixed micelles of alkyltrimethylammonium bromides and chlorhexidine digluconate in aqueous solution

Interfacial and Micellization Behaviors of Binary and Ternary Mixtures of Amphiphiles (Tween-20, Brij-35, and Sodium Dodecyl Sulfate) in Aqueous Medium

“…With reference to the discussion related to Eq. [9], g (1 Ϫ f ). ⌬G m°i s the standard free energy change associated with micelle formation from the amphiphile monomers at their respective standard states of unit mole fraction.…”

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

“…In an aqueous medium, pure and a mixture of surfactants form micelles after a concentration, called the critical micellar concentration (CMC) whose determination has considerable practical importance normally to understand the self-organizing behaviors of surfactants in exact and detailed ways. Different binary mixtures formed by different surfactants such as nonionic/nonionic (1,(7)(8)(9)(10)(11), anionic/nonionic (12)(13)(14)(15)(16)(17)(18), cationic/nonionic (18)(19)(20)(21)(22), anionic/biosurfactant (23,24), cationic/anionic (25,26), cationic/cationic (27)(28)(29), and anionic/ anionic (30)(31)(32) have been studied in recent years and relevant theories of Clint (33), Motomura (34), Rubingh (35), and Blankschtein (36)(37)(38) have been proposed and used to analyze and compare those experimental results to reveal the synergistic and antagonistic behaviors of the binary combinations. A molecular thermodynamic theory in this direction that explicitly includes contributions reflecting the hydrophilic head and hydrophobic tail structures of the surfactants has also been developed (36)(37)(38)(39)(40)(41)(42)…”

Mixed Surfactant Systems

“…At higher surfactant concentrations with boloform mole fractions greater than 0.5, mixed micelle formation is promoted and negative deviations from ideality are observed. Mixtures of the di-cationic surfactant chlorhexidine digluconate with ordinary cationic surfactants have also been studied (77), as well as mixtures of different cationic bolaform and anionic surfactants including bolaforms with trimethylammonium bromide (78) and pyridinium head groups (79,80). Mixed micellar systems with bolaform surfactants are reviewed in this volume by Zana (87).…”
