“…Previously, we have reported [27,28] such a type of theoretical applicability on gemini surfactants (212 and GA) with conventional nonionic ethoxylated surfactants (C 12 E 8 and C 12 E 5 ). Such a discussion on comparative analysis of theories of mixed micellar systems with various combinations (taken from literature) will review the scope and validity of the different theoretical models.…”

Mixed micelles are an ever-interesting field in applied as well as academic research. An interesting problem is to determine the composition of the mixed monolayer and the micellar phase and interaction parameters among the individual components. Several theories have already been put forward to address these problems. In this work, we attempt to apply several theories to several experimental systems already published. Experimental elucidation of the proportion of individual components in such a mixed state of aggregation is impossible up till now to the best of our knowledge.

“…A large number of experimental studies [1,2,8,14,[17][18][19][20][21][22] have focused on the mixed micellization behavior of ionic gemini surfactants and nonionic conventional surfactants in aqueous solutions and the importance of synergism could be understood in these mixed systems.…”

“…Properties of mixed surfactant systems have been studied by various techniques [44][45][46][47]. Mixed micelles of oxyethylene based nonionic surfactants with cationic [48][49][50], anionic [51], dimeric anionic [52,53] and dimeric cationic surfactants [54,55] have been studied. In this Brought to you by | Penn State -The Pennsylvania State University Authenticated Download Date | 5/27/15 7:31 AM paper we have taken six cationic geminis of the series alkanediyl -, -bis(dimethylalkylammonium bromide), (alkyl: tetradecyl, hexadecyl and alkane: butane, pentane and hexane), and studied tensiometrically their micellization with nonionic surfactant Cremophor EL.…”

Surfactant solutions in practical applications usually are mixtures of different types, especially ionic and nonionic ones. The mixing behavior of nonionic Cremophor EL-cationic gemini systems was therefore investigated by surface tension measurements. The Gemini surfactants used were of the type alkanediyl -, -bis(dimethylalkylammonium bromide), (alkyl: 14 or 16 and alkane: butane, pentane or hexane), designated in the text as 14-s-14/16-s-16 (where s is the spacer length). The experimental results indicated that the mixed systems of EL with 16-6-16, 14-5-14 and 14-6-14 have lower cmc values than of pure surfactants. Comparison between experimental and calculated values of cmc (cmc and cmc id ) showed that the interaction between the component amphiphiles inside aggregates of EL with RH, 16-4-16, 16-5-16 and 14-4-14 was not ideal but shows antagonism. Such fact was reflected by the values of activity coefficients also. This may be due to the steric repulsions which decrease with the increase in spacer length. The aggregates were mainly comprised of geminis at low stoichiometric mole fraction of EL ( 1 ) while by EL at high 1 . The molecular interaction parameter, m , calculated using Rubingh's approach, was negative for mixed systems of EL with 16-6-16, 14-5-14 and 14-6-14. Surface parameters, evaluated by Rosen's model, also suggested mixed monolayer formation with negative for all 16-s-16, 14-4-14 and 14-6-14 systems.
