Microemulsion Formation and Phase Behavior of Anionic and Cationic Surfactants with Sodium Dodecyl Sulfate and Cetyltrimethylammonium Bromide

Synthesis and characterization of ultrafine CeF3 nanoparticles modified by catanionic surfactant via a reverse micelles route

“…[32] represented, but the difference is that the oppositely charged surfactant heads play an important role in minimizing repulsions between the same charged surfactant heads and decreasing the interface tension [33]. These results are in accord with the reference [34] that the mixed surfactants are more effective than a single surfactant in forming microemulsions with low surfactant content. Due to the higher surface activity of a catanionic surfactant, water is more easily dispersed and forms smaller reverse micelles in organic phase.…”

Critical Micelle Concentration and HLB of the Sodium Oleate–Hexadecyltrimethylammonium Bromide Mixed System

“…It was stated in the literature that the mixing ratio of cationic to anionic surfactants affects the solubilization of microemulsions and phase behavior [39][40][41][42][43].…”

Formation of Cubic-Phase Microemulsions with Anionic and Cationic Surfactants at Equal Amounts of Oil and Water

“…The ultra-low surface tension and maximum solubilization of microemulsions for equal amounts of water (or brine) and oil can also be obtained by mixing of an anionic and a cationic surfactant and alcohol (26)(27)(28)(29). Various liquid crystals, including the cubic phase, appear in the above systems at low hexanol content and were not investigated in detail in the previous paper (29).…”
