A Surfactant-Water-Oil System with Weakly Charged Films

Effect of Alkyl Sulfate on the Phase Behavior of Microemulsions Stabilized with Monoacylglycerols

“…Moreover, the addition of ionic surfactants can reduce the sensitivity of the microemulsions stabilized by ethoxylated nonionic surfactants to temperature changes [36], and it has a great influence on the phase behavior [34][35][36][37][38]. SDS is a common very hydrophilic anionic surfactant often appearing in microand macroemulsion formulation, and those structures have been extensively studied by various methods [39][40][41][42].…”

Effect of temperature and salt on the phase behavior of nonionic and mixed nonionic–ionic microemulsions with fish-tail diagrams

“…Fig. 6B depicts the phase behavior of the mixed system Brij-56/SDBS/1-butanol/n-heptane/water at different temperatures (20,30,40, and 50 • C) at α = 0.5 (fixed) with δ = 0.1. It has been observed that no three-phase body is formed at the studied temperature range.…”

“…Blending of nonionic surfactants with ionic surfactant can also improve their solubilization capacity [15][16][17][18]. Addition of ionic surfactant reduced the temperature sensitivity of nonionic surfactant [19] and also influenced the phase behavior [20][21][22]. Mixing of surfactants can often be proved to be advantageous over use of a single surfactant, since they can extract properties superior than the individual ones.…”

Phase behavior, interfacial composition and thermodynamic properties of mixed surfactant (CTAB and Brij-58) derived w/o microemulsions with 1-butanol and 1-pentanol as cosurfactants and n-heptane and n-decane as oils

“…Microemulsion systems formed with mixed surfactants are known to offer properties superior than the pure components [35][36][37]. It is known that ionic and nonionic surfactants physicochemically behave in opposite manner with change in temperature [38].…”
