“…Recently, new surfactants and surfactant additives have been proposed, i.e., linker-based surfactant systems [23][24][25][26] and extended surfactant systems. These systems have been introduced to improve the solubilization of organic solutes [25,[27][28][29]31].…”

Adsolubilization reaches its maximum when a surfactant adsorbed onto the solid-liquid interface achieves complete bilayer or maximum adsorption. The attempt to enhance the adsolubilization of organic solute is accomplished by increasing interaction between the hydrophobic core of adsorbed admicelles and the organic solute. Solubilization and adsolubilization were studied with linkerbased and extended-surfactant-based systems. Extended surfactants have propylene oxide (PO) groups of intermediate polarity inserted between hydrophobic and lipophilic moieties in the surfactant molecule. This study evaluated the adsolubilization of polar (phenylethanol) and nonpolar (ethylcyclohexane) solutes into conventional linker-based and extended-surfactant-based admicelles. The results demonstrated that the extended-surfactant-based systems showed higher solubilization capacity than the conventional sodium dodecyl sulfate alone or with linker. For the polar solute, the presence of PO group has a greater effect than the number of PO groups or the tail length, while for the nonpolar solute as the number of POs groups and the tail length increased, the adsolubilization capacity also increased. Preliminary explanations for these observations are provided.

“…One particular case of oil mixture solubilization is when long chain alcohols, often called lipophilic linkers, are added to the microemulsion in order to boost the solubilization of a hydrophobic oil [3][4][5][6][7]. These lipophilic linkers must also be considered as oils because they are not miscible with water, and remain primarily on the oil side of the microemulsion.…”

“…Previous modeling of the lipophilic linker effect [2][3][4][5][6][7][8][9] concentrated on the optimum formulation only, predicting the solubilization enhancement at the optimum, the optimum salinity for anionic surfactant systems, and the optimum EON for non-ionic surfactant systems as a function of the linker concentration. The optimum formulation is the middle phase microemulsion solubilizing equal volumes of oil and water.…”

“…For the "simple" benzene-limonene oil mixtures linear mixing rules for the optimum salinity and characteristic length were appropriate [2]. However, for the dodecanol-limonene mixture strong departure from linearity was observed due to the much stronger surface excess adsorption of dodecanol compared to benzene [5]. Hence, more accurate mixing rules had to be developed [5].…”

Hence, more accurate mixing rules had to be developed [5]. In these mixing rules the optimum salinity and the characteristic length are related to the polar oil surface excess rather than the oil composition.…”

Solubilization selectivity and synergism behavior were investigated for the optimum Winsor type III sodium dodecyl sulfate (SDS) microemulsion systems of organic mixtures. The organic mixtures used include toluene and 1 of the following 3 normal alkanes: n‐octane, n‐heptane, and n‐hexane. Selective solubilization toward toluene was observed in the optimum Winsor type III SDS microemulsion system for the toluene/n‐octane mixture. Toluene selectivity showed a decrease trend with the increase of its content in the excess oil phase, salinity showed little influence on the trend, and increasing of the SDS content leads to lowering of the selectivity. Synergism exists in the solubilization of the 2 organics for all the binary mixtures used in this work. A clear reduction of the n‐butanol content (A*) to obtain the optimum formulation and rise of the optimum solubilization parameter (SP*) were seen with the mixing of 2 single components. Coincident relation between A* and equivalent alkane carbon number (EACN) for organic mixtures of toluene with the 1 or 3 of n‐hexane, n‐hexane, and n‐octane was obtained, which is a parabolic curve with a minimum point. At the same time, all the SP*–EACN data fall in the same kind of parabolic curve with a maximum. The EACN for the minimum A* and maximum SP* are both in the range of 3.0–3.5. The A*–EACN curve shifts vertically with the change of the SDS content or ln S* (S* is salinity of the aqueous phase), while the change of salinity also leads to slight deformation of the curve, which can be omitted in a small range of salinity change.
