“…Comprehensive experimental systematic studies of the solubilization of long-chain hydrophobic components by gemini surfactant micelles are, unfortunately, still missing and experimental evidence of the role of spacer group length is, to our knowledge, not yet available. [43][44][45][46][47] …”

The solubilization of hydrophobic components by surfactants that form microemulsion droplets has been investigated from a theoretical point of view. By means of combining thermodynamics of self-assembly to form small systems with bending elasticity theory, we have been able to demonstrate a strong correlation between the second critical micelle concentration (CMC 2 ) of surfactant micelles and their solubilization capacity (σ). The correlation may be rationalized as a consequence of all three bending elasticity constants spontaneous curvature (H 0 ), bending rigidity (k c ) and saddle-splay constant (k c ) showing similar trends with respect to the two quantities, i.e. σ increases and CMC 2 decreases with decreasing values of k c H 0 and increasing values of k c and k c , respectively. As a result, we demonstrate that the solubilization capacity is predicted to always be higher for a gemini surfactant with CMC 2 = 11 mM as compared with a gemini surfactant with CMC 2 = 18 mM. The predicted correlation between solubilization capacity and CMC 2 agrees with experimental observations showing that surfactants forming larger micelles in general have better solubilization capacity than surfactants forming smaller micelles. The theory also demonstrates, in agreement with experiments, that σ is raised in the entire range of surfactant concentrations, below as well as above CMC 2 , regardless of micelle size. Consequently, our theory predicts that small micelles formed below CMC 2 increase in size, whereas large rodlike or wormlike micelles formed above CMC 2 decrease in size, as a hydrophobic solubilizate is added to a micellar solution. © 2018 Author(s)

“…cmc of gemini surfactants being 10 to 100-times smaller than that of conventional single-chain surfactants, results in much less skin irritation which allows to use them as skin permeation enhancers [18]. A smaller value of their cmc also enables them to be efficient solubilisers of low soluble drugs [19], dyes [20,21], hydrocarbons such as n-hexane and toluene [22]. Gemini surfactants can also serve as structural units in the formulation of cationic liposomes [23].…”

“…These properties make gemini surfactants of special interest for biological and biomedical applications. Gemini surfactants appear to be adequate drug carriers due to their much lower CMC values and higher solubilization capacities compared with those of the corresponding monomeric surfactants [7][8][9][10]. These characteristics suggest that gemini surfactants with a degradable or stimuli-sensitive spacer can form micelles for controlled drug release.…”
