“…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].…”

“…So they were widely used as effective emulsifiers, bactericidal agents, dispersants, anti-foaming agents, detergents, etc. Recently these compounds were also applicable in the solubilization of dyes and pigments in the textile industry [10], gene therapy [11], the synthesis of highly mesoporous materials [12], etc. Nowadays, they are one of the most interesting objects of surface science.…”

Synthesis and aqueous solution properties of homologous gemini surfactants with different head groups

et al. 2007

A series of homologous gemini surfactants possessing identical hydrophobic chains but different ionic head groups (cationic, anionic, zwitterionic) were synthesized, and their aqueous solution properties were examined. The results showed that the surface activities of gemini surfactants are superior to those of corresponding conventional monomeric surfactants, and molecular arrangements of gemini surfactants at the air-water interface are tighter than those of corresponding conventional surfactants. It was also found that zwitterionic gemini surfactant possesses the highest surface activity among the three surfactants. The behavior at the air-water interface is closely related to the molecular structural features of surfactants, which provide an indication for synthesizing highly-efficient surfactants.

Two mono-Schiff base Mn(III) complexes were used to catalyze the hydrolysis of p-nitrophenyl picolinate (PNPP) in micellar solutions of n-lauroylsarcosine sodium (LSS) and polyoxyethylene(23) lauryl ether (Brij35). The results show that both catalysts enhance the hydrolysis of PNPP by over two orders of magnitude relative to the spontaneous rate at 25°C. Moreover, Mn(III)-promoted hydrolysis of PNPP was faster in LSS micellar solution than in both Brij35 micellar solution and pure buffer. Experimental sectionAll reagents, unless otherwise indicated, were of analytical grade and used without further purification. Ultrapure water used in the preparation of all the solutions was obtained from a Water Purification System (Nex Power 1000, Human Corporation, Korea) to achieve a resistivity of at least 16 MX cm -1 . The resulting pH of reaction solution was Electronic supplementary material The online version of this article (
