Information @ a Glance

  • A Gemini surfactant (GS) consists of two conventional surfactant molecules chemically bonded together by a spacer.

  • Properties includes unique structure, covalently linked, better wetting property.

  • GS have been used in the synthesis of new mesoporous zeolites for catalysis.

  • The most important feature of Gemini surfactants are lower CMC, higher surface activity (more efficiency in reducing the water surface tension) and special micelle structures.

  • A promising surfactants in industrial detergency and have shown efficiency in skincare, antibacterial property, metal-encapped porphyrazine and vesicle formation,construction of high porosity materials.

  • When compared to conventional surfactants, Geminis are three orders more surface active.

  • The higher surface activity of this surfactant is useful for many applications in the industry for detergency and emulsification.

  • New class of Gemini surfactant has been emerged which composed of two hydrophobic tails and cationic head groups linked together by spacer group that is cationic Gemini surfactants.

  • Applications of cationic surfactants includes softeners, electro dicoatings, cosmetic products.

  • It have remarkably low critical micellization concentrations (CMC) when compared with corresponding surfactants of equivalent chain length.

  • Models of this surfactants includes 1.Phenomenological model 2.Computer Simulations 3.Phase Behaviour.

  • The project carried out by interactions between Gemini surfactants and a series of surfactants which is commonly found in pharmaceutical formulations.

  • Considered as a effective potential transfection agents for non-viral gene therapy.

  • The unique properties of these surfactants along with the increasing demand for high performance is currently driven into more potential applications.
