Microemulsion-based-organogels

Abstract

A novel gel (Microemulsion-based-organogel, MEBG) prepared by the addition of gelatin to W/O microemulsion, was first reported by Luisi et al. and Eicke et al. in 1986. The conditions and mechanism for MEBG formation and MEBG structures have extensively been investigated by methods. MEBGs are a transparent and thermally reversible and in which, water phase and oil phase domain were present together. Therefore, MEBGs are materials which enable us to solubilize mutually many more reactive molecules. Consequently, MEBGs are very interesting materials for the chemical and pharmaceutical applications, and also applied studies have been started. In this review, first, studies of the conditions and mechanism for MEBG formation and MEBG structures, next, physico-chemical properties for MEBGs, furthermore, examples for applied studies for MEBG and fundamental study toward application, were described.
