“…Gels are semisolid formulations which are generally made of two components, ,− usually a solid component (gelator) and a liquid component (ionic liquid, in case of ionogels). Rheological characterization is useful in understanding the properties of ionogels, for example their viscosity, viscoelasticity, gelation and melting temperatures, and their mechanical strength.…”

Ionic liquids (ILs) are liquid salts at ambient or lower temperatures and consist of ions and short-lived ion pairs. They are potential alternatives to toxic, hazardous, highly flammable, and volatile solvents for preparing solutions, dispersions, gels, composites, and polymeric melts. ILs have some very interesting and unique characteristics like good chemical and thermal stability and very low vapor pressures. They have good solvation interactions with a wide range of organic, inorganic, and polymeric compounds. They can enhance colloidal stability and the elasticity range of polymers. ILs are environmental friendly, easily recyclable, and structurally similar to the conventional solvents. For optimal performance, it is necessary to fully understand the rheological properties of ILs and their different systems for academic interests such as understanding the ability of ILs as processing aids particularly in film casting, fiber spinning and spraying, comprehension of thermodynamics and dynamics of polymer chains in ILs, analyzing the hydrodynamic volume of dispersed polymer, polymer–ILs interactions, characterizing the viscoelastic properties and nanophase–ILs interactions in nanocomposite systems, analyzing the plasticization efficiency, and the final properties of the composite system. The rheological analysis is also important for industrial purposes particularly for designing processing techniques and suitable operating conditions for IL based systems. The aim of this review is to give an overview of the rheological properties of pure ionic liquids and solutions, dispersions, gels, composites, and melts based on ionic liquids.

“…Oleogel is organogel phase usually made by self-assembly of either polymer or low molecular weight components to entrap the aqueous phase [14][15][16][17]. Accurately weighed quantity of organogelator such as fatty acids, fatty alcohol, lecithin, waxes, cyclodextrins steroids, and its derivatives, in predefined oil phase at a constant homogenization condition and temperature higher than melting point of the organogelator.…”

Bi-gels semi solid formulation is combination of organogel and hydrogel with better application property such as pharmaceutical and cosmetics. The main objective of this review is specially focuses on application of bi-gels as drug delivery vehicles by transdermal route. It contains two different phases which are polar and nonpolar due to which, it possess some significant features such as ability to deliver the hydrophilic and hydrophobic drugs which also have improved permeability of drugs, better spreading ability, and water wash ability. Hence, bigels have both organogels and hydrogels they can enhanced hydration of stratum corneum and also had an ability to manipulate the drug release rate from the dosage from.

“…Lupi et al investigated the microstructure and rheological properties of oleogels prepared with glyceryl stearate (MS), policosanol (P), and their mixtures. 12 The authors found that crystallization and gelation phenomena of compound oleogels seem to be mainly controlled by the P fraction, while dynamic moduli were influenced by both gelators. Thanks to the rheological and Fourier transform infrared spectroscopy (FTIR) measurements, they explained that, in the cooling process, P crystals formed the preliminary three-dimensional network of oleogels at high temperatures, whereas MS strengthened the network at low temperatures, which yielded a more consistent structure.…”

A combination of different gelators provides a pursuable way to create oleogels with enhanced properties. In this work, high oleic sunflower oil was structured using monoglycerides (MGs), waxes (carnauba wax, beeswax, candelilla wax, rice bran wax), and their mixtures, aiming at investigating the effects of compounding MG with wax on microstructures, the gelation process, and physicochemical and digestion properties of resultant oleogels. Compounding MG with wax leads to different oleogel properties of either only MG or only wax selected. During the gelation process, the onset of crystallization and gelation in compound systems is only controlled by the MG, while waxes are responsible for enhancing the basic network of MG crystals at low temperatures. The final elasticity of compound oleogels seems to be more affected by wax. Under optimal formulations, an oleogel with delayed digestion and stronger mechanical properties was obtained. The enhanced properties, mainly, arise from hydrogen bonding and a denser crystal network.
