Organogels are non-crystalline, non-glassy thermoreversible solid materials composed of a liquid organic phase entrapped in a structuring network. The liquid can be e.g. an organic solvent, a mineral oil or a vegetable oil. The solubility and particle dimensions of the structurant are important characteristics for the elastic properties and firmness of the organogel. Often, these systems are based on self-assembly of the structurant molecules.
Additional recommended knowledge
Organogels have raised interest for use in a number of applications, such as in pharmaceutics , cosmetics, art conservation, and food. An example of formation of an undesired thermoreversible network is the occurrence of wax crystallisation in crude oil .
