Gels pervade our daily life in a variety of forms such as agents in cosmetics and
pharmaceutical formulations, as well as cleaning products or food. A very wide range of materials have been recognised since the 1860's to form
gels, often with quite different characteristics. But, due to its variety and
complexity of the diverse systems it is not easy to write an absolute definition of
gel. Dorothy Jordon Lloyd wrote in 1926 that "the gel state is easier to recognise
than to define".
The reason lies in the fact that there is usually not a minimum of physical
parameters that allow one to write a clear-cut definition, however the designation
of a substance as a gel is only a visual observation (if no flow is observed, the
solution is said to have become a gel). Generally, gels are predominantly liquid in composition. Typically, 99% by weight
of the gel is a solvent while the remaining 1% is the gelator. And the solid-like
appearance of a gel is a result of the entrapment and adhesion of the solvent in
the large surface area solid 3D matrix formed by the gelator.
Gels can be classified in different ways depending on their source, medium,
constitution or type of interaction that creates their 3D network. [-]
