Two types of gel
Single-phase gel
Two-phase gel
Gels in which macromolecules are distinguished somewhat uniformly in a liquid vehicle & no apparent boundary can be seen
Single-phase gel
Gels made up of flocculated small
distinct particles

Second classification scheme of gels
Hydrogels
Organogels
dispersible as colloidal or soluble in water; they include organic hydrogels, natural & synthetic gums, & inorganic hydrogels.
Hydrogels
Include the hydrocarbons, animal & vegetable fats, soap base, greases, & the hydrophilic organogels.
Organogels
