Oleaginous ointment bases are non-water-soluble, greasy substances used in topical formulations. They are primarily composed of oils and fats, which provide a thick, occlusive layer on the skin, promoting moisture retention and enhancing drug absorption. Common examples include petrolatum, mineral oil, and various waxes. These bases are ideal for delivering lipophilic (fat-soluble) drugs and are often used for their emollient properties.
Ointments that are soluble in water are those that contain oleaginous bases. This component in ointments are also called hydrocarbon bases. It has an emollient effect and protects against the escape of moisture.
There are a few ways to prepare the bases. When preparing the bases that includes both oleaginous and aqueous components, use fusion.
The method of preparing bases to be used when the base includes both oleaginous and aqueous components is the "one-pot" method. In this method, all components are combined into a single vessel at the same time and heated together until fully blended. This approach ensures proper emulsification and stability of the base.

Classified according to the ointment bases 1. Oleaginous bases ointments eg: hydrocarbon bases like soft & hard paraffin, ceresine, animal & vegitable oil bases 2. Absorption bases eg: beeswax, woolfat 3. Water soluable bases eg: macrogols 4. Emulsifying bases eg: emulsifying wax
Creams are an O/W (oil in water) emulsion. Creams contain a small amount of oil dispersed in water. Most creams are "vanishing." They do not show once applied and are more cosmetically acceptable to most patients. Ointments are an W/O (water in oil) emulsion. Ointments are considered semisolid. Examples of bases used in ointments are: OLEAGINOUS or greasy based made from hydrocarbons such as in mineral oil or petroleum jelly. Other examples of W/O emulsions are lanolin or cold cream
