I & II C 1955 Jul;40(3):86-9. The aqueous phase hydrates the skin and the oily phase forms an occlusive covering which prevents loss of water by evaporation. Second, ointment bases have conveniently been grouped into classes that generally define their properties; knowledge about these class traits helps greatly in selecting an appropriate base for a particular use. They are non-water washable. Ointments thus prepared have been compared over a period of several months with the same ointments containing petrolatum. The most important role of an ointment base is to allow the release of the active ingredient.3 In a test studying the release properties of antibiotics, researchers compared the results of using hydrocarbon gel versus white petrolatum. :- anionic emulsifier, ceterimide Emulsifying ointment B.P.

Ointments thus prepared have been compared over a period of several months with the same ointments containing petrolatum. There are five (5) classes or types of ointment bases which are differentiated on the basis of their physical composition. Most oils mix easily with hydrocarbon bases, but they reduce the viscosity of the preparation. 4. Joseph Rodriguez (13) Aadrews, E..Aronsohn, H. G., Proc.

Various mixtures of fats, waxes, animal and plant oils and solid and liquid hydrocarbons; vehicles for medicinal substances intended for external application; there are four classes: hydrocarbon base, absorption base, water-removable base and water-soluble base; several are also emollients. • There are three official anhydrous Water miscible ointment base. E.. Klin. These are the earliest ointment bases which consisted of vegetable and animal fats as well as petroleum hydrocarbons. The conclusion reached as a result of this study is that Jelene is preferable to petrolatum because of its high stability over a wide temperature range.
