There are good reasons why ointments are oil based rather than water based. A water based ointment would wash away too easily. An oil based ointment stays put. A water based ointment could be washed away by sweat, where oil would remain.

What is the difference between ointment and cream?

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


What are the general classification of ointments and their sub-classification?

Ointments can be classified into various categories based on their composition and purpose. Some common classifications include oil-based ointments, water-based ointments, and emulsion-based ointments. Sub-classifications can further categorize ointments based on specific ingredients, such as corticosteroids, antibiotics, antifungals, or antipruritics. Each sub-classification serves a different therapeutic purpose.


How do pastes differ from ointments and creams?

Ointments are petroleum based - thus the slightly greasy feeling. Creams are water based. As for which is appropriate for usage - I go by this rule. Creams tend to dry out the area on which they are used (which are great for things like acne, etc). Ointments will hydrate the skin more - so if the skin is dry to begin with (not oily), then ointment is your best bet. You should be able to get both the ointment and cream in the same strength (% solution). Hope this helps.
