Comment:
- Other names: Simple ointment.
Hydrous emulsifying ointment.
Unguntum emulsifi aquosum (UAE).
- Use: Anionic base; emollient.
- This type of creams is incompatible with cationic drugs.
- Cationic drugs could be incorporated in cetomacrogol cream or
aqueous cetrimide cream.
- Chlorocresol is ncorporated in the formula as a preservative; its disadvantage
is the phenolic odor which is not prefered by some users. In this case it could
be replaced by compound hydroxy benzoate soultion; 1 ml for each 100 ml of
the cream.
