Water-removable bases like O/W are also known as?

Explanation:
Water-removable bases are emulsions where oil droplets are dispersed in water (oil-in-water), so the continuous phase is water. Because they’re water-washable, they are described as hydrophilic ointments. This type of base is less greasy than purely oil-based bases and can incorporate water-soluble drugs more readily, making it easy to wash off with water. The other options refer to oil-based, petrolatum-rich bases (oleaginous) or brand names representing those oil-based formulations, which do not fit the water-washable category.
