What topical form contains more water than oil and is often used for itching?

The correct choice is cream. Creams are emulsions that typically contain a higher percentage of water compared to oil, which gives them a lighter texture and makes them easy to spread on the skin. This high water content contributes to their cooling and hydrating properties, making creams particularly effective for soothing itching and irritation. They are often used in dermatology for various skin conditions because they absorb quickly and are less greasy than ointments, which are oil-based and have a higher oil content.

In contrast, suspensions are mixtures of solid particles in a liquid, ointments are predominantly oil-based and provide a protective barrier, while elixirs are liquid preparations that contain alcohol and are mainly used for oral administration, typically not for topical itching. Each of these alternatives serves different purposes, but for the specific query regarding a topical form for itching that contains more water than oil, cream is the most suitable option.
