"It is a type of emulsifying ointment, sometimes known as an emollient or moisturiser.
It is used to relieve the symptoms of dry skin conditions, such as cracked, scaly and itchy skin.
The emulsifying ointment leaves a thin layer of oil on the skin's surface that stops water evaporating.
This results in a soothing, softening and moisturising effect.
In general this drug is used to moisturise and soften dry skin."
