ice giant

(planet more massive than gas planets and less than rocky planets)

An ice giant is a planet consisting mostly of elements heavier than hydrogen and helium such as oxygen, carbon, nitrogen, and sulfur. Uranus and Neptune are examples.

The term ice is used in an astronomy/planetary-science sense, specifically, a volatile material (gaseous at some or all "everyday" temperatures) with a freezing point above 100K.
