Cooling Agent WS-5 is the latest in a long line of cooling agents. Each have their own different ways of cooling different areas of the mouth and tongue and to different degrees.
WS-5 is one of the strongest of all the cooling agents and is derived from menthol, although it is virtually odourless and has no taste. It provides a smooth and well rounded cooling effect and primarily affects the roof of the mouth and the back of the tongue.
