Hygroscopic

Drawing and holding water from the air — the property that lets honey spoil if left open.

Chemistry

Definition

Honey attracts atmospheric moisture. A jar left open in a humid kitchen gains water at the surface, and that layer can ferment while the rest is unaffected. The same property is why honey cakes stay moist for far longer than sugar cakes, and why honey is used as a humectant in cosmetics.
