Abstract
A capsule () for use in a smoking article includes a liquid sensory enhancing material; and a shell surrounding the liquid sensory enhancing material. The shell has an outer surface rendered hydrophobic by hydrophobic groups covalently bond to the outer surface of the shell. The shell may be rendered hydrophobic by reacting hydroxyl groups at outer surface of the shell with fatty acid halides to covalently attach fatty acid moieties to the surface of the capsule.
