Particles suitable for inclusion in a dry product or article, typically
a laundry powder, comprise a core of swellable material, e.g. an organic polymer,
containing perfume absorbed therein, the core being coated with water-soluble encapsulating
material impervious to the perfume. The coating of the particles acts to prevent
premature evaporation or dissipation from the particles of the loaded perfume until
the coating is dissolved on contact with water in use.
