A microcapsule has an inner core & an outer shell. The core can be either liquid (oil or water) or solid and typically contains the active ingredient while the shell is usually a polymer or wax.
A microsphere is a solid matrix particle & the active ingredient in the matrix is usually dissolved or melted in it before processing.
