**Controlled release**

The use of microencapsulation technology for a controlled release application is one of the best ways to increase efficiency and minimize environmental damage. It can achieve a controlled delay of the release of the active substance until a stimulus is encountered at a specific rate, time, or situation, i.e., heating, moisture, mechanical pressure, etc. In this case, the shell acts as a protective barrier to prevent diffusion and mass loss of the active substance, and therefore maintain intact the core compounds until final use.
