Simply put, microencapsulation is a process by which tiny particles of liquid, or solid active ingredient or even a gas, can be surrounded by a second material for the purpose of shielding the material or active ingredient from the surrounding environment. These particles, or capsules, which range in size from one micron (one-thousandth of a millimeter or one millionth of a meter) to seven millimeters, release their contents at a later time depending on the ultimate need or the application. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane. Modification of particles to mask flavors, reactivity, solubility, odor, color, and wetting characteristics is one of the most important yet least understood particle processes. Which method is best for the application? If you are looking for improved waterproofing characteristics out of your pigments or wish to eliminate color bleeding, how does one go about achieving this?
