Microencapsulation is carried out to change the apparent state and properties of the core material, protect the material in a finely-divided form, control, release, and release the contents at the time desired. In recent years, application of microcapsules to image recording materials, medicines, perfumes, agricultural chemicals, chemicals, adhesives, foods, detergents, dyes, solvents, catalysts, enzymes, rust inhibitors, etc., has been studied, and pressure-sensitive copying paper, aspirin capsules, perfume capsules, pressure-sensitive capsule adhesives, active charcoal capsules, enzyme capsules, liquid crystal capsules and methylparathion capsules, etc. have been put to practical use. As generally known processes for producing microcapsules, etc. have been put to particle use. there are physical processes, mechanical processes, physiochemical processes and chemical processes. In this study, we encapsulated halgenated hydrocarbon oil by the use of melamine-formaldehyde by in-situ polymerization, and surfactants were poly(styrene sulfonic acid), sodium lauryl sulfate. Particle size and morphology are observed by scanning electron microscope.
