Urea-Formaldehyde Microcapsules for Insects Repellent purposes

Microcapsules are the material of choice for several applications that include pharmaceutical products, insulation technology, food preservation, personal care products and many more. Urea-formaldehyde polymers can be converted to microcapsules by oil-water emulsion method. Microcapsules were characterized by optical microscope, FTIR and SEM. Microcapsules can encapsulate the dyes and mosquito repellant, which can be released slowly under different conditions. The release studies indicate that the microcapsules can be used as a slow release of mosquito repellant, especially for the domestic purposes.
