Abstract:
Microencapsulation is recognized as an effective method to protect different types of active agents. Oil-containing microcapsules were prepared by interfacial polymerization using isocyanates as an oil-soluble monomer and amines as a water soluble monomer. The core content was essential oil mixed with a vegetable oil and a fragrance. Then, the protective barrier was a polyurea polymeric shell. Microcapsules were obtained with and without fragrance, and some reactives were modificated to do the encapsulation. In this project was prepared since 3μm to 40μm capsules, changing the procedure conditions.
