ENCAPSULATED ESSENTIAL OILS |
摘要 |
The invention provides a process for the preparation of essential oil microcapsules comprising dissolving a di- or polyisocyanate into an essential oil, emulsifying the resulting mixture in an aqueous solution containing a di- or polyamine, and or a di or polyhydroxy compound to effect encapsulation of said essential oil through interfacial polymerization, whereby there is formed a polyurea and/orpolyurethane film around the essential oil droplets which film enhances the stability of said essential oil, reduces its evaporation rate and controls its release rate when applied to a substrate. |
