Abstract
Method for the preparation of microencapsulated essential oils or a formulation thereof for various non-agricultural applications.
Claims18
A method for the preparation of a microencapsulated essential oil formulation, said method comprising:
- (a) admixing at least one alkanoic acid with a water-immiscible liquid, wherein said water-immiscible liquid comprises at least one essential oil, thereby obtaining a water-immiscible mixture;
- (b) admixing the water-immiscible mixture of step (a) with an aqueous basic solution to obtain a suspension;
- and
- (c) admixing into the suspension of step (b) an aqueous salt solution comprising at least one multivalent cation, thereby obtaining a microencapsulated essential oil formulation, being in the form of a suspension of microcapsules in an aqueous medium, each having a core containing at least one essential oil and an outer amphiphatic shell surrounding the core.

A method for the preparation of a microencapsulated essential oil formulation, said method comprising:
- (a) admixing at least one alkanoic acid and at least one essential oil with at least one absorbent thereby obtaining a solid mixture;
- (b) optionally admixing at least one additive with said absorbent and said solid mixture;
- and
- (c) exposing the solid mixture of any of steps (a) or (b) to an aqueous solution comprising at least one multivalent cation, thereby obtaining a microencapsulated essential oil formulation, being in a solid form whereas said formulation comprises a dispersion of microcapsules in a nonvolatile solid vehicle, such that each microcapsule comprises at least one essential oil.
