Abstract
A new method for the preparation of microencapsulated essential oils is disclosed. The microcapsules containing essential oils or a formulation containing thereof may be used for various non-agricultural applications.
Claims18
A microcapsule having an outer encapsulating amphiphatic shell surrounding a core, said outer encapsulating amphiphatic shell consisting essentially of a multivalent salt form of at least one alkanoic acid, and said core comprising at least one essential oil.
A microcapsule having a core comprising at least one essential oil, said microcapsule being prepared according to a method comprising:
- (I) obtaining a microencapsulated essential oil formulation, the formulation being in the form of a suspension of microcapsules in an aqueous medium;
- wherein said formulation is obtained by a 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 microcapsules having an outer encapsulating amphiphatic shell, said outer amphiphatic shell consisting essentially of a multivalent salt form of the at least one alkanoic acid;
- (II) isolating and collecting said microcapsules from said aqueous media, and
- (III) optionally adding an absorbent capable of absorbing any unencapsulated oil present therein, thereby obtaining microcapsules comprising at least one essential oil.
