Abstract
An apparatus and method for preparing nanoemulsions from an oil phase and an aqueous phase, wherein the oil phase can be essential oils, such as damask rose essential oil. The apparatus includes a homogenization unit having a homogenization tank and a sonication unit comprising a sonication tank. The dispersion of oil phase and aqueous phase is passed between the homogenization unit and sonication unit multiple times to prepare the nanoemulsion.
Claims5
A method for preparing nanoemulsion from an oil phase and an aqueous phase, the method comprising:
- providing an apparatus comprising:
- a homogenization unit comprising a homogenization tank,
- a sonication unit comprising a sonication tank, wherein the homogenization tank and the sonication tank can be fluidly connected to one another so that liquid can circulate between the homogenization tank and the sonication tank, and
- a pump to affect the circulation of liquid;
- feeding a dispersion of the aqueous phase and oil phase into the homogenization unit, wherein the oil phase is an essential oil, and the aqueous phase is water, wherein the dispersion is prepared in a bioreactor, wherein the dispersion is subjected to degassing;
- adding an emulsifying agent to the homogenization tank at a predefined duration after adding the dispersion;
- continuous pumping, for a first predetermined duration, the dispersion from the homogenization unit to the sonication unit resulting in a circulation of the dispersion from the sonication unit to the homogenization unit.
