Study on garlic oil pre-emulsion and therefore dispersion

In order to improve dispersion performance and stability of garlic oil,an anhydrous,brown color,clear and sticky liquid,named as pre- emulsion was prepared by mixing with ethanol and Tween 80 orderly.The better pre- emulsion can be obtained at a mass ratio of 1∶ 3∶ 7 of garlic oil,ethanol and Tween 80. It can be diluted in any proportion of water and form a clear nano- emulsion. For instance,the ten- fold water diluted emulsion included a large number of nano- emulsion droplet with an average diameter of 36. 1 nm.Further,this pre- emulsion can be kept in stable state for six months without any obvious change of composition and dispersion state under closed circumstance and temperature 40 ℃.
