The invention belongs to the technical field of imbibition oil extraction, and provides a water-based nano-emulsion imbibition oil displacement agent and a preparation method thereof. According to the preparation method of the water-based nano-emulsion imbibition oil displacement agent, polyoxyethylene lauryl ether, sorbitan monopalmitate, mahogany petroleum sulfonate, an oily solvent, nano silicon oxide and water are uniformly mixed through a phase transition component method to prepare the water-based nano-emulsion imbibition oil displacement agent. The preparation method of the water-based nano-emulsion imbibition oil-displacing agent can effectively improve the crude oil recovery rate of unconventional oil reservoirs.

To provide a method for delivering a compound to the skin of a subject.SOLUTION: A method for delivering a compound to the skin of a subject includes topically applying an effective dose of one or more biphasic lipid vesicles to the skin of the subject, where the biphasic lipid vesicle contains one or more infiltration accelerators including (i) the compound and (ii) one or more nonionic detergents having approximately 10 or less of hydrophilic-lipophilic balance (HLB), and the one or more nonionic detergents having approximately 10 or less of HLB contains dimonomethylether oleyl ether, sorbitan monopalmitate, or polyoxyethylene (4) dilaurate.SELECTED DRAWING: Figure 1A-1
