The invention discloses an anti-fog master batch for a polypropylene film. The anti-fog master batch is prepared from the following raw material components: polypropylene, maleic anhydride grafted polypropylene, sorbitan monopalmitate and polyimide. Secondly, the invention also discloses an antifogging polypropylene film, which is prepared by the following steps: preparing an antifogging master batch from polypropylene, maleic anhydride grafted polypropylene, polyimide and sorbitan monopalmitate; and uniformly mixing the anti-fog master batch with polypropylene, extruding the mixture into a strip-shaped or tubular film by adopting a screw extruder, and rolling and pulling the film to form the required width and thickness, thereby obtaining the anti-fog polypropylene film. According to the anti-fog polypropylene film, polyimide, maleic anhydride grafted polypropylene and sorbitan monopalmitate cooperate with one another and serve as a whole to jointly improve the hydrophilic performance of the anti-fog polypropylene film, so that the anti-fog performance of the anti-fog polypropylene film is greatly improved, and the water contact angle of the anti-fog polypropylene film can be lower than 10 degrees.

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
