[0045]
[0046] The preparation process is as follows:
[0047] ⑴ Pre-preparation of functional ingredients: Weigh the prescription amount of benzalkonium chloride, rose sesame oil, VA64, and sodium lauryl sulfate and mix them evenly, add an appropriate amount of ethanol, and fully disperse in a high-speed homogeneous disperser for use.
[0048] ⑵ Preparation of blank film-forming stock solution: Weigh the prescribed amount of PVB, isooctane, ethyl cellulose, and ethyl oleate and mix them evenly, add the remaining amount of solvent, and mix well to make it completely dissolved.
[0049] ⑶ The spare solution of step (1) and the blank film-forming stock solution of step (2) are mixed thoroughly and poured into the spray device to obtain a liquid band-aid containing 0.2% benzalkonium chloride.
