The invention discloses a preparation method of an ear canal cleaning bactericide containing dual-attribute substances, aiming at realizing the coexistence of dual-attribute substances through a special solvent and a solubilizer compound and a specific process; the technical points of the bactericide are as follows: Components by weight: 0.5% to 5% of anionic surfactant, 4% to 12% of solvent and solubilizer compound, 0.02% to 2% of cationic fungicide, and the balance is made up with deionized water; The specific compound combination and the specific addition order of the solubilizer improve the water phase structure, so that the bactericide can coexist stably in this immiscible system. The present invention perfectly integrates the anionic surfactant and the cationic bactericide, and then reflects their respective functions to maximize the efficacy of the product. |
