| Abstract: |
| Objective To optimize the recipes and conditions of preparing Imidocarb Dihydrochloride multiple emulsion. Methods Firstly, the best oil phase and emulgator and their concentrations, the oil-water proportion and emulsification conditions were determined for original emulsion preparation by means of orthogonal experiments as well as single element experiments. Secondly, the best emulgator of outside aqueous phase, the volume ratio of aqueous phase and original emulsion, stabilizer of inside aqueous phase and it’s dosage, and emulsification conditions were screened out for preparating Imidocarb Dihydrochloride multiple emulsion. Results The optimum conditions for original emulsion preparation were obtained by using mineral oil as oil phase, 10% of OP-10 as emulgator, 7:3 of oil-water proportion and the emulsification conditions were 40℃, 3min and 10000rpm. The optimal choices for multiple emulsion preparation were 7% of emulgator for outside aqueous phase, 5:5 of aqueous phase and original emulsion, 10% gel as stablizer and 25℃, 1min and 4000rpm emulsification. Conclusion The optimized the recipes and conditions of preparing Imidocarb Dihydrochloride multiple emulsion were determined. |
