Embodiment 1
[0051] Embodiment 1, preliminary experiment
[0052] (1. Purpose
[0053] Investigate the effect of the film-forming material polyvinyl alcohol polyethylene glycol copolymer (BASF company, pharmaceutical excipient approval number F20110024) and hydroxypropyl cellulose on the film-forming properties
[0054] (2) Methods and results
[0055] According to the water-soluble characteristics of hydroxypropyl cellulose, and considering that hydroxypropyl cellulose (HPC) is a temperature-sensitive cellulose derivative, too high a temperature will destroy the structure of hydroxypropyl cellulose or even To make it lose its viscosity, add water to swell and dissolve it, and prepare it with a mass concentration of 2.5%, 5%, 7.5%, and 10%, respectively, and the temperature increases (60°C, 70°C, 80°C, 90°C) when dissolving A series of hydroxypropyl cellulose film-forming solutions were spread on petri dishes by homogenate casting film-forming method, and dried naturally, and the appeara...
