Objective: To optimize film-forming materials and additives of Zizhu Zhixue film coating agent with a satisfactory film-forming property. Method: Film-forming materials and additives were selected by synthetic weighted mark method with film-forming time and appearance quality as evaluation indexes. Result: Polyvinyl alcohol (PVA1788-PVA124 1∶3) dissolved by 90% ethanol as film-forming material
and added glycerin 1 mL and Tween -80 0.2 mL. This prepared Zizhu Zhixue film coating agent had advantages of short film-forming time and film-forming property was well. Conclusion: It suggested that these film-forming materials and additives in this test could be used for forming process of Zizhu Zhixue film coating agent.
