1, raw material selection: raw materials include chlorhexidine acetate, gelatin, glycerol, water, etc., of which, chlorhexidine acetate is the main active ingredient, its purity and quality directly affects the effect of the gel agent and safety, therefore, in the selection of chlorhexidine acetate should be prioritized to consider the purity of high quality and stability of the product.

2, the proportion of the formula: the proportion of different formulations will affect the viscosity, fluidity and stability of the gel agent performance, the content of chlorhexidine acetate should be between one and five percent, gelatin and glycerol content also need to be adjusted according to the specific circumstances.
