Embodiment 1
[0019] Liquid nitrogen was used as the propellant, isopentane was selected as the dispersant or compatibilizer, and bromogeramine was used as a sterilizing agent. The ratio was 2 kg of liquid nitrogen, 7 kg of isopentane, 1 kg of bromogeramine, and 0.1 kg of Tween 80.
[0020] Isopentane and bromogeramine have suitable boiling points and are liquid at room temperature. Conventional production operations such as batching, stirring, and sub-packaging are very easy to control, and there is no need for equipment modification and major process condition changes during the production process.
[0021] Based on the above theoretical conditions, we conducted a series of experiments to verify:
[0022] 1) Solubility test of isopentane, bromogeramine, propellant liquid nitrogen, and Tween 80:
[0023] Test method: Mix isopentane, bromogeramine, liquid nitrogen and Tween 80 in a sealed thick glass bottle according to 7:1:2:0.1 (weight ratio), shake for 1 minute and let stand to observe w...
Embodiment 2
[0037] The propellant is liquid nitrogen, the dispersant or compatibilizer is cyclopentane, the sterilization and disinfectant is bromogeramine, the emulsifier is Tween 80, and the ratio is liquid nitrogen 2kg, cyclopentane 7kg, bromogeramine 1kg, Tween 80 is 0.1 kg. In the filling, the skin dressing Demoline powder produced by Jiangsu Yangsheng Bioengineering Co., Ltd. is used as the active ingredient, and the weight is 1kg. All the other are basically the same as Example 1.
Embodiment 3
[0039] The propellant is liquid carbon dioxide, the dispersant or compatibilizer is isopentane, the sterilization and disinfectant is bromogeramine, and the emulsifier is Tween 80. The ratio is 2kg of liquid carbon dioxide, 7kg of isopentane, 1kg of bromogeramine, and 0.1 kg of Tween 80. In the filling, the skin dressing Demoline powder produced by Jiangsu Yangsheng Bioengineering Co., Ltd. is used as the active ingredient, and the weight is 1kg. All the other are basically the same as Example 1.
