Embodiment 1
[0032] A gynecological foam preparation prepared from the following raw materials by weight percentage: 1.0% chitosan, 1% acetic acid, 0.5% glycerin, 0.01% fatty alcohol polyoxyethylene ether, 1.5% alkanolamide, and the rest is purified water.
[0033] Described chitosan is through purification process, comprises the steps:
[0034] 1) Dissolve chitosan in water with a balance, and stir until completely dissolved to obtain the first solution;
[0035] 2) coarsely filter the first solution with a stainless steel screen to obtain the second solution;
[0036] 3) Filtrating the second solution for a second time to obtain a third solution; the second filtration uses a microporous membrane for high-pressure suction filtration.
[0037] 4) adding ethanol while stirring makes chitosan precipitate, and the volume ratio of ethanol and the third solution is 3:1; Then filter after centrifuging at a rotating speed of 6000 rpm for 30 minutes to obtain purified chitosan;
[0038] 5) Dry ...
Embodiment 2
[0055] A gynecological foam preparation is prepared from the following raw materials by weight percentage: 1.5% chitosan oligosaccharide, 0% acetic acid, 5% glycerin, 1.2% alkyl glycoside, and the rest is purified water.
[0056] Described chitosan oligosaccharide is through purification process, comprises the steps:
[0057] 1) Weigh the chitosan oligosaccharide with a balance and dissolve it in water, and stir until completely dissolved to obtain the first solution;
[0058] 2) coarsely filter the first solution with a stainless steel screen to obtain the second solution;
[0059] 3) Filtrating the second solution for a second time to obtain a third solution; the second filtration uses a microporous membrane for high-pressure suction filtration.
[0060] 4) Adding ethanol while stirring makes the chitosan oligosaccharide precipitate, and the volume ratio of ethanol to the third solution is 3:1; then centrifuges at a speed of 6000 rpm for 30 minutes and then filters to obtain ...
Embodiment 3
[0077] A gynecological foam preparation, prepared from the following raw materials by weight percentage: chitosan quaternary ammonium salt 0.5%, acetic acid 0%, glycerin 2%, alkyl glycoside 0.5%, Tween 0.01%, and the rest is purified water.
[0078] Chitosan quaternary ammonium salt is purified, including the following steps:
[0079] 1) Dissolve chitosan quaternary ammonium salt in water with a balance, and stir until completely dissolved to obtain the first solution;
[0080] 2) coarsely filter the first solution with a stainless steel screen to obtain the second solution;
[0081] 3) Filtrating the second solution for a second time to obtain a third solution; the second filtration uses a microporous membrane for high-pressure suction filtration.
[0082] 4) adding ethanol while stirring to precipitate chitosan quaternary ammonium salt, the volume ratio of ethanol to the third solution is 3:1; then centrifuge at 6000 rpm for 30 minutes and filter to obtain purified chitosa...
