Embodiment 1
[0028] Taking the preparation of 100g of antibacterial agent for sanitary napkins as an example, the raw materials and their quality are as follows:
[0029]
[0030] 1) To prepare clathrates, weigh 50g of β-cyclodextrin and place it in a reaction kettle, add 200ml of water and heat and stir until the β-cyclodextrin is completely dissolved, and continue to heat up to 55°C to make a saturated aqueous solution; weigh 5g of Dissolve triclosan in 5ml of propylene glycol, slowly add it into the reaction kettle containing β-cyclodextrin under stirring condition, continue heating and stirring for 2h, concentrate the solution under reduced pressure to 50ml, refrigerate overnight at 4°C, filter out the precipitate, and then Dry at 90°C for 1 hour to obtain triclosan-cyclodextrin inclusion compound, which is a white powder;
[0031] 2) Weigh the triclosan cyclodextrin inclusion compound prepared in step 1), and citric acid, sodium citrate, potassium sorbate, carbomer, and soluble sta...
Embodiment 2
[0034] Taking the preparation of 100g of antibacterial agent for sanitary napkins as an example, the raw materials and their quality are as follows:
[0035]
[0036] 1) To prepare clathrates, weigh 40g of β-cyclodextrin and place it in a reaction kettle, add 200ml of water and heat and stir until the β-cyclodextrin is completely dissolved, and continue to heat up to 65°C to make a saturated aqueous solution; weigh 5g of Dissolve triclosan in 5ml propylene glycol, slowly add it into the reaction kettle containing β-cyclodextrin under stirring condition, continue heating and stirring for 4h, concentrate the solution under reduced pressure to 50ml, refrigerate overnight at 4°C, filter out the precipitate, and then Dry at 90°C for 1 hour to obtain triclosan-cyclodextrin inclusion compound, which is a white powder;
[0037] 2) Weigh the triclosan cyclodextrin inclusion compound prepared in step 1), and citric acid, sodium citrate, potassium sorbate, carbomer, and soluble starch...
Embodiment 3
[0040] Taking the preparation of 100g of antibacterial agent for sanitary napkins as an example, the raw materials and their quality are as follows:
[0041]
[0042] 1) To prepare clathrates, weigh 45g of 2-hydroxypropyl-β-cyclodextrin and place it in a reaction kettle, add 200ml of water and heat and stir until the β-cyclodextrin is completely dissolved, and continue to heat up to 70°C to make a saturated aqueous solution Weigh 5g of triclosan and dissolve it with 5ml of ethanol, slowly add it into the reaction kettle equipped with 2-hydroxypropyl-β cyclodextrin under stirring condition, continue heating and stirring for 7h, filter out the precipitate while it is hot, and then place Dry at 90°C for 1 hour to obtain triclosan-cyclodextrin inclusion compound, which is a white powder;
[0043] 2) Weigh the triclosan cyclodextrin inclusion compound prepared in step 1), and citric acid, sodium citrate, potassium sorbate, carbomer, and soluble starch, stir the above-mentioned s...
