Embodiment 1
[0040] Follow the steps below to prepare polymeric aqueous gels:
[0041] ① Weigh each raw material according to Table 1, pour carbomer, glycerin, and polysorbate into the stirring pot, start the agitator, add 80% volume of purified water, cover and stir well, and use in the next step;
[0042] ②Put the material in the previous step into the homogenizer. After homogenizing for 10 minutes, turn on the scraper agitator and the vacuum system, and the frequency of the stirring motor is 20Hz. When the vacuum in the pot reaches -0.05MPa, turn off the vacuum system and stir for 24 Obtain swelling material in hours;
[0043] ③ Dissolve NaOH and the remaining 20% volume of purified water in a water pot, and heat to 80°C to obtain NaOH solution;
[0044] ④Put the swollen material obtained in step ② into the emulsification pot, heat it, and when the temperature is 80°C, turn on the homogenizer, add the NaOH solution obtained in step ③ into the emulsification pot, homogenize for 5 minu...
Embodiment 2
[0054] The amount of raw materials is shown in Table 1, and the preparation method is the same as in Implementation 1. The obtained product is tasteless, non-irritating, transparent, has irregular bubbles, and has no other visible foreign impurities. It is a viscous colloid, no peculiar smell, and pH=6.8 , the dynamic viscosity is 6064mPa.s, and the microbial content is 10cfu / g, which meets the requirements for use. In clinical trials, the polymer water-based gel obtained in this embodiment has a total effective rate of 86.11% for patients with allergic rhinitis, while the same kind listed in the control group The effective rate of the product Mobijing is 66.6%, which shows that the polymer water-based gel of the present invention is superior to other similar products in treating allergic rhinitis, and has good preventive and auxiliary therapeutic effects on allergic rhinitis.
Embodiment 3
[0056] The amount of raw materials is shown in Table 1. The preparation method is the same as in Implementation 1. The obtained product is tasteless, non-irritating, transparent, has irregular bubbles, and has no other visible foreign impurities. It is viscous colloid, has no peculiar smell, and has a pH of 7.2 , the dynamic viscosity is 6462mPa.s, and the microbial content is 10cfu / g, which meets the requirements for use. In clinical trials, the total effective rate of the polymer water-based gel obtained in this embodiment can reach about 90% for patients with allergic rhinitis, while the control group The effective rate of Mobijing of the listed similar products is not more than 70%, which shows that the polymer water-based gel of the present invention is better than other similar products in the treatment of allergic rhinitis, and has better preventive and auxiliary therapeutic effects on allergic rhinitis .
