Test example 1
Delivered dose uniformity test
The nasal washes prepared in examples 1-5 were tested for delivery dose uniformity according to the chinese pharmacopoeia 2020 edition-general rule 0106 nasal formulation. The test results are shown in Table 1, and the test steps are as follows:
the nasal washes prepared in examples 1-5 were filled into 50mL spray bottles to obtain test samples, 10 bottles for each group. Shaking the sample to be tested for 5 seconds, and discarding 1 spray; after waiting at least 5 seconds, shaking the sample to be tested for 5 seconds, discarding 1 spray, and repeating the operation until discarding 5 sprays; after waiting for 2 seconds, the sample to be tested is placed in the normal position, the pressing device sprays the sample to be tested into the collecting device in a vertical spraying mode 1, the liquid medicine in the solvent collecting device is regulated under each variety item, the medicine amount in the collecting liquid is measured by the analysis method regulated under each variety item, and 10 bottles of the sample to be tested in each group are repeatedly measured.
Result determination conditions:
(1) Of the 10 measurements, if at least 9 measurements are between 75-125% of the average and all measurements are between 65-135% of the average.
(2) If 2-3 measured values exceed 75-125% in 10 measured results, 20 bottles of test samples should be additionally taken for measurement, and if 30 measured values exceed 75-125% in no more than 3 measured values, the total measured values are 65-135%.
One of the above conditions is satisfied, and it can be determined that the rule is satisfied.
Table 1 delivered dose uniformity test results
| Examples | Average measured value | Determination result |
| Example 1 | 78.5% | Qualified product |
| Example 2 | 95.0% | Qualified product |
| Example 3 | 86.4% | Qualified product |
| Example 4 | 104.8% | Qualified product |
| Example 5 | 115.8% | Qualified product |
Comparison of the delivered dose uniformity test of test example 1 shows that example 1 alone with the addition of verbena essential oil and zein, despite dilution with a large amount of water, affected dose delivery uniformity upon use due to non-aqueous dispersion; example 2 adding vervain essential oil and sodium alginate soluble in water, dose delivery uniformity was acceptable, but did not aid in the dispersibility of the vervain essential oil; example 3 addition of vervain essential oil, zein, sodium alginate alone, delivery uniformity was lower than that of sodium alginate with only water; the zein-sodium alginate composite dispersion emulsion is further prepared in examples 4 and 5, except that the verbena essential oil is directly added into the saline or the zein-sodium alginate composite dispersion emulsion is added into the saline, and compared with example 5, the zein-sodium alginate composite dispersion emulsion has good dispersibility and more uniform delivery dosage, so that the nasal wash has better use effect when being added into a spray bottle.
Test example 2
Appearance stability test
The nasal washes prepared in examples 1 to 5 were filled into 50mL spray bottles to obtain samples to be tested, and the samples were placed in a refrigerator and a constant temperature incubator, stored at 15℃and 25℃and 35℃for 24 hours, and subjected to an external stability test to see whether the nasal washes were layered, suspended and emulsified at room temperature, below room temperature and above room temperature, and the appearance of the nasal washes was recorded as non-clear liquid, and the test results were shown in Table 2.
TABLE 2 Low temperature storage and thermal stability test results
| Examples/temperatures | 15℃ | 25℃ | 35℃ |
| Example 1 | Non-clarified liquid | Non-clarified liquid | Non-clarified liquid |
| Example 2 | Non-clarified liquid | Non-clarified liquid | Non-clarified liquid |
| Example 3 | Non-clarified liquid | Non-clarified liquid | Non-clarified liquid |
| Example 4 | Non-clarified liquid | Clarifying solution | Non-clarified liquid |
| Example 5 | Clarifying solution | Clarifying solution | Clarifying solution |
Test example 2 comparison shows that the nasal washes of examples 1 to 5 were stored at 15℃and 25℃and 35℃for 24 hours, and that the appearance stability of example 5 was the best as shown in Table 2 comparison.
As can be seen from the comparison of the appearance stability test of the test example 2, the individual addition of the vervain essential oil and the zein in the example 1, the individual addition of the vervain essential oil and the sodium alginate in the example 2, the individual addition of the vervain essential oil, the zein and the sodium alginate in the example 3, the appearance stability of the examples 1-3 is low, the stability of the vervain essential oil is not helpful, and the vervain essential oil is not in a clear state after being stored for 24 hours at 15 ℃ and 25 ℃ and 35 ℃; the zein-sodium alginate composite dispersion emulsion is further prepared in examples 4 and 5, and is different in that the verbena essential oil is directly added into the saline or the zein-sodium alginate composite dispersion emulsion is added into the saline, and compared with the zein-sodium alginate composite dispersion emulsion, the zein-sodium alginate composite dispersion emulsion in example 5 has good appearance stability, and no appearance states such as layering, suspension, emulsification and the like appear after the zein-sodium alginate composite dispersion emulsion is stored at 15 ℃, 25 ℃ and 35 ℃ for 24 hours, so that the nasal wash has better use effect when being added into a spray bottle.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
