Integrated test method for non-volatile content in plastic bottles for eye drop packaging
Abstract : Non-volatiles in pharmaceutical packaging will be dissolved into pharmaceutical products. In order to prevent the excessive amount of dissolution and affect the quality of pharmaceutical products, the non-volatile content in pharmaceutical packaging should be strictly controlled. In this paper, a non-volatile content in a brand of eye drop package is tested as an example. A test method integrating evaporation, drying, weighing and solution recovery is introduced, and the test principle, equipment C 830 migration amount and The parameters of the non-volatiles analyzer, the scope of application, the test process, etc., provide a reference for enterprises to monitor the non-volatile content in pharmaceutical packaging simply and effectively.

1 , meaning
The raw material resin and additives added to ensure the performance of the material are all sources of non-volatile substances in the pharmaceutical packaging. These non-volatile small molecular substances are not static inside the package, and are easily dissolved and transported into the pharmaceutical product. When the packaged product is a liquid medicament or in a high temperature environment, the dissolution rate and dissolution amount of the non-volatile matter are increased, and the dissolved substances are likely to contaminate the packaged medicine. At present, the testing of non-volatiles in pharmaceutical packaging requires an evaporation - drying - cooling - weighing process. The traditional test method is to evaporate the test solution containing the eluate in a water bath, then manually transfer it to an oven for drying, and then transfer. Cooling to the dryer, weighing with the balance after the Zui, the test process is cumbersome, human and environmental factors interfere with the test. The new method of non-volatiles integration testing introduced in this paper overcomes the above shortcomings of the traditional test method, realizes the complete automation of the evaporation - drying - cooling - weighing process, and has the function of soaking liquid recovery.

4.1 Test principle
Select the simulated material soaked in the packaging material similar to the nature of the packaged drug, dissolve the non-volatile matter, and evaporate and dry the test solution and the blank simulant to obtain the remaining residue, and subtract the blank simulant from the weight of the residue in the test solution. The weight of the residue is the non-volatile content of the tested packaging material.
4.2 Equipment parameters
The test range is 0.1 ~ 80,000 mg , the resolution is 0.01 mg ; the test temperature range is from room temperature to 130 °C , the temperature control accuracy is ±0.3 °C ; the evaporation, drying and weighing are integrated, and the automatic weighing can be carried out automatically. No need for manual participation; the volatile reagents can be collected and processed in the airtight system, and the requirements for the laboratory ventilation system are low; the international ling first quick evaporation technology is used to shorten the evaporation time; 9 station design, The test process is independent of each other and the test efficiency is high. Through the special design of the constant temperature cavity and the weighing system, the test accuracy of the device is greatly improved.

5 , the test process
(1) from a plastic eye drop bottle packaging flat portion sample sampling, to ensure that the inner surface area of the sample was 300 cm 2, cut into 3 cm × 0.3 cm pieces placed in a conical flask, 75 mL distilled water shocks Clear samples were removed and dried at 30 °C .
(2) 100 mL distilled water was added to the sample after drying, after capped sealed and placed for 24 h at 70 ℃.
(3) Take 50 mL of the test solution from the Erlenmeyer flask and place it in the evaporating dish which has been dried and weighed, and take the same volume of distilled water for the blank test.
(4) Place the evaporating dish containing the test solution and distilled water on the tray rack with the migration amount and the corresponding number of the test chamber of the non-volatiles tester , close the test chamber door, set the sample name, reagent evaporation temperature, and test temperature. Test parameters such as test mode and number of tests. The test is initiated and the device volatilizes, dries, and collects the volatile reagents from the evaporating dish.
(5) The equipment is automatically weighed according to the set parameters, and the measured value of the test evaporating dish, the blank evaporating dish and the non-volatile content are measured.
