Nws cov ntawv thov tseem ceeb suav nrog:
1. Nyob rau hauv cov khoom noj thiab cov txuj lom, nws tuaj yeem txhim kho kev ruaj ntseg thiab kev ua neej ntev ntawm cov khoom noj khoom haus molecules, daim npog ntsej muag lossis kho cov ntxhiab tsw thiab tsw ntawm cov khoom noj khoom haus molecules, thiab txhim kho cov txheej txheem ntau lawm thiab cov khoom zoo.
2. Raws li stabilizer, emulsifier, deodorant, thiab lwm yam hauv cov khoom siv tshuaj pleev ib ce, nws tuaj yeem txo qhov khaus ntawm cov organic molecules hauv cov tshuaj pleev ib ce rau ntawm daim tawv nqaij thiab mucous daim nyias nyias, txhim khu kev ruaj ntseg ntawm cov khoom xyaw nquag, thiab tiv thaiv cov volatilization thiab oxidation ntawm cov as-ham. Nws muaj qee yam txheeb ze hygroscopicity.
3. Hauv kev lag luam kws kho mob, vim nws qhov kev ua haujlwm qis qis thiab hemolytic kev ua haujlwm thiab tsis muaj kev ua xua rau cov leeg, nws yog ib qho zoo tagnrho solubilizer rau txhaj tshuaj thiab excipient rau tshuaj.
Cia
2-Hydroxypropyl- -cyclodextrin yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua zoo kom deb ntawm tshav ntuj ncaj qha, muaj zog acids/alkalis, thiab muaj zog oxidizing lossis txo cov neeg ua haujlwm.
kev tiv thaiv
1. Hnav cov hnab looj tes tiv thaiv tsim nyog thiab tsom iav kev nyab xeeb thaum tuav 2-Hydroxypropyl- -cyclodextrin kom tsis txhob pom qhov muag thiab tawv nqaij.
2. Siv qhov cua kom txaus lossis lub ntsej muag plua plav (N95) thaum tuav 2-Hydroxypropyl- -cyclodextrin hmoov kom tsis txhob nqus tau.
3. Ntxuav tes kom huv si tom qab tuav 2-Hydroxypropyl- -cyclodextrin thiab khaws 2-Hydroxypropyl- -cyclodextrin kom deb ntawm cov zaub mov thiab dej haus.
Kev pab thawj zaug
1. Yog tias nqus tau, txav 2-Hydroxypropyl- -cyclodextrin raug tus neeg tau txais huab cua ntshiab tam sim ntawd thiab sab laj nrog kws kho mob yog tias tsis xis nyob.
2. Yog hais tias nyob rau hauv qhov muag, yaug 2-Hydroxypropyl- -cyclodextrin kom huv si nrog dej kom ntau rau ob peb feeb thiab tshem tawm cov lo ntsiab muag yog tias muaj.
3. Yog tias nqos tau, yaug qhov ncauj nrog dej thiab tsis txhob muab ib yam dab tsi los ntawm qhov ncauj rau tus neeg tsis nco qab, ces mus ntsib kws kho mob.
