Solubility na polymer, danko, da kaddarorin samar da fina-finai suna sauƙaƙe sakin magunguna, yana ba da damar ci gaba da isar da magunguna da aka yi niyya. Wannan yana da fa'ida musamman don haɓaka yarda da haƙuri da rage tasirin sakamako masu alaƙa da saurin sakin ƙwayoyi.
9. Kwanciyar hankali a ƙarƙashin mahallin pH daban-daban:
HPMC yana nuna kwanciyar hankali a kan kewayon pH mai faɗi, yana mai da shi dacewa da ƙirar da ke buƙatar kwanciyar hankali a ƙarƙashin yanayin acidic ko alkaline. Wannan kadarorin yana da fa'ida a cikin magunguna saboda ƙirar ƙwayoyi na iya haɗu da yanayin pH daban-daban a cikin sashin gastrointestinal.
10. Abubuwan Rheological:
Halin rheological na mafita na HPMC yana da mahimmanci ga aikace-aikace inda kaddarorin kwarara ke da mahimmanci, kamar a cikin shirye-shiryen sutura, adhesives da gels. Za a iya keɓance kaddarorin rheological ta hanyar daidaita taro da nauyin kwayoyin halitta na HPMC don cimma halaye masu gudana da ake buƙata don sarrafa e-madaidaicin.
Hydroxypropyl methylcellulose ya zama polymer mai mahimmanci a cikin masana'antu daban-daban saboda haɗin haɗin kai na musamman na solubility, danko, ikon samar da fina-finai da biocompatibility. Ƙwararrensa ya sa ya dace da aikace-aikace iri-iri, daga magunguna da kayan gini zuwa abinci da kayan shafawa. Yayin da masu bincike ke ci gaba da gano sabbin dabaru da aikace-aikace, kaddarorin hydroxypropyl methylcellulose babu shakka za su ba da gudummawa ga ci gaba a fannoni daban-daban, tare da tabbatar da ci gaba da mahimmancin kimiyyar kayan aiki da masana'antu.
