Ko te Hydroxypropyl methyl cellulose (HPMC) he pūmua kore-ionic, he ether cellulose kore-ionic i hangaia mai i te rauemi pūmua tūturu cellulose. He paura ma kore kakara te hua, kāore he reka, kāore he paitini, ka taea te rewa ki te wai matao hei hanga i tētahi otinga matotoru mārama, me te whakamātotoru, te here, te marara, te whakaemulsifying, te hanga kiriata, te whakatārewatanga, te mimiti, te whakapūmau, te mahi mata, me ngā āhuatanga pēnei i te pupuri makuku me ngā colloid tiaki.
Ko te HPMC inamata te nuinga e whakamahia ana i roto i ngā matū kakahu, ngā hua horoi matū o ia rā, ngā mea whakapaipai me ētahi atu mara; pērā i te hopi horoi, te horoi tinana, te horoi kanohi, te hinu, te kirīmi, te tiēre, te toner, te whakangawari makawe, ngā hua whakapaipai, te paraihe niho, te huware, te wai mirumiru taonga takaro, me ētahi atu.
Ko ngā āhuatanga hua o te hydroxypropyl methyl cellulose matū o ia rā ko:
1. Ngā rauemi mata taiao, he iti te riri, he ngawari te mahi, he haumaru me te tiaki taiao;
2. Te wairewatanga wai me te matotoru: ka taea te rewa tonu i roto i te wai matao, ka rewa i roto i ētahi whakarewa waro me te ranunga o te wai me ngā whakarewa waro;
3. Te matotoru me te whakanui ake i te matotoru: mā te pikinga iti o te whakarewatanga ka puta he otinga matotoru mārama, he mārama teitei, he pumau te mahi, ka huri te wairewa me te matotoru, ko te iti o te matotoru, ko te nui ake o te wairewa; ka pai ake te pumau o te rere o te pūnaha;
4. Ātete tote: He pūhui kore-ionic te HPMC, he pumau tonu i roto i ngā otinga wai o ngā tote whakarewa, ngā irahiko waro rānei;
5. Te ngohe o te mata: he ngohe mata te otinga wai o te hua, ā, he mahi me ngā āhuatanga o te emulsification, te colloid tiaki me te pumau whanaunga; ko te kukū o te mata: ko te 2% otinga wai he 42-56dyn/cm;
6. Te pumau o te PH: he pumau te matotoru o te wairewa i roto i te awhe PH3.0-11.0;
7. Pānga pupuri-wai: ka taea te tāpiri i te āhuatanga hydrophilic o te HPMC ki ngā hua paru, whakapiri me ngā hua pasty hei pupuri i te pānga pupuri-wai teitei;
8. Te whakawera wera: Ina whakamahanatia te wairewa ki tētahi pāmahana, ka noho pōuriuri tae noa ki te hanga i tētahi āhua whakapūpū (poly), ka ngaro te matotoru o te wairewa. Engari i muri i te whakamatao, ka hoki anō ki tōna āhua taketake. Ko te pāmahana e puta ai te āhuatanga whakapūpū ka whakawhirinaki ki te momo hua, te kukū o te wairewa me te tere whakamahana;
9. Ētahi atu āhuatanga: he tino pai ngā āhuatanga hanga kiriata, me te whānuitanga o te ātete ki ngā whākōkī, te marara me te piripono, me ētahi atu.
