1. Hydroxypropyl methyl cellulosewairewa i roto i te wai matao, wai wera memeha ka tutaki uaua. Engari he tino teitei ake te pāmahana o te wai wera i tera o te methyl cellulose. Ko te whakarewatanga o te methyl cellulose i roto i te wai matao ka tino pai ake.
2. Ko te viscosity o te hydroxypropyl methyl cellulose e pa ana ki tona taumaha ngota, a, ko te nui o te taumaha o te ngota ko te teitei ake o te viscosity. Ka pa ano te pawera ki tona pokey, ka piki ake te pāmahana, ka heke te pokey. Heoi, he iti ake te pokey o te pāmahana teitei i to te methyl cellulose. Ka noho pumau te otinga ina rongoa ki te pāmahana rūma.
3. Ko te Hydroxypropyl methyl cellulose he pumau ki te waikawa me te kawakawa, a he tino pumau tona otinga wai i roto i te awhe o te pH = 2 ~ 12. Karekau he painga nui o te houra me te wai kotakota ki ona taonga, engari ka taea e te alkali te whakatere i tona reiti memeha me te whakapai ake i te poiketa o te titi. Hydroxypropyl methyl cellulose he pumau ki nga tote whanui, engari ka nui te kukū o te wairewa tote, ka piki ake te pokey o te wairewa hydroxypropyl methyl cellulose.
4. Ko te pupuri wai o te hydroxypropyl methyl cellulose ka whakawhirinaki ki te nui o te taapiri, te pokey, me etahi atu.
5. Ko te whakapiringa o te hydroxypropyl methyl cellulose ki te hanga kumete he teitei ake i tera o te methyl cellulose.
6. Hydroxypropyl methyl cellulosehe pai ake te aukati i te methyl cellulose i te methyl cellulose, a he iti ake te kaha o te paheketanga enzymatic i roto i te otinga i te methyl cellulose.
