Hydroxypropyl methyl cellulose (HPMC) ndi polima wopanda ionic, ether yopanda ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe ya polima. The mankhwala ndi odorless, zoipa, sanali poizoni ufa woyera, akhoza kusungunuka m'madzi ozizira kupanga mandala viscous njira, ndi thickening, kugwirizana, dispersing, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba ntchito, Features monga monga kusunga chinyezi ndi colloids zoteteza.
Kalasi yomweyo HPMC zimagwiritsa ntchito mankhwala nsalu, tsiku mankhwala mankhwala kuyeretsa mankhwala, zodzoladzola ndi zina; monga shampu, kutsuka thupi, zotsukira kumaso, mafuta odzola, zonona, gel, tona, zotsitsira tsitsi, zopangira makongoletsedwe, mankhwala otsukira mano, Malovu, madzi otumphukira a chidole, etc.
Makhalidwe a mankhwala a tsiku ndi tsiku a hydroxypropyl methyl cellulose makamaka amaphatikizapo:
1. Zopangira zachilengedwe, kupsa mtima pang'ono, magwiridwe antchito, chitetezo ndi kuteteza chilengedwe;
2. Kusungunuka kwamadzi ndi kukhuthala: kumatha kusungunuka m'madzi ozizira nthawi yomweyo, kusungunuka muzosungunulira za organic ndi kusakaniza kwamadzi ndi zosungunulira za organic;
3. Kukula ndi kukhuthala-kuwonjezeka: kuwonjezeka pang'ono kwa kusungunuka kumapanga njira yowonekera yowonekera, yowonekera kwambiri, yokhazikika, kusintha kwa solubility ndi mamasukidwe akayendedwe, kutsika kwa kukhuthala, kumapangitsanso kusungunuka; bwino kusintha kuyenda bata kwa dongosolo;
4. Mchere kukana: HPMC ndi sanali ionic polima, ndi okhazikika mu njira amadzimadzi a mchere zitsulo kapena electrolytes organic;
5. Ntchito yapamtunda: njira yamadzimadzi ya mankhwalawa imakhala ndi ntchito yapamwamba, ndipo imakhala ndi ntchito ndi katundu wa emulsification, colloid yoteteza ndi kukhazikika kwachibale; Kuvuta kwa pamwamba ndi: 2% yankho lamadzi ndi 42-56dyn / masentimita;
6. Kukhazikika kwa PH: kukhuthala kwa njira yamadzimadzi kumakhala kokhazikika mkati mwa PH3.0-11.0;
7. Mphamvu yosungira madzi: katundu wa hydrophilic wa HPMC akhoza kuwonjezeredwa ku slurry, phala ndi zinthu za pasty kuti apitirize kusunga madzi;
8. Thermal gelation: Pamene njira yamadzimadzi imatenthedwa kutentha kwina, imakhala opaque mpaka imapanga (poly) flocculation state, yomwe imapangitsa kuti yankho liwonongeke. Koma pambuyo pa kuziziritsa, izo zidzasandulika kukhala njira yothetsera vutoli kachiwiri. Kutentha komwe kumachitika gel osakaniza kumachitika kumadalira mtundu wa mankhwala, ndende ya yankho ndi kutentha kutentha;
9. Makhalidwe ena: zinthu zabwino kwambiri zopanga mafilimu, komanso kukana kwa ma enzyme, dispersibility ndi cohesiveness, etc.
