HPMC akhoza kusungunuka mu zosungunulira wothira madzi ozizira ndi zinthu organic kupanga mandala viscous njira. Njira yothetsera madzi imakhala ndi zochitika zapamtunda, zowonekera kwambiri komanso kukhazikika kwamphamvu. Kusungunuka kwake m'madzi sikukhudzidwa ndi pH. Imakhala ndi zokhuthala komanso zoletsa kuzizira mu shampoo ndi shawa gel, ndipo imakhala ndi madzi osungira komanso kupanga mafilimu abwino a tsitsi ndi khungu. Chifukwa cha kuchuluka kwa zida zopangira, cellulose (antifreeze thickener) amatha kuchepetsa mtengo wake ndikupeza zotsatira zabwino akagwiritsidwa ntchito mu shampo ndi gel osamba.
Madzi ozizira a tsiku ndi tsiku a hydroxypropyl methyl cellulose ali ndi izi zogulitsa:
1. Kuchita bwino kwambiri posungira madzi. HPMC ili ndi mawonekedwe a hydrophilic. Ikhoza kusunga madzi ochuluka mu phala, phala ndi phala.
2. Madzi ozizira nthawi yomweyo hydroxypropyl methylcellulose HPMC amagwiritsa ntchito zipangizo zachilengedwe, zomwe zimakhala ndi zofewa, zosapsa mtima, zoteteza chilengedwe ndi chitetezo.
3. PH imakhala yokhazikika, ndipo kukhuthala kwa njira yamadzimadzi nthawi zambiri kumakhala kokhazikika pa pH3.0 mpaka 11.0.
4. Njira yamadzimadzi ya mankhwalawa imakhala ndi ntchito yapamwamba, emulsification, chitetezo cha colloid ndi kukhazikika kwachibale. Kuvuta kwake pamtunda ndi pafupifupi 2% ndipo njira yamadzimadzi ndi 42-56dyn / cm.
5. Kukhuthala ndi kusungunuka kwamadzi, kumatha kusungunuka mwachangu m'madzi ozizira, zosungunulira za organic ndi zosakaniza ndi zosungunulira organic.
6. Wonjezerani kukhuthala: pamene kusungunuka kwakung'ono kumawonjezeka, njira yowonekera yowonekera idzapangidwa, yomwe ili ndi zizindikiro za ntchito yokhazikika komanso yowonekera kwambiri. The solubility adzasintha ndi mamasukidwe akayendedwe. M'munsi mamasukidwe akayendedwe, kwambiri mlingo wa kuvunda, amene bwino bwino otaya bata la dongosolo.
7. Kukana mchere wabwino kwambiri. HPMC ndi si-ayoni polima, amene ali wokhazikika mu organic electrolyte amadzimadzi njira kapena organic electrolyte.
8. Thermal gelation: pamene njira yamadzimadzi imatenthedwa ndi kutentha kwina, imakhala yosamveka mpaka dziko la flocculation lipangidwa, zomwe zidzapangitsa kuti yankho liwonongeke. Komabe, zidzasintha kukhala njira yothetsera vutoli pambuyo pozizira. Kwa vuto la gel osakaniza, kutentha makamaka kumadalira mtundu wa mankhwala, ndende ya yankho ndi kutentha kwa kutentha.
9. HPMC ili ndi katundu wina pa ntchito ya tsiku ndi tsiku ya mankhwala, monga mafilimu abwino kwambiri opanga mafilimu, kukana kwa enzyme, kubalalitsidwa ndi kugwirizanitsa katundu.
