6.1 Kev tiv thaiv los ntawm cov pa roj acids

• Kev tiv thaiv kev tiv thaiv: HPMC tuaj yeem muab kev tiv thaiv los ntawm cov ntsiav tshuaj kom dhau los ntawm lub plab thiab tso cov tshuaj hauv cov hnyuv.

7. Xim ruaj khov

7.1 UV kev tiv thaiv

• Xim Stability: HPMC tsho tiv thaiv tuaj yeem pab txhawb rau qhov ruaj ntseg ntawm cov xim, tiv thaiv kev ua kom muaj kev tiv thaiv lossis tsis zoo los ntawm qhov kaj.

8. Kev txiav txim siab thiab ceev faj

8.1 noj

• Ntse tshuaj tswj: cov tshuaj ntawm HPMC nyob rau hauv cov ntsiav tshuaj txheej yuav tsum tau ua tib zoo tswj kom ua tiav cov khoom uas xav tau yam tsis muaj kev cuam tshuam rau lwm yam ntxwv.

8.2 kev sib raug zoo

• Kev sib txuam: HPMC yuav tsum sib xws nrog lwm cov khoom xyaw ua kom muaj cov khoom xyaw, thiab cov khoom noj muaj zog, thiab cov txheej txheem ruaj khov los ua kom muaj kev ruaj khov thiab siv tau cov txheej txheem ruaj khov.

8.3 Kev tswj txoj cai

• Kev txiav txim siab: cov txheej txheem muaj HPMC yuav tsum ua raws li cov qauv kev cai lij choj thiab cov txheej txheem los xyuas kom muaj kev nyab xeeb thiab kev ua tau zoo.
