Daily chemical grade hydroxypropyl methylcellulose ndi polima opangidwa kuchokera ku cellulose wachilengedwe kudzera kusinthidwa kwa mankhwala. Cellulose ether ndi chochokera ku cellulose yachilengedwe. Kupanga kwa cellulose ether ndikosiyana ndi ma polima opangira. Zinthu zake zofunika kwambiri ndi cellulose, gulu lachilengedwe la polima.
Chifukwa cha mawonekedwe achilengedwe a cellulose, mapadi pawokha sangathe kuchitapo kanthu ndi etherification agents. Komabe, pambuyo pochiza chotupa chotupa, zomangira zamphamvu za haidrojeni pakati pa unyolo wa maselo ndi unyolo zimawonongeka, ndipo kutulutsidwa kogwira kwa gulu la hydroxyl kumakhala cellulose yotakata. Pambuyo pakuchita kwa etherifying agent, gulu la -OH limasinthidwa kukhala gulu OR Pezani cellulose ether. The 200,000-viscosity hydroxypropyl methylcellulose kwa "Max" kalasi yamankhwala tsiku ndi tsiku ndi ufa woyera kapena wachikasu pang'ono, womwe umakhala wopanda fungo, wosakoma komanso wopanda poizoni. Iwo akhoza kusungunuka m'madzi ozizira ndi osakaniza zosungunulira organic nkhani kupanga mandala viscous njira.
Madzi ogwiritsira ntchito madzi amakhala ndi zochitika zapamtunda, kuwonekera kwambiri, kukhazikika kwamphamvu, ndipo samakhudzidwa ndi pH akasungunuka m'madzi. Ili ndi zotsatira zokhuthala komanso zoletsa kuzizira mu shampoos ndi ma gels osambira, ndipo imakhala ndi madzi osungira komanso kupanga mafilimu abwino a tsitsi ndi khungu. Ndi kukwera kwakukulu kwa zida zoyambira, kugwiritsa ntchito cellulose (antifreeze thickener) mu shampoo ndi gel osamba kumatha kuchepetsa mtengo ndikukwaniritsa zomwe mukufuna.
