Ko te Carboxymethyl cellulose (Carboxymethyl cellulose) ka hangaia e te hohenga o te roopu hydroxyl o te wae anhydroglucose i runga i te mekameka cellulose me te roopu etherification (chloro Z acid or ethylene oxide);
He matū amorphous kore tae ka rewa i roto i te wai, te wairewa alkali wai, te haukini me te otinga cellulose, kare e rewa i roto i te wairewa waro me te hinu kohuke;ka taea te whakamahi i te rahinga, te maramataka me te maataki matotoru i roto i te umanga pueru;
He kaihoko hanganga i roto i te hanga pepa me te papa;
Te reabsorption o nga poke i roto i nga taputapu horoi waihanga;
He kaihoko maanu mo te kowhiri i te parahi-nickel me te ore konupora;
Ko te whakakao me te whakapumau i te wa e keri ana nga puna hinu me te hau;
hanganga kāpia mo te pepapātū;
nga waahanga hangahanga maroke;
Nga waahanga peita wai tawhetawhe, aha atu.
Ko te Hydroxypropyl methylcellulose (Hypromellose, Cellulose) he mea hanga mai i te cellulose miro tino parakore hei rauemi mata, he mea whakahiato i raro i nga tikanga kawakore, a kaore he kai kaha penei i nga whekau kararehe me nga hinu.Wairewa i roto i te wai me te nuinga o nga wahanga polar me te tika o te waiwaro/wai, propanol/wai, dichloroethane, me etahi atu, kare e rewa i roto i te etera, te acetone, me te ewaro tino, ka pupuhi ki roto i te wairewa colloidal marama, paku puhoi ranei i roto i te wai matao.Ko te wairewa wai he mahi mata, he tino marama me te mahi pumau.
Kei a HPMC te taonga o te waiariki waiariki.Ka whakamahana te wairewa wai hua ki te hanga i te reera ka heke, ka memeha i muri i te whakamatao.He rereke te pāmahana gelation o nga whakaritenga rereke.He rereke te wairewa ki te pokey.Ko te iti o te pokey, ka nui ake te whakarewatanga.He rereke nga ahuatanga o te HPMC ki o raatau ahuatanga.Ko te whakakorenga o te HPMC i roto i te wai kaore e pa ki te uara pH.
