Ko te HPMC he miro cellulose tino parakore hei rauemi mata, i raro i nga tikanga kawakore na roto i te etherification motuhake me te whakarite.White ma te paura ma ranei.HPMC heke ki te hekenga o te ihirangi methoxide, te piki o te ira gel, te heke o te wairewa wai me te heke o te mahi mata.
He kaha te kaha o te HPMC, te tote tote, te paura pungarehu iti, te pumau o te pH, te pupuri i te wai, te pumau o te ahua, te hanga kiriata pai, me te whānuitanga o te aukati, te marara me te piri.
HPMC, Hydroxypropyl Methylcellulose momo o te kore-ionic cellulose ether, he paura o te ma ki te tae ma atu, e mahi rite te thickener, here, kiriata-mua, surfactant, colloid tiaki, whakahinuhinu, emulsifier me te whakatārewatanga me te āwhina pupuri wai. I tua atu, kei reira nga momo ethers cellulose e whakaatu ana i nga ahuatanga o te waiariki waiariki, te koretake o te metabolic, te aukati i te whaariki, te iti o te kakara me te reka, me te pumau o te PH.
Na te tini o nga taonga, ka whakamahia te HPMC ki te whakakapi i etahi atu taapiri me te iti o te kukū, te hanga i te HPMC he taapiri tino pai me te whai hua i roto i nga waahanga whakapiri, hanga, kai, hua whare, rongoa me etahi atu.
