Hydroxyethylcellulose (HEC) is nonionic soluble cellulose ether inoshandiswa zvakanyanya mumaindasitiri akasiyana. HEC inotorwa kubva kune yakasikwa cellulose uye yakagadziridzwa kuti ive nemapoka ehydroxyethyl pane cellulose musana. Kugadziridzwa uku kunoita kuti HEC inyungudika zvakanyanya mumvura uye nezvimwe zvinonyungudutsa polar, zvichiita kuti ive yakanakira polima kune akasiyana maapplication.
Imwe yemashandisirwo ekutanga eHEC yakaita seyakakora uye inonamira mune dzakasiyana siyana dzevatengi uye maindasitiri zvigadzirwa. HEC inowanzoshandiswa muzvizoro uye zvigadzirwa zvekuchengeta munhu senge shampoos, lotions uye mishonga yemazino kuti ipe viscosity uye kugadzikana. Inoshandiswawo mupendi, machira uye zvinonamira kuti zvipe zvinonamira zvivakwa uye kugadzirisa hunyoro kuramba.
HEC inzvimbo yakasiyana-siyana yekuvaka yezvigadzirwa izvi nekuda kwekukwanisa kwayo kuwedzera viscosity mumvura-based systems pasina kunyanya kukanganisa zvimwe zvigadzirwa. Nekuwedzera HEC kune izvi zvigadzirwa, vagadziri vanogona kugadzirisa ukobvu, magadzirirwo uye kuenderana kwezvigadzirwa zvavo kuti zvisangane nezvinodiwa nevatengi uye zvinodiwa neindasitiri.
Kumwe kwakakosha kushandiswa kweHEC kuri muindasitiri yemishonga. HEC chinhu chinowanikwa mune zvakawanda zvigadzirwa zvemishonga, kusanganisira mahwendefa, capsules, uye masisitimu ekutumira zvinodhaka. Nekuda kwekugona kwavo kugadzirisa iyo rheology uye kuzvimba zvimiro zvedosage mafomu, HEC inogona kuwedzera bioavailability yezvinhu zvinoshanda zvinosanganisa uye kugadzirisa kutonga kwekuburitswa kwezvinodhaka. HEC inoshandiswawo kuvandudza kugadzikana kwe emulsions uye kumiswa mumishonga yemishonga.
Muindasitiri yezvekudya, HEC inoshandiswa seyakakora uye inodzikamisa mune dzakasiyana siyana zvigadzirwa zvekudya, zvinosanganisira sosi, madhirezi uye zvigadzirwa zvemukaka. HEC chinhu chakachengeteka, chechisikigo chinotenderwa kushandiswa muchikafu nemasangano anodzora pasi rese. Inoshandiswawo sechinzvimbo chemafuta muzvokudya zvakaderera-mafuta, zvichipa chimiro chakafanana uye muromo kune zvigadzirwa zvakazara-mafuta.
HEC inoshandiswawo muindasitiri yekuvaka seyakakora uye bhainda mune esimende zvigadzirwa senge magrouts, madhaka uye anonamira. Iyo thixotropic properties yeHEC inoita kuti ive chinhu chakakodzera chezvigadzirwa izvi, zvichivabvumira kuti varambe vari panzvimbo uye kudzivirira kusagika kana kugadzirisa. HEC ine kunamatira kuri nani uye kushomeka kwemvura, zvichiita kuti ive chinhu chakakosha mukudzivirira mvura uye kuisa chisimbiso zvigadzirwa.
Hydroxyethyl cellulose isiri-ionic soluble cellulose ether ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana. HEC chinhu chakasiyana-siyana uye chakakosha muzvigadzirwa zvakawanda zvevatengi uye zvemaindasitiri, zvichipa kugadzikana kwakawedzera, viscosity, uye kutonga kwekuburitswa kwezvinodhaka. HEC chinhu chechisikigo, chakachengeteka uye chine hushamwari chezvakatipoteredza icho chakatenderwa kushandiswa nenyika zhinji pasi rese. Yayo yakasarudzika zvimiro uye kuita kwakasiyana kunoita HEC chinhu chakakosha muzvigadzirwa zvakawanda uye maindasitiri.
