I-Hydroxypropylmethylcellulose (HPMC) yikhemikhali yekhemikhali esetyenziswa ngokubanzi kumashishini amaninzi ngenxa yokuguquguquka kwayo kunye neempawu ezizodwa.I-HPMC luhlobo lwe-ether yeselulosi, ephuma kwi-cellulose ye-polymer yendalo.
Esinye sezona zicelo zixhaphakileyo ze-HPMC kumashishini axuba amayeza okwenziwa kotyatyazo lwamachiza, izinto zokuncamathelisa kunye nezinye izinto ezincedisayo.I-HPMC ikwasetyenziswa kushishino lokutya njenge-thickener, emulsifier and stabilizer.Ukongeza, isetyenziswa kwamanye amashishini amaninzi afana nokhathalelo lomntu, ulwakhiwo kunye nemveliso yelaphu.
Kukho iintlobo ezimbini eziphambili zee-HPMC ezisetyenziswa ngokubanzi.Ukuchithwa kweentlobo ze-HPMC zezi: ukunyibilika ngokukhawuleza kwe-HPMC kunye nokunyibilika okucothayo kwe-HPMC.
I-HPMC ekhawulezileyo luhlobo lwe-HPMC enenqanaba eliphezulu lokuthatha indawo.Oku kuthetha ukuba inani le-hydroxypropyl kunye namaqela e-methyl afakwe kwi-cellulose backbone iphezulu kakhulu.Eli nqanaba liphezulu lokutshintshwa likhokelela kwi-HPMC enyibilikayo emanzini, enyibilika ngokukhawuleza emanzini.
I-HPMC ekhawulezileyo inosetyenziso oluninzi kwishishini lamayeza.Ihlala isetyenziswa njenge-disintegrant ukunceda iipilisi kunye ne-capsules ukuba ziphule zibe ngamancinci amancinci ngokukhawuleza.Oku kubalulekile kuba kuvumela ukukhutshwa ngokukhawuleza kwesithako esisebenzayo, esinokuba luncedo kwizicelo ezithile, ezifana neyeza zentlungu ezikhawulezayo.
I-HPMC enyibilikayo ngokukhawuleza ikwasetyenziswa njengesibophelelo kwiipilisi kunye nee-capsules.Inceda ukubamba i-tablet okanye i-capsule kunye kunye nokuphucula iimpawu zokuhamba kwezinto ezinomgubo ezisetyenziselwa ukwenza ithebhulethi okanye i-capsule.
Kushishino lokutya, i-HPMC ekhawulezileyo isetyenziswa njenge-thickener, emulsifier and stabilizer.Kuyanceda ukunika ukutya ukuthungwa okugudileyo kunye nokwandisa ubomi babo beshelufu.
Ukunyibilika okucothayo HPMC yenye HPMC kunye iqondo elisezantsi endaweni.Oku kuthetha ukuba ayinyibiliki kancinci emanzini kune-HPMC enyibilikayo ngokukhawuleza kwaye ithatha ixesha elide ukunyibilika emanzini.
Ukunyibilika okucothayo i-HPMC iqhele ukusetyenziswa njenge-arhente yokukhululwa ezinzileyo kwishishini loxubo mayeza.Ingasetyenziselwa ukwenza iipilisi kunye ne-capsules ezikhupha isithako esisebenzayo ngokucothayo kwithuba lexesha.Oku kunokuba luncedo kwizicelo ezithile, ezifana nonyango lweentlungu ezingapheliyo.
I-HPMC enyibilikayo kancinane ikwasetyenziswa kumashishini okhathalelo lomntu kunye nezithambiso.Isetyenziswa njenge-thickener, emulsifier kunye ne-stabilizer kwiimveliso ezininzi ezifana ne-shampoos, i-lotions kunye ne-creams.
Kushishino lolwakhiwo, ukunyibilika kancinane iHPMC isetyenziswa njengento etyebisayo yeemveliso ezisekwe kwisamente.Inceda ukuphucula ukusebenza kwesamente kunye nokuphucula ukunamathela kwemveliso kumphezulu.
Kushishino lwamalaphu, ukunyibilika ngokucothayo HPMC isetyenziswa njenge arhente yokulinganisa.Inceda ukwandisa amandla kunye nokuqina kwefiber, enokuphucula umgangatho we-textile egqityiweyo.
Ngokubanzi, zombini ukunyibilika okukhawulezayo kunye nokunyibilika kancinane HPMCs ezininzi iipropati eziluncedo kwaye ufumane izicelo kumashishini ezahlukeneyo.Ezi ntlobo zimbini ezinyibilikayo ze-HPMC zibonelela abavelisi uluhlu lweenketho xa ukhetha i-ether eselulosi kwisicelo sabo esithile.
Ukuqukumbela, i-HPMC iyikhompawundi eguquguqukayo kwaye iluncedo enezicelo ezininzi kumashishini ahlukeneyo.Iindidi ezahlukeneyo ze-HPMC, ezifana ne-HPMC yokunyibilika ngokukhawuleza kunye ne-HPMC yokuqhawula kancinane, ibonelela abavelisi ngoluhlu lweenketho xa bekhetha ii-ether ze-cellulose kwizicelo zabo ezithile.Kubalulekile ukuqaphela ukuba i-HPMC yikhompawundi ekhuselekileyo nesetyenziswa ngokubanzi ephandwe ngokubanzi kwaye yavavanywa, kwaye ibonelela ngeenzuzo ezininzi kubavelisi kunye nabathengi.
