Indawo Ephansi I-Hydroxypropyl Cellulose

I-Low Substituted Hydroxypropyl Cellulose (L-HPC) iyi-polymer ye-cellulose eguquliwe evame ukusetshenziswa njenge-thickener, binder, kanye ne-stabilizer ezimbonini ezihlukahlukene, ezihlanganisa ukudla, imithi, nemikhiqizo yokunakekelwa komuntu siqu. Itholakala ku-cellulose, okuyi-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.

I-L-HPC ikhiqizwa ukuguqulwa kwamakhemikhali e-cellulose kusetshenziswa inqubo ye-hydroxypropylation, lapho amaqembu e-hydroxypropyl (-CH2CH(OH)CH3) ethulwa ku-molecule ye-cellulose. Izinga lokushintsha, noma inombolo yamaqembu e-hydroxypropyl ngeyunithi ngayinye ye-glucose, ngokuvamile liphansi, lisuka ku-0.1 kuye ku-0.5.

Njenge-thickener, i-L-HPC ifana nezinye izingqimba ezisekelwe ku-cellulose, njenge-carboxymethyl cellulose (CMC) ne-methyl cellulose (MC). Uma i-L-HPC yengezwa emanzini, yakha isakhiwo esifana nejeli esikhulisa i-viscosity yesisombululo. I-viscosity yesisombululo incike ekugxilweni kwe-L-HPC kanye nezinga lokufaka esikhundleni. Ukuphakama kwe-L-HPC kanye nezinga eliphezulu lokushintsha, isisombululo sizoba sikhulu.

I-L-HPC ivamise ukusetshenziswa embonini yokudla njengokujiya nokuqiniswa emikhiqizweni eyahlukene, okuhlanganisa izimpahla ezibhakwayo, amasoso, kanye nezingubo zokugqoka. Ezimpahleni ezibhakiwe, i-L-HPC ingasetshenziselwa ukuthuthukisa ukuthungwa kanye nekhwalithi yomkhiqizo, ikakhulukazi ekwakhiweni okungenalo i-gluten. Kusoso kanye nezingubo zokugqoka, i-L-HPC ingasiza ekuthuthukiseni ukuzinza komkhiqizo, ivimbele ukuthi ungahlukanisi noma ube namanzi.

Embonini yezemithi, i-L-HPC isetshenziswa njenge-binder kanye ne-disintegrant kumaphilisi namaphilisi. Njengesibophezelo, i-L-HPC isiza ukubamba izithako ezisebenzayo ndawonye futhi ithuthukise izinga lokuqedwa kwethebhulethi noma i-capsule. Njenge-disintegrant, i-L-HPC isiza ukudiliza ithebhulethi noma i-capsule esiswini, okuvumela izithako ezisebenzayo ukuthi zimunceke ngokuphumelelayo.

I-L-HPC iphinde isetshenziswe embonini yokunakekelwa komuntu siqu njenge-thiener kanye ne-emulsifier emikhiqizweni eyahlukene, okuhlanganisa izinto zokuthambisa, okhilimu, nemikhiqizo yokunakekelwa kwezinwele. Kuma-lotions nama-creams, i-L-HPC isiza ukuthuthukisa ukuthungwa nokuvumelana komkhiqizo, iwunikeze umuzwa obushelelezi, nosilika. Emikhiqizweni yokunakekelwa kwezinwele, i-L-HPC ingasiza ekuthuthukiseni ukujiya nokuzinza komkhiqizo, ivimbele ukuthi ungahlukaniseki noma ube namanzi.

Enye yezinzuzo zokusebenzisa i-L-HPC njenge-thickener ne-stabilizer ukuthi iyisithako esingokwemvelo, esivuselelekayo esitholakala emithonjeni yezitshalo. Ngokungafani nama-thickeners nama-stabilizer okwenziwa, i-L-HPC iyabola futhi ihambisana nemvelo.
