Gabatarwa:
Hydroxypropylmethylcellulose (HPMC) da hydroxyethylcellulose (HEC) duka abubuwan da aka saba amfani da su a cikin abinci, kayan kwalliya da masana'antar harhada magunguna.Waɗannan abubuwan da suka samo asali na cellulose suna da fa'idodin aikace-aikacen sabili da keɓancewar ruwa na musamman, kwanciyar hankali mai kauri, da kyakkyawan ikon ƙirƙirar fim.
1.Tsarin sinadarai:
HPMC polymer roba ce da aka samu daga cellulose.Ana yin ta ne ta hanyar gyaggyarawa na halitta cellulose ta hanyar ƙara propylene oxide da methyl chloride.HEC kuma wani nau'i ne na cellulose, amma ana yin shi ta hanyar mayar da cellulose na halitta tare da ethylene oxide sannan a yi masa magani da alkali.
2. Solubility:
Dukansu HPMC da HEC suna da ruwa mai narkewa kuma ana iya narkar da su cikin ruwan sanyi.Amma solubility na HEC ya kasance ƙasa da HPMC.Wannan yana nufin HPMC yana da mafi kyawun tarwatsewa kuma ana iya amfani dashi cikin sauƙi a cikin tsari.
3. Dankowa:
HPMC da HEC suna da halaye daban-daban na danko saboda tsarin sinadarai.HEC yana da mafi girman nauyin kwayoyin halitta da tsari mai yawa fiye da HPMC, wanda ke ba shi danko mafi girma.Saboda haka, HEC ne sau da yawa amfani da matsayin thickener a formulations bukatar high danko, yayin da HPMC da ake amfani da formulations bukatar ƙananan danko.
4. Yin Fim:
Dukansu HPMC da HEC suna da ingantattun damar ƙirƙirar fim.Amma HPMC yana da ƙananan zafin jiki na fim, wanda ke nufin ana iya amfani dashi a ƙananan zafin jiki.Wannan ya sa HPMC ya fi dacewa don amfani a cikin abubuwan da ke buƙatar lokutan bushewa da sauri da mafi kyawun mannewa.
5. Kwanciyar hankali:
HPMC da HEC sun tabbata a ƙarƙashin mafi yawan pH da yanayin zafi.Koyaya, HEC ya fi kulawa da canje-canjen pH fiye da HPMC.Wannan yana nufin cewa ya kamata a yi amfani da HEC a cikin tsararraki tare da kewayon pH na 5 zuwa 10, yayin da ana iya amfani da HPMC a cikin kewayon pH mai fadi.
6. Aikace-aikace:
Halaye daban-daban na HPMC da HEC sun sa su dace da aikace-aikace daban-daban.Ana amfani da HEC a matsayin wakili mai kauri a cikin kayan kwalliya da magunguna.Hakanan ana amfani dashi azaman mai ɗaure da mai samar da fim a cikin ƙirar kwamfutar hannu.Ana amfani da HPMC azaman mai kauri, stabilizer, da wakili mai ƙirƙirar fim a cikin kayan abinci, magunguna, da kayan kwalliya.Hakanan ana amfani dashi azaman wakili na gelling a wasu aikace-aikacen abinci.
A ƙarshe:
HPMC da HEC duka abubuwan haɓakar cellulose ne tare da kaddarorin musamman waɗanda suka dace da aikace-aikace daban-daban.Fahimtar bambance-bambancen da ke tsakanin waɗannan additives guda biyu na iya taimaka maka zaɓi wanda ya dace don girke-girke.Gabaɗaya, HPMC da HEC amintattu ne kuma ingantaccen ƙari waɗanda ke ba da fa'idodi da yawa ga masana'antar abinci, kayan kwalliya da masana'antar harhada magunguna.
