Methylcellulose (MC) da Hydroxypropyl Methylcellulose (HPMC) duka biyun ana amfani da su ta hanyar ruwa mai narkewar ruwa, ana amfani da su sosai a abinci, magunguna, gini da kulawa na sirri.
1. Bambance-bambancen tsari
Methylcellulose (MC):
Methylcellulose wani nau'in cellulose ne wanda aka samu ta hanyar maye gurbin wani ɓangare na ƙungiyoyin hydroxyl na cellulose tare da methyl (-OCH3).
Tsarin sinadaransa yana da sauƙi, galibi ya ƙunshi kwarangwal na cellulose da maye gurbin methyl.
Hydroxypropyl Methylcellulose (HPMC):
An kafa HPMC ta hanyar ƙara gabatar da wani madaidaicin hydroxypropyl (-C3H7O) akan tushen methylcellulose.
Wannan canjin tsarin ya sa ya fi dacewa ta fuskar solubility da halayen danko a cikin ruwa.
2. Solubility
Methylcellulose yana da sauƙin narkewa a cikin ruwan sanyi, amma ba a sauƙaƙe a cikin ruwan zafi ba, kuma yawanci yana nuna yanayin colloidal. Wannan yana sa kaddarorin MC na iya canzawa lokacin da zafin jiki ya tashi.
Ana iya narkar da Hydroxypropyl Methylcellulose da kyau a cikin ruwan sanyi da ruwan zafi, kuma solubility ɗinsa ya fi na methylcellulose kyau. Har yanzu HPMC na iya kula da narkewar ruwa a yanayin zafi mai yawa kuma ya dace da aikace-aikacen da ke buƙatar maganin zafi.
3. Danko halaye
Methylcellulose yana da ɗanɗano kaɗan kuma ya dace da abubuwan da ba sa buƙatar babban danko.
Hydroxypropyl methylcellulose yana da danko mafi girma kuma ana iya daidaita shi ta canza nauyin kwayoyinsa da matakin maye gurbinsa. Wannan yana sa HPMC ta fi sauƙi a aikace-aikace iri-iri, musamman a masana'antar gine-gine da kuma magunguna.
4. Yankunan aikace-aikace
Ana amfani da Methylcellulose sau da yawa a cikin masana'antar abinci azaman mai kauri, emulsifier da stabilizer, kuma ana amfani dashi a cikin wasu samfuran magunguna azaman abin rufewa na magunguna.
Hydroxypropyl methylcellulose yana da aikace-aikacen da ya fi girma. Baya ga kayan abinci da magunguna, ana kuma amfani da shi sosai wajen kayan gini (kamar busasshen turmi) da kayayyakin kula da mutum (kamar kirim ɗin fata da shamfu) saboda kyawawan halayensa na yin fim da mannewa.
5. Halayen ayyuka
Methylcellulose yana da kyakkyawar riƙewar ruwa da abubuwan ƙirƙirar fim kuma galibi ana amfani dashi a cikin samfuran da ke buƙatar riƙe danshi.
Hydroxypropyl methylcellulose yana da kyakkyawan juriya na zafi da kyawawan abubuwan samar da fim ban da riƙe ruwa, don haka yana aiki mafi kyau a aikace-aikace tare da babban maganin zafin jiki.
6. Aminci da kwanciyar hankali
Dukansu addittun abinci marasa guba ne kuma galibi ana ɗaukar su lafiya. Koyaya, ana iya fifita HPMC a wasu aikace-aikace saboda ingantacciyar kwanciyar hankali da dacewarta.
Methylcellulose da hydroxypropyl methylcellulose sun bambanta sosai a tsarin sinadarai, solubility, halayen danko da wuraren aikace-aikacen. Zaɓin kayan da ya dace sau da yawa ya dogara da bukatun takamaiman aikace-aikacen. MC ya dace da aikace-aikacen kauri mai sauƙi da daidaitawa, yayin da HPMC ya fi dacewa da aikace-aikacen masana'antu masu rikitarwa da na kasuwanci saboda mafi girman solubility da ƙarfin daidaitawa.
