Kwanciyar zafi:
polymer gabaɗaya yana nuna kyakkyawan kwanciyar hankali na thermal, yana ba da gudummawa ga haɓakarsa a cikin matakai daban-daban.
3. Haɗin kai:
Etherification:
Haɗin ya haɗa da etherification na cellulose tare da propylene oxide don gabatar da ƙungiyoyin hydroxypropyl.
Methylation na gaba tare da methyl chloride yana ƙara ƙungiyoyin methyl zuwa kashin bayan cellulose.
Ana iya sarrafa matakin musanya yayin haɗawa don samun kaddarorin da ake so.
4. Aikace-aikace:

An yi amfani da shi azaman mai ɗaure a cikin ƙirar kwamfutar hannu don haɗa abubuwan haɗin gwiwa tare.
Yana aiki azaman mai tarwatsewa don haɓaka rushewar allunan a cikin tsarin narkewar abinci.
Ci gaba da fitarwa:
Ana amfani da L-HPMC a cikin abubuwan da aka sarrafa-saki, yana ba da damar sakin maganin a hankali akan lokaci.
Shirye-shiryen Topical:
An samo shi a cikin creams, gels da man shafawa, yana ba da danko kuma yana inganta yaduwar tsarin.
B. Masana'antar Abinci:
Mai kauri:
Yana ƙara ɗanƙon abinci kuma yana inganta laushi da jin daɗin baki.
stabilizer:
Yana haɓaka kwanciyar hankali na emulsions da suspensions.
Samuwar fim:
Fina-finai masu cin abinci don marufi na abinci.
C. Masana'antar gine-gine:
Turmi da siminti:
An yi amfani da shi azaman wakili mai riƙe da ruwa a cikin kayan tushen siminti.
Inganta iya aiki da adhesion na turmi formulations.
D. Kayan shafawa:
Kayayyakin kula da mutum:
An samo shi a cikin creams, lotions da shampoos don taimakawa wajen inganta rubutu da kwanciyar hankali.
Ana amfani da shi azaman wakili mai yin fim a cikin kayan kwalliya.
5. Kulawa:
FDA Ta Amince:
An amince da L-HPMC gabaɗaya a matsayin aminci (GRAS) ta Hukumar Abinci da Magunguna ta Amurka (FDA).
Yarda da ƙa'idodin tsari yana da mahimmanci don amfani dashi a cikin magunguna da abinci.
6. Kalubale da abubuwan da ke gaba:
Halin Halitta:
Kodayake polymers na tushen cellulose gabaɗaya ana ɗaukar su a matsayin halitta, girman ɓarkewar abubuwan da aka gyara na cellulose yana buƙatar ƙarin bincike.
Dorewa:
Dorewa mai dorewa na albarkatun kasa da hanyoyin samar da muhalli sune wuraren ci gaba da mai da hankali.
7. Kammalawa:
Ƙananan maye gurbin hydroxypropyl methylcellulose yana nuna basirar gyare-gyaren sinadarai wajen yin amfani da kaddarorin polymers na halitta.Aikace-aikace iri-iri a cikin masana'antu daban-daban suna nuna mahimmancinsa a masana'antar zamani.Kamar yadda ci gaban fasaha da dorewa ke ɗaukar mataki na tsakiya, ci gaba da bincike da inganta L-HPMC da makamantansu na iya tsara makomar kimiyyar kayan aiki da ayyukan masana'antu.
