Hydroxypylththththththylcelllose (hpmc)naHydroxyethythythythyth Cellulose (HEC)bụ ihe abụọ na-ejikarị cellulose. A na-eji ha arụ ọrụ n'ọtụtụ ebe, ọgwụ, ihe ịchọ mma, nri na ụlọ ọrụ ndị ọzọ n'ihi ihe ndị ha pụrụ iche na ojiji. Ọ bụ ezie na ha bụ ihe a na-enweta mmiri polmer site na selmelose, enwere ọdịiche dị n'etiti ha abụọ, arụmọrụ na ngwa.
1. Ọdịiche na usoro kemịkalụ
Hpmc (hydroxypylthylthylcelllose)
Ọ bụ nke na-abụghị nke ionic cellulose na-enweta site na imeghachi na methanol na proplene oxide mgbe alkalization. Ọdịmma ya nwere metoxy (-OCKy (-OCKE) na hydroxypropoxy (-ch2chohch3) ndị nnọchi anya. Enwere ike ịgbanwe ogo nke HPMC dị ka ojiji dị iche iche.
Hec (hydroxyethyth Cellulose)
Ọ bụ ngwaahịa a na-enweta site na mmeghachi omume nke cellulose na ethylene oxide mgbe alkalization, ihe owuwu ya nwere hydroxyethyl (-ch2CH9OH) ndị hibere. HEC bụ mmiri na-abụghị nke iic-soluble ewer, a pụkwara ịgbanwe ogo ya dịka mkpa akọwapụtara.
2. Ọ dị iche iche
Soluuru
Kimacell®hpmc nwere ike igba ngwa ngwa na mmiri oyi iji mejupụta ntụze ma ọ bụ mmiri mmiri ara ehi, nke na-eguzogide oke okpomọkụ. Ọ nwere ezigbo nnu na alkali iguzogide ma nwee ike ịdị n 'sọsọ plọ (3-11).
Kimacelly® bụ na-sodible na mmiri oyi, mana ọnụ ọgụgụ ụkọ adịghị nwayọ, na nkwụsi ike na elu okpomọkụ ma ọ bụ ebe obibi dị elu dị elu. Na mgbakwunye, HEC anaghị enwe mmetụta na-enweghị atụ na pH ma enwere ike iji ya na plọ nke 2-12.
Mmetụta Dị Mmiri
HPMC nwere mmetụta siri ike ma nwee ezigbo ndọtị mmiri na nkwụsi ike.
HEC nwekwara ezigbo mmetụta nke na-atọ ụtọ, mana ọnụego ya dị ukwuu site na ọnụego oke osisi ma na-egosi ọchịcha.
Elu ọrụ
HPMC nwere ụfọdụ ọrụ dị elu ma nwee ike ịmepụta ezigbo emulsification na mmetụta ihe nkiri.
HEC nwere ọrụ dị ala na enweghị ihe emuls emulsial, mana nwere ezigbo usoro ihe nkiri.
3. Ọdịiche ngwa
Uche owuwu
A na-eji HPMC mee ihe n'ọtụtụ ụlọ, dịka ntụ ntụ ntụ, ngwa agha, ngwa agha na-eme ka njigide mmiri, na-eguzogide na arụmọrụ.
A na-ejikarị hec na agba mbubreyo na agba mmiri dị ka nke na-agba mmiri ma sie ike iji bulie viscosit na Njirimara Anti-Sage.
Ugbo ala
A na-eji HPMC na-ejikarị ihe mkpuchi, na-achịkwa onye ọrụ na capsule shei maka mbadamba ọgwụ.
A naghị eji hec arụ ọrụ na mpaghara ọgwụ ma n'oge ụfọdụ dị ka onye na-eme nke ọma maka nkwụsị ọgwụ.
Ngwaahịa na ngwaahịa kemile kemịkalụ kwa ụbọchị
A na-eji HPMC mee ihe na ngwaahịa nlekọta anụ ahụ na ihe ndị na-egbochi iji nye ngwaahịa ka mma moisturizizizi na nkwụsi ike emunsizi.
A na-eji hec n'ọtụtụ ebe na shampoo, gel, wdg iji nye nsonaazụ na-enweghị atụ na nkwusioru.

A na-eji HPMC mee ihe dị ka nke na-adịkarị, emulsifier na mmachi nri ma na-ejikwa jelii, sauces na ngwongwo.
A na-eji hec arụ ọrụ na ụlọ ọrụ nri, mana enwere ike iji ya dị ka onye na-anụ ọkụ na ụfọdụ ihe ọveraụ na confress.
4. Ọnụahịa na ahịa
HPMC na-adịkarị ọnụ karịa hec n'ihi usoro ya siri ike na oke ojiji dịgasị iche iche. Usoro mmepụta HEC dịtụ mfe ma na-ejikarị maka ndị na-eme mkpọtụ ma sie ike, yabụ ọnụahịa dị ala.
Hydroxypyl Methylcellose (HPMC) na hydroxyethyth Cellulose (HEC) nke ọ bụla nwere ihe nhazi nke ha na akụrụngwa ha. Kimacell®hpmc dị mma maka ihe nkiri na arụmọrụ chọrọ, nwere njigide mmiri dị mma na akụrụngwa akụrụngwa, ma nwee ọtụtụ ngwa. N'aka nke ọzọ, a na-ejikarị ya na mkpuchi, kemịkalụ nke na oge ndị ọzọ chọrọ ime ka ọ dị ala na nkwusioru ya dị ala. Na nhọrọ n'ezie, a ga-echebara echiche zuru oke na ego akụ na ụba.
