Hydroxypropyl Methylcellulose (HPMC)ke motsoako oa polymer o qhibilihang ka metsi o nkiloeng ho selulose ea tlhaho 'me o sebelisoa haholo lihlahisoa tse fapaneng tsa tlhokomelo ea letlalo, litlolo le lihlahisoa tsa meriana. Joaloka selulose e fetotsoeng, ha e sebelisoe haholo indastering feela, empa e boetse e phetha likarolo tse ngata lihlahisoa tsa tlhokomelo ea letlalo.
1. Thickeners le Stabilizers
Hydroxypropyl methylcellulose ke setenya se sebetsang hantle se ka eketsang haholo ponahalo ea lihlahisoa tsa tlhokomelo ea letlalo le ho thusa sehlahisoa ho etsa sebopeho se loketseng. Hangata e eketsoa ho litlolo, litlolo, lihlahisoa tsa sefahleho le lihlahisoa tse ling ho e fa viscosity e itekanetseng, e seng bonolo feela ho e sebelisa, empa hape e ntlafatsa tšebeliso le matšeliso a sehlahisoa.
Ho phaella moo, phello e matla ea HPMC ka foromo e thusa ho tsitsisa sebopeho sa emulsion, ho thibela motsoako oa stratification kapa karohano ea oli ea metsi, le ho lelefatsa sethala sa bophelo ba sehlahisoa. Ka ho eketsa viscosity ka foromo, e etsa hore tšebelisano pakeng tsa karolo ea metsi le karolo ea oli e be e tsitsitseng haholoanyane, ka tsela eo e tiisa ho ts'oana le botsitso ba lihlahisoa tse kang lotions le litlolo.
2. Phello ea mongobo
Hydroxypropyl methylcellulose e na le hydration e ntle, 'me limolek'hule tsa eona li na le lihlopha tsa hydrophilic tse ka etsang likamano tsa hydrogen le limolek'hule tsa metsi ho thusa ho boloka mongobo. HPMC ha e na karolo e ntseng e eketseha ea lihlahisoa tsa tlhokomelo ea letlalo feela, empa hape e monya le ho notlela mongobo, e fana ka liphello tsa nako e telele tsa mongobo. Sena se thusa haholo-holo bakeng sa letlalo le omileng kapa ho omella ha nako ea selemo, ho boloka letlalo le le metsi.
Litlolong tse ling le litlolo tse nang le hydroxypropyl methylcellulose, phello ea tsona ea mongobo e ntlafatsoa le ho feta, e siea letlalo le ikutloa le le bonolo, le le boreleli ebile le sa omelle ebile le le thata.
3. Ntlafatsa maikutlo a letlalo le ho ama
Kaha sebopeho sa limolek'hule tsa HPMC se na le maemo a itseng a ho feto-fetoha ha maemo, se ka ntlafatsa haholo maikutlo a lihlahisoa tsa tlhokomelo ea letlalo, tsa etsa hore li be boreleli le ho ba bonolo haholoanyane. Nakong ea tšebeliso, hydroxypropyl methylcellulose e ka fana ka sehlahisoa se nang le silika, se bonolo, e le hore letlalo le se ke la ikutloa le le mafura kapa le khomarela ka mor'a kopo, empa le tla kenngoa ka potlako ho boloka phello e khathollang le e phutholohileng.
Ntlafatso ena ea sebopeho ke ntho e amehang haholo ho bareki, haholo-holo ho basebelisi ba nang le letlalo le nang le kutlo kapa mafura, moo maikutlo nakong ea ts'ebeliso e leng bohlokoa haholo.
4. Laola ho phalla ha metsi le ho ata ha foromo
Phello e koenyang eaHPMCha e etse feela sehlahisoa se teteaneng, empa hape se laola ho phalla ha sehlahisoa, ho etsa hore se tšoanelehe bakeng sa kopo. Haholo-holo bakeng sa lihlahisoa tse ling tsa lotion le gel, tšebeliso ea hydroxypropyl methylcellulose e ka ntlafatsa ts'ebetso e ts'oanang, e lumella sehlahisoa hore se hasane hantle letlalong ntle le ho rotha kapa ho senya.
Ka litlolo tse ling tsa mahlo kapa lihlahisoa tsa tlhokomelo ea lihlooho, ho eketsoa ha hydroxypropyl methylcellulose ho ka ntlafatsa ka katleho ho boreleli ha kopo, ho lumella sehlahisoa hore se sebelisoe ka mokhoa o ts'oanang libakeng tse thata tsa letlalo ntle le ho baka khathatso.
5. Joaloka moemeli ea emisang
Hangata Hydroxypropyl methylcellulose e sebelisoa e le ntho e emisang lihlahisoa tse ling tsa tlhokomelo ea letlalo, haholo-holo tse nang le metsoako e sebetsang kapa metsoako ea granular. E ka thibela ka mokhoa o atlehileng ho na kapa ho arohana ha metsoako e tiileng (joalo ka likaroloana tsa liminerale, lihlahisoa tsa limela, joalo-joalo), ho netefatsa hore metsoako eohle e entsoeng ka foromo e arotsoe ka ho lekana, 'me e qoba ho ama ts'ebetso le ponahalo ea sehlahisoa ka lebaka la ho na ha motsoako kapa layering.
Mohlala, ho limaske tse ling tsa sefahleho tse nang le likaroloana tsa scrub kapa li-extracts tsa semela, HPMC e ka thusa ho boloka kabo e lekanang ea likaroloana, ka hona e ntlafatsa ts'ebetso ea sehlahisoa.
6. E bonolo ebile e sa khopise
Joaloka motsoako o ntšitsoeng ho cellulose ea tlhaho, hydroxypropyl methylcellulose ka boeona e na le biocompatibility e ntle le hypoallergenicity, kahoo e loketse mefuta eohle ea letlalo, haholo-holo letlalo le nang le bothata. Bonolo ba eona bo etsa hore e sireletsehe ho sebelisoa lihlahisoa tse sa tšoaneng tsa tlhokomelo ea letlalo ntle le ho baka ho teneha kapa ho se thabise letlalong.
Tšobotsi ena e etsa hore HPMC e be motsoako o ratoang bakeng sa lihlahisoa tse ngata ha ho etsoa lihlahisoa bakeng sa letlalo le bonolo, tlhokomelo ea letlalo la lesea, le lihlahisoa tse sa kenyelletsoeng.
7. Ntlafatsa mesebetsi ea antioxidant le e khahlanong le tšilafalo
Liphuputso tse ling li bontšitse hore mohaho oa limolek'hule oa hydroxypropyl methylcellulose, motsoako oa tlhaho oa cellulose, o ka fana ka tšireletso ea antioxidant le e khahlanong le tšilafalo ho isa tekanyong e itseng. Ka lihlahisoa tsa tlhokomelo ea letlalo, e ka sebelisoa hammoho le lisebelisoa tse ling tsa antioxidant (tse kang vithamine C, vithamine E, joalo-joalo) ho thusa ho tlosa li-radicals tsa mahala le ho liehisa mokhoa oa ho tsofala ha letlalo. Ho feta moo, sebopeho sa hydrophilic sa HPMC se ka thusa ho sireletsa letlalo ho tsoa linthong tse silafatsang moeeng.
Hydroxypropyl methylcellulosee bapala karolo e ngata lihlahisoa tsa tlhokomelo ea letlalo. E ke ke ea sebetsa feela e le motenya le stabilizer ho ntlafatsa sebopeho le boikutlo ba sehlahisoa, empa hape e na le mesebetsi ea bohlokoa e kang ho nosetsa, ho ntlafatsa letlalo la letlalo, le ho laola metsi. E le motsoako o bonolo le o sebetsang hantle, o ka ntlafatsa katleho ea lihlahisoa tsa tlhokomelo ea letlalo le boiphihlelo ba bareki. E sebelisoa haholo lihlahisoa tse fapaneng tsa tlhokomelo ea letlalo joalo ka litlolo tsa sefahleho, litlolo, lihloekisi tsa sefahleho le limaske tsa sefahleho. Ha tlhokahalo ea lisebelisoa tsa tlhaho le lihlahisoa tse bonolo tsa tlhokomelo ea letlalo li ntse li eketseha, hydroxypropyl methylcellulose e tla tsoela pele ho phetha karolo ea bohlokoa ho nts'etsopele ea sehlahisoa sa tlhokomelo ea letlalo nakong e tlang.
