Selelekela ho HPMC
Hydroxypropyl methylcellulose (HPMC), eo hape e tsejoang e le hypromellose, ke polymer e entsoeng ka semi-synthetic e nkiloeng ho selulose. E sebelisoa haholo liindastering tse fapaneng, ho kenyelletsa le tsa meriana, lijo, le tlhokomelo ea motho ka mong, ka lebaka la thepa ea eona e fapaneng. Ka lihlahisoa tsa tlhokomelo ea botho, HPMC e sebeletsa mesebetsi e mengata e kang ho teteaneng, ho emulsifying, ho etsa lifilimi, le ho tsitsisa, ho matlafatsa ts'ebetso le phihlelo ea mosebedisi ea lihlahisoa tsena.
Thepa ea HPMC
HPMC e na le lisebelisoa tse 'maloa tsa bohlokoa tse e etsang hore e be ea bohlokoa mekhoeng ea tlhokomelo ea motho ka mong:
Ho qhibiliha ha Metsi: HPMC e qhibiliha habonolo metsing a batang, e etsa litharollo tse hlakileng, tse hlakileng.
Thermal Gelation: E bonts'a gelation e fetohang ha e futhumatsa, e leng molemo ho laola viscosity le sebopeho sa lihlahisoa.
Bokhoni ba ho Etsa Lifilimi: HPMC e ka theha lifilimi tse matla, tse tenyetsehang tse se nang tacky le tse pepeneneng.
pH botsitso: E lula e tsitsitse ho pholletsa le mefuta e mengata ea pH, e netefatsa ts'ebetso e tsitsitseng mekhoeng e fapaneng.
Biocompatibility: Kaha e nkiloe ho selulose, e sebetsa hantle ebile ha e na chefo, e etsa hore e bolokehe bakeng sa tšebeliso ea lihlahisoa tsa tlhokomelo ea motho.
Tšebeliso ea HPMC ho Lihlahisoa tsa Tlhokomelo ea Motho
1. Thickening Agent
HPMC e sebediswa ka tlwaelo e le motenya dihlahiswa tsa tlhokomelo ya botho tse kang shampoos, conditioners, lotions, le litlolo. Bokhoni ba eona ba ho eketsa viscosity bo thusa ho ntlafatsa sebopeho le ho ata ha lihlahisoa tsena, ho fana ka maikutlo a majabajaba nakong ea kopo. Ka mohlala:
Li-Shampoos le Li-conditioner: HPMC e thusa ho theha lesela le monate, le monate le ho ntlafatsa viscosity, ho etsa hore sehlahisoa se be bonolo ho se sebelisa le ho ajoa ka moriri.
Litlolo le Litlolo: Ka litlolo le litlolo, li matlafatsa botenya 'me li fana ka sebopeho se boreleli, se se nang mafura, ho ntlafatsa phihlelo ea kutlo ka kakaretso.
2. Emulsifying Agent
Mekhahlelong moo likarolo tsa oli le metsi li hlokang ho kopanngoa, HPMC e sebetsa joalo ka emulsifying agent. E thusa ho tsitsisa li-emulsions ka ho fokotsa tsitsipano ea holim'a metsi le ho thibela ho arohana ha mekhahlelo. Sena se bohlokoa haholo lihlahisoa tse kang:
Moisturizers le Sunscreens: HPMC e netefatsa kabo e tšoanang ea metsoako e sebetsang, e matlafatsang katleho ea sehlahisoa le botsitso.
Metheo le Litlolo tsa BB: E thusa ho boloka sebopeho le ponahalo e tsitsitseng, ho thibela karolo ea oli ho arohana le karolo ea metsi.
3. Moemeli oa ho Etsa Lifilimi
Bokhoni ba HPMC ba ho etsa lifilimi bo sebelisoa lihlahisoa tse fapaneng tsa tlhokomelo ea motho, ho fana ka melemo e joalo ka ho boloka mongobo, ts'ireletso le ts'ebetso e ntlafalitsoeng ea sehlahisoa. Mohlala:
Li-gels tsa Moriri le Lihlahisoa tsa Setaele: Thepa ea ho etsa filimi ea HPMC e thusa ho ts'oara mekhoa ea moriri sebakeng sa eona, ho fana ka ho ts'oara ho fetohang, ho se nang letheba.
Li-mask tsa Sefahleho le Likhapetla: Li-mask tsa peel-off, HPMC e etsa filimi e momahaneng e ka tlosoang habonolo, e nkang litšila le lisele tsa letlalo tse shoeleng.
4. Stabilizer
HPMC e sebetsa joalo ka stabilizer mekhoeng e nang le metsoako e sebetsang e ka bang hlokolosi ho mabaka a tikoloho joalo ka liphetoho tsa khanya, oksijene, kapa pH. Ka ho tsitsisa metsoako ena, HPMC e netefatsa bophelo bo bolelele le katleho ea sehlahisoa. Mehlala e kenyelletsa:
Litlolo tse thibelang botsofali: HPMC e thusa ho boloka botsitso ba li-antioxidants le lisebelisoa tse ling tse sebetsang.
Whitening Products: E tsitsisa ho hlophisoa ho thibela ho senyeha ha metsoako e sa utloisiseng khanya.
5. Moemeli oa Phallo e Laolehileng
Lihlahisoa tse ling tsa tlhokomelo ea botho, tokollo e laoloang ea metsoako e sebetsang e lakatseha bakeng sa katleho ea nako e telele. HPMC e ka sebelisoa ho fihlela tokollo ena e laoloang, haholo lihlahisoa tse kang:
Anti-dandruff Shampoos: HPMC e ka fetola ho lokolloa ha metsoako e sebetsang joalo ka zinki pyrithione, ho netefatsa hore ho nka nako e telele ho thibela dandruff.
Li-Mask tsa Bosiu: E lumella ho lokolloa butle ha metsoako ea hydrating le e matlafatsang bosiu bohle.
Melemo ea ho Sebelisa HPMC ho Lihlahisoa tsa Tlhokomelo ea Motho
Mefuta-futa: Thepa ea HPMC e nang le mesebetsi e mengata e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea lits'ebetso.
Polokeho: E le motsoako o se nang chefo, o lumellanang le biocompatible, HPMC e bolokehile hore e ka sebelisoa letlalong le moriring.
Botsitso: E ntlafatsa botsitso ba libopeho, ho ntlafatsa sethala sa bophelo le ts'ebetso ea lihlahisoa tsa tlhokomelo ea botho.
Boiphihlelo ba Bareki: HPMC e ntlafatsa litšobotsi tsa kutlo tsa lihlahisoa, e fana ka boiphihlelo bo monate ba ts'ebeliso.
Mathata le Litlhaloso
Leha HPMC e fana ka melemo e mengata, baetsi ba lihlahisoa ba tlameha ho nahana ka mathata a itseng:
Tšebelisano: HPMC e tlameha ho lumellana le metsoako e meng ea tlhahiso ho qoba litaba tse kang karohano ea mekhahlelo kapa ho fokotsa ts'ebetso.
Maikutlo: Khokahano ea HPMC e hloka ho ntlafatsoa ho fihlela viscosity e lakatsehang le ts'ebetso ntle le ho senya botsitso ba sehlahisoa kapa litšobotsi tsa kutlo.
Litšenyehelo: Le hoja e baballa litšenyehelo ha e bapisoa le mekhoa e meng, baetsi ba foromo ba tlameha ho leka-lekanya litšenyehelo le litlhoko tsa ts'ebetso.
HPMC ke motsoako oa bohlokoa lihlahisoa tsa tlhokomelo ea botho, tse tlatsetsang katlehong, botsitso, le phihlelo ea mosebedisi ea mefuta e mengata ea libopeho. Lintho tsa eona tse nang le mesebetsi e mengata li e lumella hore e sebetse e le moemeli o teteaneng, emulsifier, filimi-former, stabilizer, le moemeli oa tokollo o laoloang. Ha indasteri ea tlhokomelo ea botho e ntse e tsoela pele ho iqapela, karolo ea HPMC e kanna ea hola, e tsamaisoa ke maemo a eona a fapaneng le a polokeho. Baqapi ba tlameha ho nahana ka litlhoko tse ikhethileng tsa lihlahisoa tsa bona le bareki ho kenyelletsa HPMC ka nepo, ho netefatsa ts'ebetso e nepahetseng le khotsofalo.
