Hydroxypropyl Methylcellulose (HPMC) ke motsoako oa polymer o qhibilihang ka metsi o fumanoang ka ho fetola lik'hemik'hale tsa cellulose ea tlhaho. E sebelisoa haholo ho litlolo, meriana, thepa ea mohaho le lihlahisoa tsa ho hloekisa. Lihloekising, KimaCell®HPMC e bapala karolo ea bohlokoa joalo ka setei, se tsitsisa le ho etsa lifilimi.
1. Lintho tsa motheo tsa HPMC
HPMC ke phofo e tšoeu ho isa ho e tšoeu e sa nkhang hamonate e nang le metsi a monate le ho senyeha ha lintho. Sebopeho sa eona sa limolek'hule se na le lihlopha tsa hydrophilic tse kang methyl (-OCH₃) le hydroxypropyl (-OCH₂CHOHCH₃), kahoo e na le hydrophilicity e matla le solubility e ntle. Boima ba limolek'hule tsa HPMC, tekanyo ea ho fetola hydroxypropyl le methyl, le karolo ea bona e lekanyelitsoeng e khetholla ho qhibiliha ha eona, matla a ho teteaneng le botsitso. Ka hona, ts'ebetso ea HPMC e ka fetoloa ho latela litlhoko tse ikhethileng ho ikamahanya le maemo a fapaneng a ts'ebeliso.
2. Karolo ea HPMC ho li-detergents
Ka li-detergents, HPMC e atisa ho sebelisoa e le sekontiri le botsitso, 'me haholo-holo e ama ts'ebetso ea lihlahisoa ka litsela tse latelang:
2.1 Phello e teteaneng
HPMC na le matla thickening thepa le ka haholo eketsa viscosity ea detergents, ho ba fa thepa molemo rheological. Li-detergent tse teteaneng ha li thuse feela ho fokotsa ho rotha, empa hape li eketsa botsitso le ho tšoarella ha foam. Ka li-detergents tsa metsi, HPMC e atisa ho sebelisoa ho fetola metsi a sehlahisoa, ho etsa hore sesepa se be bonolo le ho se sebelisa habonolo nakong ea tšebeliso.
2.2 Foam e tsitsitseng
HPMC e boetse e na le karolo ea ho tsitsisa foam ho li-detergents. E eketsa viscosity ea mokelikeli mme e fokotsa lebelo la ho phatloha ha foam, ka hona e eketsa nako e telele ea foam. Ho feta moo, HPMC e ka fokotsa boholo ba foam, ea etsa hore foam e be e ts'oanang le ho tiea. Tšobotsi ena e bohlokoa ka ho khetheha ho li-detergent tse ling tse hlokang liphello tsa foam (tse kang shampoo, gel ea ho hlatsoa, joalo-joalo).
2.3 Ho ntlafatsa phallo ea li-surfactants
Sebopeho sa limolek'hule tsa HPMC se e nolofalletsa ho sebelisana le limolek'hule tsa surfactant, ho ntlafatsa ho senyeha le ho qhibiliha ha li-surfactants, haholo-holo mocheso o tlase kapa libakeng tse thata tsa metsi. Ka phello ea synergistic le li-surfactants, HPMC e ka ntlafatsa ts'ebetso ea ho hloekisa ea li-detergent ka katleho.
2.4 Joalo ka stabilizer ea ho emisoa
Litsing tse ling tse hlokang ho emisa likaroloana tse sa qhibiliheng (joalo ka phofo e hlatsoang, sefahleho sa sefahleho, joalo-joalo), KimaCell®HPMC e ka sebelisoa e le stabilizer ea ho emisa ho thusa ho boloka ho hasana ha likaroloana le ho thibela ho putlama ha likaroloana, ka hona ho ntlafatsa boleng le boleng. sebelisa phello ea sehlahisoa.
3. Phello ea HPMC holim'a botsitso ba li-detergents
3.1 Ho eketsa botsitso ba 'mele oa foromo
HPMC e ka ntlafatsa botsitso ba 'mele oa sehlahisoa ka ho lokisa viscosity ea sesepa. Sesepa se teteaneng se hlophisitsoe haholoanyane 'me se ka thibela ho hlaha ha liketsahalo tse sa tsitsang tse kang karohano ea mekhahlelo, pula le gelation. Ka li-detergents tsa mokelikeli, HPMC e le motenya e ka fokotsa ka katleho ketsahalo ea ho arohana ha karolo le ho netefatsa botsitso ba nako e telele ea sehlahisoa nakong ea polokelo.
3.2 Ho ntlafatsa botsitso ba pH
Boleng ba pH ba li-detergents ke ntlha ea bohlokoa e amang ts'ebetso ea bona le botsitso. HPMC e ka thibela ho feto-fetoha ha pH ho isa bohōleng bo itseng 'me ea thibela litlolo hore li se ke tsa bola kapa tsa senyeha tikolohong ea asiti le alkaline. Ka ho lokisa mofuta le mahloriso a HPMC, botsitso ba li-detergents tlas'a maemo a fapaneng a pH bo ka ntlafatsoa.
3.3 Matlafatso ea ho hanyetsa mocheso
Liphetolelo tse ling tse fetotsoeng tsa HPMC li na le khanyetso e matla ea mocheso o phahameng 'me li ka boloka botsitso ba lisebelisoa tsa ho hlatsoa lithempereichara tse phahameng. Sena se etsa hore HPMC e sebelisoe haholo libakeng tse phahameng tsa mocheso. Ka mohlala, ha litlolo tsa ho hlatsoetsa liaparo le li-shampoo li sebelisoa ka mocheso o phahameng, li ntse li ka boloka botsitso ba tsona 'meleng le liphello tsa ho hloekisa.
3.4 Matlafatso ea mamello ea metsi a thata
Likarolo tse kang calcium le magnesium ion metsing a thata li tla ama botsitso ba li-detergents, e leng se tla fella ka ho fokotseha ha ts'ebetso ea sesepa. HPMC e ka ntlafatsa botsitso ba li-detergents libakeng tse thata tsa metsi ho isa tekanyong e itseng le ho fokotsa ho hlōleha ha li-surfactants ka ho etsa li-complexes tse nang le li-ion metsing a thata.
3.5 Tšusumetso holim'a botsitso ba foam
Le hoja HPMC e ka ntlafatsa ka katleho botsitso ba foam ea li-detergents, mahloriso a eona a phahame haholo 'me a ka boela a etsa hore foam e be viscous haholo, kahoo e ama phello ea ho hlatsoa. Ka hona, ke habohlokoa ho fetola ka mokhoa o utloahalang mahloriso a HPMC ho botsitso ba foam.
4. Ntlafatso ea tlhahiso ea sesepa ke HPMC
4.1 Ho khetha mofuta o nepahetseng oa HPMC
Mefuta e fapaneng ea KimaCell®HPMC (joalo ka likhato tse fapaneng tsa phapanyetso, boima ba molek'hule, joalo-joalo) e na le litlamorao tse fapaneng ho lihlapa. Ka hona, ha ho etsoa moralo, hoa hlokahala ho khetha HPMC e nepahetseng ho latela litlhoko tse khethehileng tsa tšebeliso. Ka mohlala, boima bo phahameng ba limolek'hule HPMC ka kakaretso bo na le phello e ntlafetseng, ha boima ba limolek'hule bo tlaase HPMC bo ka fana ka botsitso bo betere ba foam.
4.2 Ho fetola mohopolo oa HPMC
Khatiso ea HPMC e na le phello e kholo ts'ebetsong ea sesepa. Ho fokotseha haholo ho ka 'na ha se ke ha e-ba le phello e matla ea eona ka ho feletseng, ha ho tsepamisa mohopolo ho ka etsa hore foam e be e teteaneng haholo' me e ame phello ea ho hloekisa. Ka hona, phetoho e utloahalang ea mahloriso a HPMC ke senotlolo sa ho netefatsa botsitso ba ts'ebetso ea sesepa.
4.3 Tšusumetso ea Synergistic le li-additives tse ling
HPMC e atisa ho sebelisoa hammoho le thickeners tse ling, stabilizers le surfactants. Ka mohlala, ho kopantsoe le hydrated silicates, ammonium chloride le lintho tse ling, e ka ntlafatsa ts'ebetso ea kakaretso ea sesepa. Tsamaisong ena ea motsoako, HPMC e bapala karolo ea bohlokoa 'me e ka matlafatsa botsitso le phello ea ho hloekisa ea foromo.
HPMC e ka ntlafatsa haholo botsitso ba 'mele le lik'hemik'hale tsa li-detergents e le motenya, stabilizer le foam stabilizer ho li-detergents. Ka khetho e nepahetseng le karohano, HPMC e ke ke ea ntlafatsa rheology feela, botsitso ba foam le phello ea ho hloekisa ea li-detergents, empa hape e ntlafatsa ho hanyetsa mocheso le ho ikamahanya le maemo a thata a metsi. Ka hona, KimaCell®HPMC e na le menyetla e batsi ea ts'ebeliso le menyetla ea nts'etsopele, joalo ka motsoako oa bohlokoa mekhoeng ea litlolo. Lipatlisisong tsa nako e tlang, mokhoa oa ho ntlafatsa ts'ebeliso ea HPMC le ho ntlafatsa botsitso le ts'ebetso ea eona ho li-detergent e ntse e le sehlooho se lokeloang ke ho hlahlojoa ka botebo.
