HEC phello ho viscosity le botsitso ba lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale

Hydroxyethyl cellulose (HEC) ke polymer e sebelisoang haholo e sa sebeliseng metsi, e qhibilihang ka metsing e tsoang ho selulose. Tšebeliso ea eona ea mantlha lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi e bakoa ke bokhoni ba eona ba ho fetola rheology, ho tsitsisa metsoako, le ho ntlafatsa sebopeho sa lihlahisoa.

Thepa le Mechanism ea HEC

HEC e khetholloa ka thepa ea eona e teteaneng, e emisang, e tlamang le e emulsifying. E bontša pseudoplasticity e phahameng, ho bolelang hore viscosity ea eona e fokotseha tlas'a khatello ea ho kuta empa e khutlela boemong ba eona ba pele hang ha khatello e tlosoa. Thepa ena e na le molemo mekhoeng e fapa-fapaneng kaha e lumella lihlahisoa hore li lule li le teteaneng ebile li tsitsitse holim'a sethala empa ho le bonolo ho li sebelisa kapa ho hasana ha li sebelisoa.

Mokhoa oa ts'ebetso ea HEC o itšetlehile ka sebopeho sa eona sa limolek'hule. Liketane tsa polymer li etsa marang-rang a ka tšoarang metsi le likarolo tse ling, a etsa matrix a kang gel. Sebopeho sena sa marang-rang se itšetlehile ka tekanyo ea ho nkela sebaka le boima ba molek'hule ea HEC, e ka fetoloang ho finyella viscosity e lakatsehang le botsitso ha ho etsoa.

Tšusumetso ho Viscosity

Thickening Effect

HEC e susumetsa haholo viscosity ea lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi ka ho tiisa karolo ea metsi. Ka lihlahisoa tsa tlhokomelo ea botho tse kang li-shampoo le lotions, HEC e eketsa viscosity, e lebisang ho sebopeho se ruileng le pono e ntlafetseng ea bareki. Kotsi ena e finyelloa ka hydration ea likaroloana tsa HEC, moo limolek'hule tsa metsi li kopanang le mokokotlo oa selulose, ho etsa hore polymer e ruruhe ebe e etsa tharollo ea viscous.

Khatiso ea HEC ha e etsoa ke ea bohlokoa bakeng sa ho finyella viscosity e lakatsehang. Maemong a tlase, HEC e eketsa haholo viscosity ea karolo ea metsi ntle le ho ama thepa ea phallo haholo. Libakeng tse phahameng, HEC e etsa mohaho o kang oa gel, o fana ka viscosity e tsitsitseng le e tsitsitseng. Ka mohlala, li-shampoo, likhahla tsa HEC ho tloha ho 0.2% ho ea ho 0.5% li ka fana ka viscosity e lekaneng bakeng sa ts'ebetso e boreleli, ha likhahla tse phahameng li ka sebelisoa bakeng sa li-gel kapa litlolo tse teteaneng.

Boitšoaro ba ho Shear-Thinning

Sebopeho sa pseudoplastic sa HEC se lumella lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi hore li bontše boitšoaro ba ho kuta. Sena se bolela hore tlas'a ketso ea mechine ea ho tšela, ho pompa, kapa ho hasana, viscosity e fokotseha, ho etsa hore sehlahisoa se be bonolo ho sebetsana le ho se sebelisa. Hang ha matla a ho kuta a tlosoa, viscosity e khutlela sebakeng sa eona sa pele, ho netefatsa hore sehlahisoa se lula se tsitsitse ka har'a setshelo.

Ka mohlala, ka sesepa sa metsi, HEC e thusa ho finyella tekano pakeng tsa sehlahisoa se tsitsitseng, se teteaneng ka botlolong le sesepa sa mokelikeli, se hasang habonolo ha se fanoa. Thepa ena e bohlokoa ka ho khetheha mekhoeng eo ho leng bonolo ho e sebelisa, joalo ka li-lotions le li-gels tsa moriri.

Tšusumetso ho Botsitso

Ho emisoa le ho Emulsification

HEC e ntlafatsa botsitso ba lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi ka ho sebetsa e le moemeli oa ho emisa le ho tsitsisa. E thibela ho arohana ha likaroloana tse tiileng le ho kopana ha marotholi a oli ka li-emulsions, kahoo ho boloka sehlahisoa sa homogeneous ka nako. Sena se bohlokoa haholo mekhoeng e nang le li-insoluble actives, pigments, kapa suspended particles .

Li-lotions le litlolo, HEC e tsitsisa li-emulsions ka ho eketsa viscosity ea mohato o tsoelang pele, kahoo e fokotsa ho tsamaea ha marotholi le likaroloana tse qhalakaneng. Mokhoa ona oa ho tsitsisa o bohlokoa bakeng sa ho boloka botsitso le katleho ea sehlahisoa nakong eohle ea bophelo ba sona. Ka mohlala, litlolong tse sireletsang letsatsi, HEC e thusa ho boloka lihloela tsa UV li ajoa ka mokhoa o tšoanang, ho netefatsa tšireletso e tsitsitseng khahlanong le mahlaseli a kotsi .

Ho Boloka Mongobo le Ho Etsa Lifilimi

HEC e boetse e kenya letsoho ho tsitsang ha metsoako ka ho ntlafatsa ho boloka mongobo le ho etsa filimi e sireletsang letlalong kapa moriri. Lihlahisoa tsa tlhokomelo ea moriri, thepa ena ea ho etsa filimi e thusa ho lokisa le ho boloka moriri ka ho tšoara mongobo le ho fana ka thibelo khahlanong le maemo a tikoloho .

Ka lihlahisoa tsa skincare, HEC e ntlafatsa ts'ebetso ea sehlahisoa ka ho fokotsa tahlehelo ea metsi letlalong, e fana ka phello e tšoarellang ea nako e telele ea hydrating. Tšobotsi ena e molemo ho lihlahisoa tse kang li-moisturizer le limaske tsa sefahleho, moo ho boloka metsi a letlalo e leng mosebetsi oa bohlokoa.

Lihlahisoa tsa Tlhokomelo ea Motho

Ka mekhoa ea tlhokomelo ea botho, HEC e sebelisoa haholo bakeng sa thepa ea eona e teteaneng le e tsitsitseng. Ka li-shampoo le li-conditioner, e fana ka viscosity e lakatsehang, e matlafatsa botsitso ba foam, 'me e ntlafatsa sebopeho, e leng se lebisang ho phihlelo e ntle ea kutlo bakeng sa mosebedisi.

Ka lihlahisoa tsa tlhokomelo ea letlalo tse kang litlolo, lotions, le li-gel, HEC e sebetsa e le motenya le ho tsitsisa, e tlatsetsang boikutlo bo boreleli le bo mabothobotho ba sehlahisoa. E boetse e thusa kabong e lekanang ea metsoako e sebetsang, ho ntlafatsa katleho ea sehlahisoa .

Lihlahisoa tsa Malapeng

Ka lihlahisoa tsa ho hloekisa malapeng, HEC e phetha karolo ea ho fetola viscosity le ho tsitsisa ho emisoa. Ka li-detergents tsa metsi le lisebelisoa tsa ho hlatsoa lijana, HEC e tiisa hore sehlahisoa se lula se le bonolo ho fana ka sona ha se ntse se boloka viscosity e lekaneng ea ho khomarela holimo, ho fana ka ts'ebetso e sebetsang ea ho hloekisa .

Ho li-fresheners tsa moea le li-softeners tsa masela, HEC e thusa ho boloka ho emisoa ho tšoanang ha monko o monate le likarolo tse sebetsang, ho netefatsa ts'ebetso e tsitsitseng le phihlelo e monate ea mosebedisi.

Hydroxyethyl cellulose (HEC) ke karolo e sebetsang ka mokhoa o fapaneng le ea bohlokoa tlhahisong ea lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale. Tšusumetso ea eona ho viscosity le botsitso e etsa hore e be ea bohlokoa ho theheng lihlahisoa tse fihlelang litebello tsa bareki bakeng sa sebopeho, ts'ebetso le ts'ebeliso. Ka ho ntlafatsa viscosity, ho netefatsa botsitso ba sehlahisoa, le ho ntlafatsa thepa ea kopo, HEC e tlatsetsa haholo katlehong le boipiletso ba bareki ba mefuta e mengata ea tlhokomelo ea botho le lihlahisoa tsa malapa. Ha tlhokahalo ea lihlahisoa tsa boleng bo phahameng, tse tsitsitseng, le tse sebelisoang habonolo li ntse li hōla, karolo ea HEC ho nts'etsopele ea lihlahisoa e ka 'na ea eketseha, e fana ka menyetla e mecha ea ho nchafatsa lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale.
