Hydroxypropylmethylcellulose (HPMC) ke polymer e entsoeng ka selulose e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa liindasteri tsa kaho, tsa meriana le tsa letsatsi le letsatsi. Ke motsoako o sebetsang ka bongata o nang le thepa e ikhethang e fanang ka melemo e mengata lihlahisoa tse fapaneng. Har'a mefuta e mengata ea HPMC, boemo ba metsi a batang hang-hang ke e 'ngoe ea tse hlokomelehang, haholo-holo tšimong ea lik'hemik'hale tsa letsatsi le letsatsi.
(1), tlhaloso le mokhoa oa tlhahiso
Pele re utloisisa litšobotsi tsa HPMC ea letsatsi le letsatsi ea metsi a batang ea lik'hemik'hale, a re ke re utloisise pele tlhaloso ea eona le ts'ebetso ea tlhahiso. HPMC ke non-ionic selulose ether, e leng fumanoa ka ho phekola tlhaho selulose (jwalo ka k'hothone linters kapa lehong pulp) ka alkali, 'me joale etherifying le propylene oxide le methyl chloride. Karabelo ena ea lik'hemik'hale e hlahisa phofo e tšoeu ho isa ho e tšoeu e qhibilihang ka metsing le lihlapolli tsa tlhaho. Mokhahlelo oa hang-hang oa metsi a batang oa HPMC o bua ka mofuta o itseng oa HPMC o bonolo ho qhibiliha metsing a batang, ho fapana le HPMC e tloaelehileng e hlokang metsi a chesang ho qhibiliha. Phetoho ena ea hang-hang ea metsi a batang e finyelloa ka ho khetha lisebelisoa tse tala, ho lokisa maemo a etherification, le ho laola kabo ea boholo ba likaroloana.
(2). Likarolo le melemo
Cosmetic grade metsi a batang hang-hang HPMC e na le thepa le melemo e mengata e etsang hore e be motsoako oa bohlokoa lihlahisoa tse ngata tsa tlhokomelo ea motho. Mona ke tse ling tsa likarolo tsa eona tse hlokomelehang:
1. Bokhoni bo phahameng ba ho boloka metsi: HPMC ke hydrophilic, ho bolelang hore e hohela le ho boloka metsi. K'hemik'hale ea letsatsi le letsatsi ea metsi a batang hang-hang HPMC e na le bokhoni bo phahameng ba ho boloka metsi, e leng molemo ho eketsa viscosity le botsitso ba sehlahisoa. Thepa ena e bohlokoa haholo ho lihlapa tse metsi, shampoo le lihlahisoa tsa ho hlatsoa 'mele.
2. Lintho tsa ho etsa lifilimi: HPMC e etsa filimi e bonaletsang le e tenyetsehang ha e omme letlalong kapa moriring. Filimi ena e sireletsa letlalo linthong tse ka ntle tse kang tšilafalo, mahlaseli a UV le lik'hemik'hale. E boetse e etsa hore moriri o shebahale o benya le boreleli. Lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale, thepa ea ho etsa filimi ea HPMC e atisa ho sebelisoa lihlahisoa tsa setaele sa moriri, litlolo tse sireletsang letsatsi, li-moisturizers, joalo-joalo.
3. Thickening le emulsifying thepa: HPMC ka thicken le emulsify liforomo, e bolelang hore e ka thusa ho tsitsisa oli le metsi lihlahisoa. Tšobotsi ena e bohlokoa haholo lihlahisoa tsa mofuta oa tranelate tse kang litlolo tsa 'mele, sefahleho sa sefahleho le tranelate ea mahlo.
4. E bonolo ebile e sa halefise: HPMC ke motsoako oa biocompatible, o se nang chefo o ke keng oa baka ho teneha kapa ho kula. E bonolo letlalong ntle le ho senya pH ea tlhaho kapa lipid barrier. Thepa ena e etsa hore e be motsoako o loketseng lihlahisoa tsa tlhokomelo ea masea, limaske tsa sefahleho le lihlahisoa tsa letlalo le bobebe.
5. Ho feto-fetoha ha maemo: HPMC e ka sebelisoa hammoho le lisebelisoa tse ling, tse kang li-surfactants, li-preservatives, monko o monate, joalo-joalo, ntle le ho ama ts'ebetso ea eona. E ka ikamahanya le mekhoa e fapaneng ho fana ka moisturizing, thobang, tlhoekiso le melemo e meng.
(3). Sebaka sa kopo
Letsatsi le leng le le leng la lik'hemik'hale tsa metsi a batang hang-hang HPMC e na le mefuta e mengata ea likopo indastering ea tlhokomelo ea botho. Tse ling tsa lihlahisoa tse atileng haholo tse e sebelisang ke:
1. Li-wipes tse metsi: HPMC e ka fana ka ho teteaneng, ho boloka metsi le thepa ea letlalo e hlokoang ke ho hlakola metsi. E ka etsa hore lihlaseli li ikutloe li le mongobo, li le bonolo ebile li tšoarella.
2. Shampoo le shaoara gel: HPMC ka eketsa viscosity le ho phophoma ha shampoo le gel ea shaoara, ho etsa hore ho be bonolo ho li sebelisa le ho hlatsoa. E boetse e na le phello ea boemo ba moriri le letlalo.
3. Lihlahisoa tsa moriri oa moriri: HPMC e etsa filimi e tenyetsehang ho pota-pota moriri, e thusang ho boloka sebōpeho le molumo oa eona. E boetse e sireletsa moriri ho senya mongobo le mocheso.
4. Setlolo se sireletsang letlalo letsatsing: HPMC e ka sebetsa joalo ka sehlahisoa se sireletsang letsatsi ho matlafatsa matla a ho sefa ha UV. E boetse e fana ka maikutlo a silika le a se nang mafura letlalong.
5. Mask: HPMC e ka fana ka gel, moisturizing le thepa ea ho etsa filimi e hlokoang ke mask. E thusa mask ho khomarela letlalo le ho fana ka metsoako e sebetsang.
(4). ha re phethela
Cosmetic grade metsi a batang hang-hang hydroxypropyl methylcellulose ke motsoako o sebetsang oa melemo o ntlafatsang boleng le ts'ebetso ea lihlahisoa tsa tlhokomelo ea motho. Bokhoni ba eona bo phahameng ba ho boloka metsi, thepa ea ho etsa filimi, ho teteka le ho etsa emulsifying thepa, bonolo le ho feto-fetoha ha maemo ho etsa hore e be motsoako oa bohlokoa lihlopheng tse ngata. Tšebeliso e atileng ea eona linthong tse hlapang metsi, li-shampoo le litlhatsoetso tsa 'mele, lihlahisoa tsa moriri, litlolo tse tlotsang letsatsi le limaske tsa sefahleho li bontša ho rarahana ha eona, molemo le katleho ea eona. Kaha bareki ba na le litlhoko tse phahameng bakeng sa katleho, polokeho le ts'ebetso ea lihlahisoa tsa tlhokomelo ea botho, letsatsi le leng le le leng la lik'hemik'hale tsa metsi a batang hang-hang HPMC e ka 'na ea phetha karolo ea bohlokoa ho feta indastering.
