IHydroxypropylmethylcellulose (HPMC) iyi-polymer etholakala ku-cellulose esetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi izimboni zokwakha, ezemithi kanye nezimboni zamakhemikhali zansuku zonke.Kuyisithako esisebenza ngezinto eziningi esinezici ezihlukile ezihlinzeka ngezinzuzo eziningi emikhiqizweni eyahlukene.Phakathi kwezinhlobo eziningi ze-HPMC, ibanga elisheshayo lamanzi abandayo lingenye yezinto eziphawulekayo, ikakhulukazi emkhakheni wamakhemikhali wansuku zonke.
(1), incazelo kanye nenqubo yokukhiqiza
Ngaphambi kokuqonda izici ze-HPMC esheshayo yebanga lamakhemikhali ebangeni lansuku zonke lamanzi abandayo, masiqale siqonde incazelo yayo kanye nenqubo yokukhiqiza.I-HPMC i-non-ionic cellulose ether, etholakala ngokwelapha i-cellulose yemvelo (njengemalitha kakotini noma i-pulp yokhuni) nge-alkali, bese i-etherifying nge-propylene oxide ne-methyl chloride.Lokhu kusabela kwamakhemikhali kukhiqiza impushana emhlophe ukuya kokumhlophe encibilika emanzini nasezincibilikisini eziphilayo.Ibanga elisheshayo lamanzi abandayo le-HPMC libhekisela ohlotsheni oluthile lwe-HPMC okulula ukuluncibilika emanzini abandayo, ngokungafani ne-HPMC evamile edinga amanzi ashisayo ukuze incibilike.Lolu shintsho olusheshayo lwamanzi abandayo lufinyelelwa ngokukhetha izinto zokusetshenziswa, ukulungisa izimo ze-etherification, nokulawula ukusabalalisa usayizi wezinhlayiyana.
(2).Izici nezinzuzo
I-HPMC esheshayo yamanzi abandayo yebanga lezimonyo inezinto ezimbalwa nezinzuzo eziyenza ibe isithako esibalulekile emikhiqizweni eminingi yokunakekelwa komuntu siqu.Nazi ezinye zezici zayo eziphawulekayo:
1. Umthamo omkhulu wokugcina amanzi: I-HPMC iyi-hydrophilic, okusho ukuthi iheha futhi igcine amanzi.I-HPMC esheshayo yebanga lamakhemikhali yansuku zonke inamandla okugcina amanzi aphezulu, okuzuzisa ukukhulisa i-viscosity nokuzinza komkhiqizo.Lesi sakhiwo siwusizo ikakhulukazi ekusuleni okumanzi, i-shampoo kanye nemikhiqizo yokugeza umzimba.
2. Izici zokwenza ifilimu: I-HPMC yenza ifilimu esobala futhi evumelana nezimo lapho yomile esikhumbeni noma ezinweleni.Le filimu ivikela isikhumba ezintweni zangaphandle ezifana nokungcola, imisebe ye-UV namakhemikhali.Yenza futhi izinwele zibukeke zicwebezela futhi zibushelelezi.Emikhiqizweni yamakhemikhali yansuku zonke, izakhiwo zefilimu ze-HPMC zivame ukusetshenziswa emikhiqizweni yesitayela sezinwele, izinto zokugcoba ezivikela ilanga, izinto zokuthambisa, njll.
3. Izici zokujiya kanye ne-emulsifying: I-HPMC ingajiya futhi ihlanganise amafomula, okusho ukuthi ingasiza ukusimamisa uwoyela namanzi emikhiqizweni.Lesi sici siwusizo ikakhulukazi emikhiqizweni yohlobo lukakhilimu njengesigcobo somzimba, ukhilimu wobuso nokhilimu wamehlo.
4. Imnene futhi ayicasuli: I-HPMC iyisithako esivumelana ne-biocompatible, esingenabuthi esingeke sibangele ukucasuka noma ukungezwani komzimba.Ithambile esikhumbeni ngaphandle kokuphazamisa i-pH yemvelo noma umgoqo we-lipid.Lesi sakhiwo sikwenza kube isithako esifanele emikhiqizweni yokunakekela izingane, imaski yobuso kanye nemikhiqizo yesikhumba esibucayi.
5. Ukuguquguquka: I-HPMC ingasetshenziswa ngokuhlangana nezinye izithako, njengama-surfactants, izilondolozi, amakha, njll., ngaphandle kokuphazamisa ukusebenza kwayo.Ingaguqulelwa ekubunjweni okuhlukene ukuze inikeze ukuthambisa, ukuthambisa, ukuhlanza nezinye izinzuzo.
(3).Inkambu yohlelo lokusebenza
I-HPMC esheshayo yebanga lamakhemikhali yansuku zonke inohlu olubanzi lwezinhlelo zokusebenza embonini yokunakekelwa komuntu siqu.Eminye yemikhiqizo evame kakhulu eyisebenzisayo yile:
1. Izinto zokusula ezimanzi: I-HPMC inganikeza ukujiya, ukugcinwa kwamanzi kanye nezakhiwo ezilungele isikhumba ezidingwa ukusula okumanzi.Ingenza ama-wipes azizwe enomswakama kakhulu, ethambile futhi ehlala isikhathi eside.
2. I-shampoo nejeli yokugeza: I-HPMC ingakhuphula i-viscosity kanye negwebu le-shampoo kanye nejeli yokugeza, ikwenze kube lula ukukusebenzisa nokuwasha.Iphinde ibe nomthelela wokulungisa izinwele nasesikhunjeni.
3. Imikhiqizo yesitayela sezinwele: I-HPMC yenza ifilimu eguquguqukayo ezungeze izinwele, esiza ukugcina isimo sayo kanye nevolumu.Iphinde ivikele izinwele ekulimaleni komswakama nokushisa.
4. Iloshini yokuvikela ilanga: I-HPMC ingasebenza njengesithuthukisi selanga ukuze ithuthukise ukusebenza kahle kokuhlunga kwe-UV.Iphinde inikeze umuzwa osilika futhi ongenawo amafutha esikhumbeni.
5. Imaski: I-HPMC inganikeza ijeli, izinto zokuthambisa kanye zokwenza ifilimu ezidingwa imaski.Isiza imaski ukunamathela esikhumbeni futhi ilethe izithako ezisebenzayo.
(4).Ekuphetheni
I-Cosmetic grade yamanzi abandayo esheshayo i-hydroxypropyl methylcellulose iyisithako sezinzuzo esisebenza ngezindlela eziningi esithuthukisa ikhwalithi nokusebenza kwemikhiqizo yokunakekelwa komuntu siqu.Amandla ayo aphezulu okugcina amanzi, izakhiwo zokwenziwa kwefilimu, izakhiwo ezijiyayo kanye ne-emulsifying, ubumnene nokuhlukahluka kwenza kube isithako esibalulekile ekwakhiweni okuningi.Ukusetshenziswa kwayo kabanzi ezintweni zokusula ezimanzi, ama-shampoos nokugeza umzimba, imikhiqizo yezinwele, izinto zokuthambisa zokuvikela ilanga, namamaski obuso kukhombisa ukuguquguquka kwayo, usizo, nokusebenza kwayo.Njengoba abathengi banezidingo eziphakeme zokusebenza, ukuphepha kanye nokusimama kwemikhiqizo yokunakekelwa komuntu siqu, i-HPMC esheshayo yezinga lamakhemikhali nsuku zonke ingase idlale indima ebaluleke kakhulu embonini.
