Hydroxypropylmethylcellulose (HPMC) is a cellulose-derived polymer inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira ekuvaka, emishonga uye emazuva ese emakemikari maindasitiri.Icho chinhu chakawanda chinoshanda chine yakasarudzika zvivakwa zvinopa akawanda mabhenefiti mune akasiyana zvigadzirwa.Pakati pemhando dzakawanda dzeHPMC, giredhi yemvura inotonhora yekukurumidza ndeimwe yeakakosha, kunyanya mumunda wemakemikari ezuva nezuva.
(1), tsananguro uye maitiro ekugadzira
Tisati tanzwisisa hunhu hwemazuva ese kemikari giredhi yemvura inotonhorera ipapo HPMC, ngatitangei kunzwisisa tsananguro yayo uye maitiro ekugadzira.HPMC is a non-ionic cellulose ether, iyo inowanikwa nekurapa yakasikwa cellulose (yakadai sedonje linters kana huni pulp) ane alkali, uye ipapo etherifying pamwe propylene oxide uye methyl chloride.Mushonga uyu wekemikari unoburitsa hupfu huchena kuenda kuhuchena hunonyungudika mumvura nezvinonyungudutsa.Mvura inotonhora yekukurumidza giredhi yeHPMC inoreva imwe mhando yeHPMC iri nyore kunyungudika mumvura inotonhora, kusiyana neyakajairwa HPMC inoda mvura inopisa kuti inyunguduke.Iyi shanduko yekukurumidza yemvura inotonhora inowanikwa nekusarudza zvigadzirwa, kugadzirisa etherification mamiriro, uye kudzora particle size distribution.
(2).Zvimiro uye zvakanakira
Cosmetic giredhi yemvura inotonhora ipapo HPMC ine akati wandei zvivakwa uye mabhenefiti anoita kuti ive chinhu chakakosha muzvigadzirwa zvakawanda zvekuchengeta munhu.Heano mamwe emhando dzayo dzinozivikanwa:
1. Mvura yakakwirira yekuchengetedza simba: HPMC inonzi hydrophilic, zvinoreva kuti inokwezva uye inochengetedza mvura.Zuva nezuva kemikari giredhi yemvura inotonhorera pakarepo HPMC ine yakakwirira yekuchengeta mvura, iyo inobatsira kuwedzera viscosity uye kugadzikana kwechigadzirwa.Ichi chivakwa chinonyanya kukosha mukupusika kwemvura, shampoo uye zvigadzirwa zvekugeza muviri.
2. Mafirimu ekugadzira zvinhu: HPMC inoumba firimu rakajeka uye rinoshanduka kana rakaoma paganda kana bvudzi.Iyi firimu inodzivirira ganda kubva kune zvekunze zvinhu zvakadai sekusvibiswa, UV rays uye makemikari.Inoitawo kuti bvudzi rive rakajeka uye rakapfava.Muzvigadzirwa zvemakemikari zvemazuva ese, iyo firimu-inogadzira zvimiro zveHPMC inowanzoshandiswa mukugadzira bvudzi zvigadzirwa, sunscreen lotions, moisturizers, nezvimwe.
3. Kuomesa uye emulsifying zvinhu: HPMC inogona kukobvu uye emulsify mafomula, zvinoreva kuti inogona kubatsira kudzikamisa mafuta nemvura muzvigadzirwa.Iyi ficha inonyanya kukosha muzvigadzirwa zvemhando yekrimu senge lotion yemuviri, cream kumeso uye eye cream.
4. Zvinyoro uye zvisingasviki: HPMC ndeye biocompatible, isiri-chepfu iyo haizokonzeri kutsamwa kana kusawirirana.Yakapfava paganda pasina kukanganisa yakasikwa pH kana lipid barriers.Ichi chivakwa chinoita kuti ive chinhu chakakodzera muzvigadzirwa zvekuchengeta vana, masks echiso uye zvigadzirwa zveganda rinonzwa.
5. Kushanda kwakasiyana-siyana: HPMC inogona kushandiswa pamwe chete nezvimwe zvinoshandiswa, zvakadai sema surfactants, kuchengetedza, zvinonhuwira, nezvimwewo, pasina kukanganisa kushanda kwayo.Inogona kuchinjirwa kune akasiyana magadzirirwo kuti ape kunyorova, kunyaradza, kuchenesa uye zvimwe zvinobatsira.
(3).Nzvimbo yekushandisa
Zuva rega rega kemikari giredhi yemvura inotonhorera ipapo HPMC ine huwandu hwakasiyana hwekushandisa muindasitiri yekuchengeta wega.Zvimwe zvezvigadzirwa zvinonyanya kuishandisa ndezvi:
1. Wet wipes: HPMC inogona kupa kukora, kuchengetedza mvura uye ganda-inoshamwaridzika zvivakwa zvinodiwa nekunyorova wipes.Inogona kuita kuti zvipukuta zvinzwe zvakanyorova, zvinyoro uye zvakasimba.
2. Shampoo uye gel yekugeza: HPMC inogona kuwedzera viscosity uye kupupa kweshambuu uye gel yekugeza, zvichiita kuti zvive nyore kuisa nekusuka.Iyo inewo maitiro ekugadzirisa bvudzi uye ganda.
3. Zvigadzirwa zvekugadzira bvudzi: HPMC inoumba firimu inoshanduka yakakomberedza bvudzi, inobatsira kuchengetedza chimiro chayo uye huwandu.Inodzivirirawo bvudzi kubva kune unyoro uye kukuvara kwekupisa.
4. Sunscreen lotion: HPMC inogona kuita semushonga wezuva kuti uwedzere kushanda kweUV kusefa.Inopawo silky uye isina-greasy kunzwa kune ganda.
5. Mask: HPMC inogona kupa gel, moisturizing uye firimu-kugadzira zvinhu zvinodiwa nemasikisi.Inobatsira mask kunamatira kune ganda uye kuendesa zvinhu zvinoshanda.
(4).mukupedzisa
Cosmetic giredhi inotonhora mvura instant hydroxypropyl methylcellulose chinhu chakawanda chinobatsira chinobatsira icho chinosimudzira kunaka uye kuita kwezvigadzirwa zvekuchengeta munhu.Yayo yakakwirira yekuchengetedza mvura, firimu-kuumba zvimiro, kukora uye emulsifying zvimiro, unyoro uye kuita kwakasiyana-siyana kunoita kuti ive chinhu chakakosha mukuumbwa kwakawanda.Kushandiswa kwayo kwakapararira mukupukuta kwemvura, mashamposi uye kugeza muviri, zvigadzirwa zvebvudzi, mafuta ekuzora zuva, uye masks ekumeso kunoratidza kugona kwayo, kushandiswa, uye kushanda kwayo.Sezvo vatengi vane zvidikanwi zvepamusoro zvekushanda, kuchengetedzeka uye kusimba kwezvigadzirwa zvekuchengetedza, zvemazuva ese kemikari giredhi remvura inotonhorera ipapo HPMC inogona kuita basa rinowedzera kukosha muindasitiri.
