Hydroxypropyl Methylcellulose (HPMC)imhando ye nonionic cellulose ether inobva mu cellulose yechisikigo. Nekuda kwekuchengetedzeka kwayo, kugadzikana kwayo uye kushanda kwayo kwakasimba, inoshandiswa zvakanyanya muzvigadzirwa zvemazuva ano zvemakemikari uye zvekuchengetedza ganda. Ingave lotion, kirimu, kuchenesa kumeso kana essence, HPMC ine basa rakakosha mukugadzikana kwesystem, kuvandudza kunzwa kweganda uye kugadzirwa kwefirimu, uye chinhu chinowanzo shandiswa muzvizoro.
1. Kukora uye mhedzisiro yekutonga kwe rheological
Rimwe remabasa akakosha eHPMC kukora. Muchikamu chemvura, macheni ayo emolecular anogona kunwa mvura nekukura, zvichiwedzera viscosity yesystem uye zvichiita kuti chigadzirwa chive chakapfava uye chakapfava. Kusiyana necarbomer ne xanthan gum, HPMC chinhu chinogokora chisina kusimba chinogona kugadzira viscosity yakagadzikana pasina kuvimba ne pH neutralization. Saka, inonyanya kukodzera mafomula ekuchengetedza ganda ane acidic kana asina acid, akadai seane AHA/BHA, VC derivatives, uye whitening essences.
Pamusoro pezvo, HPMC ine kugona kwakanaka kwekutonga rheological properties. Chigadzirwa ichi chinoratidza kusviba kwakaderera uye chiri nyore kushandisa panguva yekubuda, ukuwo chichichengetedza chimiro chakakwirira panguva yakamira, izvo zvinobatsira kuti zvinwiwa kana majeli zvirambe zvakagadzikana. Izvi zvakakosha zvikuru kune zvigadzirwa zvinoda kupfava uye kuwedzera, zvakaita sezvishandiso zvekuchenesa kumeso, kirimu yemaziso, uye zvinwiwa zvemasiki.
2. Kugadzikana kwe emulsification uye dziviriro yekumisikidzwa
Mumasystem emafuta-mvura akadai seemulsions nemakirimu ekumeso, HPMC inogona kuwedzera kugadzikana kwe emulsification kuburikidza nekukora uye nzira dzekudzivirira interface. Maketani ayo emolecular achaumba jira rinodzivirira rakatenderedza madonhwe eemulsion, zvichidzivirira madonhwe emafuta kuti asaungane uye kuwedzera kugadzikana kwekupisa uye kugadzikana kwekuchengetedza kwesystem. Kune mafomula ane huwandu hwakawanda hwemafuta emiriwo, silicone oil kana active ingredient dispersions, HPMC inogona kuderedza zvakanyanya kupatsanurwa uye kuparadzaniswa kwemafuta, uye kuwedzera hupenyu hwesherufu.
Panguva iyi, HPMC inogonawo kupa simba rekumisa bvudzi, zvichiita kuti hupfu hwegranular (hwakadai setitanium dioxide, zinc oxide, uye pearl powder) huparadzirwe zvakaenzana pasina kugadzikana. Inoshandiswa zvakanyanya muzvigadzirwa zvakaita se sunscreens, shampoos, uye scrubs.
3. Kuvandudza kutaridzika kweganda uye ruzivo rwekushandisa
HPMC ine kumeso kwakapfava kwakasiyana. Kana ichienzaniswa nemamwe macolloid echisikigo (akadai seguar gum ne xanthan gum), haina kunamira zvakanyanya uye haina mitsetse, izvo zvinogona kupa chigadzirwa ichi kunzwa kunozorodza senge mvura kana segel. Yakakodzera zvakanyanya kune ganda remazuva ano rekuchengetedza ganda "rakapfava, rakatetepa uye risingaremi".
Gel yayo inonyungudika mumvura inoita kuti ganda rive rakapfava uye rakafanana, zvichiita kuti riwedzere kunyorova uye kukura kwechigadzirwa chapera, zvichiita kuti vashandisi vanzwe vakapfava uye vakapfava pavanenge vachishandisa essence, eye cream kana lotion.
4. Kugadzira mafirimu uye kunyorovesa
HPMC inogona kugadzira firimu rekudzivirira rinoonekera, rinochinjika uye rinofema pamusoro peganda, uye ine mabhenefiti anotevera:
Kuvhara hunyoro uye kunyorovesa: Deredza kupwa kwemvura kuti ganda rirambe riine mvura.
Wedzera nguva yekuchengetedza zvinhu zvinoshanda: Zvinhu zvinoshanda zvakaita se hyaluronic acid, niacinamide, VC, uye ceramide zvinogona kuramba zvichikanganisa ganda.
Wedzera kunzwa kweganda mushure mekunge chigadzirwa chagadzira firimu: Gadzira firimu rinonyorovesa uye risingabatike kuti ganda rive rakatsetseka nekukurumidza.
Iyi nzira yekugadzira firimu inoita kuti HPMC ive yakakurumbira muzvinwiwa zvemasiki, mafirimu echando, maessence uye zvigadzirwa zvinosiya.
5. Hazvina kupfava, zvakachengeteka uye zvinogona kugadziriswa nyore nyore
Sechinhu chinobva mu cellulose yechisikigo, HPMC yakachengeteka zvikuru, haina kushatirwa kwakanyanya uye haina allergies, ichizadzisa zvinodiwa zvemakemikari emazuva ano emazuva ano emafuta akapfava. Ine pH yakakura uye haipindiri nezvinhu zvakajairika zvinoshanda, nokudaro inoenderana nezvinhu zvakawanda zvekuchengetedza ganda, kusanganisira
Mavhitamini (VC, VE, panthenol)
Asidhi (lactic acid, salicylic acid)
Zvinonhuhwirira zvinonyorovesa (glycerin, propylene glycol)
Sisitimu yeSurfactant (Mishonga yekuchenesa kumeso nemashampoo)
Zvinotorwa pamiti nezvinhu zvinoshanda
Kuenderana uku kwakakura kunoita kuti HPMC ive chinhu chinobatsira zvikuru chinoshandiswa zvakanyanya muindasitiri yemakemikari yezuva nezuva.
6. Kuvandudza kugadzikana kwechitarisiko uye magadzirirwo echigadzirwa
HPMC yakavandudza zvakanyanya chitarisiko uye kugadzikana kwemuviri wezvigadzirwa zvekuchengetedza ganda
Dzivirira gel kana kirimu kuti isatsvedze uye isaparadzanise mvura
Wedzera kujeka uye kupenya
Ita kuti fomura iratidze kuyerera kwakafanana
Kuvandudza kugona kwekuchengetedza viscosity mushure mekuchengetwa kwenguva refu
Saka, inowanzoshandiswa senzira yekugadzirisa ganda muzvinwiwa zvemasiki zvepamusoro, majeli, uye zvigadzirwa zvekuchengetedza ganda.
HPMCimhando yezvinhu zvakagadzirwa nemakemikari neganda zvinoshandiswa zuva nezuva, uye mabasa ayo anofukidza zvinhu zvakawanda zvakaita sekukora, kudzora rheological, emulsification uye stabilization, suspension, firimu, moisturizing, uye kuvandudza kunzwa kweganda. Nekuda kwekuchengetedzeka kwayo kwakanyanya, kushanda kwayo kwakasimba uye kugona kwayo kuchinja mafomura, chinhu chakakosha muzvigadzirwa zvakasiyana-siyana zvekuchengetedza ganda, zvinosanganisira mafuta ekuchenesa, ma essence, masks, cleansers, sprays uye gels. Kune zvigadzirwa zvemazuva ano zvekuchengetedza ganda zvinotevera kunzwa kweganda kwakapfava, kwakasimba uye kunozorodza, HPMC chinhu chakakosha chekusimudzira kunaka kwechigadzirwa.
