Hydroxypropyl Methylcellulose (HPMC) muSanitizer yemaoko

Hydroxypropyl Methylcellulose (HPMC)imhando ye ether isingashandisi ionic cellulose, inoshandiswa zvakanyanya muindasitiri yemakemikari yezuva nezuva, kunyanya muzvigadzirwa zvekuchenesa zvakaita se sanitizer yemaoko, facial cleanser, shampoo, shower gel, nezvimwewo. Mabasa ayo makuru anosanganisira kukora, stable suspension, film-forming moisturizing, uye kunatsiridza kubata.

1. Hunhu hwekutanga hweHPMC

HPMC ipolymer inonyungudika mumvura yakagadzirwa ne cellulose yechisikigo uye yakagadziriswa nemakemikari. Inokwanisa kuenderana nehupenyu uye kuora kwehupenyu. Ipolymer isiri ionic inogona kunyungudika mumvura inotonhora kuti igadzire mhinduro yakajeka, ine viscous colloidal. Nekuda kwekunyungudika kwayo kwakanaka, kugona kwayo kudzora viscosity uye kuchengetedzeka kwakanyanya, inoshandiswa zvakanyanya muminda yezvekudya, yemishonga uye yemakemikari ezuva nezuva.

2. Basa guru reHPMC mukuchenesa maoko

2.1. Chinokora

Basa guru reHPMC nderekushandiswa sechinosimbisa. Chinochenesa maoko chinoda kusviba kwakakodzera kuitira kuti chisave nyore kurasikirwa nacho, chive nyore kudzora uye chishandise kana chishandiswa nevashandisi. HPMC inogona kuwedzera kusviba kwechigadzirwa ichi kana chakanyanya kuderera, zvichiita kuti chinochenesa maoko chive nehunyanzvi hwakakodzera hwe rheological, zvichiwedzera kubata kwacho uye ruzivo rwemushandisi.

2.2. Zvinosimbisa uye zvinomisa kumisa

Mishonga yekuchenesa maoko inogona kunge iine zvinhu zvakasiyana-siyana zvakaita semafuta anokosha, zvinhu zvinorwisa mabhakitiriya, microcapsule particles kana pearlescent agents. HPMC ine simba rakanaka re emulsification uye hunhu hwekumisikidza, izvo zvinogona kudzivirira zvinhu izvi kubva mukupatsanurwa kana kunaya kwemvura, uye kuvandudza kugadzikana uye kufanana kwechitarisiko chemishonga yekuchenesa maoko.

2.3. Kuvandudza kuyerera uye ruzivo rwekushandisa

Nekuda kwesimba re HPMC solution (kuchekerera ganda), ine viscosity yakakura kana isina simba rakawanda, asi viscosity inoderera kana mushandisi akadzvanya nekukwesha, zvichiita kuti ive nyore kushandisa pasina kusiya kunzwa kunamira. Chinhu ichi chinoenderana zvikuru nekuisa mushonga wekuchenesa maoko se "zviri nyore kushandisa uye zvinonyaradza kushandisa".

2.4. Kugadzirwa kwefirimu uye kunyorovesa

HPMC ine hunhu hwekugadzira firimu uye inogona kugadzira firimu rakatetepa rine mhepo yakanaka pamusoro peganda, izvo zvinoita basa rekudzivirira uye kuvharira mvura. Inogona zvakare kuwedzera kunyorova kweganda uye kubatsira kuderedza kushatirwa kwesipo paganda. Ndiyo imwe yemishonga inonyanya kushandiswa mukuchenesa zvinyoro nyoro.

2.5. Kuvandudza chitarisiko chechigadzirwa

Kuchenesa maoko zvakanyanya inzira huru inoshandiswa pakuchenesa maoko. Kana HPMC yanyungudika, inoumba mhinduro yakajeka uye yakajeka, iyo isingakanganisi chitarisiko chechigadzirwa. Inogona zvakare kushandiswa ne pearlescent agents kuwedzera kutaridzika kwechigadzirwa uye kuwedzera kutaridzika kwepamusoro kwechigadzirwa.

3. Mashandisirwo anoitwa HPMC mu sanitizer yemaoko

Munzira yekuchenesa nemaoko, HPMC inowanzoiswa muchimiro cheupfu. Kuti ive nechokwadi chekuti yanyungudika zvizere uye kudzivirira kusangana, zvinokurudzirwa kuiparadzira mumvura inotonhora uye kuikurunga zvakanaka, wozoipisa kuti ikurumidze kunyungudika. Huwandu hunowanzo shandiswa i0.1% ~ 0.8%, zvichienderana nehukuru hwe viscosity hunodiwa uye mhedzisiro yekubatana kwezvimwe zvinhu zviri mufomura.

4. Zvakanakira kushandisa HPMC

Yakachengeteka uye haitsamwisi: HPMC chinhu chinobva mu cellulose chisiri ionic, hachina chepfu uye hachinhuwi, hachina kutsamwisa ganda nemaziso, uye chakakodzera zvigadzirwa zvinoshandiswa nevana kana ganda rinonzwa kurwadza.

Inoora: Ichinhu chisina njodzi kune zvakatipoteredza, chinoenderana nekugadzirwa kwezvizoro zvegirini.

Kuenderana kwakasimba: Inogona kushanda zvakanaka nemarudzi akasiyana-siyana emasurfactants, manakiro, zvinochengetedza nezvimwe zvinoshandiswa, uye haiwanzoitiki kuti fomura isagadzikane.

Mutengo unodzorwa: Kana tichienzanisa nezvimwe zvinosimbisa zvakagadzirwa nepolymer, HPMC inodhura zvishoma uye isingadhuri uye inogara kwenguva refu.

5. Kudzivirira nematambudziko

5.1. Nzira yekunyungudutsa inofanira kudzorwa zvine mwero

Kana mashandiro asina kunaka, matambudziko akadai sekuungana pamwe chete uye kusanyungudika kwakakwana zvinogona kuitika, zvichikanganisa kunaka kwechigadzirwa. HPMC inofanira kuwedzerwa zvishoma nezvishoma ichikurunga uye ichinyungudika zvizere patembiricha yakakodzera.

5.2. Hunhu hwakasiyana hwekuchinjika ku pH

HPMC inogara yakagadzikana kana pH iri pakati pe4 ne11. Kana fomura yekuchenesa maoko iine acid yakasimba kana alkali yakasimba, kugadzikana kwayo uye kuchengetedza viscosity zvinofanirwa kucherechedzwa.

5.3. Kunzwa tembiricha

Kusimba kweHPMC kuchaderera kana tembiricha yakakwira. Kana fomura yekuchenesa maoko ichida kucheneswa patembiricha yakakwira, kugadzikana kwayo pakupisa kunofanira kuyedzwa.

Kushandiswa kweHPMCMushonga wekuchenesa maoko unoratidza zvinodiwa zviviri zvezvigadzirwa zvemazuva ano zvemakemikari kuti "zvishande zvakanaka + zvakachengeteka". Haisi kungovandudza magadzirirwo uye mashandiro echigadzirwa, asiwo inofunga nezvekuchengetedzwa kwezvakatipoteredza uye budiriro inoenderera mberi. Sezvo zvinodiwa nevatengi zvemhando yepamusoro yezvigadzirwa zvekuchenesa zvichiramba zvichiwedzera, HPMC, sechigadzirwa chinoshanda zvakawanda, chakachengeteka uye chakagadzikana, ichaita basa rakakosha mukuchenesa maoko nezvimwe zvigadzirwa zvekuchenesa nekuchengetedza ganda. Kumakambani emakemikari ezuva nezuva, kushandiswa kwesainzi uye zvine musoro kweHPMC hakungogone kungosimudzira kukwikwidza kwechigadzirwa chete, asiwo kubatsira kugadzira chifananidzo chinokwezva chemhando.
