Carbomer uye hydroxyethylcellulose (HEC) zvese zviri zviviri zvinowanzoshandiswa mumaindasitiri akasiyana, kunyanya mune zvekuzora, zvemishonga, uye zvigadzirwa zvekuchengeta munhu. Kunyangwe mashandisirwo azvo akafanana seaya anokora uye anosimbisa, ane akasiyana makemikari anoumbwa, zvivakwa, uye mashandisirwo.
1. Kuumbwa Kwemakemikari:
Carbomer: Carbomers anogadzirwa akakwira molecular huremu mapolymers e acrylic acid muchinjiko-akabatanidzwa ne polyalkenyl ethers kana divinyl glycol. Iwo anowanzo kugadzirwa kuburikidza ne polymerization reactions.
Hydroxyethylcellulose: Hydroxyethylcellulose, kune rumwe rutivi, inobva kune cellulose, inowanzoitika polima. Iyo inogadzirwa nekurapa cellulose ne sodium hydroxide uye ethylene oxide kuunza hydroxyethyl mapoka pane cellulose musana.
2. Molecular Structure:
Carbomer: Carbomers vane branched molecular chimiro nekuda kwechimiro chavo chemuchinjikwa. Iyi branching inobatsira pakukwanisa kwavo kuumba matatu-dimensional network kana hydrated, zvichiita kuti ibudirire kukora uye gelling zvinhu.
Hydroxyethylcellulose: Hydroxyethylcellulose inochengetedza mutsara chimiro che cellulose, ine hydroxyethyl mapoka akabatanidzwa kune mayuniti eglucose pamwe ne polymer cheni. Iyi mutsara chimiro inokanganisa maitiro ayo seyakakora uye inodzikamisa.
3. Solubility:
Carbomer: Carbomers anowanzo kupihwa muhupfu uye haanyungudika mumvura. Nekudaro, ivo vanogona kuzvimba uye hydrate mune aqueous mhinduro, vachigadzira akajeka gels kana viscous dispersions.
Hydroxyethylcellulose: Hydroxyethylcellulose inowanikwawo muupfu asi inonyungudika zviri nyore mumvura. Inonyungudika kuti igadzire mhinduro dzakajeka kana zvishoma turbid, zvichienderana nekusangana uye zvimwe zvikamu zvekugadzira.
4. Kukora Zvivakwa:
Carbomer: Carbomers anokora zvakanyanya uye anogona kugadzira viscosity mune dzakasiyana siyana maumbirwo, kusanganisira makirimu, gels, uye lotions. Ivo vanopa yakanakisa kumisa zvivakwa uye inowanzoshandiswa kudzikamisa emulsions.
Hydroxyethylcellulose: Hydroxyethylcellulose inoshandawo seyakakora asi ichiratidza hunhu hwakasiyana hwekurevesa zvichienzaniswa nemacarbomers. Inopa pseudoplastic kana shear-kutetepa kuyerera kune maumbirwo, zvichireva kuti viscosity yayo inoderera pasi pekunetseka kweshear, kufambisa nyore kushandisa uye kupararira.
5. Kugarisana:
Carbomer: MaCarbomers anowirirana nehuwandu hwakawanda hwezvizoro zvekushongedza uye pH mazinga. Nekudaro, ivo vangangoda neutralization nealkalis (semuenzaniso, triethanolamine) kuti iwane yakanyanya kukora uye gelling zvivakwa.
Hydroxyethylcellulose: Hydroxyethylcellulose inoenderana neakasiyana-siyana zvinonyungudutsa uye zvakajairika cosmetic ingredients. Iyo yakagadzikana pamusoro pehupamhi pH renji uye haidi neutralization yekukora.
6. Nzvimbo dzekushandisa:
Carbomer: Carbomers vanowana kushandiswa kwakakura muzvigadzirwa zvekuchengeta zvega senge makirimu, lotions, gels, uye magadzirirwo ekuchengeta bvudzi. Iwo anoshandiswawo muzvigadzirwa zvemishonga senge topical gels uye ophthalmic solutions.
Hydroxyethylcellulose: Hydroxyethylcellulose inowanzo shandiswa muzvizoro uye zvekuchengeta magadzirirwo emunhu, anosanganisira shampoos, maconditioners, kugeza muviri, uye mushonga wemazino. Inoshandiswawo mumishonga yemishonga, kunyanya mukugadzirwa kwepamusoro.
7. Sensory Characteristics:
Carbomer: Carbomer gels anowanzo kuratidza yakatsetseka uye yakasviba mameseji, ichipa inodiwa yekunzwa ruzivo kune maumbirwo. Nekudaro, ivo vanogona kunzwa zvishoma tacky kana kunamatira pane application mune dzimwe nguva.
Hydroxyethylcellulose: Hydroxyethylcellulose inopa silky uye isina kunamira kunzwa kune maumbirwo. Hunhu hwayo hwekuveura-kutetepa hunobatsira kupararira kuri nyore uye kunyura, kuwedzera ruzivo rwemushandisi.
8. Regulatory Kufunga:
Carbomer: MaCarbomers anowanzo zivikanwa seakachengeteka (GRAS) nezviremera zvinodzora kana zvichishandiswa zvinoenderana nemaitiro akanaka ekugadzira (GMP). Nekudaro, zvakatemwa zvekutonga zvinodikanwa zvinogona kusiyana zvichienderana nekwakatarisirwa kushandiswa uye dunhu renzvimbo.
Hydroxyethylcellulose: Hydroxyethylcellulose inoonekwa zvakare yakachengeteka kuti ishandiswe muzvizoro uye mishonga, ine mvumo yekutonga kubva kune vane chiremera. Kutevedzera mirau inoshanda uye nhungamiro kwakakosha pakuona kuchengetedzwa kwechigadzirwa uye kushanda.
nepo zvese zviri zviviri carbomer uye hydroxyethylcellulose zvinoshanda seanoshanda thickeners uye stabilizers mune akasiyana mafomati, iwo anosiyana maererano nemakemikari anoumbwa, mamorekuru chimiro, solubility, thickening zvivakwa, kuwirirana, nzvimbo dzekushandisa, hunhu hwekunzwa, uye kufunga kwekutonga. Kunzwisisa misiyano iyi kwakakosha kune vanogadzira kuti vasarudze iyo inonyanya kufanira yezvigadzirwa zvavanoda uye maitiro ekuita.
