Carbomer na hydroxyethylcellulose (HEC) byombi bikoreshwa cyane mubikorwa bitandukanye, cyane cyane kwisiga, imiti, nibicuruzwa byita kumuntu. Nuburyo busa nkibikorwa byo kubyimba hamwe na stabilisateur, bifite imiti itandukanye yimiti, imiterere, nibisabwa.
1. Ibigize imiti:
Carbomer: Carbomers ni sintetike yuburemere bwa molekuline yuburemere bwa aside ya acrylic ihujwe na ethers ya polyalkenyl cyangwa divinyl glycol. Mubisanzwe byakozwe muburyo bwa polymerisiyasi.
Hydroxyethylcellulose: Hydroxyethylcellulose, kurundi ruhande, ikomoka kuri selile, polymer isanzwe ibaho. Ihingurwa no kuvura selile hamwe na hydroxide ya sodium na okiside ya Ethylene kugirango yinjize amatsinda ya hydroxyethyl kumugongo wa selile.
2. Imiterere ya molekulari:
Carbomer: Carbomers ifite imiterere ya molekile ishami bitewe na kamere ihuza. Iri shami rigira uruhare mubushobozi bwabo bwo gukora urusobe rwibice bitatu iyo ruyobowe, biganisha kubyimbye neza.
Hydroxyethylcellulose: Hydroxyethylcellulose igumana imiterere yumurongo wa selile, hamwe nitsinda rya hydroxyethyl rifatanije nibice bya glucose kumurongo wa polymer. Imiterere yumurongo igira ingaruka kumyitwarire yayo nkibyimbye na stabilisateur.
3. Gukemura:
Carbomer: Carbomers mubisanzwe itangwa muburyo bwifu kandi ntibishobora gushonga mumazi. Nyamara, zirashobora kubyimba no kuyobya amazi mubisubizo byamazi, bigakora gele ibonerana cyangwa ikwirakwizwa ryinshi.
Hydroxyethylcellulose: Hydroxyethylcellulose nayo itangwa muburyo bwifu ariko byoroshye gushonga mumazi. Irashonga kugirango ikore ibisubizo bisobanutse cyangwa bituje gato, bitewe nubushakashatsi hamwe nibindi bikoresho.
4. Ibyiza byo kubyimba:
Carbomer: Carbomers ikora neza cyane kandi irashobora gutera ubukonje muburyo butandukanye, harimo amavuta, geles, hamwe na lisansi. Zitanga ibintu byiza byo guhagarika kandi akenshi bikoreshwa muguhagarika emulisiyo.
Hydroxyethylcellulose: Hydroxyethylcellulose nayo ikora nkibyimbye ariko ikagaragaza imyitwarire itandukanye ya rheologiya ugereranije na karubone. Itanga pseudoplastique cyangwa shear-thinning flow to formulaire, bivuze ko ububobere bwayo bugabanuka mugihe cyogosha, byoroshe gukoreshwa no gukwirakwira.
5. Guhuza:
Carbomer: Carbomers irahujwe nibintu byinshi byo kwisiga hamwe nurwego rwa pH. Ariko, barashobora gusaba kutabogama hamwe na alkalis (urugero, triethanolamine) kugirango bagere kubyimbye byiza.
Hydroxyethylcellulose: Hydroxyethylcellulose ihujwe numuti utandukanye hamwe nibintu bisanzwe byo kwisiga. Irahagaze hejuru ya pH yagutse kandi ntisaba kutabogama kubyimbye.
6. Ahantu ho gusaba:
Carbomer: Carbomers isanga ikoreshwa cyane mubicuruzwa byita kumuntu nka cream, amavuta yo kwisiga, geles, hamwe no gutunganya umusatsi. Zikoreshwa kandi mubicuruzwa bya farumasi nka geles yibanze hamwe nibisubizo byamaso.
Hydroxyethylcellulose: Hydroxyethylcellulose ikoreshwa muburyo bwo kwisiga no kwita kubantu, harimo shampo, kondereti, koza umubiri, hamwe nu menyo. Irakoreshwa kandi mubikorwa bya farumasi, cyane cyane mubikorwa byingenzi.
7. Ibiranga ibyumviro:
Carbomer: Ububiko bwa Carbomer busanzwe bwerekana uburyo bworoshye kandi busize amavuta, butanga uburambe bwibyifuzo byingirakamaro. Nubwo bimeze bityo ariko, barashobora kumva bituje cyangwa bikomye kubisabwa mubihe bimwe.
Hydroxyethylcellulose: Hydroxyethylcellulose itanga silike kandi idafatanye kumva. Imyitwarire yayo yogosha igira uruhare muburyo bworoshye bwo gukwirakwizwa no kwinjizwa, byongera uburambe bwabakoresha.
8. Ibitekerezo bigenga:
Carbomer: Carbomers muri rusange izwi nkumutekano (GRAS) ninzego zishinzwe kugenzura iyo zikoreshejwe muburyo bwiza bwo gukora (GMP). Ariko, ibisabwa byihariye bigenga amategeko birashobora gutandukana bitewe nibisabwa hamwe n'akarere.
Hydroxyethylcellulose: Hydroxyethylcellulose nayo ifatwa nkumutekano kugirango ikoreshwe mu kwisiga no mu miti, byemejwe n’ubuyobozi bubishinzwe. Kubahiriza amabwiriza n'amabwiriza akurikizwa ni ngombwa mu kurinda umutekano w'ibicuruzwa no gukora neza.
mugihe byombi bya karbomer na hydroxyethylcellulose bikora nkibibyibushye hamwe na stabilisateur muburyo butandukanye, biratandukanye mubijyanye nimiterere yimiti, imiterere ya molekile, solubile, imiterere yibyibushye, guhuza, ahantu hashyirwa mubikorwa, ibiranga amarangamutima, no gutekereza kubitekerezo. Gusobanukirwa itandukaniro nibyingenzi kubashinzwe guhitamo ibintu bikenewe kubicuruzwa byabo byihariye nibisabwa.
