Hydroxyethylcellulose vs carbomer

Hydroxyethylcellulose (HEC) na karbomer ni polymers ebyiri zikoreshwa cyane mubikorwa byo kwita kubantu. Bafite imiterere yimiti nuburyo butandukanye, ibyo bigatuma bikoreshwa mubikorwa bitandukanye.

HEC ni polymer karemano, amazi ashonga polymer akomoka kuri selile. Bikunze gukoreshwa nkibibyimbye, emulisiferi, na stabilisateur mubicuruzwa bitandukanye byita kumuntu nka shampo, kondereti, no koza umubiri. HEC izwiho guhuza cyane nibindi bikoresho hamwe nubushobozi bwayo bwo gutanga ibintu byoroshye kandi bisize amavuta. Azwiho kandi gusobanuka neza n'uburozi buke.

Ku rundi ruhande, Carbomer, ni sintetike, ya molekile iremereye ya polymer isanzwe ikoreshwa nkigikoresho cyo kubyimba mubicuruzwa bitandukanye byita kumuntu nka geles hamwe namavuta yo kwisiga. Irakora neza cyane mubyimbye no gutuza, kandi irashobora gutanga urwego rwo hejuru rusobanutse no guhagarikwa kubicuruzwa byarangiye. Carbomer izwiho kandi kugenzura neza ububobere nubushobozi bwo kuzamura ibicuruzwa.

Imwe muntandukanyirizo nyamukuru hagati ya HEC na carbomer nubushobozi bwamazi. HEC irashonga cyane mumazi, mugihe carbomer isaba kutabogama hamwe na alkaline nka triethanolamine cyangwa hydroxide ya sodium kugirango ihindurwe neza kandi ikabyimbye. Byongeye kandi, HEC izwiho kutumva neza pH nimpinduka zubushyuhe, mugihe karbomer ishobora guterwa nimpinduka za pH nubushyuhe.

Muncamake, HEC na carbomer nubwoko bubiri butandukanye bwa polymers hamwe nibintu byihariye hamwe nibisabwa. HEC ni polymer karemano, ikabura amazi mumazi ikunze gukoreshwa nkibyimbye na emulisiferi, mugihe karbomer ni sintetike, uburemere buke bwa polymer ikora cyane muburyo bwo kubyimba no gutuza. Guhitamo polymer biterwa nibikenewe byihariye nibiranga formulaire.
