Hydroxyethyl Methyl Cellulose (MHEC) waa ethers nonionic cellulose ethers oo biyo ah, kuwaas oo loo bixiyo sida budo qulqulaya oo bilaash ah ama qaab cellulose ah.
Hydroxyethyl Methyl Cellulose (MHEC) waxay ka samaysan tahay suuf-cellulose aad u saafi ah iyada oo falcelinta etherification hoos yimaada xaaladaha alkaline iyada oo aan la helin xubnaha xayawaanka, baruurta iyo qaybaha kale ee bioactive.MHEC waxay u muuqataa inay tahay budo cad oo aan ur lahayn oo aan dhadhamin.Waxaa lagu gartaa hygroscopicity oo aan si dhib leh ugu milmin biyaha kulul, acetone, ethanol iyo toluene.Biyaha qabow MHEC waxay ku barari doontaa xal kolloidal ah, kali ahaanshadeeduna ma saameynayso qiimaha PH. Si la mid ah methyl cellulose marka lagu daro kooxaha HDroxyethyl.MHEC aad bay u adkaysanaysaa milixda, si fudud ayay ugu milmi kartaa biyaha waxayna leedahay heerkul sare oo jel ah.
MHEC waxaa sidoo kale loo yaqaan HEMC, Methyl Hydroxyethyl Cellulose, kaas oo loo isticmaali karo sida wakiilka haynta biyaha hufan, stabilizer, koollada iyo wakiilka film-samaynta ee dhismaha, xabagta tile, sibidhka iyo malaasyada ku salaysan gypsum, saabuun dareere ah, iyo codsiyo kale oo badan.
