Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, fududeeya propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, soo gaabinta), waa inay ka tirsan yihiin noocyo kala duwan oo ah ether cellulose aan ionic ahayn oo isku dhafan. Waa semi-synthetic, aan firfircoonayn, polymer viscoelastic ah oo caadi ahaan loo isticmaalo cilmiga indhaha sida saliidayn ahaan, ama saafiye ahaan ama kaxeeya dawooyinka afka, sida caadiga ah laga helo badeecooyin kala duwan oo kala duwan. Hydroxypropyl cellulose waxaa loo isticmaali karaa cunto lagu daro, emulsifier, dhumuc weyn, wakiilka ganaaxa iyo beddelka jelatin xoolaha.

Hydroxypropyl Methylcellulose (MHPC)
Hydroxypropyl methylcellulose (MHPC) waa kuwa aan ur lahayn, aan dhadhamin, ethers cellulose aan sun ahayn kuwaas oo lahaa kooxaha hyrdroxyl ee silsiladda cellulose oo lagu beddelay methoxy ama kooxda hydroxypropyl leh biyo wanaagsan. HPMC F60S waa heerka viscosity-sare kaas oo loo isticmaalo dhumuc ahaan, xidhe, iyo filim hore u ahaan jiray agrochemicals, dahaarka, ceramics, koollada, khadadka, iyo codsiyada kale duwan.

Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose (HEC) waa non-ionic, polymer biyo-milmi leh oo laga soo saaray qaab cellulose iyada oo loo marayo taxane ah hababka kiimikada iyo jirka. Marka pH ee xalka 2 ilaa 12, xalku aad ayuu u xasilan yahay. Maadaama kooxda HEC ay tahay mid aan fiicneyn oo ku jirta xalinta biyaha, laguma falcelin doono anions ama cations kale oo dareen la'aan milixda.
Laakiin HEC molecule waxay awood u leedahay in ay dhaliso esterification, etherification, sidaas darteed waxaa suurtogal ah in laga dhigo mid aan lagu milmi karin biyaha ama hagaajinta hantideeda.
